My mind is continually blown by the absolutely horrible designs I witness when I walk in to restrooms in local businesses.
One restaurant has 3 sinks and one hand dryer. The hand dryer is perfectly placed on the wall in a location that requires you to stand in front of 2 of the 3 sinks to dry your hands.
Another has stall doors that swing out, so you basically have to shout a warning before you open the door so you don’t accidentally kill someone.
Another one has stall doors that swing in, but only until they smash into the toilet bowl.
I think the UX pros of the world need to unite and do pro bono work for the folks designing business restroom layouts. Seriously, it’s just pitiful.
