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.

  • Spacious 6.06-foot inside diameter with 19.5-inch-deep Thermo-Aspen benches for your ultimate sauna bathing comfort
  • Sustainably sourced Northern European spruce features a brushed texture, distinct knots, and consistent heartwood color
  • Chemical-free thermal modification naturally enhances every board to its core
  • Unrivaled rot- and moisture-resistance with exceptional stability and durability
  • Superior insulating properties keep you surrounded with even heat distribution
  • Intuitively engineered for simple DIY installation
  • Install in one day with no cutting required
  • Rain jacket, flooring, and exterior trim package included
  • Up to 4 person sauna
  • 124.3 cu. ft.
  • Install the sauna heater of your choice


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.

Features :

All-weather protection

Your Thermory Barrel Sauna’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.
Extra-wide window

No matter what’s outside—rain, snow, jealous neighbors—enjoy the view through your barrel sauna’s dramatic, half-moon-shaped window.
Thermal modification

Thermal modification preserves the beauty of real wood, enhancing it naturally with only heat and steam for unequaled durability and stability—even in changing weather conditions. Plus, no hot feet!
Spacious interior

Boasting an interior of nearly 250 cubic feet, Thermory Barrel Saunas give you nearly 50% more room than other barrel saunas. And, with a diameter of more than seven feet, you can make taller friends.
Bold design

Blending rustic charm with modern European details, your Thermory Barrel Sauna transforms gorgeous Nordic softwood into an extraordinary space to relax and indulge. Some days, you’ll just stare at it.
Heating options

HUUM heaters are the perfect complement to our barrel saunas due to our shared passion for quality and precision. With their minimalist design and high stone capacity, HUUM heaters give you long-lasting heat and steam. And your sauna’s curved interior ensures even heat distribution, so nobody fights for the “good seat.”
Color transformation

The color of Thermory Nordic spruce transforms into a distinguished silver when exposed to sunlight and rain. But if you’re not ready to go gray, simply treat the boards with a penetrating UV protective oil.
