At a resort I've been to a few times, the nightclub area had a cool design. It was a largish round room with sink in the middle. The perimeter was individual tiny rooms with just a toilet. These were all gender-neutral, I guess that's OK because they were actual rooms, having walls and doors. It seems like that gender neutrality would allow for extra efficiency, so that the dense-pack around the perimeter of a single restroom can handle more potential guests. I never asked about how it affects cleaning effort, though. In any case, the original article points out specific OSHA regulations. So it doesn't really matter if there are alternate designs that could work better; you're still stuck in the traditional paradigm, as regulation always acts as a drag on innovation.
