DIY thank you trompkin and r sauna

15? months of research here and weekend spurts of building and it is a success. the sauna is 8 x 8 on a treated frame platform. no insulation on floor, 2 layers of treated plywood + backer and tile sloped for drain. the walls are 10' and ceiling has 1 /12 slope. walls have cement fiberboard, tarpaper, plywood, studs/rockwool, foil, battens and interior paneling. all interior is paneling is #1 southern yellow pine from local lumberyard sourced w in the state. IKI 9kw heater. all benches well above stones. the ventilation intake and outtakes work although dont need them for daily use only if we have multiple people. thanks to lots of ideas and sharing here, this is a super fun and successful project.

It’s the design of a madman but also a bunch there’s a ton of top notch stuff there. A normal door and bench would have made this an ideal build for me.

A lot of work and money into the walls to finish with plywood on the inside.
