Cubicles are very often SMALLER than normal public cubicles. With luggage it is a performance trying to prevent baggage getting 'wet' on the floor, bumping into the bowl or dropping items. Who would have guessed that people in airports would have luggage?

Therefore cubicles should be large (similar to disabled) have a raised grid or shelf up off the wet floor, plenty of hooks and preferably a small handbasin & paper so you can wash and dry hands immediately before handling luggage (so not putting bacteria straight onto your handles).

Urinals should have hooks on the wall and a DRY high shelf in front plus adequate space between bays.

Doors should be designed so you can get in and out without touching disease-spreading handles - e.g. washroom has an "in" and an "out" door that opens in your direction of travel and has no latch and cubicle doors have some form of push- release from the inside.

Ideally there should be a small number of trolley-traps so people can enter with their trolley, dump, wash hands then leave. The exit door to open much as a fire escape by pushing the trolley against it.

If one is caught with an urgent call - "that cannot be recinded, not even questioned" - when alone with a trolley full, one is in dire straights.
