According to the current SNiP, the installation of plumbing equipment (including the toilet) is carried out in compliance with certain rules, which guarantees a long operating time. Many companies provide installation services, but you can do this operation yourself and save decent amounts.
Before we figure out how to attach the toilet to the floor, let's get acquainted with their known types and find out the design features.
Toilets differ in the following characteristics:
- the device of the tank and the drain bowl, the method of their articulation;
- sewage flow direction (direct or lateral);
- the material from which the toilet is made;
- dimensions and total weight.
When considering the installation of toilets in this class, the focus is on the first point (that is, design differences).
Reliable fastening of the toilet bowl to the floor can be obtained provided that its design features are taken into account.
These plumbing samples are of two types:
- models with a tank, which is mounted on the ledge of the bowl from its back side
(the water tank is adjacent in this case directly to the wall of the toilet);
- monoblocks, in which the bowl and drain tank are made as one module, do not
with detachable parts.
The advantage of the combined version or monoblock is the ease of maintenance of the toilet, including its repair. To this should be added the relatively low noise of the flushing procedure in comparison with a typical separate design.
The disadvantages of this class of plumbing fixtures include a noticeable decrease
pressure of the drain mass.
Let's figure out how to fix the toilet bowl to the floor in the toilet.
There are three methods:
- mounting on dowels (bolts),
- on glue
- taffeta fixation.
Let's consider each of these toilet attachment methods in more detail.
Mounting with dowels (bolts)
This method is the most practical and does not require large expenditures. He also
provides a secure mount for the toilet, provided that the floor screed
prepared for installation.
Small irregularities do not impair the tightness of the installation, since in this case an elastic gasket can be used.
Fixing the toilet bowl to the floor with bolts is suitable for both conventional structures and
light, compact, that is, this option can be considered universal.
Bolts for fixing the toilet to the floor allow you to get a tight connection,
if a sealing gasket cut from a piece of linoleum is used
or elastic rubber.
These blanks are placed under it, and then outlined along the contour with a marker. Immediately after this sharp knife (sometimes scissors are used for this), a sealing element, corresponding in shape to the supporting part of the product.
Before fixing the toilet to the floor, markings are made on the surface of the screed
specially for dowels, into which the hardware is then “driven”. The latter are usually included
included with the device to be installed. In their absence, special bolts for
floor mounts are available from a hardware store.
The order of further operations looks like this:
- First, a purchased toilet is placed on an already prepared place for fitting, and
then outlined along the contour with the same marker. - Then the toilet is removed, and the marked place is coated with a sealed composition,
on which the previously prepared gasket is glued.
Additional information: in some cases it is possible to do without sealing, but for this the floor surface in the toilet must be well leveled beforehand. - Before attaching the toilet to the prepared surface, you need to
prepare holes for metal dowels, for which a drill with
diameter slightly larger than the size of the hardware. - Then the same holes are made at pre-marked points.
glued pad. - Now it will be possible to hammer the dowels into them and carefully install them on the gasket
toilet for subsequent fixation. - Bolts for fixing the toilet to the floor should be screwed in very carefully, without
efforts, being careful not to damage the ceramics.
Violation of this rule when handling tools and hardware can lead to
the appearance of cracks or chips in the attachment points.
This is unacceptable - the bowl will then become unusable. After fixing, they proceed to the connection to the sewer, paying attention Special attention connection of the corrugation of the drain channel.
For education hermetic connection its ends are abundantly lubricated with silicone,
one of them is inserted into the socket sewer outlet, and the second is put on
outlet neck. In the course of installation, the joints are carefully crimped with palms,
which will allow the hermetic composition to quickly soak into the material of the corrugations and form
reliable contact.
To obtain a tight connection, the place where the toilet bowl is drained can be additionally sealed with metallized tape.
At the end of all these operations, it's time to connect the plumbing
outlet, and the plumbing fixture is completely ready for operation.
Glue fixation
A reliable mount for the toilet can also be designed with the help of an adhesive composition,
bought in ready-made or handmade.
This method is considered the simplest, but at the same time fastening without bolts will require a lot of time (it takes 12-15 hours for the epoxy adhesive to fully cure).
Another condition for obtaining reliable fastening is as follows. Before as
glue the toilet to the floor, you will need to carefully level the surface of the screed or
cover it with thick floor tiles.
When figuring out how to glue the toilet to the floor or tiles, preference is usually given to special epoxy resins, prepared according to the instructions attached to the composition.
The method of attaching a sanitary ware to adhesive composition simple for this
you will need to do the following preparatory operations:
- First, the working surfaces are cleaned of dust and dirt residues.
Before gluing the toilet on the tile, it is desirable to give it a small
roughness, for which you can use a large sandpaper - this technique helps to improve the adhesion of the surfaces to be glued.
- Then they are degreased with a solvent or ordinary acetone, then
you can proceed to the preparation of the glue. It can be bought in the store ready-made
or cook it yourself.
To do this, you will need: 100 parts of ED-6 resin, 200 parts of high-grade cement, 20 parts of solvent and 35 parts of hardener.
When preparing the adhesive composition, the sequence of actions is important, which determines
the order in which individual components are added to it.
First of all, you should heat the resin to 50 degrees, and add a solvent to the thick solution. It is followed by the addition of a hardener and at the very end of the procedure cement is placed there. In the process of adding the components, the mixture must be continuously stirred, as a result of which a homogeneous and dense plastic mass should be obtained.
For better fixation of the plumbing fixture on the screed or tile of their surface
pre-cleaned and lubricated with a not very thick layer of prepared adhesive
mixtures.
Upon completion of installation, excess epoxy composition up to 4 mm thick, squeezed out by the mass of the device, is immediately removed with a damp cloth.
It is advisable to use the mixture prepared for installation within one and a half hours. Otherwise, it will freeze and become unusable.
When installing a toilet bowl, you should carefully ensure that its socket is located strictly opposite the sewer drain hole. If this is not observed, you need to forcefully press the base to the floor.
Upon completion of these operations, the device is left for about 12 hours, necessary for the final curing of the adhesive. After the specified time, you can proceed to connecting it to the water supply and sewerage.
Taffeta fastening
When choosing fasteners for a toilet bowl to the floor, take into account the possibility of mounting it on wooden floor, which is usually required in private buildings. In this case, you will need a special gasket made of durable wood (it is called taffeta).
For its manufacture, a board 28–30 cm thick is taken, corresponding in size
the form of a toilet stand. In order to protect against moisture and destruction of its surface
covered with a layer of drying oil.
To correctly install the toilet on tile follow our step by step instructions with photo and video.
Working time: ~ 1 hour.
Total time: ~ 24 hours.
Preparing a room for a toilet
It is better to install the toilet bowl in a completely renovated room so as not to damage the plumbing. You should have a hole ready for the outgoing sewer pipe, as well as a water outlet for the drain tank.
Tools and materials required for proper installation
To install the toilet, we need the following tools and materials:
- Adjustable wrench
- flexible hose
- fum tape
- Pencil or marker
- Yardstick
- Hammer
- Dowels and bolts (should come with the toilet)
- Sanitary lubricant
- liquid silicone
- rubber spatula
How to properly install a toilet bowl with your own hands
Step 1. Eyeliner to the drain tank
Shut off water access to the system. Unscrew the plug on the water outlet using an adjustable wrench. A crane must be connected here. An angled or straight faucet of your choice can be used. Seal the threads on the faucet with fum tape and screw the faucet into a water outlet. If using a corner tap, screw it in so that it points down. Shut off the faucet valve.
screw flexible eyeliner to the faucet outlet. It is not necessary to use a fum-tape, since a sealing gum is provided in the design of the flexible hose.
Step 2. Marking the toilet installation guide
To install the toilet exactly in the middle of the toilet, measure the width of the room against the wall and mark the middle with a pencil. Do the same in the middle of the room and draw a line along the two marks. This line will be our guideline that determines the direction correct installation toilet.
Step 3. Assembling the sewer drain
If necessary, supplement the sewer drain with an angled pipe (45-90 degrees) so that its opening looks towards the outlet pipe of the toilet bowl at a smoother angle.
Advice: To make it easier to connect two pipes, use plumbing grease. Apply it on inner surface drain hole (lubricate the rubber o-ring) and on the outside of the elbow pipe that will enter the hole.
The sewer drain can be connected to the outlet of the toilet in two ways:
- hard plastic adapter;
- flexible corrugation.
In both cases, when inserting connecting element use plumbing grease as above.
Step 4. Preparing the base of the toilet and marking it on the tiled floor
Advice: Do not pre-connect the tank to the toilet. When and how to connect the tank to the toilet, you will learn later in the article.
Take the base of the toilet and turn it upside down. The edge of the supporting part of the toilet must be smooth, without defects. Clean it up if necessary with a sharp knife.
Place the toilet base on the floor at the installation location. Follow the line you drew earlier (see step 2) to position the toilet correctly and exactly in the center of the toilet. Additionally, check the correct installation by measuring the distance from the toilet to the left and right walls with a tape measure.
Connect the toilet pipe to the drain system adapter and outline the perimeter of the toilet base with a pencil or felt-tip pen - this will help you install it in the future without additional measurements. Also, on both sides, mark the locations of the holes for fasteners.
Step 5. Fixing the toilet to the tile floor
Set the toilet aside and drill holes in the tile for fasteners. Use a special tile drill. The depth of the holes should be equal to the length of the dowels that come with the toilet. Hammer plastic dowels into the holes drilled in the tile.
Put the toilet back in place along the drawn lines and connect it to the sewer drain. Screw the metal screws with washers that come with the toilet into both mounting holes, but only halfway.
Step 6. Additional fixing of the toilet bowl with liquid silicone
Raise the toilet bowl by 0.5-1 cm, place any supports in two or three places (use what you have at hand - plastic, pieces of tiles, etc.). Very carefully inject white liquid silicone into the gap between the base of the toilet bowl and the floor tiles. Do this around the entire perimeter of the base of the toilet. Raise the sides of the toilet bowl with your hands and, taking out the stands, add silicone. Silicone should be evenly distributed around the entire perimeter of the base of the toilet and create a plentiful "cushion".
Lower the toilet and tighten the fixing screws all the way by hand (without excessive force). Remove excess silicone that is outside with a plastic spatula moistened soapy water. Form a beautiful edging around the entire perimeter of the base.
It is necessary to wait a few hours (see the curing time of the silicone on the packaging), and only then proceed with the installation of the toilet.
How to install a toilet flush mechanism
On the thread of the main drain device put on the gasket and insert it into the technological hole of the drain tank. WITH reverse side tighten the wide nut with your hands - do not use tools to avoid splitting the tank.
Advice: We recommend installing a locking device that controls the flow of water into the flush tank after installing the flush tank on the toilet bowl. This will make tightening the mounting screws more convenient - you will not be disturbed by an extra mechanism inside the tank.
When installing the locking device, check for burrs on the bottom of the device where the hose is put on. Remove bumps so that the further connection is tight. Insert the locking device into the hole in the tank intended for it and tighten it from the back with a plastic nut. Again, do not use any tools, tighten the nut by hand.
How to install a cistern on a toilet
After the silicone is fully cured and assembled drain mechanism tank, you can proceed to install it on the toilet.
Between the drain tank and the base of the toilet bowl, it is necessary to lay a soft gasket in the form of a ring (comes with the toilet bowl). Then slide the cistern onto the toilet so that the holes for the tie screws on the toilet align with the holes on the cistern. The connecting screws must have a plastic flat washer and a rubber cone. Insert the fixing screws into the holes of the drain tank and twist them on the other side with plastic nuts (horns). When tightening the screws, make sure that the tank is horizontal.
Screw the flexible hose that supplies water to the fitting at the drain tank. This connection does not require the use of a fum tape, since the connection will occur through a rubber gasket.
The installation of the cistern on the toilet is completed, you can open the faucet and check the flow of water, as well as see and eliminate possible leaks in the system.
Put the lid on the drain tank so that all the elements of the trigger mechanism enter the hole. Screw the release button into the hole. Check the functionality of the button. At this stage, the installation of the toilet cistern is completed.
How to install a seat and lid on a toilet
The simplest remains. Attach the seat to the toilet and thread the mounting screws through the holes. Without much effort, tighten the screws on the back of the toilet with nuts. Toilet seat installed.
Video lesson: How to properly install the toilet on the tiled floor in the toilet
Work completed. You installed the toilet with your own hands and, rest assured, you did it right!
If you deal with the issue of installing a toilet bowl, then you can save a lot on the services of plumbing specialists. And do not be afraid of this work, because there are no special technological processes. The main thing is to get to the heart of the matter, study the material provided and consolidate the whole theory with the video material you have watched.
In this article, we will tell you about the popular ways to fix the toilet to the floor. It should be said right away that we will not describe the technology of concreting the toilet bowl, it is gradually becoming a thing of the past. Now the toilet is installed directly on the tile and it is important to understand the methods of its fastening.
Dismantling works
First of all, it is necessary to carry out installation work to remove the old device. All this work should not take long. First of all, the valve for supplying water to the tank is closed. After that, the nut on the hose is unscrewed. The tank is draining water. Next, the mount on the tank is dismantled.
Helpful advice! If the mount is metal and it is slightly rusted, then it will be problematic to unscrew the nut. In this case, you can use special formulations, for example, WD-40. In just a few minutes, the rust will go away, and you can easily unwind the fasteners.
After that, the fasteners on the toilet itself are dismantled. Usually these are anchors twisted into the floor. If you still have old toilet, then it can be cemented. In this case, you need to carefully break the screed and completely remove the old toilet.
If there are no plans for it or it is already flowing, then you can break the toilet itself, in which case dismantling will be facilitated. But remember, this is acceptable if it is concreted!
During the dismantling process, be sure to follow the safety precautions so that the fragments do not damage unprotected areas of the body. Plus, you need to carefully remove the toilet from the sewer pipe. If it is damaged, the installation process may be difficult.
Foundation preparation
After complete dismantling the foundation for the installation of the toilet should be prepared. The amount of work will depend entirely on the quality of the floor. If there is a tile on it and you do not plan to replace it, then just make sure that it is securely held. If you remove the old tile and lay a new one, then you should not rush to install the toilet.
If the old device was concreted and a hole formed in the floor after its removal, then it must be completely cleaned and cemented. It is also important to pay attention to the outlet of the sewer pipe. It must be intact to exclude the possibility of leakage. waste water. If you have cast iron pipes, then immediately plan to replace the pipe with a plastic one.
Tools
To fix the toilet with your own hands, you need the appropriate tool. Most home craftsmen have it. In particular, you may need:
- Perforator.
- Wrench.
- Hammer.
- Roulette.
- New flexible hose.
- FUM tape.
- Fasteners.
- Sealant.
This is the main set of tools. Its configuration may vary slightly, depending on the method of installation.
Instructions for fixing the toilet bowl - 3 ways
So, we suggest that you familiarize yourself with three ways to fix the toilet:
- With the help of dowels.
- For glue.
- On taffeta.
Although the technology is different, the task remains the same - to securely fasten the toilet to the floor so that it does not fall during its operation.
With dowels
If you have a flat floor, then this method is the most common. But a perfectly flat tile floor is important here. If a small difference falls into the place of attachment, the toilet bowl may crack.
To prevent this from happening, you can put a rubber lining or a piece of old linoleum under the toilet. To cut it out, you need to put the toilet bowl on the material, circle the outline with a marker and then cut out the given shape.
After that, marking is carried out directly on the floor. In most cases, toilet bowls have two mounts. The markup process is as follows:
- Put the toilet in the intended place.
- Outline its outline on the floor.
- Place marks where the mounting hole will be drilled.
- You remove the device and apply a sealant to the floor, with which the lining selected and cut out by you will be glued.
While the sealant hardens, you can begin to make a hole. The quality of fastening will largely depend on the correctness of the selected drill diameter. It must fully correspond to the diameter of the dowel. You can drill through the gasket.
A plastic dowel must be hammered into the prepared hole. After that, we install the toilet in place and fix it with dowels. The device should be properly pulled, but moderately, otherwise the tab on the mount may break off.
For simplified installation, usually dowels for fastening are equipped with a special plastic gasket, which eliminates the possibility of a possible chipping.
At the next stage, the toilet is connected to the sewer, the tank is installed and the water is connected. When installing the tank, a rubber seal must be used. For greater probability, it can be smeared with silicone or other sealant. This will increase the quality of the docking and prevent water leakage during draining.
note
After filling the tank, it is necessary to drain it several times. This is done in order to make sure that all joints are completely sealed: between the tank and the toilet, on the water hose and on the connection of the sewer pipe.
At the end of all work, it is recommended to process the junction of the toilet bowl and the tiles on the floor silicone sealant. This will prevent water leakage and dampness accumulation.
On glue
You can also fix the toilet with glue. This is especially necessary when there is underfloor heating technology. Can be used as an adhesive different materials such as epoxy, silicone and other sealants.
If epoxy adhesive is available, use it only if the floors are sufficiently smooth. The work process is as follows:
- First, the floor surface must be thoroughly cleaned of all kinds of contaminants. Also, there should be no moisture that will interfere with good adhesion.
- To ensure a high adhesion quality, the floor tiles can be roughened with a stiff brush.
- Next, the surface is degreased with acetone or another solvent.
- If the glue is ready, then it must be applied to the bottom of the toilet bowl, with a layer thickness of up to 4 mm.
- Then bring the device to the sewer hole, dock and at the same time install it in its place.
- Putting the toilet on the floor, it must be pressed and left for half a day for the glue to harden.
- Only when the glue has dried, you can connect the tank and water supply.
That's the whole technology of gluing the toilet bowl to the floor.
On taffeta
If you have a wooden floor, then this method of fixing the toilet is the most suitable. Taffeta refers to a special lining made of wood.
The thickness of the wood should be around 300 mm. In order to prevent rotting of this embedded part, it must be treated with drying oil and other anti-corrosion compounds without fail. The essence of this technology is as follows:
- Stuff nails onto the prepared timber so that they peek out of the taffeta by 30 mm.
- Next, a recess is prepared in the screed according to the size of the taffeta.
- Fill the hole with mortar.
- Attach the workpiece to the solution with the side where the nails stick out.
- As a result, it should be flush with the floor.
- It is necessary to give time for the solution to fully seize and get stronger.
- After 12 hours, you can fix the toilet with self-tapping screws directly into the wooden mortgage.
Advice! To make the screws easy to tighten, they can be lubricated with graphite or grease. Thanks to this, after a while it will also be easy to unscrew them..
After that, the standard procedure for connecting the barrel is carried out. Additionally, you can smear the place where the toilet bowl joins the taffeta with silicone. This will eliminate the likelihood that moisture will flow under the sole and accumulate.
Conclusion
So, we looked at the two most common technologies for how to properly install a toilet on a tile. Also, in addition, we learned how to be if you have a wooden floor. As you can see, there are no particularly complicated processes. One of the main tasks is to choose the right fasteners.
Although in most cases, it comes with the purchased device. We hope that this material will help you deal with all the details of installing and fixing the toilet bowl on your own.
How to install a toilet on a tile with your own hands, video example
Installation of plumbing equipment is carried out in strict accordance with building regulations and norms. Home craftsmen often experience fear of such work. This is used by service companies that request very decent money for performing fairly simple operations. Meanwhile, fixing the toilet to the floor is quite affordable for self-fulfillment event. It is only important to carefully read the existing work technologies, choose the most suitable one, and follow all the instructions exactly.
Regardless of the chosen method of attaching the toilet bowl, installation work begins with the assembly of the cistern. The device is assembled in accordance with the instructions and fixed in place intended for it. Also, before installing the toilet, the units for supplying and discharging water must be prepared. There are several methods for attaching devices. The main selection criterion is the floor material on which the equipment will be installed. Let's take a closer look at the most common methods.
Method number 1: installation on dowels
The most practical method to install the device with least cost strength and time. It is optimal for use on a flat, smooth surface, since the slightest height difference adversely affects the quality of the flush. It is preferable to use this method of fastening for lightweight compact structures, since the fixation may not be entirely reliable. Plumbers advise installing equipment on a special gasket, which you can easily make yourself from old linoleum or a sheet of thin rubber. The toilet bowl is installed on the workpiece, circled around the contour with a marker. After that, with a sharp knife or just scissors, the gasket of the desired shape is cut out.
The device is fixed to the floor with dowels or special plumbing fasteners. Fasteners usually come with new equipment. It can also be purchased from specialized stores.
Now we need to markup. We “try on” the toilet bowl on the place prepared for the equipment and draw it around the contour. We remove the device. We apply a thin layer of sealant and glue the gasket on it. This design will be the most reliable, although some masters prefer to do without a substrate at all. You can start drilling holes for fasteners. As practice shows, if you glue the gasket with high quality and choose the diameter of the drill so that the holes for the fasteners are slightly larger than it, then further installation will be much easier. This is due to the fact that the rubber backing acts as a kind of "contact spot" for the floor and the device.
It happens that it is required not only to fix the toilet bowl to the floor, but also to raise it a little. This is true if there are several devices in the apartment. Then the last one in the system needs to be raised by about 3-4 cm. In this case, a piece of a two-inch board is used, which is used as a stand. It is cut exactly along the contour of the toilet and placed on the floor, a rubber substrate is placed on top of it. All this is fastened with a sealant and forms a reliable and solid construction. We drill holes for fasteners directly on the gasket.
Tighten the mount on the base of the toilet very carefully. Excessive force can damage the ceramics from which the device is made.
As fasteners, you can use long metal dowels or special plumbing fixtures. The latter usually come with new equipment. The quality of fixing they have is about the same, so you can use both options. We drive dowels into the holes prepared in the floor. We install the toilet and carefully screw it. It must be remembered that excessively strong tightening of the ceramic from which the device is made can be damaged.
Now you need to connect the device to the sewer. At this stage, we pay special attention to the corrugation. We generously lubricate both its edges with silicone. We insert one of them into the sewer socket, and put the second on the toilet outlet. All parts of the connection should be carefully pressed with your fingers so that the sealing is of high quality. As additional measure you can use metallized tape, which can be used to seal the joints. We connect the water supply and the device is ready for operation. There is a similar mounting method, which is presented in detail in the video.
Method number 2: mounting on glue
Of all the methods for fixing a toilet to the floor, this one is the easiest, but also the most time consuming. For the curing of the epoxy mixture, which is used as an adhesive, it takes about 12-15 hours. This method can only be used for smooth surface. Most often it is used to fix equipment on floor tiles. The method is very easy to perform. First, both surfaces to be bonded must be well cleaned of dust and debris. floor tiles can be sanded to make it rougher. This will improve the adhesion of the material. Surfaces are degreased with any solvent or acetone.
Preparing glue. You can buy ready-made epoxy or make your own. For this you need to take 100 parts epoxy resin ED-6, 200 parts of cement, 20 parts of solvent or plasticizer and 35 parts of hardener. The order in which the components are added to the solution is important. First, the resin is heated to 50C, a solvent is added to it, then a hardener, and at the very end - cement. The composition must be constantly stirred to form a plastic, homogeneous mass.
To keep the toilet securely in place, flooring prepared: cleaned for better adhesion and lubricated with a small layer of glue. Excess composition, speaking under the weight of the equipment, is immediately removed with a damp cloth.
Properly prepared adhesive mixture can be used within one and a half hours. We apply it to the base of the toilet bowl so that the solution covers an area of at least 20 square meters. cm, and the layer thickness was at least 4 mm. We install the prepared equipment in the right place, combining the sewer socket with the outlet, and press it to the floor with force. After that, the device is left for at least 12 hours. This period is necessary for the curing of the adhesive composition. During this time, it is not recommended to even touch the toilet. Then we connect the equipment to the water supply and sewerage.
Method number 3: taffeta mount
Most often, this method is used to install toilets on a wooden floor. Taffeta is a pad of durable wood to which equipment is attached. The thickness of the board from which the element is cut, corresponding to the shape of the toilet support rack, should be 28-32 mm. To protect the part from dampness, it must be carefully treated with drying oil. For reliable fixing to the floor from the bottom of the taffeta, an anchor is mounted. The simplest option is nails driven in a checkerboard pattern, which should protrude 2-3 cm from the part. The recess prepared for installing the toilet is poured cement mortar. Taffeta is sunk down into it with anchors. As a result, it should be flush with the floor.
After approximately 12 hours, during which the mortar is completely dry, you can proceed to fixing the equipment. The device is fixed with screws. Rubber washers must be placed under their heads, which will prevent possible damage to the toilet frame when tightened. Experts advise lubricating the screws with grease or graphite before work, so that later, if necessary, they can be easily unscrewed. Wood taffeta can be replaced with a rubber backing. It is cut from sheet material 5 to 15 mm thick, possibly even from an old rubber mat. Such a substrate should be 1-2 cm smaller than the toilet support column.
Mounting the toilet bowl on taffeta involves the use of a special wooden insert. The diagram shows all the elements of such a mount.
There are various ways to attach a standard toilet bowl to the floor. They differ significantly in complexity and time spent on installation work. It is important to choose the right fastening method. It depends on the material from which the floor is made in the room. Installation work can be carried out independently, but if there is no experience or desire, it is better to turn to professionals. They will quickly and competently carry out all the work, guaranteeing a long and flawless service of the new equipment.
Now there are three main ways of fixing the toilet bowl. They differ in fasteners (dowels, glue, screws), as well as the base or material from which the floor in the bathroom is made. The time that will pass from the moment the work is done to the start of using the toilet will also differ. We will try to consider these ways of attaching the toilet bowl and the nuances that are worth considering.
Ways to fix the toilet to the floor
Main ways:
- Dowel fastening.
- Adhesive installation.
- Installation with taffeta.
Even before buying, you must also decide how to fix the toilet to the floor. Let's consider these methods.
Dowel fastening
This mounting method is the most common. The basis for this fastening is a concrete floor. Also, the floor can be tiled, amenable to drilling.
The underlying surface must be level enough so that the toilet can be mounted without distortion, and in the future the drain system will work normally.
How to properly install and fix the toilet
Before proceeding with the installation, you need to make sure that the connecting link between the toilet bowl and the sewer pipes allows you to mount it in the right place. If a flexible corrugation is used, there will be no problems. If a rigid pipe or elbow is used, then it is necessary to first put them in the working position, and, if necessary, adjust them to size, cutting off the excess. This adjustment is carried out with any method of fastening.
When buying, make sure that bolts for fixing the toilet bowl are included with it. Otherwise, you need to purchase the kit yourself.
Check that the diameter of the dowels and bolts matches the hole in the base of the toilet. The bolts must be provided with a rubber gasket under its head.
To secure the toilet tiled floor, it is installed in the required position and mark future holes. The toilet bowl is removed, then with a drill in the normal drilling mode, holes are drilled with a diameter indicated on the dowel to a depth of at least the length of the dowel .
It is necessary to drill holes in concrete (not in tiles) at a slight angle with the drill moving inward, since the shelf on the toilet leg, for which it will be attracted, also has a certain slope.
- Drilling tiles. For drilling tiles, drills with special soldering for tiles are used. Do not use drills for an impact drill or hammer drill. After the tile has been drilled, concrete drilling can be continued in the hammer drill mode with a concrete drill bit. If the drilling depth is large, it is necessary to allow the drill to cool down.
- Drilling porcelain stoneware. For drilling porcelain tiles, use porcelain stoneware bits. Because small diameter bits do not have a center drill, a jig is used to hold the bit in place. It is made from a piece of board by drilling holes in it with a diameter corresponding to the crown. The conductor is placed over the marked hole, a drill with a crown is inserted and a small recess is drilled. After that, the conductor is no longer needed.
- Cooling of the crown is carried out by pouring a small amount of water directly onto the drilled recess and around the future hole.
When the holes are ready, dowels are inserted into them, a toilet bowl is placed on top and bolted to the floor.
Some experts advise using a rubber gasket between the tile and the toilet. It will serve as a kind of damper, which will ensure a more uniform fit of the toilet bowl to the tile and close possible gaps. This gasket must be cut exactly to the shape of the mounting surface.
Clear sealant can also be used to seal gaps. It is pre-applied to the bottom of the toilet, or they pass along the bypass after installation.
To avoid damage ceramic coating on the toilet, under the head of the bolt it is necessary to place a rubber gasket with a diameter of at least the head. Also, the bolt should be screwed tightly, but without undue force. It's ceramic, not metal, it's brittle.
Now it remains (if necessary) to ensure the tightness of the outlet element at the junction with the toilet and the reception sewer pipe ferrules, connect the water supply, adjust the drain and the product can be used.
How to fix a toilet with side holes
This is a variation of the first method. However, the side mounting of the toilet to the floor is different. The fasteners themselves will be located inside the installation leg of the toilet bowl. For them, holes are also marked on the floor, and fasteners are first screwed. Then a toilet bowl is installed on top of them and fixed to the fixtures through the side holes. This type of fastening is a little more complicated, but has a more aesthetic appearance.
If the toilet is installed before laying the tiles (which is undesirable), then it is necessary to provide a substrate on which it will be raised to the future floor level. Subsequently, this will facilitate the maintenance and replacement of the toilet bowl without damaging the floor covering.
Adhesive toilet installation
When it is unacceptable to drill the floor at the installation site of the toilet, then the only method of fastening will be mounting on an adhesive basis. If you have been thinking about how to fix the toilet so that it does not stagger, then this method will probably be the most suitable.
Start by cleaning the floor and base of the toilet from dust, dirt, grease and other substances that prevent adhesion. After that, the toilet bowl is installed in its future place and its shape is outlined with a marker.
The tile at the place of gluing must first be treated with a rough sandpaper or other tool for roughening the surface. This will significantly enhance the adhesion (sticking) of the adhesive to the tile.
After that, dust is removed from the surfaces to be glued, and they are degreased with a solvent or acetone. A layer of special epoxy-based adhesive is applied along the line circled on the floor. The thickness of the adhesive must be at least four millimeters. In order not to bother yourself with cooking, it will be much easier to buy it cooked.
On top of the glue applied, we carefully install the toilet bowl, combining the outlet of the toilet bowl with the sewer pipe. We press the toilet bowl, leveling the surface for sitting.
Now it must be left alone for at least 12 hours until the adhesive hardens. At this time, it is advisable not to even touch it. After curing, the necessary connections are established.
The toilet is ready for use.
Mounting with taffeta
If your bathroom has wooden floors and the boards are thin, you need to think about how to secure the toilet so it doesn't wobble.
This problem is designed to solve the methods of fastening the toilet with taffeta. These methods involve the creation of a certain void in the floor in the form of the installation surface of the toilet bowl with a recess of 5–7 centimeters. It will be filled with cement mortar to a depth of floor level minus the thickness of the taffeta.
Taffeta is made from hard rock wood (oak, acacia). A board with a thickness of 28 - 32 millimeters is taken, a shape is cut out of it, corresponding to the shape of the toilet sole. This form must be plentifully processed with drying oil to avoid getting wet and swelling. From the bottom of this form, nails or anchors are stuffed in a checkerboard pattern. They should protrude beyond the board by 2 - 3 centimeters.
We make mortar or concrete mix. Depending on the required thickness solution should choose its strength. For a thickness of 3 - 5 centimeters, a proportion of cement grade 400 to sand 1/4 will be sufficient. With an increase in the thickness of the solution, its strength should decrease, and the number of stuffed nails should increase.
If possible, it is better to prepare a concrete mix on crushed stone of fraction 5 - 10 with volume proportions of cement / sand / crushed stone - 1/3/3. The result is a sanded concrete that will not crack with a large layer thickness, but will be mobile enough to bury the taffeta into it.
Then the taffeta is immersed in the solution, poured into the recess, and with vibrating movements is lowered to the same level with the floor. Excess solution should then spread to the sides. If this is not possible, it is necessary to provide for the possibility of removing excess solution. To do this, the recess in the floor should be slightly wider than the taffeta, and the mortar should have sufficient plasticity. This is achieved by adding a plasticizer, but not water.
Now you need to let the solution set. Although it is advised to wait 12 hours, it is desirable to increase this time if no reaction accelerators have been added to the solution. Wait at least a day. After all, the time for the complete reaction of cement without additives is 28 days.
After setting the solution, you can install the toilet. It is fixed with long screws of the appropriate diameter. Don't forget to put rubber pads under the screw heads.
