Sweeping Views, Unmatched Spaciousness

Spacious Interior: Enjoy the luxury of space with over seven feet of headroom and deep benches that invite you to sit back or fully recline.  If you’re looking for a versatile sauna that can serve as a yoga room or quiet retreat, this is it.
Tempered-Glass Front: The full tempered-glass front offers panoramic views, ensuring every session is as visually soothing as it is relaxing.
Optional Panoramic Window (Optional): Take in massive views from the front and the back of the Thermory Model 40 (with back windows) or opt for more privacy and coziness with the Thermory Model 41 (without back window)

Superior Durability & Comfort

Thermally Modified Wood: Nordic spruce undergoes thermal modification for unparalleled stability and 25 years of proven rot resistance.  Wood is sourced and modified in Northern Europe where thermal modification has been perfected.
Smooth Surface: Experience the smoothest surface underfoot, crafted from Nordic softwood to ensure comfort without the roughness of cedar.

Eco-Friendly and Sustainable

Sustainable Forestry: Thermory wood is sourced through responsible practices, ensuring no harm to tropical woodlands and rainforests.
Chemical-Free Process: The thermal modification process is entirely natural, using heat and steam to enhance durability without chemicals.

Features & Specifications

Larger Than Standard: Thermory saunas surpass traditional barrel saunas in size, offering more room to stand and recline.
Elevated Climate: Most barrel saunas don’t elevate the bathers’ feet, leaving their lower half in the coldest part of the sauna.  The Tiered Benches in the Sauna Square ensures your entire body will benefit from soft heat and steam.
Rot Resistance: Designed with a keystone stave at the top and bottom to prevent water trapping, ensuring decades of worry-free use.
Color Transformation: The wood naturally ages to a distinguished silver, which can be preserved with UV protective oil.

Comfort and Leisure

Sitting Porch: The perfect spot for breaks between sessions, leaving behind shoes, robes, and troubles.
Extra-Wide Window: Enjoy the view through a dramatic, rectangular window, no matter the weather outside.
All-Weather Protection: Included rain jacket for your sauna ensures it remains pristine in any condition.

Easy Assembly & Installation

No Cutting Necessary: Pre-cut and pre-milled components make assembly straightforward, requiring less than a day with a few friends.

About Thermory
Sauna Marketplace couldn't be prouder to feature Thermory, a global leader in sustainable wood sourcing and thermal modification, in our catalog of sauna products. As an industry innovator, Thermory has advanced the sauna landscape by harnessing the natural beauty of responsibly sourced woods such as Aspen, Alder, and Nordic Spruce, while championing chemical-free processes to make saunas more durable and beautiful. In addition to bringing European sauna woods to America (no, they don't use Cedar in Finland), Thermory has shown that thermally modified wood can be naturally more rot resistant and sustainable than other options. Using heat and steam naturally enhances the wood's properties, creating products that set the rot resistance and longevity standard. With a team of expert wood scientists and advanced technology, Thermory achieves precision in every batch processed in their 20,000 square ft. chambers. This meticulous control over the modification process results in remarkable product durability and stability, offering significant resistance to moisture. It also means you can order a sauna kit from Thermory in Northern Europe and know exactly what it's going to be when it reaches you. That's why Thermory sauna kits fit together every time, while cheap Chinese sauna kits will never come together. Thermory is unique in how every fiber of the wood is altered, right down to its core, through its innovative thermal modification process. The company's Smooth-Kissed Milling technique also ensures that each board is consistently smooth, straight, and reliable - a testament to Thermory's refusal to compromise on excellence. At Sauna Marketplace, we offer a wide range of Thermory products that have consistently proven their quality through third-party testing, including rot resistance, stability, fire safety, strength, and termite resistance. These products include world-renowned thermally treated sauna wood, barrel saunas, doors, and vents. Each of these products showcases the blend of natural beauty and enhanced function that Thermory is famous for. We are very excited about the new Thermory Squares, aka No 40 and 41 with an awesome layout and tiered L Benches.
