If you’ve ever used a public restroom, you’ve probably noticed it: the stall doors don’t go all the way down. At first glance, it feels strange—even frustrating. The gaps can make people feel exposed, and many assume it’s nothing more than a way to cut costs. But the truth is, that open space serves multiple important purposes. From safety and hygiene to convenience and accountability, the design is far more intentional than most people realize.
Hygiene Comes First
Public restrooms see hundreds, sometimes thousands, of visitors daily. Keeping them clean is no small task. That gap at the bottom of the door allows cleaning staff to mop, disinfect, and sanitize floors without having to enter each stall individually. This speeds up the process and ensures that germs and spills don’t linger in hard-to-reach corners. A full-length door may feel more private, but it makes thorough cleaning slower and more complicated.
Safety in Emergencies
Emergencies can happen anywhere, including inside a restroom. Someone might faint, have a medical episode, or even get locked in by accident. In those moments, the space at the bottom of the stall door can be life-saving. It allows others to quickly spot if someone is in distress—and if necessary, crawl under to help. When seconds matter, this design can prevent tragedy.
