With 25+ years of rot resistance, Thermory saunas are …
The only saunas built to outlive the rest.
“How good is the wood?” If that’s not your first question when shopping for a sauna, you could be making a very expensive mistake.
You may think all saunas are designed to handle heat and humidity. But even the best-looking saunas can show early signs of warping, cupping, and cracking if you don’t start with wood that’s made for extreme conditions.
Thermory saunas are more than just a stunning addition to your home. They all begin with wood that holds up long after others give out.
That’s why people who come to us for their first sauna, end up buying their last.
Why is Thermory different?
All our sauna wood is thermally modified using only heat and steam. It’s not like an exterior finish that wears off over time. This chemical-free process literally bakes durability and dimensional stability into every board for longevity that no other sauna can deliver.
Plus, with rot resistance backed by a 25-year warranty, you’re investing in decades of worry-free performance.
So, don’t build your sauna twice. Build it right—with Thermory.
The highest thermal modification standards
To tell you we naturally enhance our wood based on thermowood industry best practices would be a lie. Because we take our modification recipes and quality control far beyond the average adopted standards.
Our wood scientists have 29 years of experience refining thermal modification technology, monitoring every detail of every batch. This level of consistency and control separates us from those who claim to do what we do.
It might seem obsessive. But it’s the only way to give you sauna kits and building materials that last for more than a quarter century.

Thermory offers the industry’s most complete range of saunas that include barrel saunas, square saunas, insulated cabin saunas, and bespoke modular saunas.
