Found out my old house has a hidden shutoff valve for the whole bathroom

I was trying to fix a dripping sink faucet in my 1950s place and couldn't find the shutoff under the sink. After a bunch of looking, I pulled out a plumbing book from the library and it mentioned a 'main fixture valve' sometimes being in the wall behind an access panel. Sure enough, there was a little metal plate behind the toilet I'd never noticed. Popped it open and there was the valve. Has anyone else run into one of these in an older home? I'm curious how common they are.

Oh man, that beats my method of just yelling at the pipes until my neighbor comes over. My old apartment had one of those behind a weird little door in the hallway, and I only found it after the plumber showed me. Seems like they just loved hiding the important stuff back then.

Yeah but @dakotacraig, that little door is usually the main shutoff for the whole unit. They kinda have to put it where they can get to it without coming inside, you know?
