Underbar Sinks are compact, low height units designed to provide one or more sinks under your commercial bar or countertop. This means you can install them wherever you need a sink as long as you have your undercounter or bar plumbing in place. Underbar sinks give your staff a place to fill, dump, rinse, or soak glasses from your commercial bar. Many models include one or more drainboards. You will find most manufacturers of underbar sinks offer single, double, three-bowl and four-bowl models.
