Everything inside the sauna, in the order we build: foil with taped seams, then two vents, then wall and ceiling boards, benches, door and trim. Buy in that order too; the foil, vents and light wiring go behind boards you are about to close.
Most of the wood here is thermally modified with heat and steam, so it stays flat through years of heat cycles. Add 10 percent to your board count for cuts and waste. Start with sauna wood, then benches, doors and vents. Or draw the room in SaunaDesignPro and it counts the boards, foil, vents and trim.

SaunaLife SaunaTrekker Bench | Folding Cedar

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 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.
