Those "high quality / great value” saunas flooding Instagram often feature “Thermally Modified Nordic Spruce”—but the reality is far from premium.

Raw Nordic Spruce is shipped to China, lightly processed in a kiln, and milled by the lowest bidder. Kits are then packaged with cheap components like indoor rated fasteners and door hinges. It looks great in photos, but in real conditions it warps, splits, leaks, rusts, molds, and can release harmful fumes from adhesives never meant for high heat. These saunas are not engineered to last outdoors.

Thermory is different.

We mill in the heart of sauna country and set the global standard for thermally modified wood. Our wood is modified in proprietary kilns, through a costly and time-intensive, high-heat process perfected over 30 years. This removes 100% of the moisture and sugars that mold feeds on, and transforms the wood at a molecular level to make it hydrophobic, stable, and exceptionally rot resistant.

Others copy the language, we created the process.

Don't be fooled by pretty pictures and empty promises.

You get what you pay for.

Real value is built to last. Choose Thermory.
