The ThermaSol Solaris Sauna Cabin is the first fully solar-powered, off-grid electric sauna in the U.S.—a blend of modern design and sustainable innovation. Inspired by the Latin words “solis” (sun) and “ars” (art), Solaris brings a luxurious sauna experience to virtually any location with no power hookup required.
Available in Small (2–3 person) and Medium (4–5 person) sizes, Solaris fits beautifully in outdoor settings like backyards, patios, or lakeside getaways. Featuring a solar-tinted panoramic glass wall, durable tile cladding, and a compact Harvia heater, it’s both elegant and built to last. Each unit ships fully assembled with integrated solar panels, battery packs, and the Xenio CX170 digital control system for a seamless experience.
