Rain Jacket
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.

Spacious interior
Thermory Square Saunas are larger than standard barrel saunas. The interior of our most spacious model measures more than seven feet across, giving you plenty of height for standing and deeper benches for lying down.

Thickness And Strength
The staves are thicker than most (if not all) in the barrel sauna market. This contributes to your sauna’s solid construction and overall weight, giving you greater durability and heat retention while minimizing noise from outside your barrel.

Rot Resistance
The saunas are thoughtfully constructed with a keystone stave at the top and bottom. These allow the remaining staves to point upward to reduce the potential of water being trapped in the gaps. So, you get 25 years of worry-free rot resistance.

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.

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

Color Transformation
The color of Thermory Nordic spruce transforms into a distinguished silver when exposed to sunlight and rain. But if you want to preserve your sauna’s natural color, simply treat the boards with a penetrating UV protective oil.
