Think the gap at the bottom of the door is annoying? Actually, it plays a discreet but useful preventive role .
Solid doors, all the way to the floor, can create an enclosed space conducive to excesses: damage, consumption of illicit products, inappropriate behavior . The openness reduces this impression of total isolation. It makes the place more « public » and therefore less attractive to people looking to linger or hide there.
Better ventilation… and therefore more hygiene
We don’t always think about it, but in an enclosed space like a restroom, ventilation is essential. Those small gaps at the bottom of the doors allow air to circulate, which limits unpleasant odors and helps keep the space healthier and more breathable .
It’s a bit like leaving a window ajar: it encourages air renewal, which is essential in busy places.
