Prosaunas Alder 1x4 STS4 Tongue & Groove Sauna Wall Paneling

Bring contemporary Scandinavian style to your sauna with Prosaunas Alder STS4 1x4 Tongue & Groove wall and ceiling paneling. This profile features narrow, angular grooves that create a modern nickel-gap look, offering bold visual texture while maintaining a clean, refined appearance.

Prosaunas hand-selects premium Alder for its light, even color and subtle grain pattern. Naturally durable and water-resistant, Alder also has low thermal conductivity, making it an excellent material for sauna interiors. It remains comfortable to the touch even in extreme temperatures and does not secrete resin—ideal for long-lasting performance in sauna environments.

The STS4 profile delivers sharp, defined lines and can be combined with other wood finishes to create sophisticated contrast and custom designs. Precision-milled to Prosaunas' exacting standards, this cladding reflects modern craftsmanship rooted in decades of experience.

With over 55 years of sauna design expertise, Prosaunas sources only the finest wood from Northern Europe and Canada, ensuring top-tier quality, consistency, and customer satisfaction in every order.

Note on Lumber Sizes:
Lumber in North America is sold using nominal sizing, based on the dimensions of freshly cut wood. After drying and surfacing, the actual size is slightly smaller. Refer to the size chart or diagram for exact measurements.
