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!

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.

Spacious interior

Boasting an interior of 150 - 250 cubic feet, Thermory Barrel Saunas give you nearly 50% more room than other barrel saunas. And, with two diameters of over six or seven feet respectively, you can make taller friends.

Easy Assembly

We pride ourselves on our attention to detail—right down to our installation guide. Your Thermory barrel sauna comes with pre-cut and pre-milled staves and cradles, so there’s no cutting necessary. And if you choose an electric heater, you’ll need a 240 volt line and an electrician to finish the job.
