Imagine a bathroom where instead of water, everything is piss. Every valve pipes in piss instead of water. You go to the toilet- filled with piss. You take a shit and flush, only for the toilet to be filled with fresh piss again. You go to the urinal and flush it, piss streams down when you flush instead of water. You go to wash your hands and the sink puts out hot and cold piss. You must clean yourself, so you get in the shower. Warm piss comes out of the showerhead, and gets your hair wet. Don’t even think about filling the tub.
