I always have a strong ban on sinks and bars in all of my houses, and refrigerators come out of the family inventory only when they can be used under strict supervision.
I tend to make households with athletic sims only (so they won't get fat.) So all I have to do is take my eyes off of my sims for a half of a second, and there they go self-destructing their bladder again...... it's a nonsensical problem to ever have to deal with, it drives me crazy, and I really don't want to be that frustrated every time I try to play. So I don't.
I'm happy to report that my game is a much better place without them, but of course I would much rather be able to just have a normal house.
