What makes Thermory Barrel Saunas unique? Ours are the only thermally modified barrel 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 it never shrinks—even in changing weather conditions. It’s the most ideally suited wood for your sauna experience.

We look 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. Your Thermory Barrel Sauna comes with our step-by-step installation guide. And there’s no cutting necessary, thanks to our pre-cut and pre-milled staves and cradles.

A Thermory Barrel Sauna is a unique space to enjoy on your own or share with others. And once you own one, you’ll wonder how you ever got along without it.

Wet, cold, or hot climates, Thermory barrels outperform and outlast them all.

Once you step into a Thermory Barrel Sauna, you escape into your own private sanctuary of heat, steam, and quiet comfort, unmatched by any other barrel. More than a place to shed the burdens of the day, a Thermory Barrel Sauna is your own personal space to speed your body’s natural healing process. Just relax and let your sauna do the work to help rejuvenate sore muscles, improve joint movement, and eliminate built-up toxins. So, whatever the day takes out of you, you’ll always finish strong.

Excellent quality and service

Our sauna arrived within days of our order and assembly was a breeze for the most part. We had considered some other, less expensive saunas but feel very grateful that we went with Northern Saunas. The beauty and quality of materials is so evident, and the customer service has been excellent so far.
