We were camping recently at a state park in PA. There were 3 different rooms in the shower house: Women, Men, and Unisex.
I was tempted to use the Unisex because I also figured that would be the least used and, therefore, the cleanest. But, as a woman, I was not going to put myself in the possible situation of being in there with some strange man.
Aren’t “family” restrooms typically a “one-holer” with a lock on the inside?
