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.

Shipping

PROSAUNAS wood varies in length, weight, and dimension and qualifies for flat rate shipping to the contiguous United States. Freight quotes can be provided for shipments to Canada, Alaska, and Hawaii.   

Flat Rate Freight (boards up to 8’ in length): Wooden materials up to 8’ in length and under 40 pieces, can generally ship Fed-Ex ground, securely packaged in cardboard. Wooden materials up to 8’ in length and over 40 pieces, can ship LTL-liftgate, securely packaged on a custom-made wooden pallet/skid. Board quantity, profile, length, weight, and order composition will dictate the best method of transportation. Wood only orders to the contiguous United States follow the shipping schedule below. Note: On occasion, remote delivery areas may not qualify for these rates. It is strongly suggested that delivery areas be discussed with clients to understand concerns with receiving truck shipments as delivery complexities can complicate transportation timelines and result in increases in flat-rate shipping costs.  

Under 19 boards - $195.00   

20-39 boards - $395.00   

40-99 boards - $495.00   

100-299 boards - $695.00   

300-499 boards - $895.00   

500-799 boards - $995.00   

800-999 boards - $1,295.00  

IMPORTANT About Wooden Material Shipments:

  1. It should be noted that we always package materials with the intention of arriving safely and at the least expensive rate.  
  2. The longest board determines the flat-rate freight category.  
  3. Wooden materials over 8’ in length are assessed for significant surcharges as transportation companies give favor to smaller skid shipments over difficult to move larger crates.   
  4. Sauna heaters, doors, or accessories, when combined with wooden material orders, assist in offsetting transportation costs.      

Flat Rate Freight (boards over 8’ and up to 10’ in length): Wooden materials over 8’ and up to 10’ in length ship LTL, securely packaged on a custom-made wooden pallet/skid. Due to the length of this material, shipments with boards over 8’ and up to 10’ in length do not qualify for a liftgate delivery and will require a dock for unloading with machinery or hand offloading at the installation site. Wood only orders to the contiguous United States follow the shipping schedule below. Note: On occasion, remote delivery areas may not qualify for these rates. It is strongly suggested that delivery areas be discussed with clients to understand concerns with receiving truck shipments as delivery complexities can complicate transportation timelines and result in increases in flat-rate shipping costs. There is a standard 1-hour offloading timeframe before additional delivery charges accrue.

Freight Quotes: Email contact@radiantdollhealth.com for larger orders, remote areas (like islands) or shipments to Alaska, Hawaii, or Canada.   

Combination Orders: Wood orders often include sauna heaters, doors, or accessories. Each order is unique and is assessed for the best method of packaging for safe and secure transportation with attention to limiting freight costs. These items will often ship on a secondary wooden skid/pallet for customer convenience during offloading. In most cases, there are transportation cost efficiencies gained when combining multiple items to wood orders.  

About This Delivery: The weight and packaging of most wooden material orders require delivery by special appointment, and on a wooden pallet. The driver is responsible for “curbside delivery only”. Prior to shipping this product, we may contact customers to share shipment details and discuss any extenuating delivery circumstances that may complicate or cause additional delivery expenses. Our goal is to ensure your project’s success.
