Oh, c'mon. Salem has a money tree, so of course, their bodily functions are just magically unneeded, thus no need for food. Or bedpans, or anything else soap writers consider "indelicate" matters. Oh, sure, viewers still wonder how the heck some things are managed. Is there a toilet in the corner, (we never see it) turn your back! A sink to wash one's hands? What about toilet paper? paper towels. Do they dry hand, if they can get them wet, on their clothes? No showers, of course.
