I have a colony with a solid "locker room/public bathroom" (3 toilet stalls, 4 communal showers, 3 sinks) all hooked up and always available for use. No shortage of water. However, all of my colonists seem to get their needs bars to absolute zero, continue to work, and risk soiling themselves or fester in their own stink (they used to be in top of it themselves no problem a short while earlier in the playthrough).

Are hygiene needs chosen by work type, like "basic", or are they also limited by schedule, like recreation or "anything"? Definitely seems like an FAQ type of thing for future reference.
