Choose options
Create a dedicated outdoor wellness retreat with the KOHLER C2 Weathered Grey Outdoor Sauna, a premium freestanding sauna designed specifically for outdoor installation. The Weathered Grey Spruce exterior gives this version of the C2 a sophisticated, contemporary appearance, while a warm Scandinavian Spruce interior and solid Obeche seating create a comfortable traditional sauna environment.
Available in 3-, 5- and 6-person configurations, the C2 combines substantial insulation, traditional electric sauna heat and thoughtfully engineered ventilation in an architectural structure designed to withstand outdoor conditions.
Traditional Sauna Heat
A freestanding FERO electric sauna heater with sauna stones provides a traditional sauna bathing experience. Dual thermostatic controls are designed to provide consistent operation, while the exterior digital control panel manages temperature, session time and backrest lighting.
Weather-Ready Construction
The C2 Weathered Grey is engineered specifically for outdoor installation. Its construction includes 2-1/8-inch mineral wool wall insulation, a triple-insulated roof with two layers of mineral wool and an air gap, a waterproof EPDM roof membrane, insulated windows and weather-conscious seals.
Extended roof eaves help protect the exterior from weather while providing shade.
Scandinavian Spruce & Obeche Interior
The light Scandinavian Spruce interior is paired with solid Obeche seating, matching backrests and coordinating sauna accessories. The natural materials create a warm contrast against the Weathered Grey exterior.
Warm 2700K indirect lighting gently illuminates the cabin, with additional exterior lighting surrounding the sauna.
Aerotherm Ventilation
KOHLER's Aerotherm ventilation system provides air exchange within the sauna cabin to maintain appropriate airflow during operation.
Thoughtful Controls & Security
The digital control panel mounts outside the sauna for convenient access and includes a locking protective cover. The front door can also be secured when the sauna isn't in use.
Additional details include a tempered-glass entry door, stainless-steel exterior handle and a Beech wood interior handle designed to remain comfortable to the touch.
