Can you?
I can tell you that both of the bathrooms in my house are gender neutral. What about your home?
I am not concerned with gender neutral bathrooms in my home, since anyone who visits me knows how to behave and what gender they are.
Beyond that, I live alone anyway...
However; in public bathrooms, with certain bird-brained people..they coulld have photos and diagrams,...... even a "scratch & sniff" on the door
and they STILL wouldn't "get it" !
