It doesn’t matter what type of bath, its construction will take place according to standard stages. Be sure to lay a good foundation to the entire depth of freezing of the soil, despite the fact that in the old days the foundation was neglected. The best material for walls is the tree. Due to its natural properties, it allows the bath to “breathe” through the walls and thanks to this, the bath does not require additional ventilation and supports a special microclimate inside. However, a thick special brick with a thickness of 0.5 m or a lamp stone 0.75 m will also be a good alternative. The surface of the bath must be from durable, light, durable and better inconsistent material. You can make a window in the bath, but to maintain heat, it is necessary that it be placed at the level of meter heights. It is necessary to make at least two doors in the bath — external and for entering the steam room.
