When a swimhall has two saunas, a "hot" and a "hotter", I'd guess they are at about 70°C and 90°C.

70-90 seems reasonable, 90 is already over my comfort which is around 80, but the post talked about >90 degrees which just seems stupidly hot

I don't know anyone who wants sauna that hot - steam is involved. Numbers over 90 sound like dry heat only. My 0,02€.
