Douglas Fir — Built to Live Outdoors
The C2 is built specifically for freestanding outdoor installation. Douglas Fir exterior cladding provides long-term durability and natural weather resistance — handling moisture, UV exposure, and temperature variation without the need for constant maintenance.
Extended roof eaves provide meaningful protection from rain, shielding the cabin structure and improving heat efficiency — an essential consideration at 5-person scale where maintaining internal temperature matters even more.
Outdoor-First Design
Lockable door, protective cover, and exterior lighting — every detail designed for a sauna that performs and endures year-round outdoors.
Designed for Outdoor Conditions
Every feature engineered to protect, perform, and endure at 5-person scale — whatever the weather.

Powerful Heat for Larger Spaces
9kW FERO Heater — Built to Fill a Bigger Cabin
To match the increased capacity, the C2 5 Person is equipped with a 9kW freestanding Kohler FERO electric sauna heater — delivering strong, consistent heat throughout the entire cabin even in colder outdoor ambient temperatures. Sauna stones and a heater guard are included for both performance and safety.
9kW output — sized for 5-person outdoor performance
Sauna stones included for authentic heat
Protective heater guard for safety
Dual thermostatic controls for stable, repeatable heat
A larger cabin demands a more powerful heater. At 9kW, the FERO delivers consistent, enveloping heat across the full 5-person interior — performing reliably in cold outdoor conditions where lesser heaters would struggle to maintain temperature.
Kohler FERO 9kW Electric Heater System
Precise Control
Full Command from Outside the Cabin
The external digital control panel gives you precise control over temperature, session duration, and interior lighting before you step inside — no adjustments needed mid-session. Dual thermostatic controls maintain stable, repeatable performance even during extended multi-user sessions outdoors.
Inside, 2.1" mineral wool insulation and a rubber sealing system retain heat efficiently across the larger space, while the Aerotherm ventilation system ensures consistent airflow and oxygen exchange throughout.
Efficiency Without Compromise
Insulation, sealing, and ventilation working at scale — reliable heating performance even in demanding outdoor environments.
