The Kohler C1 Indoor Sauna features a premium Scandinavian spruce wood interior and Graphite Grey exterior that creates a warm, inviting, and modern sauna environment. Designed for both comfort and performance, this indoor sauna delivers a traditional experience enhanced with high-quality materials and advanced engineering.

Premium Comfort & Design

The interior includes an obeche wood bench and matching backrest, designed to provide lasting comfort during every session. A 2700K warm white indirect lighting system positioned behind the backrest creates a soft, relaxing atmosphere. The tempered glass door and windows enhance visibility while maintaining durability and a clean, modern look.

Mineral wool insulation combined with rubber seals provides excellent heat retention, helping maintain consistent temperatures for an efficient and comfortable sauna experience.

The Kohler C1 Indoor Sauna includes a freestanding FERO electric sauna heater, along with sauna stones and a heater guard for safe operation. A digital control panel mounted externally allows easy control of temperature, session time, and backrest lighting.

Dual thermostatic controls ensure safe and consistent heating, while the Aerotherm ventilation system provides proper airflow, oxygen supply, and air exchange throughout the sauna session.
