Thermory Sauna Lumber

Wall Panels, Bench Boards & Sauna Materials

At Bsaunas, we carry a wide selection of Thermory sauna lumber designed specifically for walls, benches, and finishing materials. Whether you choose natural woods like Alder and Aspen or thermally modified Thermowood such as Thermo-Aspen, Thermo-Magnolia, and Thermo-Spruce, every piece is crafted to perform in the high heat and humidity of a sauna. Smooth, chemical-free, and long-lasting, Thermory wood ensures comfort, beauty, and reliability in every sauna build.

Thermory wall panels create a smooth, elegant finish for sauna walls and ceilings. Available in both natural woods (Alder, Aspen) and thermally modified options (Thermo-Aspen, Thermo-Spruce, Thermo-Magnolia), these panels combine beauty with durability. Light natural tones give a clean, modern feel, while dark Thermowood options provide a rich, luxurious look. Every panel is chemical-free, dimensionally stable, and designed to perform in extreme heat and humidity.

Built for comfort and long life, Thermory bench boards stay smooth and splinter-free, even after years of use. Natural Alder and Aspen offer a light, knot-free surface that stays comfortable to sit on at high heat, while Thermo-Aspen delivers added durability, resistance to warping, and a deep, warm tone. Whether you want a clean Scandinavian look or the rich color of Thermowood, Thermory bench boards ensure comfort and strength for any sauna.

The finishing touches make all the difference. Thermory offers high-quality sauna mouldings and ventilation covers crafted from the same premium woods as the panels and benches. These details ensure a consistent look throughout your sauna, while also improving function and airflow. With Thermory sauna materials, you can achieve a professional, polished finish that matches perfectly with your chosen wall panels and bench boards.

Why Thermowood Stands Out

Durability – Resistant to rot, decay, and pests with a service life of 25+ years.
Stability – Won’t warp, swell, or shrink under sauna heat and humidity.
Eco-Friendly – Modified with only heat and steam, sustainably sourced, and toxin-free.
Low Maintenance – No need for constant sealing or staining.
Comfort & Beauty – Smooth, splinter-free, with rich natural tones.

Thermory Thermowood is the ultimate choice for sauna walls, ceilings, and benches—combining beauty, comfort, and unmatched durability.
