Mixed bathrooms, mixed showers. There's a process involving a door to the shower room and shower curtains such that you are basically given the privacy you need to get in and out, and change, without running into anyone else. It's basically a knock, 'come in i'm already in the shower', change, get in the free shower, 'ok i'm in', 'ok i'm getting out', change, 'bye', close shower room door type of thing.
Worked great. I actually think the incidents of something like a 'panty raid' or, say, hiding a camera in the ladies' room, are drastically reduced when people are required to act like responsible adults just to get through day to day functions.
