PROSAUNAS Aspen Groove-S 1X3 T&G Wall Cladding – Sauna Wood

Narrow boards, crisp shadow lines, a lot of personality in a small footprint. The Groove-S is a 1×3 tongue-and-groove in natural aspen: 0.59 in thick, 2.4 in wide, 1.9 in of coverage per board, with precision-milled fluted slats that give a wall real visual texture. Aspen means pale, cool, resin-free. This profile means the room looks like a decision was made, not just a box lined with boards. Sold by the linear foot in 1, 5, and 10 ft lengths.

ProSaunas

Three inches wide, and it still manages to have more presence than most 4-inch profiles.

The ProSaunas Aspen Groove-S 1×3 is a narrow tongue-and-groove cladding with a shadow-line reveal that punches above its width. At 0.59 in thick (0.59″) and 2.4 in wide with 1.9 in of coverage, the Groove-S mills a crisp, angular channel between each board. The result on a full wall is a finely fluted surface: tight horizontal lines, a lot of depth, and a look that works equally well in a Japanese-influenced minimal room or a clean Nordic box. Milled in Estonia. Available in 1, 5, and 10 ft lengths, sold by the linear foot.

Why Aspen

Aspen gives you the palest possible tone, which is exactly right for a narrow-slat profile: the shadow lines read clearly against a light background. No resin, no splinters, cool to the touch at temperature. The honest trade-off with natural (non-thermally-modified) aspen is that it moves a bit more through the heat-and-cool cycle than thermo-aspen, which can mean the groove gaps open very slightly over years of use. It sands and refinishes easily if you ever want to refresh the surface. If you run a very hot room very frequently and want minimal movement, look at our thermo-aspen Groove-S.

Where it goes

Walls and ceilings wherever you want a deliberately designed surface rather than a plain lined wall. Particularly strong on a ceiling, a back wall behind the bench, or any accent plane. Mixes well with a simpler STS4 aspen profile on adjacent walls if you want to break up the room visually. Pair with aspen S4SEE bench boards to keep the palette cohesive.
