It works perfectly, it's just more expensive to construct. In some Nordic countries there are very few places with bathroom stalls, they either have lots of single-use bathrooms or completely walled-in rooms (wall from ground to roof, regular door) with a toilet and then sinks outside to wash your hands. Works in shopping malls, airports, schools (from small elementary schools to huge high-schools, I've never seen one with stalls). The only exceptions I can think of that have stalls are amusement parks, some sport arenas and (ironically) IKEA.
