The Kohler C2 Outdoor Sauna in Weathered Gray Spruce is a freestanding architectural sauna built for permanent backyard installation — available in 3, 5, and 6-person configurations, with or without professional installation. The Weathered Gray Spruce exterior with organic Douglas Fir cladding delivers a refined, contemporary aesthetic with extended roof eaves for weather protection and improved energy efficiency. Inside, premium Scandinavian spruce tongue-and-groove walls, an Obeche wood bench and matching backrest, and 2700K warm white indirect lighting create a genuinely inviting environment.
A freestanding FERO electric heater with sauna stones and heater guard delivers a traditional sauna experience. Heat retention is exceptional — 2.1-inch mineral wool insulation between the walls, rubber seals, and 0.3-inch tempered glass windows lock in warmth efficiently. The Aerotherm ventilation system manages airflow and ensures a constant supply of fresh oxygen throughout every session.
An external digital display controls temperature, time, and lighting with precision, protected by a locking cover when not in use. Dual thermostatic controls, cool-touch beech wood door handles, and a locking front door ensure every session is safe, consistent, and secure. Exterior surround lighting completes the aesthetic for evening use.
