Thermo Black 220 Indoor Sauna

The Thermo Black 220 Indoor Sauna embodies Finnish design through clean lines, functional comfort, and understated elegance. Made from thermally treated poplar, it offers a warm feel, natural wood aroma, and excellent thermal performance.

Designed for up to three people, it features a balanced interior and black waxed poplar benches that contrast subtly with the light thermowood walls. Its modular construction allows for easy assembly, while solid insulation ensures efficient heating and long-term reliability.
