You will not believe what can be done from an old cast-iron bathtub - stove, barbecue and other unusual things. Making a stove from an old bath with your own hands Stove for giving from an old bath

Do-it-yourself stove for a bath from a cast-iron bath

Old cast-iron bathtubs are made of durable material that can withstand any stress and temperature, so not using it a second time for the benefit of your health is a big mistake. In addition to its strength, cast iron is also an environmentally friendly material, therefore, during heating, you can rest assured that no harmful substances are released in the bath.

How to make a stove with your own hands?

Of course, after using the bathroom, it may not be in the best condition, but all its qualities remain the same, for example, it still remains strong and durable, so it is quite possible to give it a second life. Naturally, many who have summer cottages use baths such as a water tank, and those who are great at fantasizing can come up with many other interesting things. If you have a bathhouse at your summer cottage, then you can make a stove from the bathtub with your own hands, which will be very expensive in the store. A material such as cast iron is excellent for creating a furnace, because it has such advantages as:

Great durability.

Excellent thermal conductivity.

Withstands even the highest indoor temperatures and humidity.

It is easy to operate and does not require any special maintenance.

You can use an old bathtub for the construction of such types of cast-iron stoves as: a street one, which will be located in the garden, as a fireplace for a country house, and, of course, for a bathhouse. Such options can well be realized with the help of your own hands.

Making a stove, how to properly prepare a bath?

You will not be able to fully use the container, so you will need to saw it. To make the cut correctly, you need to approach this issue with great responsibility. You will have to work with a grinder; you will also need to prepare several discs for metal in advance. It is imperative to take care of safety precautions, so special glasses, a respirator and gloves are worn. All actions must be correctly performed according to the recommendations given below:

1. Before proceeding with sawing, you will need to make calculations and markup for the future cut.

2. The first step is to cut the enamel layer, this is done in order to prevent chips at the edges.

3. Directly the cast iron itself is notched in small pieces, while it is worth taking breaks.

4. When half of the bath is cut, it is required to substitute supports under both parts, which will not allow further damage to the tool, and the material itself.

Experts say that cutting is best done at an angle, then the enamel will not exfoliate much.

Rules for making a stove for a bath from an old bath

The process of making a stove for a bath is very complicated, because you have to take care not only of quality, but also of safety. The fact is that the stove will be located in the bathhouse building, so there are parameters for the installation, for example, it is worth taking into account the thermal power and its change, the ability to produce steam, as well as the ability to regulate convection flows. As soon as the bath is sawn, you can begin to build a stove in the bath. You will need one half of your cut, but sometimes you can use two tub parts as well.

To build such a furnace correctly, you must be guided by the following expert advice:

To make a stove on your own, you initially need to prepare a foundation, it is made of concrete mortar, sometimes a filler is used, broken brick is perfect for this, which is able to withstand even a large load.

One part of the bath is laid on the foundation, while it is important to make sure that it looks with the curved part up. The cut should be built into the wall with access to another room, where the heating of the bath will take place directly. For safety reasons and in order to implement the design idea, the hole is closed with brickwork, then the furnace and blower door is installed.

When half of the bath is properly installed, then at a distance of 10 centimeters, walls of refractory bricks are also erected, which will be equal to the height of the cast iron container. The space that forms around must be filled with stones, it is they who will warm the room to the desired temperature.

Alternatively, you can build an ordinary sauna stove, which will consist of two tiers, with all the heat going to the upper tier. The principle of operation of such a furnace is based on the passage of gas through the bath, due to which the stones are heated, and then the heat already flows down and returns up again, after which it is released from the pipe.

One cannot but agree that the decision to create a stove for a bath in this way at your dacha from a bath is creative, but it is also considered rational from the point of view of unnecessary costs. For construction, it is absolutely not required to use any material, except for an old cast-iron bath, you can also make a stove yourself without involving outside specialists, of course, this option should be considered if you have at least some experience in building baths. It is important to note that another advantage is the durability of this equipment, because cast iron is a durable material that can withstand high temperatures and moisture, which means that you can enjoy a hot bath for a long time. In addition to saving money, you also get a durable oven in addition, which is difficult to find in the construction markets, because most materials today are not of the same quality.

More recently, I came across a brilliant idea of ​​creating a garden stove from an old bathtub. The idea is so simple that any man can bring it to life. There are a lot of benefits from such a device, because it can be used as a stove, outdoor fireplace, barbecue and so on.

In order not to tire the reader, I suggest that you familiarize yourself with the process of creating this dacha masterpiece.

For the stove you will need:
- old bath;
- a pipe, it will also be a chimney;
- bricks, old and unnecessary;
- metal sheet with a thickness of 5 mm;
- grinder or any other device for cutting metal.

The first stage is the most difficult, since the bath will need to be cut across into two absolutely equal parts. In one of the parts, a hole should be made along the pipe diameter. We make exactly the same hole in the sheet of metal that we managed to find. When the most difficult stage is left behind, you can proceed directly to the assembly of the structure.

1. We put one half of the half of the old bathtub, in which there is no hole, as usual. On top of this half, place a sheet of metal. Attention! The hole should be in the area of ​​the far wall. Now on the sheet, we put the second half of the bath upside down, that is, so that the bottom looks into the sky.

2. Our miracle oven is almost ready and it remains to add reliability to the whole structure. The edges of the stove bath must be tightly fastened. For this, bolts are suitable, preferably large ones. The bolt holes are, of course, better drilled beforehand. As a result, it should turn out so that the metal sheet will be tightly clamped between the two halves of the bath.

3. It's time to build a chimney. Insert the pipe into the hole on the upper half and lower it a couple of three centimeters below the metal sheet. If the holes for the pipe turned out to be of a larger diameter, then you have to be smart in order to fix the chimney. A zealous owner who does everything conscientiously will probably resort to welding and will do the right thing. For greater reliability, the welding seams are sealed with a sealant.

4. So the garden stove from the bath is ready, the final touch remains - the creation of the pedestal. We make a stand for the stove from bricks, stones and other materials that you have on your site. Do you have construction waste that you still can't take out? So turn on a little imagination, because your brainchild deserves a comfortable installation place.

That's the whole trick. Although you can improve it a little. For example, to make the firebox easier to clean from ash, you can put a grate on the bottom. But to achieve good retention and release of heat, just like in a real oven, you can use a stone sheet, which is laid directly on top of a metal sheet.

Now you can cook whatever your heart desires in this oven, from ordinary cereals to aromatic bread.

By the way, it is perfect for cooking jams and other summer preparations, which are so pleasant to get out of the closet or cellar on a cold winter evening.

In the article, we will analyze how to make a stove from a cast iron bath. What materials and tools are required for construction. The advantages of such a furnace.

If you have an unnecessary cast-iron bathtub at your disposal, do not rush to throw it away or hand it over to the metal. From this bath, you can easily make a wonderful barbecue oven at your summer cottage.

An oven from such a seemingly useless bathtub will be a wonderful decoration and a wonderful oven for preparing various dishes. Cast iron is a metal with high thermal conductivity and excellent heat storage properties. In such an oven, it is good to cook both ordinary food and bake baked goods and various delicious dishes.

Furnace advantages

The mere thought of making such an oven can help solve some of the accumulated problems and reveal the following advantages:

• year-round opportunity to cook your favorite food
• a beautiful stove will be a good decoration for a summer cottage
• savings in construction costs
• saving gas, electricity
• getting rid of unnecessary bath

How to make a stove from a cast-iron bath

The bathtub must be divided in half. The halves are connected together with the concave part outward. Between the separated halves, a sheet of metal with a thickness of 10 mm or more lies, which separates the firebox from the place where the food will be prepared. Through holes are made in the upper cut-off part of the bath and a sheet of metal for a pipe, which in turn will serve as a chimney, the pipe is welded. Then the stove is fixed and an aesthetic look is given to it.

Tool and material for manufacturing

For manufacturing you will need:

• unnecessary cast iron bath
• a metal sheet
• grinder with a disc for metal
• 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 out a workpiece from a metal sheet to the size of the resulting half of the bath
• on the sheet of metal and the upper part of the bath, through holes are marked and cut out for the pipe
• the pipe is welded and brought out through the top
• make markings for fastening the bath halves and the sheet between them

Cast iron bath stove foundation

Since our oven will turn out to be heavy, then we need to do under it. With a foundation, the stove will not shrink and deform. It can be made brick or, for a too large structure, self-leveling. Supports are embedded in it at the required height so that the oven is at the same level.

Assembling the furnace from a cast iron bath

The edges of the furnace part are smeared with a heat-resistant sealant, then an iron sheet with a welded chimney is laid on it.

Parts of the tub with an iron sheet in the middle are pressed together with bolts.

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

If the stove assumes a closed firebox, then in the process of manufacturing the stove, the doors are immediately mounted.

Heat insulation of the furnace

The upper part of the furnace is pulled together with a metal mesh and covered with clay and sand. Then a decorative stone or heat-resistant tile is laid out. If it's easier, then you can just whitewash.

Problems in furnace construction

Problems in the construction of a barbecue oven can occur during the preparation phase when cutting the tub. It must be divided very slowly, without haste. First you need to cut through 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 disc, the cut must be opened with a suitable board or reinforcement.

Do-it-yourself cast iron bath stove video

The video clearly shows a stove from a cast iron bath. The construction device and what materials are required to fasten all parts of the furnace are sounded.

Craftsmen - craftsmen, of whom there are enough in every city with an average population, have long mastered the manufacture of solid fuel boilers and stoves made of steel or brick. Moreover, most of their products function quite reliably and efficiently. And only cast iron, as a material for home-made 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 independently make a stove from a cast-iron bath.

Homemade cast iron garden stove

Previously, it was not for nothing that the craftsmen bypassed cast iron with their attention, although as a material for the manufacture of heating equipment, it is in high demand. The fact is that gray cast iron is difficult to machine mechanically, and manufacturers of heating equipment use the industrial casting method 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 implemented by one of the home craftsmen. For this purpose, an old cast iron bathtub was suitable, of which there are still plenty of them since the Soviet era.

Since this material is extremely hard and fragile, processing it requires not only a lot of patience, but also good locksmith skills. The garden stove shown above from an old cast iron bathtub is a good example of 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 on cutting wheels for metal, then carefully measure half of the bathtub and apply a cutting line. In this case, the width of the cutting disc must be taken into account.

Procurement work

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

For this purpose, the craftsman took corrugated sheet metal with a thickness of about 8 mm, you can follow his example. If there is an ordinary 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 a blank from a sheet in advance, but if the available metal is slightly larger than the size of the bathroom, then this can be done later, in place.

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

And the last time-consuming operation is cutting a hole for the chimney. If it is not very difficult to make it in a metal gasket 8 mm thick, then you will have to tinker with the bathroom. It is best to cut in the place where the bathroom used to have a drain, it must be expanded to a diameter of 100 mm. When this operation is over, you can start assembling. First, the chimney must be welded to the metal sheet.

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

Furnace body assembly

When the element is ready, it is installed on the lower part of the bath, and the second part is placed on top. In the place of contact, the master used a special sealant as a sealant, but asbestos or basalt cardboard can also be laid. After that, the holes are aligned, the bolts are installed and tightened. On this, the stove body can be considered ready.

In order for a home-made stove from an old bathtub to take on a finished look, it is necessary to cut and attach the front panel of metal, here a sheet thickness of 5-6 mm is enough, and then make the doors and the grate. This whole structure should be installed on a pedestal made of bricks. In order not to heat the street, the metal surfaces of the combustion chamber and oven must be insulated with a layer of basalt fiber and revetted with any convenient material.

Since it is possible to make not only garden stoves from the bathroom, but also heaters for different rooms, in the latter case, the insulation of the case is not required so that the walls can freely transfer heat to the air of the room. Then the front panel will take on a different look, and the brick base will have to be refined with finishing materials. At the same time, brickwork should not be erected in front and behind the stove, so that the firebox is freely washed with air. However, another craftsman can replace a brick support with a metal one, here everything is in your hands.

About the advantages and disadvantages

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

For reference. In Soviet times, silicon enamel (quartz sand) was used for baths and kitchen utensils. It was applied to metal products in 2 layers (a primer and a glossy layer) and heated to a temperature of 860 ºС so that the quartz sand melted, and then cooled according to a specific technology. This kind of coating, which protects cast iron, served for decades and was destroyed only by strong blows from a heavy object.

From the point of view of heating technology, the efficiency of a home-made stove is unlikely to exceed 40% due to the direct exit of 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 stove for a bath, where efficiency indicators are not so important, the main thing is temperature. True, only one half of the bath is taken and placed on a base made of bricks, and then the side walls are erected and a heater is arranged.

Half of the bathtub serves as a reliable and durable firebox that will not burn out very soon, and will give off heat to the stove perfectly. As a result, less red ceramic bricks will be spent on construction, which will significantly reduce the cost of the steam room as a whole. The only caveat is to properly dock two materials with different coefficients of thermal expansion in a sauna stove - brick and cast iron. For this, expansion joints are provided, where asbestos or basalt cardboard is laid.

Conclusion

Such non-standard solutions in the design of hand-made stoves are striking in their originality and simplicity. No one will doubt the reliability and durability of a home-made cast-iron stove from a Soviet bath, and yet it was invented and assembled by a master with a head and skillful hands at home. Such products can be made by every homeowner, subsequently they will serve him faithfully for many years.

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

Collapse

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

Forget that your own stove is expensive. All that is required is a small set of tools and some personal time.

Construction device

Most often, a classic-type cast-iron bathtub is used, which is divided into two equal parts. From above, the free plane is covered with a steel sheet to create a closed space.

A concrete floor or brickwork can be used as a base. When the cut is made correctly, there will be no open cracks 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 drilling. It should be understood that a stove from a bathtub, sawn in half, can be additionally sold or donated to close friends, since two stoves can be created from one bathtub.

Conclusion

There is nothing difficult about creating your own stove from a cast iron bath. Follow the directions carefully for fantastic results. Be sure that the quality of the stove will not be inferior to industrial models, but the cost will be orders of magnitude lower than that of the original!
