The Thermory Sauna Square is a modern outdoor sauna with a distinctive cube shape and a full tempered-glass front that creates an open and scenic experience. Made from thermally modified Nordic spruce, it is built to resist shrinking, warping, and rot for long-lasting durability while staying smooth and comfortable under heat. The interior is spacious with tall ceilings and deep benches for sitting or reclining, and thick construction improves heat retention and reduces outside noise. Additional features like a front porch, large viewing window, and all-weather protection make it both a functional wellness space and an attractive backyard focal point.

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.


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.

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

Your Thermory Sauna Square’s thermally modified wood is built to withstand the elements for up to 25 years. But if you want to baby this beauty, the rain jacket is included for coverage in wet weather.

FREQUENTLY ASKED QUESTIONS

What sauna is best for my home and lifestyle?

What sauna is best for my home and lifestyle?

The best sauna for your home and lifestyle depends on your space, how you plan to use it, and your preferred look. Barrel saunas are great for smaller spaces and a classic outdoor feel, with efficient heat circulation. Square saunas offer more interior space, higher ceilings, and a more open, comfortable layout. Mod-6 saunas provide the most premium experience, with full insulation, flexible bench layouts, and room for larger groups or activities like stretching or entertaining. Our team of experts can help assist you in picking the perfect model for your space and lifestyle.
