What is a prep sink?
Prep sinks are also often referred to as bar sinks. They’re generally smaller sized sinks, measuring 15” wide, and are available in square or round shaped options. They’re designed for home bars or entertainment areas and are used as an extra sink for the active home.
When it comes to compatibility, or where you can install a prep sink in the kitchen, top-mount and undermount bar sinks are compatible with most countertops. Installation is simpler for prep sinks than for most other ones, and they come in a variety of shapes and sizes.
