If you’ve ever used a public restroom, you’ve probably noticed “the noticeable gap between the stall door and the floor.” While it can feel awkward or uncomfortable, this feature is intentional. Designers of public spaces must balance privacy with safety, hygiene, and practicality, and the gap under stall doors plays an important role in that balance. It is not a careless detail, but a functional design choice.

One of the main reasons for the gap is safety. As the article explains, “emergencies can happen unexpectedly, and quick access is essential.” The open space allows staff or emergency responders to quickly check whether someone inside may need help without immediately forcing the door open. This can reduce response time and help ensure assistance is provided as quickly as possible.

Another key reason is ventilation. Public restrooms are used frequently, and proper airflow is necessary to keep them comfortable. The space under the door allows air to move more freely, helping ventilation systems work more efficiently. As noted in the article, “better airflow reduces lingering odors and moisture,” which improves overall cleanliness and comfort.

The gap also makes cleaning easier. In busy places like malls, schools, and airports, restrooms must be cleaned often and quickly. The open space allows staff to mop floors without opening each stall, saving time and reducing wear on doors and fixtures. Though it may seem minor, this design choice helps keep public restrooms safer, cleaner, and easier to maintain.
