So many of the illnesses we come in contact with every day, from colds and flu to food-borne pathogens such as E. coli, can be controlled by frequent hand washing. Having a portable sink at a worksite, county fair, daycare facility or school allows workers, attendees and children to stop and wash their hands whenever the need arises. With a portable sink there's no need to go inside and find a bathroom. The sink is self-contained and ready for use.
Setting up an entire bathroom is simply not an option in many different places. The organizers of a weekend art fair, for instance, probably don't have the time or the budget to construct or rent a suitable facility. They can, however, rent a bank of portable toilets and set up a few portable sinks for their patrons to use. Portable sinks can also be used at job sites and other locations where it simply isn't practical to provide full bathroom facilities.
If you're planning an outdoor party or cookout, consider the convenience of your guests, as well as your own convenience. Having a bunch of people streaming in and out of your house to use the bathroom can be quite intrusive. Setting up a portable toilet and sink can prevent those problems without inconveniencing your guests.
Portable sinks allow businesses to remain compliant with hand washing regulations that govern companies that prepare and serve food. Caterers, food cart operators and owners of portable food outlets must provide their employees with a convenient way to wash their hands to remain compliant with applicable laws. Portable sinks provide hot and cold running water, making it easy for workers to wash their hands often throughout the workday.
