I don't care about the drain. I don't lick the drain. Rarely come in contact with it.
I refuse to talk about nastiness. I need an expert to comment but my mom is probably asleep. I know of no other expert.
The coating of urine has no more affect on the hygiene than what comes off your skin. Yes, you need to clean the tub often. But this might be a purely human problem. We are constantly around bacteria and go thru so many things to avoid them but never avoid them. You can scrub your skin in betadine but will never get rid of bacteria. I believe our bodies have effectively adapted to living in bacteria. Not that I want more but in these times, we have to start thinking about how our living effects the entire world. Water is scarce in many parts of the world and I could make an argument that peeing in the shower would create less waste, use less resources and lower the price for good drinking water with little risk. One less gallon flush for the day. You hold less than 200cc of water in your bladder and
use 1-2 gallons to flush it away. It's about as sick as buying bottled water for $1-$2 when the city gives you a few thousand gallons for pennies. We are all wasteful but I don't think a few pee germs, which comes from your dirty penis or dirty vagina, not from the pee, should have too much effect on the thick skin of your feet. Again, it's an area you are there to clean anyway.
That argument does nothing to address the way you inappropriately label the pee as unhygienic. i assume you are talking about bacteria. Unless you want to correct my assumption, then now would be a good time so I don't go off on a rant.
