You won't believe what can be made from an old cast-iron bathtub - a stove, barbecue and other unusual things. Do-it-yourself sauna stove made from a cast-iron bathtub Stove made from a cast-iron bathtub

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 cast iron bath, 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:

1. Environmental safety. Doesn't emit when heated harmful substances.
2. Resistance to temperature changes. An outdoor stove made of brick may begin to crumble after just a few years.
3. High thermal conductivity. A fireplace made of cast iron will warm up a room much faster than one built from other materials.
4. Durability. Cast iron is the leader among metals in terms of strength. Even steel stoves are less reliable.
5. Ease of use.
6. 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:

• corner grinding machine(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:

1. Marking will make cutting the product easier.
2. The first layer of enamel is removed strictly along the drawn line. This will help prevent chipping along the edges.
3. 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.
4. 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, it is better to work with a grinding machine at an angle. This way the enamel will not begin to peel off and all cuts will be 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

Not having 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 specialist. 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 total weight ovens:

• 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 bricks. 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

On summer cottage You can’t do without a barbecue or grill. 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:

1. Whitewashing the clay part.
2. Whole masonry ceramic tiles or pieces of it.
3. 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 need separate foundation, it is mounted directly into the floor. It has good traction, built-in ash pan.

The advantage of using a cast iron bath for the combustion part is that the fireplace is in the shape of an arch and eliminates the complexity 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:

1. Cement mortar up to 15 mm thick is poured under the base.
2. A metal mesh is laid on top.
3. A layer of waterproofing is applied.
4. Insulation such as asbestos cardboard is laid.
5. A pedestal for the firebox is being built. Brick or aerated concrete will do. The binder mixture is cement mortar or heat-resistant glue.
6. The structure is plastered. You can decorate it with stone or ceramic tiles.
7. A gap is left between the lining and the firebox for the convection heating system.
8. The chimney pipe is mounted in the hole made and discharged through the ceilings and roof. Often done in the shape of a sleeve.
9. The inside of the firebox and chimney are lined with heat-insulating, non-combustible material.
10. The lower part of the fireplace is being finished.
11. The product is closed on the side and top with a frame made of aluminum corners connected with self-tapping screws.
12. The frame is covered with plasterboard.
13. 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 from old bath waste incinerator.

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. In skillful hands, even an old bathtub will get a second life and become a functional stove that will last for many years.

Dachas purchased back in Soviet times are real treasure troves: in the attic, in the utility room or right on the street you can find many rare or simply useful things for the household. For example, an old cast-iron bathtub, discarded as unnecessary, most often plays the boring role of a container for watering plants. It will bring much more benefit if, with the help of skillful hands, it turns into a heat source or cooking unit. We offer detailed description How to make your own oven from a bathtub, in which you can stew meat and bake pies.

Cast iron parts are valued in manufacturing heating devices for two reasons:

• the metal heats up quickly and retains heat for a long time;
• Despite sudden temperature changes, cast iron does not wear out and lasts for decades.

Even the enamel used to cover plumbing equipment, retains its qualities and does not burn out immediately. The fact is that the technology of applying a layer of enamel in the last century involved heating finished product up to 800ºС. The quartz sand included in the solution melted under the influence of high temperature and contributed to the baking of the enamel. She received high performance strength and at the same time “welded” to cast iron. The only thing you should be wary of is sharp, heavy impacts, which can cause cracks.

An old cast iron bathtub is the main element of a garden stove

The concave shape of the product is also suitable for constructing a fryer. It resembles a dome, which can also serve as a base oven, and the combustion chamber compartment. So, if you want to build an original barbecue oven with your own hands from an old bathtub, arm yourself with the tools and get to work.

Preparing tools

You will need tools for metal processing and masonry construction. To cut a cast iron bathtub, sand its edges, and make holes for fasteners, you will need:

• laser level, plumb line, tape measure, marker - for marking;
• grinder with a set of circles (for cutting metal - 125 mm in diameter and 1 mm thick, for grinding);
• files with coarse and fine notches, sandpaper;
• electric drill, drills 9-11 mm;

• hammer, pliers, metal cutters.

In addition to metal parts, there will be brickwork at the base of the structure, so a mixing attachment will be required cement mortar, container for it, trowel, spatula.

If you do not use an angle grinder all the time, you can rent it

List of required materials

Several items made of cast iron (if not, then stainless steel will do):

• cast iron bathtub “old school”;
• grate;
• stove with burners or metal sheet (5 mm or thicker);
• door (beautiful forged or just standard).

More from metal elements you need corners for fixing the grate, fastening bolts with nuts, a chain-link mesh to strengthen the clay layer, a pipe for making a chimney (diameter from 100 mm to 120 mm).

The masonry is made of refractory bricks, fastening the rows with clay-sand mortar. The amount of brick depends on the size of the structure. If planned exterior finishing ceramic devices, you should purchase tiles and heat-resistant adhesive, as well as heat-resistant sealant. Don’t forget about protective equipment – ​​thick clothing, goggles or a mask, work gloves.

How to properly cut a cast iron bathtub

We immediately warn you that the cutting process is a labor-intensive task that requires effort, endurance and certain knowledge. Anyone who has previously worked with an angle grinder knows the technology for cutting thick metal sheets, however, here is a special case: the base material is covered with a thick (about 2 mm) layer of enamel. Therefore, you need to cut carefully, slowly, in sections of 5-10 cm, pausing to allow the disc to cool.

The ideal place for cutting is the street. If the procedure takes place indoors, it is necessary to protect surrounding objects, since cast iron dust can ruin good things. It is better if the container is in an upside-down position - this makes it easier to make a straight cut.

Why do you need a foundation?

Having cut the main part of the future stove into two identical fragments, you can begin building the foundation. It is the main stabilizing element of the structure. Without a solid cement foundation, regular shrinkage will occur (do not forget about the weight of the metal) into the soil, which can render the brickwork unusable.

The technology for constructing a concrete foundation may be different. A small stand can be built without additional supports; to build a tall one, you will have to put together a blind area. the main objective blind area - to give concrete base smooth shape.

Device diagram concrete foundation with blind area

Detailed instructions for assembling the structure

We can say that everything preparatory work finished and you can start assembling the stove from a bathtub sawn in half. At this stage, you should decide on the type of facade. There are two popular solutions: a completely metal front surface or partly made of brick. The doors are made of metal in any case. You don’t have to cut them yourself, as they are sold in specialized stores. ready-made options– from simple rectangular doors to decorative ones with forged elements.

Installation of a bathtub on a foundation

When the foundation concrete has set, one half of the product is installed on it, bottom down, with a cut towards the future facade. This is a combustion chamber on which corners can be secured in advance to support the grate. At least 4 pieces are needed to secure the grille from all corners. The distance from the bottom to the corners is 15-20 cm. The construction of brick walls begins after the concrete has fully matured. This may take from a few days to 2-3 weeks, depending on the weather.

Installation of metal sheet

To separate the lower half (combustion chamber) from the upper half (cooking and oven), it is necessary to cover the already installed part of the bath with a thick cast iron sheet. If it is missing, it can be replaced with a steel analogue. A hole for the chimney should be cut in the ceiling sheet. Ideally, the diameters of the hole and pipe should match. To cut an even circle, you should apply a marking, drill it around the entire circumference with a small drill, and then go through it with a grinder. The irregularities are ground down with a file and cleaned.

This is what the metal sheet separating the furnace chambers looks like

Fixing the chimney pipe

We insert the chimney into the hole, firmly fixing it. If there is a small gap between the elements, fill it with fire-resistant sealant. There is a second way to install the chimney - from the back. If you remember, it is in the “rear” part that there is a small hole for draining water. In this case, the configuration of the structure will change slightly, since the pipe will be routed along the rear wall.

Having secured the chimney to the sheet, we coat the contour of the container with heat-resistant sealant and connect these two elements. The lower chamber - the firebox - is ready.

Top attachment

Metal horizontal panel is the basis for the second half of the bathtub, which must be installed on finished design, but inverted. In this half it is also necessary to make a hole for the chimney so that after installation the pipe stands strictly vertical. We twist all three connected elements along the edges using bolts (10 mm), at intervals of 15-20 cm. The “heart” of the stove is ready - the process of burning wood and cooking will take place in it.

Connecting all parts with bolts

Installation of grate

The grate separates the two chambers of the firebox: the process of combustion of logs takes place on the upper grate, the lower one is the ash chamber. Over time, ash accumulates in it, so it is better to provide it with a separate door - for free access to combustion waste. We fix the grate on the corners screwed in advance. You don’t have to use fixing elements, but then when laying logs the grate will move and tilt to one side.

Construction of brickwork

Bricks (solid, ceramic) are laid around the perimeter of the base so as to cover the back wall and sides. The façade can also be partially decorated, leaving space for doors. First, we draw the markings of the first row according to the diagram, then we build the walls. The upper boundary of the brickwork should be at the level of the cooking compartment, and the entire lower part should be slightly larger in size than the upper.

Decorating the bottom with brick

When forming the front wall from brick, we do not forget about the doors: we mount the blower at the very bottom, under the grate, and the main one – a little higher. To close the upper chamber, we make a metal damper with a handle protected from heat. The damper, which resembles an analogue of a Russian stove, must match the shape of the curve of the bathtub so that there is no gap on the sides.

Insulation of the cooking chamber

To protect the oven chamber from rapid cooling, it should be “covered” with a thick layer of material that does not conduct heat well. For these purposes, a thick clay-sand solution is usually used. To prevent cracks from appearing, add a little lime to the mixture.

Table of the ratio of components in mortars

In order for the solution to adhere well to smooth surface, it is pre-covered with a fine mesh mesh. It prevents slipping and reinforces the insulation layer. Clay mortar Apply in layers, leveling with a spatula. As a result, its thickness should be about 6 cm.

Decorative design of the stove

A do-it-yourself stove from an old bathtub will look much more interesting and attractive if you decorate it with outside. For finishing you can use:

• ceramic tiles (whole elements or fragments)
• artificial or natural stone;
• self-made tiles.

The upper part is usually covered with whitewash or paint. Natural brickwork also looks appropriate if there are already brick objects on the site (house, gazebo).

Alternative use for an old bathtub

A barbecue stove convenient for outdoor use is not the only product that can be built from old cast iron. Using the heating function of individual fragments, fireplaces or sauna heaters are built from them. Using painting and others decorative types finishing, doing garden furniture- sofas and armchairs. The most common application that does not require cutting or welding is the device small pond. The bathtub is placed in a pit, surrounded by aquatic plants and decorated with stones.

Fireplace from a cast iron bath

Country houses made using handicraft methods are of particular value - they are made with soul and love for their work. Today you will hardly surprise anyone with an expensive purchased unit, but a self-assembled stove is a truly amazing work of art, and also very necessary and useful.

Made in Soviet times, the cast iron bathtub is a durable, solid and very heavy product. However, the once white enamel loses its former shine, and it is unlikely to be restored. It’s a shame to hand over a bathtub by the weight of scrap metal or drag it to a landfill. What else can you do with it? Some owners country cottages and the dachas suggest using it cast iron product with greater benefit: make a stove with your own hands from an old bathtub. Agree, this is original and rational. Such a stove will be able to decorate the estate and make it possible to prepare delicious dishes.

Required materials and tools

To build a stove from a cast iron bath yourself, you will need to stock up on the necessary tools.

Here is their exhaustive list:

• grinder (angle grinder), as well as discs for it (cleaning and cutting);
• electric drill and set of drills;
• equipment that allows gas cutting of metal elements (if available);
• spanners different sizes, hammer and pliers;
• crowbar and shovel;
• container where the solution will be mixed;
• spatula and trowel;
• tools for taking measurements: building level, plumb line, tape measure, metal corner;
• a welding machine (will be needed to install the chimney), as well as electrodes for it and a protective mask;
• hacksaw for woodworking.

The main element of the stove is a cast iron bath. However, the stove has significant weight, so it must have a foundation. For its construction, a certain amount of sand, cement mortar, brick, as well as clay and water is required.

Making a stove from a cast iron bath is much cheaper and more profitable than buying a new one

In addition, you will need:

• corner (metal);
• metal sheet (4 millimeters);
• a grid of a certain size;
• pipe required for the manufacture of a chimney (length - from 2 to 3 m, diameter - from 10 to 12.5 cm, wall thickness - from 3 mm);
• hinges for doors;
• Rabitz;
• polyethylene film (necessary for waterproofing the foundation);
• board (thickness - from 2 to 2.5 cm);
• slats (2 by 2 cm);
• nails.

Making a stove from an old bathtub with your own hands: step-by-step instructions

So, let's look at how you can make your own stove from a cast iron bathtub.

For country house you can make a stove from an old cast iron bath, which in terms of strength and service life will not be inferior to models from the factory

First we build the foundation.

1. Using a cord and stakes, we mark the foundation.
2. We dig a trench, the depth of which should not be less than 50 cm. We put layers of sand and gravel on the bottom, and then compact them thoroughly.
3. Above sand and gravel cushion put waterproofing layer, usually being polyethylene.
4. To raise the base of the foundation, we build formwork in the center. Typically, general formwork is built, and pouring is done to a height of at least 30 cm.
5. The free volume is reinforced and filled with a solution of cement and sand (1 part cement to 3 parts sand). The volume can also be filled with brickwork.
6. After pouring the foundation, it must harden.

Now it's time to design the stove itself.

To this end, we perform the following actions:

1. Cut the cast iron bath crosswise. This must be done carefully, since cast iron is very fragile. If the movements are sloppy or abrupt, you can damage the bath so that it becomes unsuitable for subsequent work.
2. We take half of the cut bathtub, and then install it on top, and in such a way that we get a structure that looks like a capsule with a cut.
3. Next, for work you will need a sheet of metal with a thickness of more than 5 mm. For the design you will need two halves of the bath and a metal sheet, which is necessary to separate the lower part from the upper (the area for fuel from the place where food is prepared).

A hole for the chimney must be provided in the sheet of metal, located near the back wall. The chimney starts from the lower chamber and then goes through the entire stove.

In order to fix the two halves of the bathtub and the metal sheet with maximum reliability, it is advisable to use fasteners. To prevent smoke from the chamber located on top, a special sealant called stove sealant should be used.

The chimney is attached to the metal sheet using welding.

1. We install the stove blank on the bricks. To prevent the structure from falling, it is very important to level it. Before you start welding, it is recommended to warm up the cast iron a little (for example, the material will become much more pliable if you heat firewood in the chamber).
2. In the lower chamber, we close the front part with a metal sheet, making a hole in it first large diameter(wood will be thrown into the chamber through this hole).
3. We make chamber doors for the firebox and for cooking.

Well, a simple and quite functional stove is ready. All that remains is to decorate the structure, making it a decoration of the yard. The stove can be painted, for example, in a folk style. No one will even think that a cast iron bathtub was used to make the product.

Sauna stove from an old bathtub

A cast iron bathtub can form the basis of a good kitchen stove. However, it is quite possible to make an excellent sauna stove from it, and with your own hands.

Cast iron is environmentally friendly clean material, therefore, no harmful substances are released when heated

Building a bathhouse and equipping a stove in it will require certain skills, so before construction it makes sense to consult a professional.

There are certain requirements for sauna stoves:

• All such furnaces must have enough power (thermal), and they must also have a large range of adjustment.
• To change the heat and moisture regime, the device is equipped with a heat accumulator and a steam generator.
• Furnaces should have the ability to adjust the convention.

So, from a well-worn cast iron bathtub you can make a simple two-tier sauna stove that meets all the requirements listed above. Lower tier stoves are one half of the bathtub, which is facing the wall with its cut and the convex part at the top. The entire structure from the outside must be lined with bricks. The required steam generation is provided thanks to the stones that cover part of the “bath-oven”. Heat accumulation occurs in the upper chamber.

The operating principle of the stove is quite simple. When passing through a cast iron bath, the gas warms up the stones, then reaches the opposite side the so-called bread chamber. Then the gas flow makes a “dive” (goes down and immediately up), after which it exits the pipe. To prevent smoke emissions, a damper is located at the bottom of the stove.

Cast iron stoves: let's evaluate the advantages

Why is a homemade cast iron stove (in our case, a stove made from a cast iron bathtub) so profitable? Cast iron is one of the the best materials for this purpose, however, factory-made cast iron stoves are quite expensive.

This material has gained popularity due to its strength, although it is fragile. In addition, it is resistant to critically high temperatures and unpretentious in operation.

Modern cast iron stoves are especially popular Comparing cast iron and brick oven , let's say that thermal conductivity is much better for the first. And since in the bath high temperature

not maintained constantly; the material should not be sensitive to temperature changes. IN winter time

A bathhouse at a summer cottage is usually not heated, which is why the brick sometimes begins to crumble, but cast iron has no such problems. As for fire safety, only a new brick stove is absolutely not dangerous. With an old product, sparks may break through cracks.

Steel competes seriously with cast iron. In terms of heating speed and strength, steel stoves are not inferior to cast iron ones, but the service life of the former is significantly shorter. Perhaps the main weak point steel furnaces is their susceptibility to corrosion. With cast iron this problem is not as pronounced.

By making a stove from a cast iron bath, you will become the owner of a convenient and reliable device, functioning perfectly in any conditions. From such a bath you can also make a very original fireplace for the dacha. It is especially suitable for those who are currently laying the brickwork for a country house, since the fireplace is, as it were, “recessed” into brick wall, and this makes it possible to use space with maximum benefit.

Video: Universal miracle stove made from a cast iron bath

Having assessed all the advantages of cast iron (for example, compared to steel) and the relative ease of making a bathhouse from a cast iron bathtub, we note that making a bathhouse yourself from this material is very profitable. So, if you want to make a stove with your own hands from an old bathtub, purchase the missing material, pick up the tools and get started!

Craftsmen, of whom there are plenty in every city with an average population, have long mastered the production of solid fuel boilers and stoves from steel or brick. Moreover, most of their products function quite reliably and efficiently. And only cast iron, as a material for homemade heaters, remained on the sidelines until recently. But there is already an initiative here, and in this article we are ready to present it and discuss the question of how to make a stove from a cast-iron bath yourself.

Homemade garden stove made of cast iron

Previously, it was not without reason that craftsmen ignored cast iron, although as a material for manufacturing heating equipment it is in high demand. The fact is that gray cast iron is difficult to process mechanically, and manufacturers of heating equipment use industrial casting to give it the required shape. These technologies are not available at home, so to make a stove you can take some kind of cast iron product and remake it, which was done by one of the home craftsmen. An old cast iron bathtub, of which there are still plenty left from the Soviet era, was suitable for this purpose.

Since this material is extremely hard and fragile, processing it requires not only a lot of patience, but also good metalworking skills. The garden stove shown above from an old cast iron bathtub is good example such skills and patience, and our task is to explain how this is done. The first step is to take an angle grinder with a working diameter of 250 or 300 mm and stock up cutting wheels on metal, then carefully measure half of the bathroom and draw a cutting line. In this case, the width of the cutting wheel should be taken into account.

Procurement work

The next operation is to cut the cast iron bathtub in half, strictly along the line. The work is hard and long, but quite doable. When there are 2 halves of a product, they must be fastened together. Again, welding cast iron parts at home is not possible, so the halves are bolted together, and a steel sheet is laid between them, separating the firebox from the oven.

For this purpose, the master took a corrugated sheet metal about 8 mm thick, you can follow his example. If you have regular smooth metal of this thickness or a little more, it will also work, although it is better not to use a sheet thicker than 10 mm, this will affect the heating time of the oven. It is better to cut the blank from the sheet in advance, but if the available metal is small more sizes bathroom, then this can be done later, locally.

Another step towards the goal is marking and drilling mounting holes in cast iron bath and a metal gasket. Let’s say right away what you will need high quality drills and the ability to sharpen them, because cast iron will not just give up to you without a fight. To make 4 through holes, you will need to patiently sharpen the drills several times, while maintaining the working edge angle of at least 120º. Drilling different instruments, from small to large diameter, at low drill speeds, periodically lubricating with machine oil.

And the last labor-intensive operation is cutting a hole for the chimney pipe. While it is not very difficult to make it in a metal spacer 8 mm thick, then you will have to tinker with the bathtub. It is best to cut through the place where the bathroom drain used to be; it must be expanded to a diameter of 100 mm. When this operation is completed, you can begin assembly. First, the chimney pipe must be welded to a metal sheet.

Any knowledgeable stove maker will tell you that this place is the weakest in the entire design of any steel heater; this joint burns out first. A cast iron stove from a bathtub is no exception, so it would be more correct to pass the pipe through a sheet and scald it on both sides.

Assembling the furnace body

When the element is ready, it is installed on the lower part of the bathtub, and the second part is placed on top. The craftsman used a special sealant at the joint as a seal, but asbestos or basalt cardboard can also be laid. Then the holes are aligned, the bolts are installed and tightened. At this point, the stove body can be considered ready.

In order for a homemade stove from an old bathtub to acquire a finished look, you need to cut out and attach a metal front panel; a sheet thickness of 5-6 mm is sufficient here, and then make doors and a grate. This entire structure should be installed on a pedestal made of brick. In order not to heat the street, metal surfaces combustion chambers and ovens must be insulated with a layer of basalt fiber and lined with any convenient material.

Since a bathtub can be used to make not only garden stoves, but also heaters for different rooms, then in the latter case, insulation of the body is not required so that the walls can freely transfer heat to the air environment of the room. Then the front panel will take on a different look, and brick base will have to be refined finishing materials. At the same time, there is no need to build brickwork in front and behind the stove so that the firebox is freely washed with air. However, another craftsman can replace the brick support with a metal one, here everything is in your hands.

About the advantages and disadvantages

The main advantage of a home-made cast iron bathtub stove is its almost zero cost. The main investment is your work, and you will have to put in a lot of it. The second advantage is durability, it directly depends on the service life of welded joints chimney and the front panel with doors, and the tightness of the main elements. As for the bathroom, even the enamel on it will not burn out right away.

For reference. IN Soviet time for baths and kitchen utensils Silicon-based enamel (quartz sand) was used. It was applied to metal products in 2 layers (primer and glossy layer) and heated to a temperature of 860 ºС to quartz sand melted, and then cooling was carried out using a certain technology. This kind of coating, which protects cast iron, served for decades and was destroyed only by strong impacts with a heavy object.

From a heating engineering point of view, operating efficiency homemade stove unlikely to exceed 40% due to direct output flue gases from the firebox to the outside, they transfer only part of the heat to the oven, and the rest goes into the atmosphere. For this reason, a similar design is used as a sauna stove, where efficiency indicators are not so important, the main thing is temperature. True, only one half of the bathtub is taken and placed on a brick-lined base, and then erected side walls and a heater is installed.

Half of the bathtub serves as a reliable and durable firebox, which will not burn out very quickly, and will give off heat to the heater perfectly. As a result, less red will be spent on construction ceramic bricks, which will significantly reduce the cost of the steam room as a whole. The only caveat is that sauna stove correctly join two materials with different coefficients of thermal expansion - brick and cast iron.

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 prepared. In the upper cut-off part of the bathtub and in the metal sheet, through holes are made 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 from metal sheet a blank in the size of the resulting half 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 of brick or, for a larger structure, poured. 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.
