Not the person you asked, but I’m guessing it’s because it feels oddly empty and strange (notice how the back wall is a mirror that feels like a wrong and overly dark window, and the seats are odd). Essentially its a liminal space, which many people find unsettling.
Edited to add: plus the steam in the room causes the light to seem strange and overly diffuse
I thought it might be a window, but it was so dark I wasn’t sure. Still very liminal.
& i think maybe it might be creepier to someone who has been in those spaces before? Often people who find liminal spaces creepy it’s because they’re used to them in a different context than the photo. So usually the bathhouse would have people and it would probably be light outside, which isn’t the case here.
I dunno definely interesting lol
