Dude, everyone pisses in their tub- most people do it during their shower so it just washes down. Anyone who pisses in their tub while taking a bath is just plain sick. If you just piss in the tub instead of the toilet, you are saving water, but you'd also save water by putting a fucking urinal in your bathroom!
If you'd put up the funds to expand and repipe the loo, I'd think much more highly of you!
you are basically washing yourself in piss
I've pissed in the shower a few times.
If you had done a little research you would of learned fresh pee is sterile; that means it's actually cleaner then the water entering from the faucet.
