ProSaunas Thermo-Aspen 1x1 S4SEE Trim with eased edges offers an elegant way to define and elevate the look of your sauna with a furniture-quality finish. This material is exceptionally well-suited for sauna environments, as it does not secrete resin, splinter, or become uncomfortably hot. Its golden-brown tone and smooth texture bring warmth and sophistication to any sauna design.

The thermal modification process—an organic treatment using heat, steam, and pressure—enhances the wood’s performance by improving dimensional stability, water resistance, and overall durability. Thermo-Aspen is naturally resistant to decay, pests, and fungi, making it a superior alternative to untreated wood.

ProSaunas selects only the finest wood from Northern Europe and Canada, ensuring consistent quality and appearance. With over 55 years of experience crafting premium sauna rooms across North America, Prosaunas maintains the highest standards to guarantee your complete satisfaction.

Please note: In North America, wood sizes are provided in nominal measurements, which may differ slightly from actual dimensions due to drying and surfacing processes. Refer to our diagram for precise measurements.
