A Legacy of Innovation. A Future Rooted in Wellness.
For more than 60 years, Thermasol has led the way in steam and sauna innovation—pushing boundaries in technology, design, and user experience. Trusted by homeowners, designers, and hospitality professionals alike, we’ve transformed the concept of daily rituals into elevated, immersive wellness experiences.
Built on a foundation of craftsmanship and cutting-edge engineering, every Thermasol product is designed for comfort, reliability, and long-term performance—whether it’s a steam shower, smart control, or complete sauna environment.

In 2024, Thermasol proudly joined the Harvia portfolio of wellness brands, alongside Almost Heaven Saunas, EOS, and Harvia—the world’s leading sauna and spa company. Founded in Finland in 1950, Harvia has grown into a global authority in sauna innovation, delivering high-performance solutions in over 80 countries.

This partnership marks a new chapter for Thermasol—uniting American innovation with Finnish sauna tradition. Many of our saunas now feature the time-tested power of Harvia heaters, combining advanced performance with decades of wellness expertise.

Together, Thermasol and Harvia are shaping the future of personal wellness—one experience at a time.
