To the saunas

You go into the hallway with the saunas. It is a long corridor with three glass doors. Behind each one is a sauna room. It's unclear what awaits you behind each door.

Here, the only thing you can do is to try it out and hope for the best.

You hang up your bathrobe and exchange it for a towel, which you wrap around your waist. Now you just have to decide on a door.

Which door do you take?
