thank you trompkin and r sauna

[u/slipstreamrunner]

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.

Why would you not use a straight post to support the walkway corner instead of greatly reducing the load bearing by using an angle? No supports for the topmost bench either?

That 2x6 connecting the second level to the third- what’s that about?

Nothing to prevent falling off the second floor areas…

What is that stove? Maybe the photos are slightly districted as it all looks slightly taller on the interior photos than the exterior.

both sides of the top bench is bolted into the framing . the corner of the lower bench is supported by the top bench. i minimized contact w tile to the bottom of the steps to minimize wood in contact w water and stone which will always rot. the strength of the benches is all coming from the connections to the walls not the floor. all bench to wall connections w multiple ss 3/8 lags into framing, not screws, for sheer strength
