ThermaSol Solaris: an outdoor sauna that runs off grid
The ThermaSol Solaris is a fully assembled outdoor sauna cabin that needs no electrical hookup. Panels on the roof and one wall charge a battery pack. A day of sunshine gives it a full charge, and you can check the power level on a phone app. TIME included it among its Best Inventions of 2025. Inside, you get brushed alder benches and backrests, plus a tinted glass door and large tinted window. The Tile Oak covering inside and out resists UV. It needs a firm, level base, such as concrete, pavers, decking, or compacted gravel.
Choose Small or Medium on the page. The included Harvia KIP 3 kW electric heater comes with stones and a Xenio CX170 Wi-Fi control. You can also add a bucket and ladle, wood care supplies, or temperature and humidity gauges. It is built to order in about 12 weeks and arrives on a flatbed truck. A forklift or crane places it on your base. To get our best price and best discount, request a quote on the page and let us know where you would like it shipped. Want room to expand?
