We built assembly and disassembly sandwich walls, which can be installed for a few hours, in a room intended for a sauna. The advantage of the sauna: If the need arises, can be moved to another location.
It is necessary:
Prepare the room from solid material, certain dimensions (inevstitor must provide this).
Install a ventilation opening, as well as electrical installation, to a certain place, in agreement with the contractor (inevstitor must provide this).
Contractor built a sauna on site.
The interior walls are clad with materials used to build the sauna.
