I Need To Study

How many bathrooms make sense to you for an omegaverse world? How would you split them up? And give your reasoning.

I'm a stingy bitch who's paranoid about safety so I would have a community sink/dryer/mirror area and then unisex individual bathrooms with toilets, sinks & dispensers for medicine, tampons, etc. The only problem would be that wait times would be longer unless the building has a bunch of them, which would cost a lot more than just toilet stalls ┑ (￣Д ￣)┍

These are thoughts that pop up in my head when I'm supposed to be sleeping lol. I'm curious what other people think.
