do you have one of these
Not in my garage. But one of my neighbors does have an actual urinal in his garage behind a shower curtain. He had it installed when he had a downstairs bedroom into a laundry room for his wife.
He's retired and sits in his recliner out in his garage all day reading, then most of the late afternoon and evening watching sports and racing on the bigscreen tv in his garage. Also has a small couch in the garage for friends and neighbors. He's put mirrors in strategic spots so he can see each of the other six houses on our cul-de-sac from his recliner.
The last thing he does every night is cover up his bigscreen and pull his wife's car back in the garage.
