When you are expecting high traffic at your work or event site, four is a perfect fit. The Four-Person Sink Model is the most compact four-person sink on the market. It fits small spaces but handles large crowds with a 20-gallon capacity. It will fit in most portable restrooms for ease of transportation. Four taps allow up to four guests to wash their hands at once. Like the other models, it comes with soap and paper towel dispensers. (NOTE: Paper Towel & Soap not included) A great choice if you are looking for a highly portable model, as it can easily be moved and refilled by a single person. This flexibility makes it ideal for construction sites.
