Give your sauna a bold, modern edge with 1×4 Alder STS4 wall panels. The STS4 profile features narrow, angular grooves that create a sharp, linear look and can be paired with other profiles for striking contrast.

Alder is a durable, water-repellent wood that stays comfortable to the touch in high heat, with a warm reddish tone and smooth texture—making it ideal for stylish sauna interiors.
