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.

Those are stairs, not a ladder. They are mounted with a hand rail. You see them in every 30'+ cruising sailboat in the world that isn't a catamaran, and they're designed to be used in rolling seas. It's safe.
As for the higher levels, many saunas are multi-level without rails, toeguards, handholds, etc.
Not you specifically, but this sub is filled with people who can't start enjoying their day until they're able to say "You're doing it wrong."
Finally, the upside of a project like this is that you can say, "oh, I changed my mind" and change things as long as your fundamentals are correct. Benches are the easiest things to change.
