Alder 5/4×3 STEP Wall Cladding – Sauna Wood by Thermory
Price range: $3.72 through $145.82Step up your game and build the sauna of your dreams with Alder STEP Cladding by Thermory. The broad, square grooves create a striking shadow effect, adding depth and intrigue to any space. It’s our go-to for vertical wall cladding in any high-end sauna build.
Alder is a popular and timeless sauna wood with natural water repelling properties. It’s a medium tone with reddish tints and a subtle honey-like aroma. At Sauna Marketplace, we make it easy to build an Alder sauna with matching benches, backrests, bench skirts, vent hatches, floor grids, and more.
The actual wall coverage is 2.2″, which completes the step.
PROSAUNAS Round Thermo-Abachi Sauna Ventilation Cover
Price range: $111.20 through $119.20The sauna rabbit hole is real, but this choice is simple: you need intake and exhaust vents. This round PROSAUNAS cover finishes a standard 3.9-inch sauna ventilation duct while its rotating face lets you adjust airflow. Choose natural sanded thermo-abachi or brushed black; both pair well with any sauna wood, blending in or adding intentional contrast. The solid 5.9-inch face is made in Estonia from PEFC-certified wood and moisture-resistant materials and includes a 2-year limited warranty for consumer use.
PROSAUNAS Thermo-Aspen 2X6 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $11.89 through $118.92The 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 Western Red Cedar 1X6 VG S4SEE Bench, Backrest & Skirting – Sauna Wood
Price range: $14.16 through $113.27Wide benches read differently. A 5.44″ board shows less joint, more wood, and the cedar grain has room to do something. This is Western Red Cedar 1×6 VG S4SEE in clear vertical grain, knot-free A+ grade, milled in Canada. At 0.69″ thick, it’s the wider face of our cedar bench line and it makes a single-board backrest or a bench seat with far fewer pieces to install. We waited to carry cedar until we found a clear grade we’d actually put in our own build. The honest note: cedar runs warmer to the touch than aspen at full heat, and it moves more through the heat-and-cool cycle than thermally modified wood. For the classic cedar look at width, this is the board. Sold by the linear foot.
PROSAUNAS Aspen 2X6 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $11.08 through $110.87Wide bench board, pale aspen, eased edges. The 2×6 S4SEE is 1.1 in thick and 5.5 in wide: three boards across a standard 18-inch bench deck and you’re done, with almost no slat gaps breaking up the surface. Aspen stays cool to the touch, never bleeds resin, and shows no splintering. We sell more aspen bench wood than any other species. This is the wide version for a clean, uninterrupted bench surface. Sold by the linear foot in 1 and 10 ft lengths at $11.08/lf, milled in Estonia.
PROSAUNAS Alder 2X6 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $10.68 through $106.85Wide-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.
PROSAUNAS Hemlock 2X4 VG S4SEE Bench, Backrest & Skirting – Sauna Wood
Price range: $10.29 through $102.85Thick, pale, and honest about what it is. Hemlock 2×4 VG S4SEE is 1.5″ of clear, knot-free hemlock bench stock, 3.5″ wide, surfaced and eased, milled in Canada. At this thickness the bench edge reads as a real piece of wood, not a veneer. Low resin, even texture, almost no scent. We stock the clear VG grade because it’s the one we’d use. Honest note: hemlock at 1.5″ thick moves more through the heat cycle than thermo-aspen, and over years small gaps can open at the joints. For tight long-term joints, thermo-aspen is a better bet. For a pale, modern bench in clear North American wood, this is a good board. Sold by the linear foot.
PROSAUNAS Thermo-Aspen 3X3 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $11.62 through $92.96Bench legs that don’t need to be babied. The 3×3 thermo-aspen is a glulam engineered bench support, 2.68″ square on both faces, built to carry weight in a wet, hot room for years without moving. Same thermal modification as everything else in our thermo line: heat and steam, no chemicals, golden-brown color that runs all the way through the wood. Strong, stable, and cool to the touch. Order your bench boards and these together and the whole system ships as one delivery. Sold by the linear foot, free samples available.
PROSAUNAS Aspen 3X3 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $11.62 through $92.962.7 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 10 ft lengths at $11.62/lf, milled in Estonia.
PROSAUNAS Alder 3X3 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $11.62 through $92.96The leg of the operation. This is the 3×3 glulam alder bench support, 2.68" square, engineered from natural alder for the structural parts of a sauna bench. Not a finish piece: it’s what holds everything up. Same warm reddish-brown alder, same E1 certification, milled in Estonia. At 2.68" x 2.68", it’s got the cross-section to handle bench loads without flex. Matches the alder bench board family if you want the whole structure in one species. Sold by the linear foot in 1 and 8 ft lengths.
Sauna Foil Radiant Barrier PROSAUNAS 128938 – 48 in × 80 ft Roll | Pure-Aluminum Radiant & Moisture Shield for Saunas, Basements, Crawl Spaces & More
$92.90Building a sauna that feels as good as it looks starts behind the wood. The ProSaunas 48-inch × 80′ (320 sq foot) Vapor Barrier Foil is a pure-aluminum radiant shield and Class I vapor retarder in one, reflecting up to 97 % of radiant heat back into the room while blocking moisture from entering your wall cavity. Each 320 sq ft roll lays flat, tapes tight, and withstands sauna-level temperatures without the bubble-wrap “sag-and-melt” you’ll find at big-box stores. If you’re a DIY homeowner or a pro builder, this heavy-duty foil gives you more even temperatures, lower energy bills, and a structure that lasts. Upgrade your sauna (or any moisture-prone space) with the barrier trusted by serious sauna craftsmen.

PROSAUNAS Western Red Cedar 1/2X4 VG T&G V2E Wall Cladding – Sauna Wood
Price range: $6.15 through $79.87For years we steered people away from cedar. Then a clear vertical-grain run came through worth carrying. This is Western Red Cedar 1/2×4 with a V-joint, knot-free A+ grade, milled for sauna walls and ceilings. It’s the wood Americans picture when they picture a sauna: the warm reddish tone, the aroma that shows up the second the room heats. We carry it for the look-and-smell buyer who wants the classic done right, and we’ll tell you straight where thermo wood holds up better. Sold by the linear foot.
PROSAUNAS Western Red Cedar 1X4 VG S4SEE Bench, Backrest & Skirting – Sauna Wood
Price range: $7.48 through $74.80For years we steered people away from cedar. Then a clear vertical-grain run came through worth carrying. This is Western Red Cedar 1×4 VG S4SEE bench board, knot-free A+ grade, milled in Canada, 0.69″ thick and 3.5″ wide. It’s the bench face the classic sauna crowd wants: warm reddish tone, smooth texture, and that cedar aroma that hits you when the room heats. We waited because modern cedar quality slipped while prices climbed. We carry it now because this grade is actually worth installing. One honest note: cedar runs warmer to the touch than aspen under real heat. If cool skin contact is the priority, aspen benches with cedar walls is a better combo. Sold by the linear foot.
PROSAUNAS Thermo-Aspen 1X5 T&G STS4 Wall Cladding – Sauna Wood
Price range: $6.76 through $67.58A little more width, a little more calm. The 1×5 STS4 in thermo-aspen is a tongue-and-groove board, 0.59″ thick, milled 4.72″ wide for 4.3″ of coverage per row, so the wall reads with fewer seams across a given run.

A clean choice when you want a broad, quiet wall. Sold by the linear foot.

PROSAUNAS Thermo-Aspen 2X4 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $6.15 through $61.45A clean, comfortable bench board in the everyday width. Thermo-aspen milled at 2×4, surfaced on all four sides with eased edges so there is nothing sharp where you sit, 3.54″ wide and 1.1″ thick. Aspen does not bleed resin, does not splinter, and sits cool under bare skin even when the room is hot. The thermal modification, heat and steam and nothing else, takes it to a golden brown and stops the movement that opens gaps over the years. Aspen is the bench wood we sell more of than any other. Sold by the linear foot.
PROSAUNAS Thermo-Aspen Groove-S 1X3 T&G Wall Cladding – Sauna Wood
Price range: $5.98 through $59.84Narrow boards, strong lines, a wall that looks expensive. The Groove-S in thermo-aspen is a precision-milled 1×3 T&G cladding, 0.59″ thick, with a tight shadow groove that turns an ordinary sauna wall into something with real visual snap. At 2.1″ coverage per board, you get a lot of linear rhythm per square foot. The thermo-aspen color, warm golden-brown, runs all the way through, so trimmed ends match the face and nothing reads as patchwork. Knot-free, no resin, stays cool. Pairs well with thicker profiles as a contrast element. Sold by the linear foot.
PROSAUNAS Aspen Groove-S 1X3 T&G Wall Cladding – Sauna Wood
Price range: $5.87 through $58.77Narrow 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 Thermo-Spruce 2X6 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $5.87 through $58.73Ben sided his own house in thermo-spruce. That tells you something. This is the 2×6 bench board in thermally modified Nordic spruce, 1.02″ thick by 5.51″ wide, and it’s the classic budget build starting point. 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 and floors. The classic move is thermo-spruce walls with thermo-aspen benches. Sold by the linear foot.
PROSAUNAS Alder 2X4 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $5.24 through $52.36PROSAUNAS Hemlock 1X6 VG S4SEE Bench, Backrest & Skirting – Sauna Wood
Price range: $7.48 through $52.36Six inches of pale, clear hemlock bench board. This is Hemlock 1×6 VG S4SEE: 0.69″ thick, 5.44″ wide, clear A+ grade, straight grain, no knots, almost no scent. Milled in Canada. The wider face means fewer boards on a bench, fewer gaps to manage, and a surface that reads as one clean piece from where you sit. We stock hemlock now because we found a clear grade worth standing behind. The light straw color is the point: it makes a modern, neutral room feel intentional, not default. One note: wide hemlock boards can pick up a mild yellow shift under artificial light over time, more noticeable than on narrower stock. Sold by the linear foot.
PROSAUNAS Hemlock 1X4 VG S4SEE Bench, Backrest & Skirting – Sauna Wood
Price range: $5.07 through $50.75Pale, clean, and quieter than you’d expect. This is Hemlock 1×4 VG S4SEE bench board: clear A+ grade, 0.69″ thick, 3.5″ wide, straight-grained, knot-free, milled in Canada. Hemlock has a light straw color and almost no scent, which makes it the right choice for anyone sensitive to cedar aroma or building a room with a modern, neutral look. We didn’t carry hemlock for years because we couldn’t find a supplier with clear grade we trusted. We carry this one now. One real note: hemlock can pick up a slight yellow tint under artificial light over time. If the room is well-lit with daylight it reads beautifully. Sold by the linear foot.
PROSAUNAS Aspen Grace™ 2X3 T&G Wall Cladding – Sauna Wood
Price range: $4.81 through $48.08You 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 Thermo-Aspen Grace™ 2X3 T&G Wall Cladding – Sauna Wood
Price range: $4.60 through $45.98Shadow grooves, thick boards, and a little architecture on your walls. The Grace 2×3 in thermo-aspen is a wide-reveal T&G wall cladding, 1.06″ thick with a 2.2″ coverage per board, designed to make a sauna wall look like a deliberate design choice instead of just paneling. The broad shadow groove between boards catches the light differently than a standard V-joint and gives the room depth. Thermal modification (heat and steam, no chemicals) locks in a warm golden-brown that won’t fade from humidity and won’t gap from moisture cycling. A real statement wall, without the pretension. Sold by the linear foot.
PROSAUNAS Thermo-Spruce 2X4 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $4.56 through $45.60Ben 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 Aspen 1X4 T&G STS4 Wall Cladding – Sauna Wood
Price range: $4.41 through $44.08The Scandinavian default, and ours too. This is natural aspen tongue-and-groove wall cladding, STS4 profile, milled in Estonia at 0.59 in thick and 3.5 in wide with 3.1 in of coverage per board. Pale, bright, no resin, no splintering, and cool to the touch even when the room is running at full temperature. We sell more aspen than any other wood, year after year, because it works: it reads clean in any lighting, it pairs with every heater finish, and nobody is allergic to it. Sold by the linear foot in lengths from 1 to 10 ft.
PROSAUNAS Thermo-Aspen 1X4 T&G STS4 Wall Cladding – Sauna Wood
Price range: $4.38 through $43.78A clean, classic sauna wall in the cladding width most builders start with. The 1×4 STS4 in thermo-aspen is a tongue-and-groove board, 0.59″ thick, milled 3.54″ wide for 3.1″ of coverage per row. The thermal modification takes it to a warm golden-brown that runs all the way through, so trimmed ends match the face and nothing reads as patchwork. Knot-free, no resin, stays cool against bare skin. Easy to run floor to ceiling and easy to pair with a contrasting bench or trim. Sold by the linear foot.
PROSAUNAS Thermo-Aspen 2X3 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $4.22 through $42.25Narrow 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 Aspen 2X3 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $4.14 through $41.40Bare skin at 185 degrees, and this board stays comfortable. The 2×3 aspen bench board, surfaced four sides with eased edges, is the narrow bench option: 1.1 in thick, 2.6 in wide, smooth and resin-free. It’s the right choice for a backrest, a skirting run, or a bench deck where you want slender gaps and a clean, quiet look. We sell more aspen bench wood than any other species, season after season. Sold by the linear foot in 1 and 10 ft lengths at $4.14/lf. Milled in Estonia.
PROSAUNAS Hemlock 1/2X4 VG T&G V2E Wall Cladding – Sauna Wood
Price range: $4.00 through $40.07Pale walls, tight joints, almost no smell. This is Hemlock 1/2×4 VG T&G V2E wall cladding: clear A+ grade, 0.44″ thick, 3.49″ of coverage per board, V-joint profile, milled in Canada. If cedar is the sauna your grandfather built, hemlock is the sauna you’d design today. Quiet, bright, modern. It’s the cladding choice for a contemporary build that wants clean pale walls and a room that doesn’t smell like the wood. Ben likes the hemlock look. The honest note: hemlock walls will shift to a slight yellow tint under artificial light over time, more noticeable in rooms without natural light. For the brightest long-term pale look, our thermo-aspen cladding stays truer. Sold by the linear foot.
PROSAUNAS Alder 2X3 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $4.00 through $40.07Sit on it for five minutes and you’ll understand why Finland has been using alder on benches for a hundred years. This is the 2×3 S4SEE bench board in natural alder, milled in Estonia to 1.1" thick by 2.56" wide, surfaced four sides with eased edges. Warm reddish-brown tone, fine grain, a faint honey scent when the room heats up. Water-repellent and stays cool against bare skin. Good clear cedar now runs nearly three times the price; alder is the honest alternative for a timeless Finnish room. Sold by the linear foot in lengths from 1 to 10 ft.
PROSAUNAS Alder 1X4 T&G STS4 Wall Cladding – Sauna Wood
Price range: $4.00 through $40.03ProSaunas Aluminum Foil Sauna Tape 129725 | 2 in x 164 ft Roll
$38.66The foil goes up fast. It is the seams that leak. This is the tape that closes them: aluminum foil tape made for sauna heat, 2 in wide and 164 ft on the roll. Run it over every overlap between sheets and around each cut you make for the heater feed, light wiring and vents, and your vapor barrier behaves like one continuous surface instead of a wall full of small gaps. We would not put a general-purpose duct tape in a hot room. Pairs with the ProSaunas Sauna Foil Radiant Barrier, 48 in x 80 ft.
PROSAUNAS Alder Grace™ 2X3 T&G Wall Cladding – Sauna Wood
Price range: $4.81 through $38.47The wall profile that makes people stop and ask what species that is. Grace is a wide tongue-and-groove with a precision shadow reveal, and in natural alder the warm reddish-brown tone makes those grooves pop. Each board is 2.52" wide with 2.2" net coverage, milled in Estonia to 1.06" thick. Dramatic for a wall, clean for a ceiling, honestly different from the usual sauna paneling. Pairs with any alder bench board for a matched room. Sold by the linear foot in 1 and 8 ft lengths.
Thermo-Aspen Moulding 1×2 Transition T by Thermory
Price range: $2.36 through $37.76Need longer boards than available by Thermory? We make those transitions easy with this T moulding to avoid gaps with a professional look. Common on walls and ceilings in commercial saunas.
Note: These will arrive directly from Thermory USA in bundles of two in 7′ and 8′ lengths.
PROSAUNAS Western Red Cedar 2X4 STK S4SEE Bench, Backrest & Skirting – Sauna Wood
Price range: $4.67 through $37.40Knots and all. Western Red Cedar 2×4 STK S4SEE is the thicker bench board for the builder who wants the weight and depth of a 1.5″ seat without paying clear-grade prices. STK means Select Tight Knot: the knots are natural, tight, and part of the character. At 3.5″ wide and 1.5″ thick, this is a substantial bench board with a real cedar look. The aroma is there, the reddish grain is there, and the lower price point makes a full bench build more realistic. Honest downside: the knots and the STK-grade movement mean these boards gap a bit more than clear VG over the years. Milled in Canada. Sold by the linear foot.
PROSAUNAS Aspen 2X2 S4SEE SHP Moulding & Trim – Sauna Wood
Price range: $3.60 through $36.071.1 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.
Alder Wall To Wall Flat T Transition Trim
$34.80Need longer wall cladding boards in alder than those available by Thermory? We make those transitions easy with this T moulding to avoid gaps with a professional look. Common on walls and ceilings in commercial saunas.
Note: These will arrive directly from Thermory USA in bundles of two in 7′ and 8′ lengths.
PROSAUNAS Alder 2X2 S4SEE SHP Moulding & Trim – Sauna Wood
Price range: $3.48 through $34.73The trim piece that pulls a room together. This is the alder 2×2 S4SEE moulding: 1.1" square (1.1 in x 1.1 in), surfaced four sides with eased edges, milled in Estonia from natural alder. Use it to cap bench edges, frame out a heater enclosure, or add a furniture-quality line wherever you need one. Warm reddish-brown tone matches the alder bench and cladding family exactly. At $3.48 per linear foot it’s the least glamorous piece in the room, but the room looks noticeably better with it. Sold by the linear foot in 1, 8, 9, and 10 ft lengths.
PROSAUNAS Thermo-Aspen 2X2 S4SEE SHP Moulding & Trim – Sauna Wood
Price range: $3.34 through $33.40Moulding that actually does something. The thermo-aspen 2×2 S4SEE SHP moulding at 1.1″ x 1.63″ is the piece you reach for when you need to cap a bench edge, cover a gap at the ceiling, frame a light channel, or add a clean horizontal break on a cladded wall. It’s the same thermal modification as the rest of our thermo-aspen line: heat and steam, no chemicals, golden-brown color all the way through, no warp, no resin, cool under bare skin. Available up to 10-foot lengths. Sold by the linear foot.
PROSAUNAS Thermo-Spruce 1X4 T&G STS4 Wall Cladding – Sauna Wood
Price range: $2.35 through $32.96The 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.
