I figured I am in garage, and while in the garage working on my cars I am grubby, and last thing SWMBO would want is me trekking through the house. I thought I should add a small bathroom in the garage.
During design I realized, I was just slightly lower than crawl space. But, I did have the fall for a sink and could install one with minimal plumbing. But installing a WC would require a lot of digging.. so a full bathroom was out.
Then I thought, I tend to be drinking beer while in the garage, which means I usually don't have to do anything more than take a leak and well.. and there did seem to be room in the storage closet.
TA DA !! An Urinal in a garage thought was hatched, and born.
BTW Think every guy that spends any amount of time in his garage should have one.
