Sauna Kit Construction Details
From Sauna Craft
Use 2" x 4" construction grade spruce studs to frame the walls and ceiling. If the ceiling span is over 10', use 2" x 6" studs. Unless otherwise specified, for saunas up to 8' x 8', the walls are LINED HORIZONTALLY and FRAMED VERTICALLY. Frame the walls at 16" on center. Frame or strap the ceiling to an inside height of 82-1/2". Frame the ceiling so that the cedar will run the shortest direction. Provide extra blocking for bench supports and heater.
Electrical rough-in of heater, control and light should be done at this time. If using a remote thermostat (TPT-3 or EPC-9), the thermostat should be installed on the wall outside the sauna.(See heater specifications and control wiring diagrams for wire and breaker sizes.) Hook-up of the heater and light can be done after the sauna is completed.
The space between the studs in the walls and ceiling is filled with 3-1/2", R-12 fiberglass insulation.
Foil vapour barrier over the inside edge face of studs over the insulation.
If lining vertically, strap (1" x 2" or 1" x 3") over the foil to change direction. Can be used to create air space, but it is not necessary.
Use the specified lengths of tongue and groove cedar (see "Material Packing List"). Depending on the actual inside finished size of your sauna, it may be necessary to trim these boards. Nail through the tongue only in order to conceal all nail heads (Blind nailing). Use the 1-1/2" nails supplied. Install the tongue and groove cedar to the ceiling first. Start lining the walls at the floor and work your way up. The first cedar board should be left about 3/4" off the floor. Cut the last board to fit.
Fasteners supplied are galvanized nails and Deck King treated screws. All fastening is to be blind nailed.
There are clear cedar 2" x 4" boards for the bench construction. Depending on the actual inside finished size of your sauna, it may be necessary to trim these boards. Before doing any fastening, select the boards to make sure the better face of the board comes out on the sitting surface. When building the benches, the better side will be face down as you are fastening from the bottom. This is so there are no screws on the finished surface. Use the 2-1/2" treated screws supplied. If the sauna is 5' or more deep, the top bench is 20" deep and the bottom bench is 16" deep. If the sauna is 4' deep, the benches will be 20" & 8". Spacing between the bench boards should be 1/2" - 5/8".
Cedar framed full-length glass door or Solid cedar door with small window. Pre-hung on ½" x 4-9/16" mahogany jamb. DOOR OPENS OUT. Standard size 24" x 74". Rough opening is 26" x 76-1/2".
Sauna Craft heaters can be mounted in the corner or on a straight wall. Tylo Sauna Heaters are designed to mount on the straight wall.
Install the heater guard with a 4" clearance around the heater extending about 6" above the heater (12 kw & larger, 6" clearance). Use the 2" x 2" for the vertical posts and the 1" x 3" (or 4") for the horizontal rails.
(Included in kits to USA, extra for others) Use 1" x 4" cedar, square edge laid over cedar sleepers. Build as with benches with good face on walking surface. Top boards should be spaced 1/2" apart. The sleepers should be placed at 1'-0" on center.
Commercial saunas should have a drain in the center of the floor (sloped to the drain) to facilitate cleaning. Most residential saunas have drains, but it is not essential. Water should only be used in moderation. It is splashed on the rocks and evaporates.
For residential, tile is attractive and functional; however it is also acceptable to leave concrete. Tile the floor and up the wall 2-3".
