Nordic wood, square lines, room to recline
Thermory designed the Sauna Square for space. It quotes seven feet of headroom and benches deep enough to sit up or fully recline, in thermally modified Nordic wood that never shrinks and carries 25 years of proven rot resistance.
The wood is milled to a smooth surface that stays comfortable against bare skin and never gets too hot, where cedar can turn rough with time. The No. 41 seats 6, with porch benches out front.

A good seat for everyone
The Square pairs a square silhouette with softly curved contours. A full tempered-glass front opens the room to the view, and the lower tier gives everyone a place to rest their feet. When you entertain, there is never a bad seat in the house.

Built to shed water
Every Square is built around a keystone stave at the top and bottom. The remaining staves point upward, which reduces the chance of water getting trapped in the gaps. Thermory rates the result for 25 years of worry-free rot resistance.

Even warmth from wall to wall
Thermory credits the wood with superior insulating properties, and the curved interior spreads the heat evenly, so nobody fights for the good seat. If you choose a HUUM heater, its minimalist design and high stone capacity give you long-lasting heat and steam.
