How to make a stove from a cast iron bath. Garden stove from a bathtub Stove from a bathtub for a bath

What folk craftsmen can come up with to build with their own hands using improvised materials. If you have an old one, which is usually adapted for watering the garden, and the construction of a bathhouse is brewing, then you can save a lot by making a stove into a steam room from this bathtub. We will tell you how to make such a stove step by step with photos and videos.

Advantages of cast iron

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

Cast iron bathtub is durable enough to make a stove out of it

In addition, cast iron has a high heat capacity, accumulates and releases heat well. Not afraid of corrosion. The industry produces fireboxes and grates from cast iron, since it does not burn out for a long time, unlike steel. But cast iron is a rather brittle metal.

Cutting the bathtub

It is best to saw the bathtub outdoors, after turning it upside down. Cast iron is a brittle metal, so the procedure requires care. The cutting is done with a grinder. Buy several cutting discs at once. We make markings, and then lightly cut the enamel along the line so that when a full cut is made, chips do not form. We saw through the 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 disk at the final stage of cutting, place supports made of wood or brick along the edges of the cut.

Furnace foundation

The type of foundation depends on total weight ovens:

For light stove A brick base is suitable. The bricks are laid on edge and bonded with mortar. Cement grade for binder mortar 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 will be required. Formwork is made and filled with liquid concrete with or without filler. The filler will be fine broken brick or crushed stone.

The stove can only be built on a solid and heat-resistant foundation.

The top of the base is placed 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 covered with roofing felt and all joints are coated with bitumen.

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

Furnace No. 1

This version of the stove is capable of heating a bathhouse of 7 square meters. m to 80 degrees in just a couple of hours. To build a stove you will need scrap metal: a cast iron bath, a gas cylinder and a metal drum from a conveyor belt with a diameter of 40 cm. 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 you weld a flat metal platform to the cylinder, you will 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 the fireplace.

The remaining half can be used to build a fireplace. Cast iron can easily withstand brickwork, if you line the fireplace with an arched vault. Moreover, for this you do not need to make a complex template from plywood. The front part is decorated with a portal. The chimney is removed. You can make the fireplace closed by installing a transparent door on the firebox and admire the flames.

Advice. Cast iron and red ceramic brick has a different coefficient of thermal expansion. Therefore, when constructing brick walls provide expansion joints, which are filled with asbestos or fire-resistant basalt cardboard.

Furnace No. 3

The third version of the stove is often used as a garden barbecue and for cooking in summer time. If the upper chamber is filled with stones, then this design will replace a traditional oven in small sauna, so let’s not ignore this model.

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

How to make a stove from a cast iron bathtub

The bath needs to be divided in half. The halves are connected to each other with the concave part facing outwards. Between the separated halves lies a sheet of metal with a thickness of 10 mm, which separates the firebox from the place where the food will be cooked. Through holes are made in the upper cut-off part of the bath and a sheet of metal for the pipe, which in turn will serve as a smoke exhaust, and the pipe is welded. Then they fix the stove and give it an aesthetic appearance.

Tools and material for manufacturing

To make it you will need:

unnecessary cast iron bathtub
a metal sheet
grinder with metal disc
heat resistant sealant
pipe, drill, bolts
welding

Preparatory work

First you need to make blanks:

the bath is marked in the middle, turned upside down and divided in half
cut a blank from a metal sheet to the size of the resulting half of the bath
Mark and cut through holes for the pipe on the sheet of metal and the top of the bathtub
the pipe is welded and brought out through the upper part
make markings to fasten the halves of the bathtub and the sheet between them

Foundation for a stove made of a cast iron bath

Since our oven will be heavy, we need to make under it. With a foundation, the stove will not shrink or become deformed. It can be made brick or for too large design liquid Supports are embedded into it at the required height so that the stove is at the same level.

Assembling a stove from a cast iron bath

The edges of the combustion part are coated with heat-resistant sealant, then an iron sheet with a welded chimney is placed on it.

The parts of the bathtub with an iron sheet in the middle are pressed together with bolts.

The entire structure is fixed on supports. Then it is covered with bricks. A grate is inserted into the combustion part.

If the stove has a closed firebox, then the doors are immediately installed during the manufacturing process of the stove.

Furnace insulation

The upper part of the furnace is pulled together metal mesh and covered with clay and sand. Then lays out decorative rock or heat-resistant tiles. If it’s easier, you can just whitewash it.

Problems in kiln construction

Problems during the construction of a barbecue oven can occur during the preparation stage during work related to cutting the bathtub. It must be divided very slowly, without haste. First you need to cut the enamel layer in order to avoid chipping. Then they begin to saw the metal at an angle, making small cuts. The grinder should not overheat. To prevent the bath halves from pinching the disk, the cut must be spread with a suitable board or fittings.

Cast iron is an ideal material for building a stove from a bathtub with your own hands in your garden for preparing various dishes. But since cast iron can only be processed in industrial conditions, to make something from it with your own hands you should use ready-made cast iron products, for example, an old bathtub.

Advantages of cast iron:

resistant to high temperatures;
has a high heat capacity;
not subject to corrosion.

Making a stove from a cast iron bath is quite difficult, this process requires attention and patience, since the bath itself is strong, but has a fragile structure.

Making from an old bathtub

A stove of this type is two interconnected halves of an old bathtub, located on top of each other. Therefore, you will first have to cut the bathtub in half.

Attention! Before you begin, remember that cast iron is a very fragile material, and any, even minor damage, can ruin it and make further processing impossible.

To divide the bathtub into two equal parts, it is best to use a grinder, drawing a cutting line in advance and accurately measuring the distance to the edges. Only after this can you carefully begin cutting the bathtub. Stock up on several cutting discs, as one may not be enough.

The most important thing to remember is: take your time. If you want to achieve an even and smooth cut edge, there is no need to rush anywhere.

Main stage: installation of the furnace

Most reliable way fix the stove and give it stability - . It must be massive enough to ensure the immobility of the entire structure.

After fixing the lower part of the furnace, a sheet of steel about 6-10 mm thick is placed on it.

But keep in mind that the speed at which the oven warms up will depend on its thickness. It will serve as a separation between the firebox and the oven, as well as the hob. You also need to make a hole in it for the chimney, which will be welded to it later.

There comes a time when plumbing fixtures, due to their type or malfunction, become unusable. But, having replaced 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 bathtub, which in terms of strength and service life will not be inferior to factory models.

Advantages of using cast iron

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

Environmental safety. When heated, it does not emit harmful substances.
Resistance to temperature changes. An outdoor stove made of brick may begin to crumble after just a few years.
High thermal conductivity. A fireplace made of cast iron will warm up a room much faster than one built from other materials.
Durability. Cast iron is the leader among metals in terms of strength. Even steel furnaces less reliable.
Ease of use.
Fire safety.

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

A homemade cast iron structure will not turn out very beautiful, so it is recommended to cover it with brick or stone.

Preparation of materials and tools

To create such a miracle stove from a bathtub, you need to prepare:

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

Materials you will need:

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

When all the materials and tools have been collected, you can start cutting the container. For convenience, you can turn it upside down or lay it on its side.

Users often search:

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

Before you start sawing the bathtub, there are several nuances to consider:

Marking will make cutting the product easier.
The first layer of enamel is removed strictly along the drawn line. This will help prevent chipping along 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 bathtub has already been cut in half, supports are placed under each part. They will prevent parts from falling and damaging the tool or material.

According to reviews experienced builders, grinder It's better to work at an angle. This way the enamel will not begin to peel off and all cuts will turn out smooth without burrs.

If you use a high-quality grinder, processing 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 stove from a bathtub

Without construction experience, it is worth consulting with a specialist about all the intricacies of masonry and installation of parts, and it is better to carry out the work under the supervision of a foreman. This way the product will be of high quality and standard. fire safety will be respected.

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

For a structure over 700 kg, a monolithic or strip base with a depth of 50 cm should be installed. Formwork is constructed around the perimeter of the pit and covered with a layer of crushed stone or broken brick. It gets compacted. Filled with concrete.
For furnaces small sizes A brick foundation will suffice. It is recommended to purchase cement grade no lower than M300. The bricks are placed edgewise and fastened together with mortar.

Now let's consider detailed instructions for the manufacture of each of the furnaces for different purposes.

For the bath

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

have high thermal power;
regulate convection currents;
produce sufficient steam.

The procedure for constructing a sauna stove:

It is important to note that the foundation must have a protrusion towards 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 firebox.

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

For cooking

You can’t do without a barbecue or grill at your summer cottage. And the opportunity to bake delicious bread, fry meat on fresh air forcing owners to install small outdoor stoves on their property.

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

The sequence of work is as follows:

Some craftsmen leave the barbecue in this condition, but in order for your stove to look beautiful, you should still do exterior finishing.

There are several options:

Whitewashing the clay part.
Whole masonry ceramic tiles or pieces of it.
Surface finishing natural stone, pre-cut into pieces 10 mm thick.

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

A good solution is to install a chimney to the stove through the bathtub drain hole, widening it in advance, and only then weld it to a steel sheet.

For heating

At the dacha it is easy to build a fireplace from half a bathtub. He can be:

Built into the wall. Suitable if the house has brick walls. Significantly saves free space.
Leaned (half open). The firebox is located at a considerable distance from the wall. This fireplace does not require a separate foundation; it is mounted directly into the floor. It has good traction and a built-in ash pan.

The advantage of using a cast iron bath for the combustion part is that the fireplace is shaped like an arch and eliminates complex brickwork. The hole for the chimney pipe is made at the top of the bathtub. The outer part is decorated with a fireplace portal.

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

Poured under the base cement mortar up to 15 mm thick.
A metal mesh is laid on top.
A layer of waterproofing is applied.
Insulation such as asbestos cardboard is laid.
A pedestal for the firebox is being built. Brick or aerated concrete will do. The binder mixture is cement mortar or heat-resistant glue.
The structure is plastered. You can decorate it with stone or ceramic tiles.
A gap is left between the lining and the firebox for the convection heating system.
The chimney pipe is mounted in the hole made and discharged through the ceilings and roof. Often done in the shape of a sleeve.
The inside of the firebox and chimney are lined with heat-insulating, non-combustible material.
The lower part of the fireplace is being finished.
The product is closed from the side and top with a frame made of duralumin corners connected with self-tapping screws.
The frame is covered with plasterboard.
Holes are made in the cladding 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 deflection angle is 45 0, over 5 m - no more than 20 0.

For waste disposal

An unusual solution to build a waste incinerator from an old bathtub.

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

Layout of the stove on a brick base

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

You can load waste into this fire bin directly from the top. When burning, the stove should be covered with another part of the bath so that the smoke does not disperse throughout the entire area.

So don’t rush to get rid of things that are out of order or out of shape. Even in capable hands old bath will get a second life and become a functional stove that will last for many years.
