Recessed floor section in my hotel's utility area
There's this weird tub-like recessed section in my hotel's utility area. My first guess was a place to wash stuff, but there doesn't seem to be a faucet nearby nor a drain for the water.
There are staff-only rooms on the other side, so one must cross this area to go there. I'd imagine it's not really practical if, when used, this alley was to be blocked. And also, it's not hidden at all from the guests. Just to the right of this is the stairs leading to the rooms.
