What do you call this room in the picture?

I'm of Finnish descent, so I grew up loving saunas

I would like to be in a sauna!! but I'm gonna have to wear my revealing clothes!! which I wear like everyday!!

Since my face doesn't perspire, I'd be afraid of getting overheated. Otherwise, it would probably be relaxing.

great for clearing the airways

It is also a steaming room. Many use is, when they go to a salon
