Thermasol Solaris - Tile Oak, 2-5 Person, Solar-Powered Outdoor Sauna

Solaris is the world’s first fully off-grid, solar-powered sauna in the U.S.—a radiant blend of design, innovation, and sustainability. Inspired by “Solis” (sun) and “Ars” (art), Solaris delivers a full sauna experience anywhere, no power connection required.

Available in two sizes—Small (2–3 person) and Medium (4–5 person)—Solaris fits a variety of outdoor spaces, from cozy patios to lakeside retreats. With integrated solar panels, battery packs, and a pre-installed electric heater, it offers either full solar-powered autonomy or a low-energy model with reduced power needs.

The solar-tinted panoramic glass wall invites in natural light while preserving privacy. Inside, brushed alder benches and large, tiled surfaces reflect modern European style and are easy to maintain. The durable exterior tile cladding is UV-resistant and built to withstand the elements.

A compact Harvia Delta 3.6 kW heater ensures fast, gentle steam, supported by efficient insulation. LED lighting and heater controls are integrated into the Xenio CX170 panel for a seamless experience.
