ThermaSol Fortis Sauna Cabin

ThermaSol Fortis Outdoor Sauna

Modern Design Meets Outdoor Wellness

The ThermaSol Fortis Sauna Cabin combines contemporary architecture with high-quality materials to create a private, light-filled backyard sanctuary. Its modern eave-style roofline provides a subtle overhang while protecting the sauna interior, and the Nordic thermo-spruce and pinewood exterior offers natural textures that blend seamlessly with outdoor surroundings.

Sleek Glass Front and Functional Design

The front façade features 8mm Parsol dark grey glass with hidden aluminum framing, combining style with solar protection. Hidden hinges and integrated coat hooks add utility without compromising the clean, contemporary look. Step inside to experience the warmth of brushed thermo-spruce walls contrasting with smooth thermo-aspen benches and backrests for maximum comfort and durability.

Cozy, Efficient, and Illuminated

Multi-layer wood fiber insulation ensures a cozy, energy-efficient sauna all year round. Integrated RGB LED lighting, recessed throughout the cabin, provides customizable ambiance, controlled via the included remote. The Harvia Virta heater delivers abundant heat and steam, controlled easily via the Harvia Xenio panel, for the perfect year-round sauna session.
