Public toilets often have significant gaps between the doors and the floor, which can be uncomfortable for users seeking privacy. However, this design choice is rooted in various practical reasons that prioritize hygiene, safety, and security. The gaps allow for better airflow, which helps to minimize odors, and facilitates cleaning, making it easier to maintain overall sanitation in public restrooms.

Additionally, leaving a gap can be a safety feature, allowing personnel to quickly check if a stall is occupied without having to knock or open the door. This can be particularly important in emergency situations, where immediate access may be crucial. Furthermore, the design can also help to deter inappropriate behavior, as the visibility can act as a deterrent to illicit activities in restrooms.

In summary, while the design of public toilet doors might appear to compromise privacy, it actually serves multiple practical purposes that enhance the user experience and safety overall. Understanding these reasons can change the perception of these often-criticized restroom features, emphasizing their thoughtful design in public health contexts.
