We've been in the steam room/sauna business for over 26 years and it's always nice to see someone giving informed information.

The only thing I can think to add, since you specified that the sauna is a wooden room, is that the steam room is made out of something non porous (tile, acrylic, etc). Some people even use materials such as marble/natural stone, but it's important to note for anyone planning on building a steam room that using marble or natural stone means you must use a larger, more powerful steam generator, since it's so much harder to heat up.

Again, great answer.
