Public restroom stall doors often stop short of the floor, a design that may look odd but is intentional. The gap improves hygiene, safety, efficiency, and even cost-effectiveness.

Cleanliness is a major factor. “If stall doors extended all the way to the floor, cleaning staff would have a much harder time mopping.” The open space lets tools reach under doors, speeding up the process and ensuring better sanitation.

Safety is another reason. “A door that leaves space at the bottom allows others to quickly notice if a person has collapsed inside.” In emergencies, the gap makes it easier to provide help or even crawl inside if needed.

The design also supports ventilation and efficiency. The opening allows odors to disperse and helps users see if a stall is occupied by checking for feet. This prevents interruptions and keeps crowds moving in busy locations.

Shorter doors also deter vandalism, reduce misuse, and lower construction costs by using less material. While some dislike the reduced privacy—especially compared to European restrooms with full-length doors—North American facilities generally prioritize practicality.

That small gap, far from being a flaw, is a “carefully considered feature” that makes restrooms safer, cleaner, and more functional.
