Have the best of both worlds, an easy to assemble Sauna kit and the Traditional Sauna Experience. The Sauna Heater options all have a large rock capacity for producing plenty of comforting steam when scooping water on the hot rocks. The Modular Sauna Room exterior looks just as great as the interior, which is complete with finishing touches like bench skirting and wooden flooring for the walking area. Compare the weights. Our Prefab Sauna Rooms are constructed of quality solid real wood for durability, not thin lightweight veneers. Sauna Room Kits easily assemble in just hours with included assembly instructions and diagrams.
