Thermory

Sauna Marketplace couldn’t be prouder to feature Thermory, a global leader in sustainable wood sourcing and thermal modification, in our catalog of sauna products. As an industry innovator, Thermory has advanced the sauna landscape by harnessing the natural beauty of responsibly sourced woods such as Aspen, Alder, and Nordic Spruce, while championing chemical-free processes to make saunas more durable and beautiful.

In addition to bringing European sauna woods to America (no, they don’t use Cedar in Finland), Thermory has shown that thermally modified wood can be naturally more rot resistant and sustainable than other options.

Using heat and steam naturally enhances the wood’s properties, creating products that set the rot resistance and longevity standard. With a team of expert wood scientists and advanced technology, Thermory achieves precision in every batch processed in their 20,000 square ft. chambers. This meticulous control over the modification process results in remarkable product durability and stability, offering significant resistance to moisture.

It also means you can order a sauna kit from Thermory in Northern Europe and know exactly what it’s going to be when it reaches you. That’s why Thermory sauna kits fit together every time, while cheap Chinese sauna kits will never come together.

Thermory is unique in how every fiber of the wood is altered, right down to its core, through its innovative thermal modification process. The company’s Smooth-Kissed Milling technique also ensures that each board is consistently smooth, straight, and reliable – a testament to Thermory’s refusal to compromise on excellence.

At Sauna Marketplace, we offer a wide range of Thermory products that have consistently proven their quality through third-party testing, including rot resistance, stability, fire safety, strength, and termite resistance. These products include world-renowned thermally treated sauna wood, barrel saunas, doors, and vents. Each of these products showcases the blend of natural beauty and enhanced function that Thermory is famous for.

We are very excited about the new Thermory Squares, aka No 40 and 41 with an awesome layout and tiered L Benches.

And it doesn’t stop there.  Thermory is behind Auroom, the best sauna kits and outdoor preassembled saunas which are now available in North America on SaunaMarketplace.com.

When you choose Thermory products from Sauna Marketplace, you’re investing in more than just a product. You’re choosing a piece of expertly crafted, responsibly sourced wood that balances natural aesthetics with outstanding performance, longevity, and rich color. Trust in Thermory to deliver a sauna experience that is as durable as satisfying.
