Just close the restrooms and issue each student a chamber pot. That way they can take their $#!^ home with them for recycling at the end of classes. And don't talk about privacy - you threw that away when you said "anyone drop by" about your restrooms.

I wasn’t aware that these toilets/whatever had no doors or locks, so I am not sure about the privacy cavil here.

Replace all bathrooms with porta John’s.
