The gap between the door and floor in public bathroom stalls is a design feature with several practical purposes.

One major benefit is easier cleaning. Custodial staff can quickly sweep and mop without opening each stall.

The gap also allows for emergency access, ensuring help can reach someone in need without damaging the door.

Additionally, it helps keep restroom lines moving by allowing people to see if a stall is occupied without knocking.

The design also discourages inappropriate behavior, as it’s easier to spot unusual activities.

The gap improves ventilation, making the space more breathable and reducing odors in crowded restrooms.

Cost-efficiency is another advantage, as these doors use fewer materials and are simpler to install.

The space can even serve as a delivery point for things like toilet paper if the roll is empty.

While the gap reduces privacy, which some people dislike, the overall benefits—such as hygiene, safety, and practicality—outweigh the drawbacks.

This design is a functional solution that balances convenience and efficiency.
