How much fun is that! Reminds of years ago when I had a cottage and I got fed up with the septic system being flooded with beer flushes so I had an outhouse built for the pleasure of pissers. Used a lavatory sink including faucets like yours for the urinal, put a towel bar for the unsteady and a mirror above that. Fellows could check their grooming while peeing and then not use 5 gallons of water to flush. And yes, I had hand washing gear there too.
What are all those things you've planted? Love the photo of the cats! There's a bar here that used to have a patio/garden with a bunch of sinks and bathtubs as planters. I have photos around here somewhere.
