ThermaSol Solaris Sauna Cabin
Fully Assembled Outdoor Sauna, Solar-Powered, 2 to 5 Person
ThermaSol Solaris Sauna Cabin
Overview
Experience a breakthrough in sustainable outdoor wellness with the ThermaSol Solaris Sauna Cabin, which operates entirely without a power connection for environmentally conscious bathing enthusiasts.
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.

Install on a firm, level surface with slight runoff for drainage (concrete, decking, pavers, or compacted gravel), with a clear, accessible path from the delivery point. A licensed electrician must connect the heater. See the product manual for full guidelines.

Shipping, Warranty & Returns
Shipping & Delivery
Free shipping on all orders within the contiguous United States (lower 48). We do not ship to Alaska, Hawaii, Puerto Rico, U.S. territories, or internationally.
Saunas are made-to-order and typically ship within 1–2 weeks (some models up to 3–4 weeks with customization). Large units ship via LTL freight on a pallet or crate. Freight delivery is curbside — the driver brings it to the end of your driveway or curb and is not obligated to unpack or move it onto your property.
Transit is roughly 3–7 business days (East Coast) or 7–10 business days (West Coast) after shipment. Inspect before signing and note any damage; report concealed damage within 5 days. Questions: shipping@saunacompanyusa.com · 856-426-8530.
Warranty Coverage
Each ThermaSol sauna is backed by a 1-Year Limited Warranty against manufacturer defects in materials and workmanship under normal residential use, beginning on the delivery date to the original purchaser. Valid claims receive replacement parts at no cost.
Accessories are not covered. Sauna Co. handles warranty claims directly — submit a claim through our contact page.
Returns & Refunds
Due to the custom-built and handcrafted nature of our products, we maintain a strict no-return policy. We do not accept returns for change of mind, buyer's remorse, or unsuitability after delivery — even for unopened or unused items.
Used, installed, assembled, or tested products; custom or special-order items (size, finish, accessories); and clearance / open-box / final-sale items are not returnable. The only exception is a qualifying manufacturer defect under warranty. Questions before ordering: info@saunacompanyusa.com.
Installation & Assembly
Freight deliveries are curbside only — the driver will not unpack or carry items indoors. You are responsible for moving the product from curbside and for any assembly. Please arrange help or local movers for delivery day if needed.
White Glove or inside delivery (and, where available, assembly) can be arranged before shipment for an additional charge. Ensure the freight truck can access your location and that the path to the install site is clear.
Financing Options
Payment is made at the time of order via the methods we offer — major credit cards, PayPal, and financing partners. Payment processing is handled securely by our third-party processors.
All prices are in U.S. dollars; applicable sales tax is calculated at checkout. Tax-exempt? Provide documentation prior to purchase. Questions: info@saunacompanyusa.com · 856-426-8530.
