Here’s part of an email with Josh, who is happily building his own sauna:

Josh..

Good question on the sauna door.  I make my own. Here’s what you can do:

1. Frame and your interior wall, frame for about a 26″x6′5″ sauna door.
2. Cut a piece of plywood sheathing 3/4″ less than your height and width.  This is the basis for your sauna door.
3. tongue and groove panel the outside face of your plywood.
4. Staple foil bubble wrap insulation to the inside face of your plywood.
5. Tongue and groove cedar the inside of your door, on top of the foil wrap.  Tip: run your siding the opposite direction as your walls, it looks better.  If you really want to be resourceful, you may be able to use your cedar t&g cuts from your walls to make a really cool pattern.
6. nail in a door stop to your door frame.
7. Screw in some hinges and a funky wood door handle.
8. Hang your door.
9. Leave a slat towards the bottom for air flow. This is the best way to vent your sauna.
10. Door window:  It’s easy to use a skill saw to cut out for a window.

The end result is that you have a nice solid 2″ door.  (5/8″ plywood, 2@ 5/8″ paneling).

Josh, you going with a Kuuma Stove from Tower?
