I am personally confused at how much of this sentiment is in this thread.  I've never even considered peeing in the shower as it just seems innately yucky to me, and I'd have thought that would have been pretty common among people (not necessarily the majority, but not uncommon enough for people to believe that everyone did it).

I always go before getting in the shower.

Yeah I've always found these threads equally confusing. There's a toilet right next to the shower in the vast majority of bathrooms. I just use it on the way in or out. Haven't peed in a shower or other body of water unless I was desperate (like swimming in a lake or ocean with no bathrooms or even bushes to piss in nearby) since early childhood. I'd rather not be swimming in my own piss or standing in it.
