Smart shape. Sweeping views.
Nordic spruce gets a fresh look in a square silhouette with curved contours. Take in the view from the full tempered-glass front of your Thermory Sauna Square while you rest your feet on the tiered bench. Go ahead, stay awhile.

The most spacious
The height and width of our squares give you seven feet of headroom and deep benches to sit or fully recline.

The most durable
Thermally modified Nordic spruce never shrinks for unmatched durability and stability, along with 25 years of proven rot resistance.

The most comfortable
Unlike cedar, which can become rough, our Nordic softwood is milled to give you the smoothest surface that’s never too hot.
Take the next step
Thermory Saunas are the only thermally modified saunas in North America. So, you get the beauty of real wood, naturally enhanced with only heat and steam for unequaled durability and stability. And your sauna never shrinks—even in changing weather conditions. Cedar can’t say that.


Sitting porch
Your Thermory Sauna Square’s porch is the perfect place to take breaks between sessions. It’s also a good spot to leave your shoes, your robe, and your troubles.
Tiered bench
When you entertain in your Thermory Sauna Square, there’s never a bad seat in the house. Plus, you can rest your feet on the convenient lower bench.


Extra-wide Window
No matter what’s outside—rain, snow, or jealous neighbors—enjoy the view through your Thermory Sauna Square’s dramatic, rectangular window.
