No building occupant wants to walk into a restroom and see wet, wadded up paper towels strewn across the floor. Or even worse, step in a puddle of water resulting from overflowing sinks or toilets that have been purposely clogged with paper towels.

In schools, sport facilities, restraurants and retail stores, restroom vandalism is going to happen. But cleaning staffs can make it more difficult for vandals to strike.

One solution is to install hand dryers instead of paper towel dispensers. This way there are no towels to clog fixtures, no external parts to tamper with, and most dryers are built strong enough to resist denting. They are also often installed with special, theft-resistant screws.
