Combining contemporary architecture with robust materials, the Fortis Sauna Cabin is a private, light-filled wellness sanctuary.
The Fortis is highlighted by the modern, eave-style roofline offering a slight overhang which encapsulates the sauna interior. The Tyrol Wood exterior features unique natural textures accentuated by inset black trim, a stark contrast with the tinted glass front. Parsol argon insulated glass offers UV-protection on the front-facing facade, with hidden hinges and coat hooks providing sleek styling and utility.
Inside, the Fortis hosts multi-layer wood fiber insulation to keep the interior cozy and energy efficient year-round. Tyrol wood walls offer a warm, textural contrast in comparison to the sleek thermo-aspen benches and backrests. Full-spectrum LED illumination from recessed locations compliments the inviting atmosphere, with an included control to perfect the desired ambiance. Bathing enthusiasts can sit back and enjoy the Harvia Virta's abundant heat and steam operated through the Harvia Xenio control for year-round sauna sessions.
Supported by a 1-year warranty, the ThermaSol Fortis outdoor sauna delivers powerful performance and refined wellness in a modern, contemporary space.
