It's different, Petronski. When you pee in the shower it just flushes right down the drain, unless it drains slow, in which case you're standing in it for a little while. Hope you don't let anyone in your shower because if you do I guarantee it's been peed in.
Actually, I just go roll around in the dirt and then brush off. Seems to clean me up just fine.
Also, I knew this guy, Mexican, who never seemed to have any TP. I asked him why and he said he preferred the shower, that he felt cleaner afterward.
