Currently, you can build a sauna both in the apartment and in a private house. First you should install a special cabin, which can be both standard and prefabricated. For construction, the main material is a tree. The main object of the sauna is a stove-kamenka. Its function lies in the heating of water, which will then turn into steam and thus heat the room. Stoves-stoves are divided into electric and wooden. By the way, a ventilation grille with a check valve is often used very popular now in the construction of a sauna.
