As an Estonian, anything below 80°C is considered a "kids sauna". 80°C - 90°C is a cold-but-workable sauna and proper sauna starts from 90+°C. I'd assume it's the same in Finland as we share a lot of the sauna culture.

This would be same in Germany and eastern european countries too. But it really depend on humidity. High humidity saunas don't have to be hot and get tough pretty quicky. 100c dry sauna is lot more manageable than 60c humid sauna (atleast to me).

		Indeed, humidity matters a lot. Most our saunas here are löyly (in Finnish) saunas, so you get a rollercoaster of dry - humid - dry cycles. Once you get to 100+c and throw a good amount of water on the stones, it can get quite challenging to endure :) Everybody has their personal preference of course. For me, the sweet spot seems to be a moderately humid sauna at 93c. At that point, the löyly is not too harsh yet but is still hot enough to make you feel alive :)

		My steam room (at home) at 116F/47C is close to the upper limit of bearable for me. But that's a lot more humidity than even a humid sauna.

90+ sauna sounds painful. Are you actually throwing water? Because even with 80 the steam is pretty hot

		Whether sauna is hot or not depends on whether you enjoy the cold water plunge afterwards :) The typical preset on dry saunas in Bay Area is ~165 F (73 C). Which is cold. Loss of time and money :). Usually, by closing or throwing cold water on sensor, one can make it to 180-190 F (82-87 C) - this is where you start to feel like you are in sauna, though it takes prolong time to heat you up enough to enjoy the cold plunge. If you're lucky enough, you can get to 200, 210, 220 F (104 C) - this is where you start to feel relaxed with heat working inside you. Of course those numbers would be impossible to enjoy in steam sauna.
