Faucets that don’t extend far enough

Motion sensors on hand sanitizer pumps
This goes for soap dispensers too…you only touch the dispenser before actually sanitizing/scrubbing your hands. It would be better to put a motion sensor on the door so that you don’t have to touch the handle when you’re walking out of the bathroom. Or require all bathroom doors to open outwards.
