The Kohler C1 is a 5-person indoor sauna that goes up as a freestanding cabin or tucks into an alcove. It comes with a 9.0 kW FERO electric heater and stones, a Scandinavian spruce interior, solid obeche benches and backrest lighting that glows warmly from behind. Mineral wool insulation, a tempered glass door and Aerotherm ventilation keep the cabin comfortable and the air fresh.

Choose a Graphite Grey or Scandinavian Spruce exterior, add the floor kit if you'd like a spruce walking surface that lets the sauna sit on any level indoor floor, and pick Kohler's white-glove delivery and installation if you'd rather not build it yourself. A licensed electrician will need to wire the dedicated circuit. Kohler backs the C1 with a 5-year limited residential warranty.
