    Three-path combustion uses about 25% less wood than comparable heaters, but lighting and tending feel like a normal wood stove. Choose 12 or 18 kW for in-sauna loading. Stones, chimney, and required protection are separate.

    PROSAUNAS Thermo-Spruce 1X4 T&G STS4 Wall Cladding – Sauna Wood

    $2.35 per linear footFree samples available

    The most economical real sauna wood we carry, and the traditional one. Natural Nordic Thermo-Spruce, 1×4 smooth tongue-and-groove, the wood Finland has lined saunas with for generations. Light tone, tight characterful knots, a clean mild scent. It is not thermally modified, so it moves a little more than our thermo woods through the heat-and-cool cycle. We carry it for the budget build and the honest Finnish look. Sold by the linear foot, in lengths up to 14 ft.

    PROSAUNAS Thermo-Aspen 1X2 UK Door Trim – Sauna Wood

    $3.15 per linear footFree samples available

    The detail that ties the room together. Thermo-aspen door trim in the UK profile finishes the gap between your cladding and the door frame with the same golden-brown wood you used on the walls. Thin at 0.47″, wide enough at 1.65″ to cover a clean reveal. No resin, no splinters, cool to the touch. Because it’s thermally modified, the color runs all the way through, so a mitered corner or an end cut won’t show pale raw wood. If you’ve gone with thermo-aspen walls and benches, this is the piece that makes it look intentional.

    PROSAUNAS Thermo-Aspen 2X6 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood

    $11.89 per linear footFree samples available

    The bench wood we have the most opinions about. Thermally modified aspen, milled wide at 2×6 so a bench or backrest reads as one clean surface. Aspen doesn’t bleed resin, doesn’t splinter, and sits cool under bare skin even when the room is ripping. The thermal modification (heat and steam, nothing else) takes it to a golden brown and stops the expansion that opens gaps over the years. Aspen is the wood we sell more of than any other, season after season. Pair it with thermo-aspen or thermo-spruce walls for the matched look.

    PROSAUNAS Thermo-Aspen 2X3 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood

    $4.22 per linear footFree samples available

    Narrow bench board, long track record. Thermo-aspen at 2×3 is what most Scandinavian builders reach for when they want a clean, knot-free seat that won’t gap or warp over the years. The thermal modification (heat and steam, nothing else) turns plain aspen into a golden brown that reads as traditional to American eyes, then locks the wood so it can’t hold moisture and won’t move on you. No resin, no splinters, cool under bare skin. Thermo-aspen is the wood we reach for first, and we’d put this board in our own sauna without a second thought. Sold by the linear foot, free samples available. Questions?

    PROSAUNAS Thermo-Spruce 2X4 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood

    $3.88 per linear footFree samples available

    Ben sided his own house in thermo-spruce. That tells you something. This is the 2×4 bench board in thermally modified Nordic spruce, 1.02″ thick by 3.54″ wide, and it’s the budget-friendly bench, backrest, and skirting board. Rich amber color, tight knots, a rustic look that’s not for everybody but that a lot of people flat-out love. The thermal modification (heat and steam, no chemicals) gives it the same moisture resistance and stability you get in thermo-aspen, at a lower entry price. Strong, rot-resistant, and good for benches, backrests, and skirting. The classic move is thermo-spruce walls with thermo-aspen benches. Sold by the linear foot.

    PROSAUNAS Thermo-Aspen 1X2 SI Inside Corner Trim – Sauna Wood

    $1.58 per linear footFree samples available

    Inside corners are where a finish job either looks done or looks almost done. The thermo-aspen SI inside corner trim, 0.55″ thick by 1.18″ wide, fits into the 90-degree seam where two cladded walls meet and gives you a clean, furniture-quality line instead of a butt joint. The thermal modification means the golden-brown color runs all the way through, so a cross-cut end won’t show pale raw wood. No resin, no splinters. Match it to your thermo-aspen walls and benches and the room reads as one continuous material. Sold by the linear foot.

    An outside corner with no raw edge showing. The thermo-aspen VA outside corner trim, 1.1″ on both faces, wraps the 90-degree exterior angle where two cladded walls meet and gives you a clean, mitered line in matching wood. Thermally modified aspen, so the golden-brown color runs all the way through, cut ends look the same as the face, and the piece won’t swell or bow in a wet sauna environment. No resin, no splinters. If you have a sauna room with an exterior corner (a bump-out, a partition, a two-room build), this is what goes there. Sold by the linear foot.

    You won’t find this profile from most mills. Grace is a wide-grooved designer tongue-and-groove, 1.1 in thick and 2.5 in wide, with a 2.2 in coverage and a shadow reveal that reads architectural rather than just “sauna wall.” It’s aspen, so the tone is pale, the surface is resin-free and smooth, and the room stays bright. We carry Grace because when a customer wants a contemporary room that looks considered, not just lined, this is what gets them there. Sold by the linear foot in lengths from 1 to 10 ft.

    PROSAUNAS Aspen 2X2 S4SEE SHP Moulding & Trim – Sauna Wood

    $3.20 per linear footFree samples available

    1.1 in square, eased edges, four smooth faces. The aspen 2×2 S4SEE moulding is the heavier finishing piece: thicker than the 1×1 at 1.1″ square, with enough visual presence to anchor a ceiling line or a bench-frame transition. Same pale natural aspen as the cladding, so it blends rather than competes. The detail that separates a lined room from a finished room is usually this piece, or its absence. Sold by the linear foot in 1 and 10 ft lengths at $3.60/lf, milled in Estonia.

    Outside corners on a sauna wall are a small detail with a noticeable finish impact. The aspen 2×2 VA outside corner trim wraps the convex corner where two clad surfaces meet on the exterior angle: 1.1 in on both faces, in pale natural aspen that matches the wall boards. It gives the corner a finished look and protects the raw edge of the cladding at the same time. Sold by the linear foot in 1 and 10 ft lengths at $3.07/lf, milled in Estonia.

    PROSAUNAS Aspen 1X2 UK Door Trim – Sauna Wood

    $3.07 per linear footFree samples available

    Every clad sauna room has a door, and the door surround is where the cladding either reads finished or reads unfinished. This is the ProSaunas aspen 1×2 UK door trim: 0.47 in thick, 1.7 in wide, in natural aspen that matches the wall boards. It wraps the door opening cleanly and covers the raw edge of the cladding at the reveal. Aspen stays cool, has no resin, and takes paint or a clear finish equally well.

    PROSAUNAS Alder 2X2 VA Outside Corner Trim – Sauna Wood

    $3.07 per linear footFree samples available

    Outside corners are the exposed edges, which means they’re what people see and touch first. This is the alder VA outside corner trim: 1.1" square (1.1 in x 1.1 in), angle-molded to wrap outside corners cleanly in natural alder. Same warm reddish-brown tone as the rest of the ProSaunas alder family, milled in Estonia, E1 certified. Beefier than the inside corner piece at the same 1.1" section, which makes sense: outside corners take contact. At $3.07 per linear foot it finishes the room where the finish matters most. Sold by the linear foot in 1 and 8 ft lengths.

This is the piece that makes the transition from framing to cladding look intentional. Warm reddish-brown alder tone, fine grain, E1 certified. Water-repellent and cool to the touch. It’s a finishing detail, not a structural piece, but a sauna doorway without it reads unfinished. Sold by the linear foot in 1 and 8 ft lengths.
