Prison maybe, but don’t forget about jails. I’ve visited jails in panopticon “pod” setups for 40–50-ish people bunked two-each in rooms with no bars (just a painted line dividing cells from common areas) that had a single separate common restroom/shower where each trip must be requested and approved. San Francisco’s jail is like that.
