Why don't houses have urinals in them? I'd find them to a big convenience. Esp. with 2 guys living in the house - The lid can always stay down. No missing the target, less gross to clean. Sure beats pissing in the sink. Although I do hate public urinals. And 'urinal cakes' are gross, but I'm sure they can be improved.
What about a drinking fountain? No glasses to wash for that "quick sip" would be great. What's not there to love?
