Why Thermory?

Thermory are the only thermally modified barrel saunas in North America (hence the name). So you get the beauty of real wood, naturally enhanced with only heat and steam for unequaled durability and stability. And it never shrinks—even in changing weather conditions. It’s the most ideally suited wood for your sauna experience.


Thermally Modified   Sustainable   Weather Resistant    Rot Resistant



The Right Wood : Thermory looks no further than the birthplace of sauna culture for beautiful Nordic softwood to craft your Thermory Barrel Sauna. Unlike cedar, which can become rough and unattractive over time, Thermory Nordic spruce’s proven rot resistance and ability to withstand the elements create the perfect marriage between outstanding design and structural integrity.


The Right Way: Thermory’s Nordic spruce is harvested exclusively in Scandinavia, a region celebrated for its responsible forestry practices. And wood is the only naturally renewable building material that doesn’t generate hazardous waste. So when you choose a Thermory Barrel Sauna you’re investing in the health of our planet. That’s why their mission is to “leave a lasting impact.”

Thermory Barrel Sauna 50 Series are larger than standard barrel saunas. With a diameter of more than six feet, the spacious interior offers a greater height for standing and deeper benches for laying down. Plus, thermal modification ensures the wood is never too hot to stand or sit on.

Thermory pride’s itself on it’s attention to detail—right down to their installation guide. Your Thermory barrel sauna comes with pre-cut and pre-milled staves and cradles, so there’s no cutting necessary. And if you choose an electric heater, you’ll need a 240 volt line and an electrician to finish the job.
