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. You must provide the 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. 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.
