PROSAUNAS Thermo-Aspen 1×2 INSIDE CORNER TRIM SI is a high-quality sauna cove moulding designed for finishing internal corners with precision and subtle detail. Its curved SI profile softens sharp angles, creating smooth transitions while enhancing the overall appearance of the sauna interior.
Thermally modified Aspen delivers improved durability and dimensional stability, making it ideal for demanding sauna conditions. The heat treatment process reduces moisture movement and enriches the wood’s natural tone, ensuring consistent performance in high heat and humidity.
Each piece is carefully machined for accurate sizing and straightforward installation. The smooth, rounded profile provides a refined look while also ensuring safe, comfortable handling during fitting.
PROSAUNAS uses selected Aspen to maintain uniform colour, fine texture, and reliable long-term performance. This makes it a dependable option for detailed finishing in both residential and commercial sauna interiors.

Read their reviews where they can't curate them, Trustpilot, not their own widget; read the one-star reviews and watch how they respond when freight goes sideways. You can see our Trustpilot reviews here
Ask what happens when a unit arrives damaged, you're listening for a person who owns it, not store-blames-manufacturer ping-pong.
Get the delivered price in writing before payment, "freight quoted after purchase" is the oldest move in the category.
Ask for a name, if nobody owns your order, nobody owns your problem.
