Earlier quoted context omitted.
What's the issue with the dryers? You use them to dry already-washed hands and the dryers themselves aren't very close to the toilets.
That assumes everyone thoroughly washes their hands, which is unlikely. Dyson hand dryers, specifically, always have a nasty puddle of water at the bottom of their drying "crevice" in busy bathrooms.
I don't know how much that's changed, but I wouldn't expect the change to be particularly meaningful, sadly.
