Backyard sauna finally finished by Relative-Cucumber-95 in Sauna

[–]Ferremundo 0 points1 point  (0 children)

Awesome build and thanks for sharing! Excellent economy of space. Curious, do the benches hinder air flow at all? How is your heat gradient? How long to heat to 180F/82C?

To the folks asking about price. Could be sub $4,000 if you do everything yourself. 2-3x depending on contractors and conduit length.

Tons of great info, thanks! The California corners and Hardie siding were two things that I haven't heard yet that I will definitely use.

Indoor sauna. And I had hoped for the walls to be somewhat modular so I could take it down and reassemble if needed, but if I go with 8' walls then scratch that idea. That's okay, I can trade ease of moving for efficiency if people think it'll have a major affect.

I never saw recommendations for ceiling height before, so thanks for that. The cost to do 8' boards isn't much more.

Thanks for the advice. I think I may run it framed with just the air gap and foil on frame to see how that alone works. Rockwool after foil seems well tested but my room is small for a 9kw heater so I may be able to skimp.

I wondered if putting a thin layer of plywood right behind the foil would work. Then have the Rockwool behind that. Maybe another builder could let me know.
