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.

Price range: $33.15 through $41.65

Half a turn on the wall and the next round starts. This ProSaunas sand timer screws to the sauna wall on its own mounting plate and rotates in place, so you restart it without taking it down or setting it on the bench.

ProSaunas S-Shaped Sauna Backrest | Pine or Cedar, 15.5 x 20.5 in

Price range: $58.65 through $75.65

Sauna walls are built to hold heat, not to lean on. Set this ProSaunas backrest on the bench, tip it against the wall and sit back into an S-shaped frame designed to fit and support your back: two curved rails with round dowels between them, 15.5 in wide and 20.5 in tall. Slip-resistant pads on both ends keep it where you put it. It is handmade and polished from knotless pine or knotless Canadian red cedar, and there is nothing to install, so it moves to whichever seat needs it.

ProSaunas XL Wood Sauna Bucket | 3.17 gal, Spruce or Thermo-Aspen

Price range: $129.20 through $149.60

A long round with friends goes better when nobody has to leave the bench for more water. The ProSaunas XL is a staved wood bucket that holds 3.17 gallons, stands 8.5 in tall at the rim with two handle tabs rising to 12 in, and comes in natural spruce or thermo-aspen. It is designed and engineered in Estonia. There is no plastic liner in this one: the wood holds the water, the traditional way. A ladle is not included, so plan on pairing it with one.

ProSaunas Wood Sauna Ladle | 3.4 or 5.1 fl oz, Pine or Cedar

Price range: $24.65 through $41.65

Your heater’s manual has an opinion about ladles. Harvia and Saunum both cap a single throw at 6.4 fl oz, because water the stones cannot turn to steam comes back off them as boiling splash. Both of these ProSaunas ladles hold less than that: the small one 3.4 fl oz on a 14.2 in handle, the large one 5.1 fl oz on a 16 in handle. Each comes in knotless Finnish pine or knotless Canadian red cedar, with a hemp rope loop at the end of the handle.

ProSaunas Stainless Sauna Pail and Ladle | 1 gal, Bentwood Handle

$84.15

A sauna pail does not have to be wood to belong in a wood room. This ProSaunas set is polished stainless steel: a 1 gal pail with a bentwood handle that arcs over the top, and a matching steel ladle with a large bowl. The shine sets off the timber around it, and the water touches only steel. The pail is 10 in across and 7 in tall; the ladle is 16.5 in long. Designed and crafted in Finland.

ProSaunas Stainless Sauna Bucket and Ladle | 1 gal, Upright Handle

$67.15

Steel where the water goes, wood where your hands go. This ProSaunas set is a 1 gal stainless steel bucket with an upright wooden grab handle and a matching stainless ladle with a wooden grip, so the two parts you hold are both wood. The bucket is 12 in across and 13 in tall to the top of the handle; the ladle is 17 in long. Designed and crafted in Finland.

ProSaunas Spruce Sauna Pail and Ladle | 1 gal, Bail Handle

$84.15

Step out of the heat, lift the pail by its bail, and tip cool water over your shoulders. ProSaunas built this spruce pail for exactly that douse: 1 gal of water, a bail handle that swings up over the top, and a plastic lining to prevent leaks. A matching carved spruce ladle, 16.5 in long, comes with it for the stones. The pail is 11 in across and 7.5 in tall. Designed and crafted in Finland.

ProSaunas Spruce Sauna Bucket | 1 gal, Upright Handle, Lined

$50.15

The handle comes up to meet you. This ProSaunas spruce bucket has a single upright handle that brings it to 17.5 in tall, so you can lift it off the floor with one hand without folding over on a hot bench. A plastic basin inside keeps the water off the wood. It holds 1 gal, weighs 1.7 lb empty, and is hand-stained to bring out the grain of the natural spruce. Designed and crafted in Finland.

ProSaunas Sauna Wax | Water-Based, Clear or Tinted, 15.2 fl oz

Price range: $22.87 through $23.72

Clear, white, gray or black: the color you pick decides whether this wax protects your sauna’s wood quietly or changes how it looks. ProSaunas Sauna Wax is a natural water-based sealant for saunas and other interior wood. It builds a protective coating that reduces heat and moisture absorption, and a 15.2 fl oz can covers about 44 to 63 sq ft per coat. Extra coats deepen the tinted colors. It goes on with a brush or sponge and dries in 1 to 2 hours.

ProSaunas Sauna Thermometer and Hygrometer | Pine or Cedar

Price range: $41.65 through $58.65

Is the sauna running cool, or is the gauge simply hanging lower than the heater’s sensor? This ProSaunas board puts two analog dials side by side: a thermometer that reads 40 to 240°F and a hygrometer that reads humidity from 0 to 100 percent, behind glass made to resist cracking and leaks. The board is 9.8 in wide and 4.9 in tall, in knotless Finnish pine or knotless Canadian red cedar, with screws and calibration tools in the box.

ProSaunas Sauna Paraffin Oil | Odorless Wood Oil, 16.9 fl oz

$24.57

Pick a day you will not use the sauna, because this oil wants 24 hours to dry. ProSaunas Sauna Paraffin Oil is an odorless treatment for the wood your skin touches most, the bench tops, backrests and headrests, which is where ProSaunas says it works best. It reduces how much heat and moisture the wood absorbs and brings up its natural tone. One 16.9 fl oz bottle covers about 54 to 97 sq ft, applied with a cloth or a brush.

ProSaunas Sauna Cleaner | 32 fl oz Spray or 1 gal Concentrate

Price range: $16.37 through $29.12

Every session leaves sweat on the benches, and over time it shows in the grain. ProSaunas Sauna Cleaner is formulated for wood saunas: it breaks down embedded dirt, grease and grime, deodorizes with a clean, fresh scent, and restores the wood’s luster. Buy the 32 fl oz spray, premixed and ready to use, or the 1 gal concentrate, which makes up to 4 gallons of cleaner once mixed with water.

ProSaunas Sauna Bucket and Ladle Set | Rope Handle, 1.1 or 1.6 gal

Price range: $83.30 through $100.30

Fill either bucket and it holds 40 of its own ladles. Each bucket has a clear plastic liner to keep water off the wood, and the bucket and ladle both carry hemp rope. Choose knotless Finnish pine or knotless Canadian red cedar.

ProSaunas Oval Wood Sauna Bucket | 2 gal, Spruce or Thermo-Aspen

Price range: $101.15 through $118.15

Round is not the only shape a sauna bucket comes in. This ProSaunas bucket is oval, 16 in long and 10.5 in wide, so its 2 gallons sit low, just 6.5 in at the rim, and it lies along the bench instead of claiming a square of it. Two handle tabs rise to 9 in. Choose natural spruce, thermo-aspen, or oil-rubbed thermo-aspen, which ProSaunas rubs with sauna oil for a deeper color and a refined luster. Designed and engineered in Estonia; ladle sold separately.

ProSaunas Hand-Stained Spruce Bucket and Ladle | 1 gal, Rope Handle

$84.15

Brown, not blond. For a sauna with darker wood, ProSaunas hand-stains this spruce bucket and its matching ladle to bring the grain forward, so the pair looks warm and deep instead of the pale yellow of raw spruce. A plastic basin inside keeps the water off the wood. The bucket holds 1 gal and carries on a thick natural fiber rope; the ladle is 15 in long. Designed and crafted in Finland, and sold together as a set.

ProSaunas Aromatherapy Stone Cup | Granite, Stainless Insert

$24.65

A sauna scent does not have to go in the bucket water. This ProSaunas cup is made from natural granite, 2 in across and 1.2 in tall, with a stainless steel insert that holds the oil. ProSaunas says you can set it anywhere in the sauna, including among the heater stones, and let the scent rise from there. It weighs 0.4 lb and makes an easy gift for someone who already owns a bucket and ladle.

ProSaunas Spruce Sauna Ladle | 17 in, Deep Bowl

$24.65

Seventeen inches, end to end. That reach is the reason to pick this ProSaunas spruce ladle when your heater sits behind a safety rail or a step beyond the bench: you pour from where you sit. The bowl is deep and round, the handle is long and smooth, and the whole ladle weighs 0.35 lb. ProSaunas hand-stains the spruce to bring out its grain. Designed and crafted in Finland.

ProSaunas Cubist Black Decorative Sauna Wall Panels | 6-Panel Box

$343.20

Squares, 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

$319.20

A 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

$303.20

Does 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

$391.20

The 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

$399.20

Honeycomb, 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 Round Thermo-Abachi Sauna Ventilation Cover

Price range: $111.20 through $119.20

The 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.

Vent cover only. Ductwork, fans and a complete ventilation system are not included.

ProSaunas Oiled Birch Sauna Ladle | 14.5 in, Made in Estonia

$27.20

A 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

$25.50

A 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.

PROSAUNAS Aspen Midnight Black 1×4 (0.59 in x 3.5 in) T&G STS4

$7.34 per linear footFree samples available

PROSAUNAS 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.

This product has multiple variants. The options may be chosen on the product page

ProSaunas Aluminum Foil Sauna Tape 129725 | 2 in x 164 ft Roll

$32.86

The 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 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-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 2X4 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood

$6.15 per linear footFree samples available

A 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 1X5 T&G STS4 Wall Cladding – Sauna Wood

$6.76 per linear footFree samples available

A 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.

$4.38 per linear footFree samples available

A 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.
