Thermory Saunas

Thermory’s saunas stand apart as the only thermally modified models available in North America—crafted using only heat and steam to enhance real wood for superior durability, stability, and resistance to shrinkage. Thicker staves contribute to solid construction, excellent heat retention, and a quieter interior environment.

Built for long-term use, each sauna features keystone staves that encourage water runoff and prevent moisture buildup—ensuring dependable rot resistance over time. The Nordic spruce exterior naturally ages to a beautiful silver patina when left untreated, or can be preserved in its original tone with a simple UV-protective finish, giving you flexibility without compromising the integrity of the material.
