Selection of material for its intended purpose and place of use
The roof of the bath can be varied from any material: roofing material, tiled, slate and so on.
As a rule, in a soap or steam room, one small window is made, not higher than one meter from the flooring.
The floors in the bath should be made of polished boards laid on sand or gravel, so that the drained water is where to absorb
The dressing room, which subsequently serves the locker room, must warm up from the furnace, one side of which should go into this room.
The window in the dressing room is not necessary, but you can draw light. But if you do, it should not be big either.
Thresholds in the dressing room and steam room must be made high so that heat is preserved.
