Do-it-yourself stove from an old bath. How to make a stove from an old cast-iron bath with your own hands. How to cut a cast iron bath

What just do not come up with to build with their own hands craftsmen from improvised means. If you have an old one, which is usually adapted for watering the garden, and the construction of a bath is brewing, then you can save a lot by making a stove in the steam room from this bath. We will tell you how to make such an oven step by step with photos and videos.

Advantages of cast iron

oven from cast iron bath will be practically eternal. Even enamel will not burn quickly. In Soviet times, enamel was applied in two layers. The enamel contained quartz sand. After enamel coating, the product was baked in an oven at a temperature of more than 800 degrees. The sand melted, and such a coating served for decades. The only way to damage the enamel with a strong blow from a heavy object.

A cast iron tub is strong enough to be used as a stove.

In addition, cast iron has a high heat capacity, well accumulates and gives off heat. Not afraid of corrosion. The industry produces furnaces and grates made of cast iron, as it does not burn out for a long time, unlike steel. But cast iron is a fairly brittle metal.

Bath cut

Sawing a bath is best on the street, after turning it upside down. Cast iron is a brittle metal, so the procedure requires accuracy. The cut is done by a grinder. Buy several at once cutting discs. We make markings, and then slightly incise the enamel along the line so that chips do not form with a full cut. We saw through cast iron at a slight angle and make sure that the tool does not heat up. We take breaks. To prevent the halves of the sawn tub from pinching the disc at the final stage of cutting, place supports made of wood or brick along the edges of the cut.

Foundation for the furnace

The type of foundation depends on the total weight of the furnace:

a brick base is suitable for a light oven. Bricks are laid on edge and bound with mortar. Grade of cement for binder solution is not less than M300;
for a heavy furnace weighing more than 700 kg, a self-leveling foundation with a depth of at least 50 cm is required. Formwork is made and poured with liquid concrete with or without filler. The filler will be a broken brick of fine fraction or gravel.

It is possible to build a furnace only on a solid and heat-resistant foundation.

The top of the base is arranged flush with the floor or 15 cm below the floor level. To protect the base from moisture, the bottom and walls of the formwork are lined with roofing material and all joints are coated with bitumen.

Advice. The base should protrude beyond the boundaries of the furnace by 50 cm. In front of the combustion chamber, 1.2 m of space should remain free.

Furnace No. 1

This version of the furnace is able to warm up a bath of 7 square meters. m to 80 degrees in just a couple of hours. To build a furnace, you will need scrap metal: a cast-iron bath, a gas cylinder and a metal drum from a 40 cm diameter conveyor belt. The drum can be replaced gas cylinder or a pipe - this will be the combustion chamber. The sequence of work is as follows:

Advice. If a flat metal platform is welded to the cylinder, you get a stove for heating the kettle.

Furnace No. 2

From a cast-iron bath sawn into two parts, you can make a combustion chamber for sauna stove. You will need one half, the second can be used for a fireplace.

The remaining half can be used to build a fireplace. Cast iron will easily withstand brickwork if you veneer the fireplace with an arched vault. And for this you do not need to make complex pattern from plywood. The front part is made out by a portal. The chimney is removed. You can make the fireplace closed by installing a transparent door on the firebox and admire the flame.

Advice. Cast iron and red ceramic bricks have different coefficients of thermal expansion. Therefore, when building brick walls provide for expansion joints that are filled with asbestos or refractory cardboard made of basalt.

Furnace No. 3

The third version of the stove is often used as a garden barbecue and for cooking in the summer. If the upper chamber is filled with stones, then this design will replace the traditional stove in a small bath, so we will not bypass this model.

Such non-standard designs are easy to manufacture and require minimal financial costs. A thing that has served its purpose will receive a second life, and you will receive a convenient and practical stove that will serve you faithfully for many years.

There comes a time when plumbing, due to its appearance or malfunction, becomes unusable. But, replacing it with a new one, you should not rush to throw it away. Summer residents and home owners can easily make a garden stove from a cast-iron bath, which will not be inferior to factory models in terms of strength and service life.

Advantages of using cast iron

This type of metal is rightfully considered one of the best furnace materials. Its main advantages include:

environmental safety. When heated, it does not emit harmful substances.
Temperature resistance. An outdoor stove made of bricks can begin to crumble after a few years.
High thermal conductivity. A cast iron fireplace warms up a room much faster than one built from other materials.
Strength . Cast iron is the leader among metals in terms of strength. Even steel ovens are less reliable.
Ease of use.
fire safety.

The disadvantages of cast iron that you should pay attention to are brittleness and susceptibility to corrosion. In the first case, unnecessary mechanical influences should be avoided, in the second case, the surface should be treated with special solutions.

A home-made cast iron structure will not turn out very beautiful, so it is recommended to overlay it with brick or stone.

Preparation of materials and tools

To create such a miracle oven from the bath, you need to prepare:

angle grinder (grinder);
2-3 circles for metal with a thickness of at least 1 mm, a diameter of 12.5 cm;
electric drill;
drills for metal with a diameter of 9, 11 mm;
grinding wheels;
files;
hammer;
level;
construction gun (for applying sealant);
plumb;
putty knife;
Master OK.

Materials you will need:

iron or steel sheet 5 mm;
refractory red brick;
grate;
sealant;
clay;
sand;
metal corner;
bolts with nuts, washers;
chimney pipe with a diameter of 12 cm.

When all the materials, tools are collected, you can start cutting the container. For convenience, it can be turned upside down or laid on its side.

Users often search:

You need to wield the grinder carefully so as not to damage the surface.

Before you start sawing the bath, it is worth considering a few nuances:

Marking will simplify cutting the product.
The first layer of enamel is removed strictly along the drawn line. This will help prevent chipping at the edges.
The next step is to cut the cast iron. Do this gradually, in small pieces of about 10 cm, so as not to overheat the grinder.
When the bath is already sawn in half, supports are placed under each part. They will not allow parts to fall and damage the tool, material.

According to reviews experienced builders, grinder better to work at an angle. So the enamel does not start to peel off and all the cuts will turn out to be smooth without burrs.

Subject to the use of a high-quality grinder, the processing of cast iron will take no more than 1 hour.

For a barbecue, you will need two halves of the bath: one part will serve as a fuel loading chamber, the other is necessary for cooking. For a sauna stove or fireplace, one half will be enough.

Step-by-step creation of a furnace from a bath

Without building experience, it is worth consulting with a specialist about all the intricacies of masonry and installation of parts, but it is better to perform work under the supervision of a master. So the product will turn out to be of high quality and standards fire safety will be observed.

As for the construction of the foundation, its type depends on the total weight of the furnace:

For structures over 700 kg, a monolithic or strip base with a depth of 50 cm or more should be equipped. A formwork is constructed along the perimeter of the pit and covered with a layer of crushed stone or broken brick. Compacted. Filled with concrete.
For ovens small sizes enough brick foundation. It is recommended to purchase cement grade not lower than M300. Bricks are placed with an edge, fastened together with a solution.

Now consider detailed instructions for the manufacture of each of the furnaces with different purposes.

For a bath

To create in the steam room the necessary conditions, the design must meet the following requirements:

have a high thermal power;
regulate convection currents;
produce enough steam.

The procedure for building a sauna stove:

It is important to note that the foundation must have a protrusion on the borders of the furnace of at least 50 cm, and 1–1.5 m of free space must be left in front of the furnace.

An interesting idea is to make a bath stove from both halves of the bath. The second part will be needed as an extension for heating water, or you can lay out a Russian heater from it.

For cooking

On suburban area not to do without a barbecue or a brazier. And the opportunity to bake delicious bread, fry meat in the fresh air makes the owners equip small outdoor ovens on the territory.

Here is a description of how to build a barbecue step by step from the bath.

The sequence of work is as follows:

Some masters leave the barbecue in this state, but in order for your oven to look beautiful, you still need to do exterior finish.

There are several options:

Clay whitewashing.
Whole masonry ceramic tiles or pieces of it.
Surface finish natural stone pre-cut into pieces 10 mm thick.

The materials are attached to the furnace with heat-resistant adhesives.

A good solution is to install the chimney to the furnace through the drain hole of the bath, expanding it in advance, and only then weld it to the steel sheet.

For heating

In the country, it is easy to build a fireplace from half a bath. He can be:

Built into the wall. Suitable if the house has brick walls. Significantly saves free space.
Reclined (half-open). The firebox is located at a considerable distance from the wall. This fireplace does not need a separate foundation, it is mounted directly into the floor. Has good draft, the built-in ashpit.

The advantage of using a cast-iron bath for the furnace part is that the fireplace is obtained in the form of an arch and eliminates complex brickwork. The hole for the chimney is made at the top of the tub. The outer part is decorated with a fireplace portal.

When building a semi-open fireplace, the following recommendations should be taken into account:

Pour under the base cement mortar up to 15 mm thick.
A metal mesh is laid on top.
A layer of waterproofing is applied.
Asbestos cardboard type insulation is laid.
A pedestal under the firebox is being built. Suitable brick, aerated concrete. The binder mixture is cement mortar or heat-resistant glue.
The structure is plastered. You can finish it with stone, ceramic tiles.
Between the lining and the fireplace insert, a gap is left for the convection heating system.
The chimney pipe is mounted in the hole made, removed through the ceiling, the roof. Often made in the form of a sleeve.
From the inside of the firebox, the chimney is sheathed with heat-insulating non-combustible material.
Finishing the bottom of the fireplace.
The product is closed from the side and from above with a frame made of duralumin corners connected by self-tapping screws.
The frame is sheathed with drywall.
Holes are made in the lining for air ventilation.

When installing a chimney, it is important to take into account that with a pipe height of up to 5 m, the deviation angle is 45 0, over 5 m - no more than 20 0.

For waste disposal

An unusual decision to build from old bath waste incinerator.

The principle of its construction is similar to a street barbecue.

Scheme of placement of the furnace on a brick base

The alternative is to remake the old heater by removing all parts except for the grate and body. Part of the cast iron is welded to the base from the inside to strengthen the structure.

In such a fiery trash can, you can load waste directly from above. When burning, the stove should be covered with another part of the bath so that the smoke does not disperse throughout the area.

So do not rush to get rid of things that are out of order or have lost their appearance. IN skillful hands even an old bath will get a second life, it will become a functional stove that will last for many years.

If somewhere in the garage or in the country an old cast-iron bath is lying around, you should not rush to hand it over for scrap. From it you can make an excellent outdoor oven and install in the garden.

The stove will become from an old unnecessary thing decoration and great helper, delighting guests and households with delicious and original dishes.

Most often from old cast-iron baths they make garden barbecue oven. Cast iron, from which the bath is made, has a high thermal conductivity, keeps warm for a long time and allows you to cook not only the usual food, but even bake bread and other unique dishes.

How to make a stove out of an old cast-iron bath?

The essence of the construction is that the bath cut in half. The resulting halves are placed one on top of the other, with the curved side outward and laid metal sheet between them.

It separates the firebox and the chamber in which the dishes will be prepared. Holes are made in the iron sheet and the upper half of the bath for chimney and the pipe is welded.

It remains to strengthen the structure, to give it interesting view, insert grate and do doors.

Necessary materials and inventory

To build a garden stove you will need:

herself bath, it can be steel, but better - cast iron;
Bulgarian;
edged metal cutting wheels;
circles for grinding;
Metal sheet thick 5 mm and more;
drill;
bolts;

heat resistant sealant;
tape measure or roulette;
pencil or marker;
welding machine ;
pipe for the chimney;
grate;
bricks;
clay;
sand.

Preparatory work

Before embarking on the construction of a structure, you need make all the pieces:

Mark the middle of the bath and cut it in half - this work is laborious and dusty, so better to spend it outside by turning the tub upside down.
Cut a blank from a metal sheet according to the size of the resulting halves.
On a cut sheet of iron and half of the bath, which will be on top, mark holes for the chimney and cut them out.
weld pipe into the partition and bring it out through the top.
Do markings for fasteners.

Important! All work on sawing, grinding edges and trimming the iron sheet must be carried out wearing goggles. A welding work- V special mask.

Building a stove with your own hands

When all preliminary the work is done, you can proceed directly to the construction of the furnace itself.

Foundation

Furnace design pretty heavy, so you can't do without a foundation. It will not allow the device to shrink and deform.

For a structure that is not heavy in weight, the foundation can be brick. For more weighty is done bulk- depth up to 50 cm. In order for the furnace to be at a convenient level, supports of the desired height are concreted into the foundation.

Further work is being carried out after complete drying foundation.

In the lower part - the combustion chamber - is installed grate.

Photo 3. The oven, assembled from two halves of the bath, is almost ready. It remains to attach the doors.

If the design of the furnace provides for a firebox and a blower closed with brickwork, then during operation immediately doors are mounted: for the blower in the lower part, for the firebox - a little higher, opposite the grate.

Important! The damper or door handle must be wooden to avoid burns.

The wall is laid out to the junction of the edges of the bath with each other. Bricks should fit snugly against all edges of the oven.

For top compartment stoves are provided shutter or doors. In a tightly closed part, you can not only cook any dishes, but even bake bread.

Insulation of the cooking chamber

Upper half drags on chain-link mesh, throws 1 part clay to 2 parts sand, thickness up to 7 cm and aligns. Can decorate the top wild stone, pieces heat resistant tiles or simply whitewash.

The final stage

That's it - oven ready, you can already use it. But many try to give it more modern look why rough work is hidden beautiful brickwork, veneer wild stone or decorative tiles.

Possible difficulties during work

Problems during the construction of a garden stove, there may be on preparatory stage when cutting through an old cast-iron tub.

Advice. Work is carried out with glasses and tight clothes covering the body.

Need to cut it carefully, don't rush. First, a layer of enamel is cut along the marking line to prevent chipping. Then the cast iron is cut at an angle, making small cuts, and not allowing the grinder to overheat. To prevent the disk from being pinched by the tub halves, the incision site is bursting wooden stick or brick.

A do-it-yourself oven from an old cast-iron bathtub opens up endless possibilities for every craftsman who loves to craft with his own hands.

Collapse

Due to the regular obsolescence of cast iron baths, their cost decreases from year to year, and the benefits in the construction of the furnace cannot be measured by any money.

Forget that your own oven is expensive. All it takes is a small set of tools and some personal time.

Construction device

The most commonly used cast-iron bath of the classical type, which is divided into two equal parts. From above, the free plane is closed with a steel sheet to create a closed space.

A concrete floor or brickwork can be used as a base. With a properly made cut, open cracks will not appear that will interfere with traction.

The chimney itself is connected at the outlet of the drain, which avoids the need to perform a number of additional cuts and drillings. It should be understood that a bath stove cut in half can be additionally sold or donated to close friends, since two stoves can be created from one bath.

Conclusion

It's not hard to make your own cast iron bath stove. Follow the instructions carefully for fantastic results. Be sure that the quality of the oven will not be inferior to industrial models, but the cost will be orders of magnitude lower than that of the original!
