PROSAUNAS Alder 2X6 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood

Wide-board alder bench material, and it reads completely differently than the 2×3. At 5.51" wide (5.5 in), each board is a statement. Same natural alder warmth: reddish-brown, fine grain, a soft honey scent when steam hits it. Milled in Estonia to S4SEE spec, 1.1" thick, eased edges on all four sides. Water-repellent, stays cool under bare skin, E1 certified. If you want a bench or backrest that reads as one clean, warm surface rather than a field of narrow slats, this is your board. Sold by the linear foot in 1, 9, and 10 ft lengths.

“Great communication and service! Really happy with my experience.”

Sam S. · ProSaunas All-Glass Sauna Door owner

“I received our sauna wood order last week and love the product!”

John V. · ProSaunas Thermo-Aspen wall cladding owner

“Excellent response times and customer service.”

Nathan L. · Sauna LED Light Strip owner

“We are so happy with our outdoor sauna!”

Scott P.

“The team at Sauna Marketplace made what could have been a stressful, expensive online purchase feel smooth and manageable. I ordered a SaunaLife EE6G barrel sauna, and they were really helpful through all the back and forth while I figured out the right setup, from the sauna and heater to foundation, electrical, and build questions. I also happen to live near one of the founders, and he actually came by for a couple of hours to help me get started on the build. Seriously above and beyond. I can't recommend them enough.”

Mike M. · About the SaunaLife EE6G

“We're in business! Tested the heating, feels great! Thanks a ton, Ben!!”

R. R. · SaunaLife Model CL3G owner

Three boards of this at 10 feet and you have a backrest that looks like it came out of a sauna in Helsinki. That’s the point of a wide bench board: fewer seams, cleaner surface, the wood does the talking. This is natural alder, 5.51" wide, and it’s our widest alder bench board.

S4SEE means surfaced four sides with eased edges: smooth face, no sharp corners at the edges, ready to sit on. The 1.1" thickness gives it good feel underhand. At $10.68 per linear foot, it’s still well under what comparable clear cedar runs at width. Milled by ProSaunas in Estonia from natural alder certified to E1 emissions standards.

Why Alder

Alder has been the go-to Finnish bench wood for generations for a reason: it stays cool, it doesn’t secrete resin, and the warm reddish-brown tone ages gracefully. Fine, even grain, thermal conductivity around 0.12 W/m·K, a pleasant honey-like aroma when the room gets hot. The honest limitation here is the same as with any natural alder: it’s soft, and it will scratch. Heavy use shows over time. If durability under hard use is your main concern, look at thermally modified options. For a classic Finnish room where the look matters as much as the function, alder is the classic call.

Where it goes

Benches and backrests where you want wide, clean boards. Combine with the 2×3 for a tiered bench with visual contrast. The alder Grace wall cladding pairs naturally with this for a matched room. Also works as floor boarding, though wear will show faster there than on benches.
