Makeshift stoves for metal baths
Homemade stoves for the bath. always a unique thing, thanks to which the atmosphere in your steam room will always be cozy and at home pleasant. This is a creative work, in which you put your heart and soul, and perform the work based on your personal requirements and wishes. You can decorate the homemade stove in any way you like, you can see examples on the photo.
However, the appearance of the stove is not the most important thing to consider when getting started. The main thing. it performs its main function. heating the sauna. Many people collect stoves from different materials, using different drawings, but the most popular model is a wood-fired metal stove, which is also called a sauna stove.
Requirements for the sauna stove
With a competent approach to the work, a homemade sauna stove will not be inferior to its factory-made counterpart in any way.
When selecting the type of furnace, the key features of the bath itself must be taken into account. However, regardless of the type of design option chosen, a sauna stove must meet several basic requirements that are relevant for any unit of this type.
Among the most important requirements should be noted the following points:
- the presence of the necessary thermal power and the possibility of regulating it;
- availability of a steam generator and heat accumulator in the design. These devices will allow to change the humidity and temperature regimes, which will make visiting the steam room as comfortable as possible;
- absence (in practice. almost absent) of surfaces heated to a temperature above 150 degrees;
- the possibility of regulating the convection.
In addition to these points, each sauna stove has its own requirements for size of the furnace, fire safety indicators, etc.

Blueprints for a stove structure
Before you begin work, you must first understand what are iron stoves in the bath. Furnace is a device designed to burn wood, above the furnace which is placed a of stones and a water tank in the right place. If the sauna is not only a steam room, but also a shower room, then it is advisable to remove the tank and install a register (water heating system) in the furnace.
All the drawings of furnaces for baths are largely similar to each other. On the basis of the drawing, prepared in advance with individual dimensions for the bath, you can make your own stove of the necessary modification, taking into account your own needs and preferences.
Stove with remote tank is a stove with welded for stones. It can be placed entirely in the bath (with the firebox door), or you can put its front part outside the bath room in the next room, extended with the help of pipes behind the partition. The design can be planned in different ways, the main thing is that it is convenient.
To give the heater an aesthetic appearance, it is covered with red refractory bricks for facing. If you are able to cook the iron yourself, you can use already available ready-made drawings of sauna stoves.
The stove is made of 35 mm thick steel.
Between the ash-pan and the firebox there is a grate, through which the ash can freely fall. The grate must not have large cells so as to hold the coals in the furnace. A grate with the mesh size of 10-20 mm will promote good air flow into the furnace and prevent coals from prematurely falling into the ash-pan.
If there is a desire to extend the furnace by moving the door of the fuel box outside the steam room, the furnace is extended with two tunnel-shaped metal strips by the thickness of the wall. This way only the stones and the chimney can be put in the sweat room. The same cast iron grate is placed under the stones, which will be able to withstand a sufficiently high temperature for a long time.
The drawing of the furnace can provide for the angular location of the structure. You can put the stove in the center of the steam room, making it out of a barrel, and lined with wild bricks.
Types of designs
They differ in structure, the principles of work. Let’s analyze each of the types in more detail.
The stones are placed on top of the stove structure, not covered with anything. Due to this the steam room is heated faster, the temperature reaches 100 degrees. But the humidity in the room is low, so the heat is dry.
The open type is best suited for installation in the sauna, where a high temperature and low humidity are required.
There must be not many stones, otherwise the upper layer will be poorly heated and the steam room will not be warm enough.
To increase the level of humidity and the output of water vapor, the hot stones are simply poured with water. One or two buckets will suffice, which will give up to 15% moisture.
To improve fire safety and reduce the risk of burns, it is recommended that around the walls of the furnace to make masonry of fire bricks or make a partition of wood.
For heating the sauna, it is important that as much of the stove area as possible is in contact with the air space. This helps heat up the air in the steam room more quickly.
Enclosed (encased in brick or stone)
Closed furnace. an attribute of the Russian bath, where you need high humidity and a comfortable temperature.
If wood fuel is chosen for heating, you will have to prepare large stocks in advance. Such a furnace is long gaining the desired temperature, but reaching the right level, gives a good heat output and retains heat for a long time.
Closed structures are great for large baths, where there is not only a steam room, washing room, pre-bath, and also a rest room.
One of the advantages. closed stones. So there is no risk of getting burned.
The factory economical models have a double casing with a gap for air exchange between the walls.
Most manufacturers design consists of a high box with grates, double shutters (serves as a firebox). Flue pipe comes out of the box throat. Stones are also placed in the throat.
There are on sale devices with combined types of fuel:
They do not need to be constantly monitored. Easy enough to set at the desired temperature.
Gas and wood stoves allow you to heat the room with both gas and wood. There is a removable gas burner and grate, furnace chamber, ash-pan (for firewood) inside.
Beginners’ Guide to Melting HDPE. How to Make a Recycled Plastic Pen
- Monobloc. With heat exchanger, furnace chamber. Non-removable type gas burner, covered with steel sheet.
- Paired. Have two separate combustion chambers for wood and gas.
- Reconfigurable. Versatile device. Can be reconfigured for each fuel.
The first two types do not need adjustments, since you can switch from one fuel to the other.
To connect the gas and wood boiler, you will have to order the development of a project from specialists, obtain a permit for installation.
Gas used main or liquefied in cylinders.
Electric and wood-burning design allows to successfully heat the sauna with electricity, wood (optional). And the main raw material is wood. When they burn out and the temperature drops, the electric heater starts working automatically. On the sides of the product are two heating elements. Such stoves operate from 220 W, with three-phase voltage of 380 V.
The advantages of combined stoves. the possibility of rapid heating of rooms of different sizes, ease of installation and compactness.
Owners can choose what fuel to heat their bath. But such constructions are many times more expensive than simple wood-burning stoves.
Stacking of stones
The efficiency of the makeshift sauna stove will largely depend on the stones. the correct selection of them and their laying in the heater.
Even on a small stove requires no less than 50-kilogram stack, but it is still better for the family bath to focus on 80. 100 kg.
It is better to choose cobblestones of round shape, even gray color, without surface imperfections (cracks or breaks). It is desirable to have stones of various sizes, from 50 to 150 mm.
Granite for the sauna stove is absolutely unsuitable. Firstly, its structure is unstable to the frequent processes of intense heating with the simultaneous action of steam. very quickly the destruction will begin. Secondly, granite always contains mica inclusions, and they can emit quite toxic vapors when heated.
Jadeite is one of the best options for the sauna heater. In addition to natural beauty, it is also attributed medicinal properties
The best materials, in addition to the usual natural cobblestones, are considered talcochloride. Basalt or jadeite. You can buy such stones of different sizes in specialized stores.
It is very important to arrange the stones correctly. Start laying them out so that the largest, most massive ones are at the bottom. They will not obstruct the passage of heat to the stones above and will create a strong reserve of heat. Then the medium size stones are placed, and only at the very top are the smaller stones.
This order gives the stones a final temperature of 300º to 400º, just the right temperature for dry steam. If the water gets on the well heated stones, the evaporation occurs literally instantaneously, and is accompanied by a characteristic crackling sound.
If the stones are flattened, their spatial orientation must be taken into account when arranging the stones. Their long sides should be placed along the main stream of heat, otherwise a kind of “locking” will happen, when the lower stones will overheat, and the upper ones will not reach the required temperature.
If the stones are not placed correctly the overall curative effect of the sauna will be drastically reduced. Steam will very quickly begin to “get heavier”, and although. Probably the total temperature in the steam room will not significantly decrease, staying in it will bring more harm than good. in an overmoistened room simply becomes nothing to breathe.
for different types of sauna stoves stones
So, the stove for the bath with your own hands. the task is quite doable, if in the manufacture take into account all the technological nuances, and when installing to comply with the established safety requirements. But a self-made stove will not only help to save a rather significant amount of money, but will also be source of pride to the owner when he has the opportunity to invite his friends to the bath.
Metal bath stoves
The photo shows a homemade sauna stove made of metal, which fits perfectly into the interior and works effectively.
Traditional Russian (and not only) baths had stone or brick stoves, as well as stoves made of clay. This is undoubtedly a great option, but it requires a high skill of the stove-mason and quite a lot of space. As a result, such a unit will cost a lot of money, which for many fans of the steam room is quite unacceptable.
In search of an alternative option for the construction of the sauna stove, masters have settled on another material. steel. This metal withstands high temperatures, is easy to handle and is quite inexpensive. availability of steel parts is unmatched: you can buy both new products, and go to the scrap metal dealers and choose suitable for you parts and offcuts.
Among the main advantages of steel furnaces can be identified the following list:
- The low price of the material, its availability and prevalence;
- High strength of metal and its resistance to high temperatures, humidity, mechanical and shock loads, high pressure readings;
- Metal equipment warms up quickly, which reduces the time to prepare the steam room for use, especially when the bath is in the cottage, and there is no opportunity to preheat the furnace;
- Steel construction has an order of magnitude less weight than the stone one, so it does not require powerful foundations, which also reduces the cost of the bath;
- Metal furnace takes up less space in the room and saves space for other useful objects;
- Simple enough construction, available to non-professional installers;
- The simplicity of metal processing;
- Relatively high reliability of the product;
- No additional permits for installation.
With some skill, a homemade metal sauna stove can look as good as the factory one.
Important! Homemade heating steel bath stoves. it is not only saving money, but also an effective substitute for massive, bulky and expensive stone units.
Like any device, the metal sauna unit has disadvantages.
With all the undeniable advantages of products made of metal have a number of disadvantages:
- The unit cools down quickly enough because of the low heat capacity of metal, so it needs a constant furnace during bathing procedures, which leads to an increased waste of firewood;
- Compared to their brick counterparts, steel is more fire-prone because the walls get very hot and radiate heat. In addition, touching such a wall can cause serious burns;
- Metal products are capable of heating a smaller volume than solid brick stoves;
- Steel is susceptible to electrochemical corrosion, which reduces its durability and may require ongoing repair of weak spots; looks much more solid and beautiful;
- The heat radiated by the stone is much more comfortable and healing than the aggressive infrared radiation of the metal wall.
Important! Some of the above disadvantages can be eliminated in different ways, but in general they will somehow determine the features of the operating mode of your bath, while not being critical or insurmountable.
Furnace designs can be very diverse, it all depends on the imagination of craftsmen and craftsmen who make them.
We will consider the most popular and easy to make examples of stoves. These are units welded from steel pipes and units assembled from sheet steel.
Bath stoves for baths made of pipes are convenient because their assembly requires less welding work, since the pipe itself is already a kind of reservoir, and the simple addition of the bottom and the cover turns it into a closed unit, which can be equipped with the necessary openings, doors, grates, and get ready to furnace.
The same principle is used for assembling the water reservoir and the sauna heater, the chimney is drained. and the stove is ready.
The principle of making a stove from a metal pipe is quite simple.
You can also use ordinary sheet steel for the production of products.
Important! The thickness of metal must be no less than 8 mm, and preferably 10. 12 mm. The thicker the wall, the higher the heat capacity of the device, and this directly affects the cooling time of the heating unit.
Parts are cut according to the drawing, and then assembled by electric arc welding. As a result, you get a cube-shaped sauna stove, which distinguishes it from the cylindrical product of the pipe.
Rectangular profile tells us that the stove is assembled from sheet steel.
Materials for construction
Casting a cast iron frame at home will not work, so the material will be steel. Developed several options for the design of steel bath stoves this:
How to make your very own Cooker Oven for Baking almost everything!
Usually choose the material that is easiest to buy.
If they will be sheets, they must be at least 8 mm thick. If the pipe. a diameter of about 50. 60 cm.
- Spike grate (this can be a prefabricated product or fittings, from which the grate is welded manually)
- Door for the furnace, for an ash door (can be made by yourself).
- The pawls on all the doors.
- A chimney pipe, about 2 m high, 12. 15 cm in diameter.
In the final stage you will need bricks for the screen, stones for the sauna heater and special paint.
A properly made heater will serve you for a long time.
Going to build a stove in the bath, review the options, thoroughly prepare for the work, and if possible, consult with professionals. Safety and comfort will depend on you.
