> I'd imagine that most couples would still want to be able to close a door when they're on the toilet.

Right?

My wife and I don't use the toilet in front of each other. Even when we lived in an apartment with only 1 bathroom. You gotta use the toilet while one is showering? You can hold it.

Even when I'm home alone and don't expect her to come home any time soon, I close the door. I just feel so exposed with the door open. Even when I lived alone, I'm pretty sure I would close the door.
