Installing a sink above the washing machine. Shut off the supply of hot and cold water. Sink installation height

In any functional bathroom, in addition to the bath itself, there should be a sink. And this is not only for convenience, but also for aesthetic purposes. The installation of the sink must be carried out efficiently, because your safety will depend on it, and you don’t need quarrels with your neighbors below about flooding. For this reason, pay due attention to the installation of the sink, so as not to encounter unforeseen financial difficulties in the future.

Classification of shells

Modern sinks come in a wide variety of designs. They can consist of one or two sinks, installed on a countertop or pedestal, where communications and a siphon are “hidden”. There is also a semi-pedestal in which the drain outlet structure is fixed. Some sinks are equipped with fastening elements, so the choice of one or another installation method largely depends on the characteristics of the product.

You may be interested in information about how

We are interested in the classification based on installation technology, it looks like this:

• attached to cabinet;
• products installed on brackets;
• on pedestal;
• on special hanging shelf, mounted on the wall.

When buying a sink in a store, pay attention to its dimensions (they range from 30 to 300 centimeters in width), as well as how a particular model fits general style bathroom. Another important criterion is strength.

What will be required at work

1. Actually, a sink.
2. Silicone based sealant.
3. Adjustable wrench, wrench.
4. Dowels.
5. Screwdriver.
6. Screwdriver (if not, use a regular drill).
7. Self-tapping screws (if possible, then with anti-corrosion coating).
8. Pencil.
9. Winding.

Removing an old sink

The first stage of work will be removing the old sink.

Important! Before you begin the dismantling procedure Necessarily the water should be turned off.

First, unscrew the nuts that secure the mixer. Then disconnect the liner and remove the mixer. Remove the siphon connecting the sink to the sewer system - unscrew the nuts (they are located at the bottom), remove the siphon itself and pour the water out of it. If you plan to replace it with a new one, then disconnect it from the drain and then temporarily plug the hole with something (a rag, for example) so that unpleasant odors do not penetrate into the apartment. Finally, remove the sink from its mountings.

Bracket mounting technology

Today, brackets are considered the most popular method of installing a sink. Let's consider the technology of such installation.

Stage 1. Draw a line parallel to the floor surface at a height of about 80 centimeters. This is the base mark from which you will make further calculations. It is at this height that sinks are often installed.

Stage 2. Using a tape measure, measure the thickness of the sink wall that will be adjacent to the wall surface. The resulting figure is the distance that needs to be measured from the base line down and draw another line there. This is where the brackets will be attached. Measure the distance between the brackets and mark their position on the line. The resulting marking is projected onto the base line on the wall.

Stage 3. Place the brackets on the base line, mark where they will be attached and drill holes there. Insert dowels into the holes and secure the brackets to the wall.

Stage 4. The sink is attached to the installed brackets according to the attached manufacturer's instructions.

As we see, there is nothing complicated here if everything is available necessary tools and a natural “eye monitor”. Now all you have to do is connect the remaining elements - the mixer and the siphon, but we will talk about this later.

Installing a sink on a cabinet

An equally well-known installation method is installing the product on a cabinet. This method is characterized by the fact that the installed sinks have a wide variety of shapes and designs. This is an almost universal method, hence its popularity.

To begin with, you make a cutout in the tabletop, but further installation depends entirely on the features of the model, as well as on your wishes. So, you can install your sink on the countertop itself, or deep in the cutout.

Place the product in the resulting cutout and mark the points for future fasteners. Remove the sink and drill holes according to the marks, then put the product back and secure it with bolts. As you can see, the technology is simple; we will only note the methods of attaching the mixer. It can be attached:

• to the cabinet;
• to Wall;
• to the sink;
• to a special stand.

Important! If you wish, you can decorate the sink yourself using real stone or smalt. The only limitation will be your imagination.

Installing a sink on a wall-hung shelf

Wall shelf designed not only to distribute the load from plumbing, but also to hide all elements of the system and additionally serve as a storage place detergents. In a word, function hanging shelf the same as the brackets, there are only a few additional options.

Installation technology

Stage 1:

• Mark the level where the sink will be located.
• Place the sink on it and mark where the fastenings will be. Drill mounting holes.
• Insert plugs for dowels into them, place the sink and secure it.

Stage 2. Mark the fastenings for the shelf. Without removing the shelves, mark on it where the drain hole will be. You also make holes for all the necessary water pipes.

Important! In this case, the mixer is installed before the shelf is installed.

Stage 3. Drill holes in the wall and attach the shelf, making sure the drain hole lines up with the corresponding hole in the shelf. Use dowels for fastening.

Mounting a pedestal sink

Mounted on a pedestal beautiful sink very easy to use and looks amazing. The installation procedure for the pedestal + sink duo is easy, but requires some conditions.

1. Sewer pipes must be hidden in the wall.
2. The height of the drain socket must be at least 50 centimeters.

Here you also install a sink, a siphon and a mixer, only after that attach the pedestal to special studs, pre-mounted into the wall.

Important! If the sink is glass, be extremely careful when installing it so as not to break it!

Installing a corner sink

If the bathroom area is small, then it is more advisable to install a corner sink. This way you make the most of your free space. The technology for installing a corner sink consists of several stages.

Stage 1. Take the corner sink and place it in the place where it will be installed. If the sink will stand on a cabinet, then first place the cabinet and the sink on it. If there is no stand, then install it at a standard height of 80 centimeters from the floor. You lean the sink and mark with a marker where the fastenings will be. You can play it safe and measure everything with a tape measure to make sure the dimensions are correct.

Stage 2. Based on the markings, drill the mounting holes and place plastic plugs in them. Then you lean the product again and tighten the dowels.

Stage 3. Connect the siphon and mixer.

Connecting the mixer and siphon

Now, as mentioned above, we will look in more detail at the features of installing these components. They are connected to sewerage and water supply (both hot and cold).

Important! A siphon is a special valve designed to drain water from the sink and prevent the appearance of unpleasant odors from the sewer in the apartment.

Siphon connection procedure It’s simple: first connect the drain to the sink, then insert it into the drain hole. After this, seal all joints with sealant so that no unpleasant sewer smell leaks into the room.

The only problem that may arise is the installation of the mixer, but this can be dealt with without the help of specialists. For work you will need:

• hose for connecting to water supply;
• fum tape as a sealant.

Stage 1. At the ends of the hoses, attach special rubber rings, the so-called gaskets, which completely eliminate the possibility of leakage.

Stage 2. Connect the hoses to the mixer. Do this carefully, with extreme caution. Screw the hoses into the mixer all the way.

Stage 3. After connecting the hoses, mount the faucet on the sink. All fastenings are carried out using special clamps, which are often included with the mixer (if these were not included in the kit, then buy them in one of construction stores). There are models that are fastened with nuts; they do not require clamps.

After this comes the installation of the sink itself, we have already talked about this.

Conclusion

If you decide to install the sink yourself, then you will have the opportunity to decide for yourself what the structure and each of its elements in particular will look like. A wide range of shapes will allow you to create a true miracle in the bathroom, which will delight the eye of everyone who enters it.

One of the essential elements of a bathroom is a sink, as it is almost impossible to do without it. In addition to the fact that this accessory provides convenient hygiene procedures, it should also fit harmoniously into the interior of the bathroom. It is not always possible to purchase a bathtub, toilet, bidet and sink at the same time, so they are often purchased at different time and from different manufacturers. Despite this, all these devices must form a single ensemble. To choose the right bathroom sink, you need to know what they are, how they differ, and also understand the main advantages and disadvantages of each type.

Types of shells

Unlike kitchen sinks, bathroom sinks come in a much wider range. In order to choose the right accessory, you need to pay attention to the following characteristics:

• type of instalation;
• shape and size;
• manufacturing material.

Types of bathroom sinks by installation method

Based on the installation method, sinks are divided into the following types:

1. With a pedestal. Popularly, this design is also called a tulip. Its main feature is the presence of a leg or pedestal. This solution allows you to hide the siphon and water pipes, and also provides reliable support for the bowl. These structures have a given height, usually 70–80 cm, and if it is not enough, you will have to additionally make a stand or pedestal. It is impossible to reduce the height of the pedestal.

   The pedestal supports the sink and allows you to hide communications

2. Invoices. Such models are installed on the countertop and protrude above it by a distance not exceeding 10 cm. After installing the countertop sink, it seems that it is a free-standing item. Such designs do not have a hole for installing a mixer, so the faucet is mounted on the countertop. For ease of use, the height of the tabletop should be no more than 85 cm.

   The countertop sink is installed on the countertop

3. Mortise. This type of sink cuts into the countertop; this can be done both from below and from above. When inserted from below, the plumbing fixtures are located flush with the countertop, which greatly simplifies the removal of water that has fallen on it. When installing a sink on top of a countertop, it protrudes a few centimeters above it. The mixer can be installed either in the hole on the sink or on the countertop.

   A built-in sink can be mounted either above or below the countertop

4. With wall mounting. This design is also called cantilever. There is no need to install a cabinet or countertop here, since the sink is fixed directly to the wall using special fasteners. There are models of sinks with wide wings that allow you to imitate a countertop. The faucet can be installed either on the sink itself or on the wall. The main disadvantage of such models is that the connection to the water supply and sewer system remains visible. The advantage is to free up free space, and this important point for small spaces. You can install a washing machine under flat models.

   Wall-mounted washbasin saves space

5. Furniture. Typically, such models come complete with bathroom furniture. They can be mounted on a separate countertop, but most often furniture sinks are installed on a stand or bedside table that matches their size.

   Furniture sinks come complete with bathroom furniture

Shape and size

One of the main parameters that you need to pay attention to when choosing a bathroom sink is its size. Only a properly sized washbasin will ensure comfortable use and will not take up a lot of free space.

For small spaces, sinks with a length of 50–65 cm and a width of 40 cm are usually chosen. If you have a large room, then you can install models up to 75 cm long or a double sink, in which case two people can wash at the same time.

Having decided on the size of the sink, you can proceed to choosing its shape. The sinks are:

• round;
• oval;
• rectangular or square;
• complex shape.

Material of manufacture

A variety of materials are used in the manufacture of bathroom sinks:

• Ceramics are the most common products. Porcelain is more expensive and of higher quality, sanitary ware is simpler and cheaper;

  The most common option is a faience sink.

• natural or artificial marble. Although natural marble and a more expensive material, but the presence of pores in it requires more careful care. Sinks made from artificial marble are practically no different in appearance from those made from natural stone, but they are cheaper. In addition, they have a smoother surface, which makes cleaning much easier;

  Artificial marble looks practically no different from natural marble

• Corian is a composite material containing acrylic resins and mineral filler, and with the help of pigment you can apply a coating of any color. Since this material is easy to process, it can be used to make sinks of any shape. Such models have smooth surface, so they are easy to care for;

  Corian can be used to make a sink of any shape.

• glass. Although glass sinks are expensive, they look very beautiful. Special glass is used for their manufacture, so their strength is high. The disadvantage of such models is that they show traces of water, so they need to be looked after more carefully;

  A glass sink always looks stylish and beautiful

• Stainless steel. Such shells have long term service, high durability and hygiene. The disadvantage is that when a jet of water hits, it creates a lot of noise. look after metal models you need to be careful not to scratch their surface.

Preparing for installation

Despite the large selection of bathroom sinks, their installation is almost the same. In addition to the fact that you need to firmly secure the bowl, you will also have to connect the water and drain, and install a mixer. Only high-quality execution of all stages of installation will allow you to install the sink correctly and avoid leaks.

Materials and tools

In order to install a bathroom sink yourself, you will need following materials and tools:

How to shut off the water supply

Before carrying out any plumbing work in the bathroom, you must turn off the water supply. Please note that not only cold, but also hot water is supplied to the washbasin, so you need to turn off both taps. This is done at the entrance to the apartment, and if there are additional taps, then you can stop the water supply only to the bathroom.

You need to make sure that the water pipes and drain can be connected to the selected sink model. If this is not possible, then it is necessary to lengthen the existing pipes or install new ones.

Removing an old sink

If you are replacing an old sink, it must first be removed. The work is performed in the following sequence:

1. Removing the mixer. First, disconnect the cold and hot water, after which the fastening nut is pumped out and the mixer is removed.

   To remove the mixer, you need to unscrew the nut that secures it.

2. Removing the siphon. Unscrew the nut securing the siphon from the bottom of the sink, disconnect it from the drain and drain the water.

   To remove the siphon, you need to unscrew the nut and drain the water.

3. Removing the sink. Remove the sink from its support - this can be a countertop, cabinet or brackets.

   The sink is removed from the support

So that during execution installation work the smell of their sewerage did not spread throughout the apartment; you need to cover the hole in the drain pipe with a rag.

Installation steps

Although when installing sinks different designs There are some peculiarities; the main stages of work are performed in the same way.

Installation work

Before you begin installing the sink, you first need to decide where it will be installed. At this stage the following work is performed:

1. Determination of height. There are no strict standards for the installation height of a bathroom sink. Most experts recommend installing the sink at a level of 80–85 cm from the floor. It all depends on the height of the apartment’s residents. Choose this option so that the sink is comfortable for everyone to use.

   The installation height of the sink should be such that it is convenient for all residents to use it

2. Installation layout:
3. Installation of brackets. To attach the sink to the wall, you need to install brackets. They come complete with the washbasin and match its size. Using a puncher, holes are made in the marked places, plastic dowels are inserted, and then the brackets are fixed to the wall. Mounting a sink on a wall is only possible if its surface is sufficiently strong. When installing a sink with a pedestal, in order to securely fix it, it is also necessary to attach the bowl to the wall. If installation is carried out on studs, it is necessary to use plastic inserts.
   

   A wall-hung sink can only be mounted on a solid wall.

Sink connection

Mixer installation

The mixer can be installed on the sink, on the wall or on the countertop. If it is placed on a bowl, then installation can be done after it is installed, but experts recommend doing this before attaching the sink, so all the work will be easier to complete.

Installation of the mixer is carried out in the following order:

Sink mount

After installing the mixer, the sink must be secured. This stage will differ depending on the chosen model:

1. Fastening the sink to the wall. The bowl is placed on the installed studs, plastic inserts are inserted and the nuts are tightened. If the installation is carried out on brackets, then the bowl is simply placed on them.

   The bowl is placed on the installed studs, plastic inserts are inserted and the nuts are tightened

2. Installation of a pedestal sink. This design can be of two types:
   
3. Installation of a sink with a cabinet. The cabinet is placed, its horizontalness is checked, after which the sink is placed on it. The washbasin can be attached to the wall with studs, but this difficult option. Usually it is glued with a sealant, since the main support is on the cabinet, and the sealant only prevents water from getting between the wall and the sink.

   A vanity sink is usually secured to the wall using sealant.

At this stage, the mixer is connected to the hot and cold water supply system. To ensure tightness between the tap and the nut, a rubber gasket must be installed on the hose. If a flexible connection is used for connection, then the gasket is already installed in it; nothing additional needs to be installed or wound. Then turn on the water and check the tightness of the connection. If a leak appears, tighten the nut a little.

If leaks occur, just tighten the nut a little

Connection to the sewerage system

Now the sink needs to be connected to the sewer system. To do this, first install a siphon. This device can be S-shaped or bottle-shaped. Some sinks have an overflow hole. In this case, you need to install a siphon, which has a hole for installing an additional pipe.

Siphon installation sequence:

1. The siphon outlet is inserted into the sink hole, after which it is fixed. To do this, you need to install a mesh, a gasket and secure the siphon with a screw.

   If the diameter of the sewer pipe larger size pipes from the siphon, use a transition sealing collar

2. Checking connections. After installing the siphon, a control drain of water is carried out. It is checked for leaks; if they appear, they must be eliminated. If a leak occurs from under the sealing collar, then it must be pulled out, lubricated with sealant and a new connection made.

Video: installation of a wall-hung sink

Before you start using the washbasin, you need to check the quality of the connections and how firmly the bowl is installed. To do this, check the quality of all fasteners again. After this, open the hot and cold water tap and check the tightness of the water hoses. If there are water leaks, then the connections must be tightened, and when this does not help, unscrew the hose and rewind the FUM tape.

To check the tightness of the siphon, it is recommended to fill the sink with water by closing the drain hole. Then drain all the water - if there are no leaks in the siphon or hoses, then you can start using the sink.

When draining the water, check the tightness of the connections.

Do not over-tighten the connections, as you may damage the gaskets or strip the threads.

Possible errors and methods for eliminating them

Although installing a sink is not a difficult task, doing it yourself can make certain mistakes. Improper installation not only leads to leaks, but a poorly secured sink can fall and cause injury to household members.

Main errors and ways to eliminate them:

Modern bathroom sinks can have a variety of shapes, differ in the type of installation and the material from which they are made. When choosing, you need to take into account not only the shape and size of the bowl, but also whether the washbasin is comfortable to use. The most affordable and popular are ceramic sinks. Modern technologies allow you to create coatings that repel dirt and are not deposited on them limescale, so they have a long service life and retain an attractive appearance throughout the entire period of operation. If you adhere to the sink installation technology and follow the recommendations of specialists, you will be able to cope with its installation without the involvement of specialists, whose services are not cheap.

Furnishing a bathroom is a responsible undertaking that raises a lot of questions among owners installing equipment. on our own. A wide selection of sinks provides consumers with the opportunity to select equipment to suit any interior.

We will talk about how to install a bathroom sink in accordance with building codes and sanitary requirements. The article we presented discusses examples of installation of built-in and console versions. Taking into account our recommendations, you can handle the work yourself without any problems.

The method of installation of plumbing equipment is determined by the type of sink. Leading manufacturers produce several types of sinks.

The most common are four types of sinks, differing in installation method:

1. Built-in. They are installed in the countertop of a cabinet, table or any other flat surface. Such models are convenient because they allow you to completely hide unattractive communications behind furniture doors.
2. Console. They are suspended structures that are fixed to the wall using a ready-made installation system. Models of this type look stylish and modern.
3. With a pedestal. Models of the “Tulip” series have decorative element in the form of a pedestal on which a massive bowl rests. The drain fittings are hidden inside the support.
4. With a semi-pedestal. Models of this type are also equipped with a pedestal. But it rests not on the floor, but on the wall. Thereby wall models look more elegant. Installation of such equipment is complicated by the need to bring the drain to a given height.

Built-in sinks can be mounted on top of the countertop, fixed with sides around the perimeter of the base, or built into the structure from below.

Regardless of the installation method, the bathroom sinks on sale are very diverse in shape and configuration: oval, round, cubic

In bathrooms where it is not possible to install a countertop of standard width, it is convenient to use semi-built-in models that simply go around the edge of the countertop.

Image gallery

The only caveat is that when installing such plumbing, you will need to install an improvised cabinet, behind the walls of which all communications will be hidden.

Console and built-in models are chosen by owners of small bathrooms, in which every centimeter of space is “calculated”

How to dismantle old equipment?

To dismantle an old device, you must first turn off the water, then loosen the mixer. To do this, unscrew the nut securing it. The equipment is disconnected from the supply pipes, carefully removed and put away.

After unscrewing the taps, you need to make sure that stagnant water or water coming from the pipeline does not leak through the control valve

After this, the drain elements are dismantled:

1. The nuts are unscrewed from the lower outer part of the plumbing element.
2. Disconnect the siphon glass from the drain outlet, empty it of water and clean it of accumulated dirt.
3. Remove liquid from drain and manually Unscrew the locking nut by rotating it counterclockwise.

If the siphon is to be replaced during equipment dismantling, it must be separated from the drain pipe. To do this, unscrew the locking nut located at the connection point between the drain and the water seal, carefully lift the drain and remove the siphon.

Before removing the drain along with the installed gasket, you need to move the wedge-shaped spacer to the side. At the final stage, all that remains is to pull out the outlet pipe with the attached siphon from the sewer socket.

To prevent accumulated water from flowing onto the floor when disassembling elements, it is advisable to install a bucket or any storage container under the siphon

After completion of work to prevent the spread unpleasant odor, the opening of the sewer pipe is carefully closed with a stopper or a piece of fabric folded several times.

If you have to dismantle a sink attached to the wall using combined stands, you should look for the attachment points on the sides, closer to the bottom of the washbasin. If the bowl does not have a floor support, when unscrewing the nuts, the sink should be held with your hands so that it does not fall to the floor under its own weight.

Installation procedure for a console sink

There is nothing difficult about installing a sink in the bathroom without resorting to the services of professionals. The main thing is to strictly adhere to the installation technology, which includes several main stages.

Correct installation of the sink is the key to the normal functioning of the plumbing equipment and ease of use by household members, as well as the absence of regular repair work

To complete the work you will need the following tools:

• electric drill;
• concrete drills;
• building level;
• tape measure and a simple pencil;
• spanners;
• expansion dowels;
• construction adhesive;
• self-tapping screws;
• FUM tape.

Making holes for fasteners

To install the brackets into the outer supporting walls of the bowl from the back, turn the product upside down. The plumbing fixture with installed brackets is moved towards the drawn horizontal line. Along the drawn line, the locations for mounting the fasteners are marked.

At the intended points of future fastenings, using an electric drill, holes are made with a diameter 1-2 mm smaller than the size of the prepared dowels. The fastening screw should fit into the made “socket” with difficulty.

Small portions of glue are poured into the holes to enhance the strength of the joints, then bushings are driven in and support brackets are installed for mounting the bowl

Spacer dowels of nylon or other polymer design are driven into the prepared holes, and self-tapping screws of the appropriate diameter are screwed into them. Then screw in the brackets themselves.

A little trick: so that when making holes the drill bit does not slip on the tile, sticky foam is glued to the area being treated.

Installation of the sink bowl

By tightening the self-tapping screws, check the strength of the fasteners. A sink is placed on top of the mounting pins. Seal inserts and washers are put on the self-tapping screws, and then the structure is carefully tightened. The washbasin is additionally secured with sealant or clips.

When tightening the screws, you do not need to make any special efforts, otherwise the surface of the washbasin may become covered with a scattering of cracks or crack

The task of the master when tightening the washers is to achieve an effect so that the bowl does not swing. The fastening places are decorated by putting on plugs. To prevent the appearance of mold when water gets into the gap between the sink and the wall, this place must be additionally sealed with silicone plumbing sealant.

Connecting the siphon to communications

Installation of the siphon begins with securing the outlet. To do this, install a mesh, a rubber or silicone gasket and a pressure screw in the drain hole. The presence of a gasket is mandatory because it ensures the tightness of the connection.

When installing gaskets, it is important to ensure that they fit the washbasin drain as tightly as possible, without any gaps or displacements.

After making sure that the gasket is installed correctly, tighten the clamping screw, thereby connecting the outlet to the siphon. After this, the end of the outlet pipe, made of hard plastic or corrugated hose, is connected to the sewer socket.

When connecting to a sewer, seals must be used, which can be rubber gaskets or cuffs for corrugations.

Faucet installation process

It is better to install the plumbing fixture before fixing the washbasin to the wall. Once the plumbing is installed, connecting it will be much more difficult. For this purpose, the included mounting pins and flexible hoses are screwed into the mixer.

Using this liner, the connection to the water supply is made. To seal the connections in order to prevent possible leaks, FUM tape is wound.

Water supply hoses are inserted into the hole, having previously put moon-shaped gaskets and washers on them from the bottom side

One end of the hose, equipped with fittings or fastening units, is connected to the mixer, and the other - to water pipes. If there is a discrepancy between the diameters of the pipe and the outlet, put on a sealing collar.

At the final stage of connection, all that remains is to check the functionality of the system and make sure that there are no leaks at the junction of the pipes and cuffs.

You will find a step-by-step guide to installing a faucet on a sink, which we strongly advise you to read.

Assembling and connecting a tulip sink

The bulk of the sink with a pedestal is distributed on a decorative support leg, but the bowl is still attached directly to the wall. The process of installing and connecting this plumbing includes a number of traditional steps. The following photo gallery will help you get acquainted with it:

Image gallery

The details of installing a tulip-type sink are described in detail, the contents of which are entirely devoted to this issue.

Features of installing a built-in sink

Built-in models are embedded into the countertop from below or from above.

Each installation method has its own nuances:

• When installing the bowl on top, it will protrude from one to three centimeters above the surface.
• The lower insertion method is preferable because during operation it is convenient to collect splashes with just one movement.

Regardless of whether the sink is completely recessed into the cabinet, or will be partially raised above the surface, drain fittings will still be located inside the cabinet.

If you are planning to install a built-in sink, be prepared for the fact that you will need to perform perfect processing of all joints

To insert from below, L-shaped fasteners are used, and fixation is performed to the base of the support.

Marking the installation site

Using a template will help simplify the marking of the countertop for installing a recessed sink. Many leading manufacturers include it in the kit for most built-in models.

When determining the location for installing a washbasin, they are guided by two conditions:

1. The sink should not be on the very edge or close to the wall.
2. It should provide easy access and ease of use.

The point of creating the correct markings is to ensure that the washbasin is firmly fixed in the countertop, but does not fall through the hole in it.

In the absence of a template, the shell is turned upside down and applied to the surface. With a simple pencil trace the outline.

The line of the internal contour traditionally recedes 1.5-2 cm towards the center relative to the external line; it serves as a guide when cutting a hole for the bowl

To correctly calculate the distance from the edges of the plumbing fixtures to the fastening eyes, take measurements and transfer them to the outlined outline. The resulting size determines the distance that should be retreated from the line in order to create an internal contour that acts as a support for the sides of the bowl.

Sawing and finishing edges

The hole for installing the bowl is made using a jigsaw. If you have to work with a hacksaw, be prepared to trim the edges.

When working with a hacksaw, in order to get a neat cut, first drill a hole in the area of ​​the marking line inside the outlined contour. Its diameter should be such that the hacksaw blade can fit freely.

Important! To minimize the risk of chipping on decorative coating tabletops, sawing should be done slowly and without excessive effort.

The end surfaces of the created hole are treated with fine-grained sandpaper or sand with a file.

To avoid problems with leakage during equipment operation, the cleaned cut edges of the tabletop are coated with a sealing compound in 2-3 layers.

When choosing a sealant, it is important to focus on the type of material used in the manufacture of the countertop. So for plastic and wooden coverings alcohol-based sealing impregnations are used.

Installing the bowl and connecting equipment

The bowl is installed in the countertop and buried. To ensure a tight fit, the product is turned slightly back and forth. After this, all that remains is to tighten the installed fasteners and remove the silicone with a napkin, which is squeezed out when the bowl is seated in place. The assembled and fixed structure is left for a day until the adhesive composition has completely dried.

To connect the equipment, install a mixer in the hole, connect it to the hoses and fix it with fasteners. The outlet of the siphon is brought into the sink, a pipe is connected to it, which is taken out into the sewer socket.

In general, the technology of the built-in sink siphon is almost identical to that described when installing the console model.

Specifics of assembling a complex from a countertop and an overhead sink, we recommend that you familiarize yourself with the very useful material.

When planning to install a sink located below the table level, it is better to use the services of a professional plumber. After all, this installation method is often chosen for expensive models made of natural or artificial stone.

And this requires not only having at your disposal special equipment for cutting stone, but also knowing the intricacies of working with the capricious material.

Please write comments in the block below. Tell us about how you assembled and installed the sink in the wash area in the bathroom. Ask questions, share useful technological nuances you know, post photos related to the topic of the article.

Specialization: master in construction plasterboard structures, finishing works and styling floor coverings. Installation of door and window units, finishing of facades, installation of electrical, plumbing and heating - I can give detailed advice on all types of work.

Attaching a bathroom sink to the wall is a fairly simple process, but for some reason many people prefer to pay a lot of money for this work. Meanwhile, if you take 10-15 minutes to understand the specifics of the work, you can easily secure the structure without involving hired specialists. I will describe the process in as much detail as possible so that you can understand all the nuances and achieve the best result.

Workflow Description

In order for the result to be excellent, you need to pay attention to everyone important little things, so we will begin our consideration from the moment of choosing the type of structure. After that, I will tell you what is needed for the work depending on the type of base, and then we will deal with the work process itself.

Preliminary stage

I will consider the most common and most popular hanging option, since it is this one that is installed in 90% of all premises. When choosing, there are several important factors to consider:

Design size	Everything is simple here: you must determine how much space you have and, based on this, look for an option with optimal dimensions. A comfortable width is approximately 50 cm, but if there is little space, then smaller sinks can be considered. You should also remember that sinks wider than 60 cm will look bulky in small rooms.
Shape and color	These factors are important to consider because if the design does not fit in with the rest of the furnishings, then all your efforts will go down the drain. It is best to purchase elements from the same collection, then you will get a harmonious interior
Mounting type	I advise you to choose products in which fastening is done using studs. Options with brackets are also quite convenient, but for inexperienced craftsmen I recommend the first solution, since it is much easier to implement and provides very high reliability of fixation
Design option	Concerning mounted options, then it can be either an independent sink or a structure on a pedestal or semi-pedestal. Many people think that if there is a base under the structure, it will bear the load, but in fact, the elements are needed to hide unattractive communications and they cannot support the weight of the sink

Choose products from well-known brands, they are more expensive, but the quality will be much better.

As for the position of the structure, here you also need to take into account several important nuances:

• The standard for the height of a bathroom sink according to SNiP is 80-85 cm, this is how plumbing fixtures are installed in all new buildings. This option is versatile, as it is suitable for people of different heights;

• Let's figure out what modern manufacturers who produce sinks recommend - the height of the bathroom sink, according to experts, can be different. For men, it is most comfortable to use the system if the bowl is installed at a distance of 94-109 cm from the floor, while for women it is most convenient to use a bowl that is attached at 81-91 cm from the floor. The average installation height of a bathroom sink, according to Western experts, should be in the range from 86 to 93 cm; I recommend these figures be used as a guide;
• But the final decision at what height to hang the sink still depends on you; if you have very tall or very short people in your family, then it makes sense to take into account their anthropometric parameters.

If you have children then the best solution installation may be separate. The most important thing here is that the area of ​​the room is sufficient.

If you hang a mirror, its location is determined individually, since the dimensions of the structure and its shape can be very different. You also need to take into account the height of all family members; if the difference is large, then it is better to hang a large size option, this will be the optimal solution. The minimum distance between the mirror and the sink is 25-30 cm, this will prevent splashes on the surface when washing your hands.

And another simple one, but important advice- if the sink is being replaced, then the new version should match the old one in size, this will significantly simplify the work and you will not have to carry out large-scale alterations.

Preparation of all necessary materials and tools

It is impossible to carry out work if you do not have everything required at hand, let's start with the list of materials and components:

• First of all, you need the sink itself; it can be either wall-mounted or have additional elements in the form of a pedestal or half-pedestal;
• As for the fasteners, most often they are included in the kit, but sometimes the quality of the elements leaves much to be desired, and the length of the studs may not be sufficient for your base. I always buy new dowels (I’ll tell you how to choose them below), and as for the studs, new elements are needed only if the standard ones are not long enough;

• If your sink is made with brackets, then you need to purchase these fasteners separately. They may come in different configurations, so when choosing, make sure the product fits your product configuration. A separate type is adjustable structures, they are good because you can change the height if necessary;

• You also need to make your choice responsibly; it’s better to spend a little more money than to later think about how to eliminate the smell from the bathroom sink. Choose products made of good quality plastic with a sufficiently long length. flexible pipe– if it is strongly strained, then after a few years a leak will certainly form at any connection. Frequently asked question from this area of ​​“what to do - the sink is clogged?”, everything is simple here: choose those options that can be quickly sorted out if necessary;

• If the faucet will be fixed to the sink, and this option is the most common, then its choice should also be taken responsibly. It is necessary to take into account the width and depth of the sink to select the length of the faucet and the height of the gander, otherwise water will splash around. Again, try to purchase high-quality options, and not cheap Chinese ones that last a year or two.

Now let’s figure out which tool needs to be assembled before attaching the sink:

• In order to attach studs or brackets to the wall, you must have a hammer drill with a drill of the appropriate diameter and length on hand. Most often, dowels with a diameter of 12 mm and a length of at least 70 mm are used, based on this optimal size drill 12x120 mm;

If you are attaching the structure to a surface lined with ceramic tiles, then do not forget to purchase a special tile drill so as not to spoil your finish and make a neat hole.

• To fix the sink, you need to tighten the nuts; most often a 14 or 13 mm wrench is used; the easiest way is to have a 13x14 open-end or sleeve version on hand, although with the current wealth of manufacturers you may have a different size. Manufacturers from the Middle Kingdom often complete sets with strange 12 or even 15 nuts;
• For determining correct position design, you need a tape measure, and in order to secure it evenly, you cannot do without building level. Marking is done using a pencil or felt-tip pen - whichever is more convenient for you.

Installation of the structure

Before you install the sink, you need to carry out a number of works. All necessary communications must be connected to the location of the structure, this applies to sewerage and water supply. If the location of the sink is moved, then a whole range of plumbing work will have to be carried out.

If a Tulip sink is being installed, then the sewer outlet must be located exactly under the sink, otherwise problems may arise with attaching the pedestal.

Now let's look at the installation process; the instructions for installing the sink look like this:

• First of all, you need to use a tape measure to mark at what level the sink will be located., let me remind you, standard height equal to 80-85 cm, but you can hang it differently. Next, use a level to mark the horizontal line; it will serve as a guide for all further work. It’s best to use a sink to mark the locations of the fasteners, so you definitely won’t make a mistake and won’t make extra holes;
• Next, you need to make holes in the marked places; if the fastening is on studs, then there will be only two points. If you have brackets, then each of them should have 2-3 attachment points, it all depends on the configuration of the elements. If your surface is tiled, then first the ceramics are drilled with a special drill, and then the work is carried out using a metal drill;
• Then you need to attach load-bearing elements, first, dowels are driven into the wall, after which studs are screwed into them. If brackets are used, they are fixed using driven screws, everything is very simple and clear. It is important that the elements are positioned at the correct width;

• Now let's figure out how to fix the sink to the wall, everything is quite simple: the structure is put on the studs, and then pressed with the help of nuts. To avoid damaging the ceramics, there is a washer under the nut; the fasteners must be tightened with moderate force. The structure is simply placed on the brackets; some models provide fastening; it is important to ensure that the sink does not move;

• Next, the mixer is installed; it is most often secured with studs. If your sink design is such that access to it will be difficult after mounting it on the wall, then it is better to install the mixer in advance. Modern systems easy to install, and you can easily figure out how to install the product correctly, because it always comes with instructions;

Attaching flexible hoses is not the most difficult job

• The siphon is also very easy to install, the most important thing is to place it carefully sealing elements and when clamping the fasteners, do not crush them. Assembly usually takes a few minutes; it is important to do everything carefully and not damage the threaded connections;

• As for the pedestal, I noted above that it has a purely decorative function and is not designed for loads. The element is fixed to the floor using dowels, and the joints between the elements are sealed with special gaskets. Naturally, if you make a mistake with the height, the element may not fit into place or there will be a wide gap between it and the sink, so it is better to check all matches at the initial stage.

At the end I would like to add a small note - before installing the sink on the brackets, you can coat the joint liquid nails, this way you will achieve excellent fastening if the structure is not fixed with additional fasteners.

It is best to seal the joint between the sink and the wall silicone sealant. People ask me how to seal if the seal is cracked, everything is simple: the old sealant is removed and the gap is filled with new one, the color is selected depending on the color of the sink.

In a nutshell, I’ll tell you how to install an overhead sink. This option is being used more and more often, but many do not understand how easy such systems are to install:

• The mixer is always mounted separately– either to the countertop or to the wall, you need to choose the optimal solution;
• The sink is located directly on the surface; no cutouts are needed for it. The only hole that needs to be drilled is for the sewer outlet;
• Fastening is very simple: the lower part is coated with silicone or moisture-resistant liquid nails and glued to the tabletop, everything is very quickly and reliably.

Conclusion

Fixing a sink in a bathroom is not the easiest job, but it’s hard to call it difficult either. The process takes little time, and if done correctly, you can enjoy the results for many years. The video in this article will provide additional information on the topic, and if you have questions, please comment below.

The eternal problem of lack of space in the bathroom or combined bathroom of standard city apartments forces us to invent various ways saving space. Responding to such consumer requests, plumbing manufacturers do not stand aside and are developing a variety of product options that will help solve this problem. One of the interesting and very rational approaches is to install a sink above the washing machine, which will not only save space in the room, but will also add an unusual touch to the design of the bathroom.

These sinks have an elegant appearance and original form, so they fit perfectly into any interior style. However, it should be remembered that choosing a sink for an already purchased washing machine will become much more difficult, so it is recommended to plan a comprehensive purchase. Some manufacturers make kits that include both elements at once - they are already matched to each other in their layout and fit perfectly together.

Sinks designed specifically to be installed above a washing machine or any cabinet are often called “water lilies.” Most likely, they got their name due to the characteristic shape and non-standard location of the drainage system.

Sinks designed to be installed above washing machines, commonly called "water lilies"

The drain in these sinks is not located in the central part, like most conventional sinks, but closer to the back of the bowl.

Sink appearance

"Water lilies" can have various shapes- square, oval, rectangular, with straight and rounded corners. Models with non-standard and completely unusual configurations are also produced. Therefore, there should be no problems with choosing a sink based on this criterion.

A variety of models allows you to choose a water lily sink for a specific bathroom design style

Sink-sinks of this type, unlike ordinary sinks, may have a mounting hole for installing a faucet not only in the center of the rear “shelf”, but also in any other place, or EVEN not have it at all.

In addition to the variety of shapes, this type of sink is produced in a wide range of shades. They may also differ in the main material of manufacture. In a word, based on the totality of these criteria, a “water lily” can also be selected to suit every taste and color.

This type of washbasin is made from ceramics, acrylic, glass, metal, and in addition to Lately products made from a polymer-based material called polymer concrete or artificial stone. The advantage of the new type of shells is their high resistance to all types household chemicals and mechanical influences. Polymer concrete can imitate a natural stone and have any color shade. All these criteria, as well as the variety of shapes of products made from this composite material, determine the breadth of the range and large selection possibilities.

Dimensions of the water lily shell

Appearance – appearance, but still, when choosing a sink for installation above a washing machine, its linear characteristics should be in the foreground.

Sink sizes may vary, and when choosing products for installation above specific model washing machine, you need to remember that the washbasin bowl should be slightly larger than the size of the appliance installed underneath it. This criterion must be taken into account especially in cases where the control panel of the washing machine is located not on the front panel, but on the top panel.

The dimensions of the “water lily” should prevent water from entering the control panel washing machine

Let's pay attention to the diagram. For narrow washing machines with a depth (M) of 360÷390 mm, the corresponding sink size (L) should be 500 mm, and for large machines with a cabinet depth of 500÷510 mm, you should choose a washbasin with dimensions from the outer edge to the wall at 600 mm.

Why is this being done? There must be a gap (H) between the household appliance and the wall so that the supply and drain hoses of the machine, a siphon drainage system from the sink, and a flexible connection to the mixer can be placed there quietly, without pinching or twisting. Drain hoses connection to a sewer pipe (50 mm) is required. The pipe, of course, can be hidden in the wall, but the connecting pipe still requires no less distance. In a word, clearance (H) is necessary in any case, and it is usually taken equal to 70 mm.

The diagram also shows the most typical locations for sink drain holes (item 1) and faucet installation (item 2). This asymmetrical arrangement provides a significant gain in overall compactness.

The height of the washing machine can be any of the available standards, but if the sink installed above it will be used by children and short people, then it is recommended to choose the device itself, if possible, as low as possible. Therefore, before purchasing a kit, you need to take careful measurements and determine the maximum allowable height.

An important role for general security operation plays a role in the depth of the sink bowl, which is very important to consider by choosing the right size.

Draining a water lily sink

The drain for sinks of this type can have different configurations and is arranged in a non-standard way, but is always located in an area as close as possible to the wall. The hole can be regular, round, or original, made in the form of a narrow slit. It can be located in a kind of niche-recess, under the soap dish - in this case it is usually located in the lower rear area at the junction of the bottom and wall or on one of the sides of the sink.

The narrow drain slot is convenient because the siphon in such a system is located at the back of the sink, completely outside the washing machine body.

However, such a system also has its drawback - the narrow drain often becomes clogged and requires frequent cleaning, otherwise an unpleasant odor will begin to emanate from the siphon.

Water lily sink with overflow system hole

Some models of water lily sinks are equipped with a drain-overflow system, which prevents even accidental overflow of the bowl with water, pouring over the edges and getting into the washing machine. The drain and overflow “windows” are usually located in the same way as on standard sinks, in the lower and side areas of the bowl. In addition, the drainage system is often equipped with plugs or even equipped with automation.

Video: a short review of water lily shells

Choosing a washing machine

Some manufacturers produce washing machines specifically designed for installation under the sink. From famous companies Such models are manufactured by Zanussi, Electrolux, Eurosoba and Candy. Basically everything similar models designed for small loads of laundry - usually up to 3.5 kg.

Many owners of even small bathrooms, not intending to sacrifice the performance of washing machines, purchase models standard sizes with a larger load. However, the height of the residents should also be taken into account, since the sink, with a washing machine height of 700 mm, will be raised to a level of approximately 890÷900 mm from the floor, and with a height of 850 mm - even up to 1040÷1050 mm .

Options for placing a water lily sink on the wall

As mentioned above, the depth of the washing machine must correspond to the same parameter of the sink, taking into account the required clearance at the wall - this criterion must be met not only for comfortable use of the washbasin, but also to ensure electrical safety.

Perhaps the most rational decision- this is the purchase of a ready-made kit, despite not the highest loading rates of the washing machine

But still, if you have the opportunity to purchase a set of equipment, then it will be most convenient to go with this option, since you won’t have to invent or adapt anything. In the kit, the manufacturer has already taken into account not only all the dimensions, but also the external design of the elements - they look together as a single whole.

What makes up the total height of the working panel of a water lily sink?

In the diagram presented as an example, you can see what will make up the total height of the working upper surface of the sink. This is the height of the washing machine itself and, taking into account its adjustable legs, the height of the brackets, plus the thickness of the front edge of the sink itself.

But if the flat drain siphon is located under the sink, then its height should also be taken into account.

The diagram shows examples of correct ( A ) installation of the machine, and performed with typical mistakes:

b - Mismatch between the siphon type and the selected installation scheme – a drain pipe The sink has a sharp turn at a right angle, where blockages will inevitably form over time.

V - discrepancy between the sizes of the sink and the washing machine, the front panel of which remains completely unprotected from water entering from above.

Disadvantages of water lily shells

Having decided to carry out a comprehensive installation of a washing machine and sink in this way, it is necessary to take into account the disadvantages of such a scheme so that they do not become a surprise during everyday use. Many are ready to put up with any disadvantages of such a complex in order to save space; some simply have no choice but to use such a design. But it is quite possible that for some these shortcomings will seem unacceptable.

The disadvantages of this installation include the following nuances:

• From the design of the sink presented above and the elements attached to it, it can be understood that for its functioning a flat siphon for drainage is required. If for some reason the washbasin is not equipped with all necessary details for the drainage system, it will be extremely difficult, and sometimes almost impossible, to find components separately. The same thing awaits the owner of such a complex if, for some reason, even one of the elements of the system fails.
• As a rule, this type of sink is equipped with a hole for draining water from the bowl, which is located in its side part, and not traditionally in the center of the bowl. This circumstance in itself can cause a certain inconvenience, since often the water does not leave the bowl completely, and you need to take care of its removal yourself, using a sponge or soft cloth. Water retention also occurs in the flat siphon, which leads to frequent blockages. The same problem can arise with the already mentioned narrow slot-like drain holes.
• Another problem that you will have to face when installing such a kit is directly related to the washing machine itself. Until you develop a stable habit, you will have to hit the bottom of the appliance with your feet more than once when approaching the washbasin. The space under the sink is full, and therefore standing close to it will be uncomfortable at first. In order to create at least a minimum space for easy access to the washbasin, you will have to choose a narrower washing machine and a wider sink that protrudes in front of the washing machine body. However, it should be remembered that machines of compact depth do not have a large load of laundry. We will have to make some kind of compromise, look for a “golden mean”.
• If the sink is chosen and installed incorrectly, then the problem of protruding corners of the washing machine will arise, which can create inconvenience not only when washing, but also when moving around the bathroom.

Despite these “cons,” the scheme is still growing in popularity. In cramped apartments, there may not be any other place to install a washing machine, so many homeowners simply “turn a blind eye” to the shortcomings and inconveniences.

Installing a sink above a washing machine

When installing a sink and washing machine, you won’t have to invent anything, since it is done, in principle, in the same way as when installing standard models.

The entire process of installing a sink can be divided into several stages - marking, installing brackets, assembling the product, equipping it with a mixer, installation and connection to the sewerage and water supply.

If we talk about the installation sequence, the sink is installed first and necessary elements to connect the washing machine, and only after that the device itself is installed.

If you plan to install the washing machine almost close to the wall, then the water and sewer pipes in advance of installing the washbasin, you need to embed it into the wall, leaving only pipes (water outlets) outside the wall, to which access will be provided for connection and control.

The brackets must exactly match the selected water lily sink model

• The first thing you need to do is make markings on the wall to secure the brackets. They usually come with a sink. If they are purchased separately, then when buying a washbasin, you should immediately ask the seller to select brackets for it, since they come in different types and not all are suitable for a particular type of sink.
• The brackets are attached to the wall using dowels or anchors. But they are initially not hammered in (not tightened) to the end; a small gap of 3÷5 mm is left between the wall and the bracket, which will help to accurately adjust the horizontal position of the sink.
• After this, you can proceed to assembling the washbasin. A mixer is attached to it, to which flexible pipes for supplying hot and cold water.

Don't know how to properly install a faucet on a sink?

The scheme for both the washbasin in the bathroom and for kitchen sink- approximately the same. The sequence of operations is outlined in a special publication on our portal.

• Then the drain-overflow system is connected, if provided for by the design. After this, a drain siphon and a drainage pipe coming from it are installed. It is important to pay Special attention the tightness of all connections of the system, since there should be no possibility of the formation of even small leaks. To do this, you should install all the sealing gaskets provided by the design, and some elements may need to be “planted” with silicone sealant.

• The next step is to try on the sink, installing it on the brackets and setting it strictly to the level. If the fastener kit includes a support hook, then mark the location of its installation. After this, the brackets in the exposed position are rigidly attached to the wall, completely tightening the dowels or anchors. The sink must be temporarily removed to avoid accidental damage.
• Then, a hole is drilled in the wall into which the hook will be installed, and a dowel plug is driven into it.
• After this, the sink is installed back. A hook is inserted into the hole and carefully twisted until it stops. Before installing the bowl on the brackets, it is recommended to apply sealant to the area where the sink touches the metal and let it dry. This gasket will protect the sink cover from damage.

• The last step is connection drain system to the sewer pipe, and then flexible hoses for the mixer supply are connected to the pipes supplying hot and cold water.
• After the sink is connected to all communications, the washing machine is carefully installed under it, adjusting its position with screw legs to ensure complete stability and stability during operation.
• The drain pipe from the washing machine is also installed in the pipe prepared for it (often it is located on the siphon part of the drain system of the sink itself. Then the machine is connected to cold water to the corresponding pipe with a tap (water outlet). After this, all that remains is to open the taps on all supply pipes water, insert the power plug into the socket - and the complex can be used.

It should be noted that there is a simplified option for supplying water to a sink installed next to the bathtub. It consists in the fact that for two plumbing fixtures (sink and bathtub) one mixer with a rotating long spout is provided.

If you use this option, you can not only do without a second mixer, but also free up the space behind the washing machine from additional connections. In this case, the “water lily” sink needs to be installed in such a way that it rests slightly on the edge of the bathtub, slightly overhanging it, since when turning the mixer spout to one side or the other, water can get onto the panel of the washing machine.

Having finished installing the sink and washing machine, before starting to test them, you should once again check the locations of all connections of pipes and hoses, since even a small leak and water getting into certain parts of the washing machine can lead to dangerous consequences, to the risk of short circuits, breakdowns in phases of the housing and the likelihood of electrical injury. It is recommended to use a power supply network with a grounding loop for the bathroom, and connect the machine itself through a protection device - an RCD.

So, for a small bathroom, installing a sink above the washing machine is often the only option. But at the same time, it is extremely important to provide in advance for ensuring the general safety of such a complex during operation, the correct relative position of the sink and the machine, as well as the tightness of all connections.
