Expert help that stays with you

Small details become expensive problems once installation begins. We ask the questions early, so a mismatched part, an overlooked requirement or an installation issue gets caught while it is still easy to fix.

We want you to feel good about choosing Sauna Marketplace long after your first session, and confident recommending us to a friend. That standard guides the advice we give, the products we sell, and the way we take care of our customers.

PROSAUNAS Aspen 3X3 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood

2.7 in square, surfaced smooth on all four sides. The aspen 3×3 S4SEE is a bench board that’s a true square in cross-section: 2.68″ thick and 2.68″ wide. That’s the profile for a chunky, solid-looking bench deck or a structural backrest leg. Aspen, so it’s pale, cool to the touch, and resin-free. The square stock also works as a bench support rail where you want the wood exposed, not hidden. Sold by the linear foot in 1 and 8 ft lengths at $11.62/lf, milled in Estonia.

Square stock gets underused in sauna interiors. It shouldn’t.

The ProSaunas Aspen 3×3 S4SEE is a bench board milled to a true 2.7 in x 2.7 in square (2.68″ x 2.68″), surfaced smooth on all four faces with eased edges. At that cross-section it’s thick enough to stand up as structural bench support without additional framing behind it, or to use as a chunky bench deck board where you want depth and presence rather than a slim slat profile. The aspen is straight-grained, pale, and consistent in color board to board. Milled in Estonia. Sold by the linear foot in 1 and 8 ft lengths.

Why Aspen

At 2.7 in square, the board has a lot of surface in contact with the body. Aspen’s low thermal conductivity means it doesn’t get hot to the touch even when the room is running at full temperature. No resin, no splinters, no aromatic compounds that can irritate sensitive skin. The pale color keeps a room feeling open even with the heavier visual weight of square stock. One honest note: natural aspen is the softest wood in our bench lineup. At 2.7 in thick the board is strong, but the surface face will scratch more readily than thermo-aspen or alder. A quick sand refreshes it fine. If you want a harder surface, the thermo-aspen 3×3 is the alternative.
