Finlandia Prefabricated FPF Sauna Rooms

Finlandia prefab Saunas are complete, freestanding, self-contained rooms engineered with fast and effortless installation in mind. They can be put anywhere you have an open space. The space needs to be a little larger than the actual Sauna room size. You must provide a waterproof floor (concrete, tile, or vinyl). FPFs contain all interior and exterior parts. Our prefabs can be installed by the homeowner over any hard-surfaced waterproof floor. We have an exclusive locking system inside each of our panels which makes our prefab the fastest to install, the strongest, and the most custom looking Sauna on the market. Average panel width is 24" so wall sections can be easily brought through the house. The area where the Sauna is to be installed needs a minimum ceiling height of 87", or if the Sauna room is 8'x 8' or larger the minimum ceiling height is 89". Our wall sections go together without any screws, splices, or bolts. Electrical hookup is made easy because we have electrical conduit sealed within the walls, and the optional wall control is pre-mounted. Electrical power enters at the top of the Sauna room standard.
