The interior walls feature tongue-and-groove Scandinavian spruce paneling for a clean, seamless finish. An Obeche wood bench and matching backrest provide comfortable seating during sessions.
FERO Electric Heater with Sauna Stones

2.1-Inch Mineral Wool Insulation
Thick mineral wool insulation between the walls, combined with 0.3-inch tempered glass windows and rubber seals, minimizes heat loss and maintains stable interior temperatures.
Aerotherm Ventilation System
The Aerotherm system manages continuous air exchange, ensuring a steady supply of fresh oxygen throughout each session without compromising heat retention.
External Digital Control Panel
An external digital display allows precise control of temperature, session time, and lighting. The panel includes a locking cover to protect against weather and unauthorized access.
2700K Warm White Indirect Lighting
Warm white indirect lighting behind the backrest and exterior surround lighting create a calm, inviting atmosphere inside and outside the cabin.
