Shower water /is/ normally collected in grey water systems, but piss would be so diluted as to be a negligable contaminant. A shower uses roughly 70 litres of water. An average human bladder voiding is 400ml, so that works out at 0.57% piss in the grey water collected in a single shower. Negligable - but for fruit trees, a fertiliser.
Our shower drains into the grey water tank and then to our fruit tree irrigation line, so… Of course yes.
I’ve done the maths!
