One of the best examples of this is a hospital. While most hospitals have scores of sinks, a hospital by definition is a large number of sick people in one building. This requires severe and strict sanitation guidelines to prevent the spread of germs, bacteria, and disease. Portable sinks are a one time cost, do not require costly and disruptive behavior like drilling out a wall for plumbing in a hall full of doctors and nurses rushing helter skelter to save people’s lives, it simply requires opening the package and setting the portable sink down, then filling it with water. You can never be too sanitary, especially in a hospital. Another place that cleanliness is very important, but is not always present, is in a school. Recess is the part of the day where children who have been cooped up in classrooms eagerly run outside to play, getting themselves into all kinds of icky things. They eat snacks and get food on themselves, play in the dirt, pet the dog walking by and even catch bugs. Who knows where they’ve been? A portable sink is an easy solution, it allows a teacher to simply place a portable sink outside of the door after recess and ask each child to rinse off their hands with soap. This can do wonders to prevent the spread of disease and generally have a cleaner school, no matter what age the children are. (Though you may have a tough time convincing a bunch of high schoolers to line up and wash their hands.)
