THERMASOL SOLARIS FULLY ASSEMBLED OUTDOOR SAUNA, SOLAR POWERED, 2-5 PERSONS
Recognized by TIME as one of the Best Inventions of 2025, the Solaris Sauna Cabin is a fully off-grid, solar-powered sauna that works wherever the sun shines.
A fusion of sustainability and wellness, the Solaris delivers a complete sauna experience with the flexibility of no required power connection. The contemporary design uses Tile Oak cladding on both the exterior and interior for a modern European look that is UV-resistant. Solar panels adorn the roof and one external wall with one day of sunshine needed for a full charge, and the ability to monitor power levels through a mobile app.
Enter through the full-length glass door and step into the well-insulated sauna cabin highlighted by an expansive glass window with alder framing. Both pieces of glass are solar tinted to bring in natural light while maintaining privacy during daytime sauna sessions. RGB color therapy LEDs glow from recessed locations throughout the cabin, with the included control able to fully customize users' desired ambiance. Lie back upon brushed alder sauna benches and backrests while the Harvia KIP delivers gentle heat and restorative steam through solar power.
Supported by ThermaSol's 1-year warranty, the Solaris outdoor sauna is the first of its kind, offering complete freedom for eco-conscious bathers to experience wellness from anywhere they desire.

Delivery & Assembly:
Shipping costs are determined based on location (e.g. we will send you an invoice to collect this payment). Outdoor saunas are delivered via flatbed trailer and fully assembled.
Customers are notified two weeks prior to the scheduled delivery to allow time for preparation. A forklift or crane is required for placement, and a licensed electrician must install the heater. Due to its size and weight, manual offloading is not recommended. Please ensure the proper equipment is available at the time of delivery.
Please ensure you are fully prepared to receive and unload your sauna in accordance with the instructions provided in your manual.
Site Preparation:
The path from delivery point to placement site must be clear and accessible for equipment. Saunas should be installed on a firm, level surface with slight runoff for drainage—such as concrete, decking, pavers, or compacted gravel.
For complete guidelines, please refer to the product manuals.
