ThermaSol Solaris 2-5 Person Fully Assembled Solar-Powered Outdoor Sauna Cabin
Named one of TIME’s Best Inventions of 2025, the ThermaSol Solaris Sauna Cabin is the world’s first fully off-grid, solar-powered outdoor sauna. Designed for wellness enthusiasts who value sustainability, the Solaris operates without a power connection — solar panels mounted on the roof and side wall charge the integrated battery system, with one day of sunlight providing a full charge. Monitor power levels in real time through a dedicated mobile app, bringing complete control to eco-conscious bathers wherever they choose to place the sauna.
Tile Oak cladding covers the exterior and interior for a modern European aesthetic with excellent UV resistance. Inside, brushed alder benches and backrests complement the full-length solar-tinted glass door and expansive alder-framed window, bringing in natural light while preserving daytime privacy. RGB color therapy LEDs create a customizable ambiance, while the Harvia KIP heater delivers powerful, efficient heat through solar energy. Backed by ThermaSol’s 1-year warranty.
