Here’s a 3-D picture of a pretty good mobile sauna.
- 8×12 structure
- 6×8 sauna room*
- 6×8 changing room
- dual benches on either side.
- stove centered along the back wall.
- 2×4 framed construction
- 5/12 roof pitch
- put a window in your sauna if you have a nice view.
I have been in over 100 saunas, and have sat in every one and have considered what’s good, bad and ugly with the design and construction of each sauna.
Some saunas are two man saunas, and don’t allow for a good sauna party. Some saunas are bigger than a four man sauna and take too long to heat up, use too much wood, or the loyly (steam rising from tossing water on the rocks) never reaches you. With divine proportion, according to the Greeks and confirmed by Da Vinci (thanks Matt), this is my ultimate sauna plan.
This design uses North American standard measurements, minimizing waste in construction and allowing for full cuts of material. This design gives you a changing room, a critical space for privacy, having a beer between rounds, and a buffer for temperature extremes in cold climates.
TIP: Frame the interior wall with 2×2’s vs. 2×4’s. (just sheath the wall with 1/2″ plywood for rigidity). This is a non load bearing wall, and the extra 1.5″ sure is valuable!
EXTRA TIP: * The interior wall can be nudged slightly to allow for a slightly bigger sauna room (say 6’2″x7’4″ interior dimensions). Four people can fit nicely along a 6’2″ bench, and it’s nice to lay along your sauna bench. A comfy sauna and ample changing room is the goal. Having a bunch of people over for a sauna party? don’t sweat it! click here for the sauna party equation.
3/5/15 update to post:
The 3D drawing above may not be the best stove placement. Thanks to Adam comment below, here is arguably two different configurations each offering advantages of:
- more standing space.
- less staring at each other on the bench vibe.
- less bumping into the stove ouch.
- asymmetrical flow, best discussed between rounds in the garden all misty wet with rain.
