We offer the largest variety of sauna quality lumber available on the internet! Proper sauna tongue and groove paneling woods are typically kiln dried to 8% moisture, which stabilizes wood fibers for sauna use. This greatly reduces warpage and shrinkage of boards once installed. The most popular sauna wood paneling types are tongue & groove white aspen and western red cedar. Complete your sauna wood paneling installation with a trim package of cove molding, baseboard and door trim in Cedar or Basswood.
Aspen sauna wood paneling is a great choice for any residential or commercial sauna. Public saunas, health club saunas and hotels can accommodate more sauna guests with this doctor recommended, non-allergenic type of Aspen sauna paneling. Certain health conditions can be irritated by the scent of cedar sauna paneling, so aspen paneling is an excellent alternative choice. Many doctors actually recommend aspen saunas for people on detoxification programs.
Sauna wood trim will complete your sauna project, just finish cut for an exact fit. Cedar or Basswood types of trim will match most light or dark sauna paneling. Or select wood type to contrast with your sauna wood paneling, such as bright basswood trim against red cedar sauna paneling or darker cedar trim against white aspen paneling. Trim for walls and ceiling is the cove molding type. Trim for sauna doors transitions from low profile inside edge to full thickness at outer edge. Cut door trim at 45 degree angles on corners for a seamless look.

Paneling Tips
Aspen tongue and groove sauna boards are most commonly installed vertically for a seamless look and less waste, as the most common board length is 8' length. Some people prefer the horizontal look of sauna woods, which usually costs more because there is more waste. For example a 5' wide x 7' high wall paneled vertically would only have about 1' of waste on each board. This wall paneled horizontally would have almost 3' of waste. Most of our paneling woods are available in several lengths for minimal waste on-site installing the sauna kit.
Other Manufacturers may sell this paneling size as a 1" x 5" (which is starting rough size before finish milling) and priced per linear foot. We offer actual sized paneling, priced per square foot that is much easier to calculate for sauna building.
Tongue and groove wood paneling can be installed horizontally or vertically. Vertical is most common because there is usually little waste for a 7 foot ceiling height. We have several common lengths of sauna paneling in stock: 6', 7', 8', 9', and 10' lengths. (Nordic Spruce currently only available in 7' lengths.) The usual size of tongue and groove sauna paneling is 3/4" thick x 4" wide in 7 or 8 foot lengths. Some wood types may be available in 1" x 6" sizes. In most vertical applications you will need to fasten 2" x 2" nailers to the studs for proper backing to secure paneling to. Be sure to add supports behind the paneling where benches and a sauna heater will be installed.
Another option for an attractive pattern if you prefer end matching. Simply cut ends at a 45-degree angle. This is a great and economical way to minimize waste.
