Frequently Asked Questions
Does the C2 Outdoor Sauna include a heater and stones?
Yes. Every C2 Outdoor Sauna in Weathered Grey Spruce includes a freestanding FERO 9.0 kW electric sauna heater, sauna stones, and a safety heater guard. You do not need to purchase a separate heater unless you want an alternate configuration.
What is the difference between Small, Medium, and Large sizes?
The Small model is ideal for up to 3 people and works well on compact patios and decks. The Medium model serves up to 5 people and suits families or frequent use with guests. The Large model accommodates up to 6 people comfortably for group sessions, social wellness, or spa environments. Each size uses the same core construction and finish, scaled to different footprints and capacities.
Do I need professional installation?
You can choose a standard “sauna only” variant if you have a trusted contractor or prefer to manage installation locally. If you want a more turnkey experience, select a “with installation” variant, which includes professional assembly and placement of the sauna according to KOHLER specifications. In both cases, you are responsible for site preparation, foundation, and electrical service.
Is this sauna suitable for cold or snowy climates?
Yes. The C2 Outdoor Sauna uses mineral wool insulation, rubber seals, and durable exterior construction to support four season outdoor use. In more extreme climates, additional planning around snow loads, wind exposure, and drainage may be needed. Always consult with your installer and review KOHLER documentation for structural and site requirements.
What kind of electrical connection is required?
The included FERO 9.0 kW heater and sauna lighting require a dedicated 240 V, 50 A electrical circuit (consult the technical manual and your licensed electrician for exact wiring and breaker sizing). All electrical work must comply with local codes and regulations.
