I certainly know it's different. I was just asking if these people saying urine is harmless would thus have no problem peeing in their own bathtub.

Well, it doesn't spread the same sorts of germs as fecal matter (hepatitis for one), but I can tell you I'm not too crazy about public hot tubs for that reason. I had some friends who had one and after having a party they found tomato peelings in the filter.

I've noticed on long runs that if I had to pee at the start I sort of stop needing to after I work up a good sweat.

With all due respect, the difference between peeing in a shower and peeing in a bathtub crosses several orders of magnitude.
