ProSaunas
ProSaunas is a Minnesota sauna-component supplier, and the doors are the part they build themselves. Solid Douglas Fir is hung in a Hemlock jamb at their Sauna Craft Center in Minnesota, with insulated dual-pane tempered glass and self-closing hinges. The rest of the line is the inside of the room, made in Estonia, Canada and Finland, so the wall cladding, the bench boards and the corner trim can all be matched in one species.
We carry 65 ProSaunas items, and the one that leaves here most often is the foil: the 48 inch by 80 foot radiant barrier, usually on the same order as the thermo-aspen vents and a run of sauna wood. We size these rooms ourselves, so send a drawing and we will come back with the roll count, the vent holes and the hinge side. The number is (844) 565-1113.
ProSaunas questions
What rough opening does a ProSaunas door need?
The prehung Douglas Fir door in the 24 by 80 size sits in a 25.5 by 81.5 inch frame and wants a 26 by 82 inch rough opening. The 24 by 73 all-glass door frames into 27.5 by 75.5 inches. Both arrive prehung, so you are setting a finished unit rather than building a jamb.
How much wall does one roll of ProSaunas sauna foil cover?
One roll is 48 inches by 80 feet, which is 320 square feet, and that is enough for an 8 by 7 by 8 foot room. It is pure aluminum, a Class I vapor retarder, and it reflects up to 97 percent of radiant heat. Tape every seam, then furr out a 1×2 air gap before the cladding goes on.
Which ProSaunas light kit goes under a bench?
The universal kit ships as one 16 foot strip or two 10 foot strips, 3,500K warm white at 99 lumens per foot, sealed to IP67, powered by any HUUM, Harvia or Saunum heater with external controls or by a standard 110V outlet on a switch. The dimmable kit is rated to 200°F, runs on 24VDC, and dims to 1 percent.
What size hole do the ProSaunas vents need?
Cut 4 inches. Both the fixed grille and the adjustable hatch fit over a 4 inch hole, and the hatch mounts flush with pin nails over a 4 by 4 inch pass through. The hatch face is 11 by 5.2 inches, the grille 5.9 by 7.5. Put the intake low beside the heater and the exhaust high in the far corner.
ProSaunas Cubist Black Decorative Sauna Wall Panels | 6-Panel Box
$343.20Squares, set in relief. Cubist Black covers the wall in 3.1 inch blocks of abachi stained a deep, brushed black, and the stagger between them gives the surface a depth that flat cladding cannot fake. It is the most architectural pattern in the SaunaDécor series, at home in a modern sauna or on a spa accent wall. Six CNC-cut panels to the box, 10.7 square feet of coverage, joined like puzzle pieces with no fasteners showing.
ProSaunas Modern Black Decorative Sauna Wall Panels | 6-Panel Box
$319.20A black sauna wall sounds like a dare until you see what it does for the light. Modern Black takes the irregular hexagon pattern, stains the heat-treated abachi a brushed black, and leaves the cut edges of each piece warm and raw, so every shape carries its own thin outline of natural wood. Against pale aspen cladding the effect is striking without shouting. Six CNC-cut panels per box, 9.3 square feet, no exposed fasteners.
ProSaunas Modern Thermo Decorative Sauna Wall Panels | 6-Panel Box
$303.20Does a patterned wall have to repeat perfectly? This one argues no. Modern Thermo scatters irregular six-sided pieces, each 4.6 by 6.1 inches, across the wall so the geometry feels drawn rather than stamped. The wood is heat-treated abachi, sanded smooth, with the warm color and faint sweet aroma the treatment leaves behind. Six CNC-cut panels per box covering 9.3 square feet, joined like puzzle pieces with nothing screwed through the face.
ProSaunas Hive Thermo Decorative Sauna Wall Panels | 6-Panel Box
$391.20The bigger hexagon, in warmer wood. Hive Thermo runs its honeycombs at 6.7 by 7.6 inches, roughly double the scale of our Hive Aspen pattern, cut from abachi that has been heat-treated for stability in sauna conditions and sanded smooth. The treatment leaves the wood a warm caramel tone with a faint natural aroma that hangs around for years. Six CNC-cut panels to a box, 12.7 square feet of coverage, and no visible fasteners anywhere on the finished wall.
ProSaunas Hive Aspen Decorative Sauna Wall Panels | 6-Panel Box
$399.20Honeycomb, in solid aspen. Hive Aspen is the light-wood hexagon panel in the SaunaDécor series from ProSaunas: six CNC-cut panels to a box, 13.4 square feet of interlocking coverage, no exposed fasteners on the finished face. The aspen is left natural, so the wall reads pale and calm next to darker cladding, and each hexagon lands at exactly 3.3 by 3.7 inches because a machine cut it, not a jig saw. Made in Kiili, Estonia, by the same people who mill the aspen cladding we sell every week.
ProSaunas 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.

Upgrade your sauna (or any moisture-prone space) with the barrier trusted by serious sauna craftsmen.

ProSaunas Oiled Birch Sauna Ladle | 14.5 in, Made in Estonia
$27.20A ladle is the one tool in a sauna that everybody touches. This one is oiled birch, 14.5 inches from end to end, with a long handle that keeps your knuckles out of the rising steam and a wide, shallow bowl that lays water across the stones instead of punching a hole in the middle of them. Made in Estonia by the same people who mill our thermally modified cladding. Oiling is what separates the two versions we carry. The oil closes the grain a little further, so the ladle sheds water faster and keeps its colour longer against the constant wet and dry cycle of a sauna. It is the sort of thing you buy once and stop thinking about.
ProSaunas Birch Sauna Ladle | 14.5 in, Made in Estonia
$25.50A ladle is the one tool in a sauna that everybody touches. This one is birch, 14.5 inches from end to end, with a long handle that keeps your knuckles out of the rising steam and a wide, shallow bowl that lays water across the stones instead of punching a hole in the middle of them. Made in Estonia by the same people who mill our thermally modified cladding. This is the plain birch version, left natural. It will grey slightly with years of use, the way untreated birch does, which some people prefer and some do not. It is the sort of thing you buy once and stop thinking about.

Available in Alder, Spruce or Thermo-Aspen
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. The thermal modification gives it a warm golden-brown tone all the way through, so cut ends match the face. Knot-free, no resin, stays cool to the touch. A clean choice when you want a broad, quiet wall. Sold by the linear foot.
PROSAUNAS Alder 1X5 T&G STS4 Wall Cladding – Sauna Wood
Price range: $6.54 through $65.45
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-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-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.
PROSAUNAS Thermo-Aspen 1X2 UK Door Trim – Sauna Wood
Price range: $3.15 through $25.23The 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
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 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 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 Thermo-Aspen 1X2 SI Inside Corner Trim – Sauna Wood
Price range: $1.58 through $12.65Inside 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.
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-Aspen 2X2 VA Outside Corner Trim – Sauna Wood
Price range: $3.15 through $25.23An 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.
PROSAUNAS Aspen Midnight Black 1×4 (0.59 in x 3.5 in) T&G STS4
$7.34PROSAUNAS Aspen Midnight Black tongue and groove 1×4 STS4 profile creates a striking contrast and is recommended for sauna walls and ceilings. This black-wax finished cladding is perfect for creating a dynamic, contemporary look. When paired as an accent wall with different bench and surface woods, its smooth black appearance will complement the lighter materials.
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 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 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 Spruce 1X4 T&G STS4 Wall Cladding – Sauna Wood
Price range: $1.33 through $18.68The most economical real sauna wood we carry, and the traditional one. Natural Nordic 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 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 Western Red Cedar 1X4 STK T&G V2E Wall Cladding – Sauna Wood
Price range: $2.64 through $21.16The knottier option, and honestly the one with more character. This is Western Red Cedar 1×4 tongue-and-groove V2E wall cladding in STK grade, milled in Canada with natural tight knots and a warm reddish tone. At 0.70″ thick with a 2.95″ coverage width, it goes up fast and smells like every sauna movie you’ve seen. STK means you’ll have knots: they’re tight, they’re natural, and they give the room a cabin-honest feel that clear boards don’t. We carry a clear VG grade too if that’s your look. One heads-up: like all untreated cedar, this will move a little through the heat-and-cool cycle over the years. 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 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 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 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.
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 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 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.
