The main element of the steam room is, of course, the heating furnace for the bath. Modern industrial production offers a variety of models to replace traditional wood-burning stoves: on liquid fuel, on gas with a metal body, working on pellets. Factory products are equipped with a variety of functions and economical use of fuel. Yes, and care for them is minimal.
There are many options for homemade devices for a steam room, depending on the type of room. For example, there are so-called cold furnaces, that is, those whose outer walls do not warm up above 50 ° C. This is an important advantage, because this design does not get burned. Such units require a long continuous kindling. Heating takes place through special air ducts. They absorb air from the floor and heat it up by passing through the combustion chamber. Warm and soft steam comes out from above, without burning anyone. In such a bath, it is easy to regulate the level of humidity and the temperature of heating.
Unlike the "cold", the "hot" furnaces quickly and efficiently heat up the steam room due to the heated walls, the temperature of which can reach 100 ° C. Careless touches of them threaten with burns, and the degree of air heating in this case is difficult to control. And it threatens to heat stroke.

Good and simple The "cold" furnace for the bath constructively looks like this: the combustion chamber is made of refractory bricks, an ashpit is located under it. From above, to preserve the heat, cobblestones are laid out on a steel or cast-iron grating. Their mass is calculated from the ratio: for 1 m 3 steam rooms it takes 20-30 kg of stones. This proportion is true for continuously operating devices. If heating occurs periodically, that is, after warming up the room to the desired level, it is quenched, then the amount must be increased another 2 times. Sometimes, iron pigs are added in a ratio of 20% to 80% of stone to better retain heat.
The walls themselves, in addition to bricks, can be made of ordinary or rubble stone. Sometimes for construction they take granite or naked. The weight of each element is from 1 to 5 kg. Do not try to build from silicon - it will simply burst from heating.
Only clay with sand can be used as a binder solution when laying the stove. Conventional cement mortar will not withstand high temperatures and will not last a year.
Clay is soaked in water for several days and mixed with sifted sand to the consistency of thick cream. Sand is preferable to take not river, and mountain. Its edges are uneven, unpolished and provide better grip.
A kiln of baked bricks with stones weighs a lot, so you have to make a foundation for it. To do this, a pit of 70 cm is enough.
15 cm of sand and crushed stone fall asleep at the bottom. Then everything is filled with a layer of concrete, preferably with reinforcement. From above, the frozen foundation is closed with rolls of roofing material for waterproofing.

Metal bath stove
Unlike brick structures, metal units are compact and quickly warm themselves and heat the room.
A foundation is also needed for a metal stove. Although its mass is much less than its stone counterpart, however, and under it you need to make a reliable foundation.
The foundation for a metal furnace
The starting material is heavy-gauge steel or large-diameter pipes. By design, this furnace will be similar to stone. The only difference is the firebox. It is customary to make it a two-chamber, so that in the second compartment fuel afterburning can occur. This scheme allows you to increase productivity by 20%.
The body must be fully welded - tack welding is not suitable here.
The main disadvantage of a steel furnace can be considered as an extensive hot surface that is dangerous for people. However, it is easy to fix. After installation, the body is simply lined with refractory bricks, leaving a gap for convection.
