Thermasol
The residential steam pioneer, now building luxury saunas.
What they're known for
America's home-steam authority since 1958 — now bringing the same spa-grade engineering to glass-front saunas.
ThermaSol helped invent the residential steam shower in 1958 and spent the next six decades as the name behind spa-grade steam in American homes — generators, SteamVection heads, and the digital controls that turn a bathroom into a steam room. The sauna line is the natural extension of that wellness-engineering culture, pointed at dry heat instead of vapor.
The Nordic Misty collection brings the sensibility to the cabin: panoramic glass fronts, thermally modified aspen benches, brushed Tyrol wood interiors, RGB chromotherapy lighting, and Harvia Virta heaters with Wi-Fi control. Indoor models like Lumaria and enclosed outdoor units like Fortis are delivered through ThermaSol's dealer and pro network rather than drop-shipped in a crate, placing the brand at the design-forward, professionally installed end of the home sauna market.
