You never know!
Anyway, this is a tuning mod that makes bladder failure drop hygiene by 20 instead of a full 200. Why? Shower in a can is stupid and the only reason it exists is because you can't pee in tombs. So now you can wet your pants in tombs all you want without so big of a deal. Any normal person would just pee against the wall anyway, so I don't see it as cheating.
Plus I use Pescado's joke Incontinent trait sometimes and this makes it easier(yet still a bit of a pain) to have a sim who pees themselves all the time.
