Traditional Sauna Heat
A FERO electric sauna heater with sauna stones provides traditional sauna heat. The heater works with dual thermostatic controls for consistent operation, while an externally mounted digital control panel provides convenient adjustment of temperature, session time and lighting.
Heater and electrical specifications vary by model and should be confirmed for the exact configuration selected.
Graphite Gray Exterior
The Graphite Gray exterior gives this C1 a distinctly modern architectural appearance while maintaining the warmth of natural wood inside.
The cabin incorporates tongue-and-groove construction, substantial mineral-wool insulation, rubber seals and tempered-glass elements designed to retain heat efficiently during operation.
Scandinavian Spruce Interior
Inside, Scandinavian Spruce creates a warm, natural environment complemented by Obeche wood seating and backrests.
Integrated 2700K warm-white indirect lighting provides subtle illumination behind the seating and enhances the natural character of the interior.
Aerotherm Ventilation
KOHLER's Aerotherm ventilation system is engineered to provide appropriate air exchange within the sauna cabin during operation, helping maintain comfortable airflow throughout each session.
