Durable sink for kitchen stands up to impact, scratches, and shock, and is colored all the way through to resist fading. Deep sink with gently sloped bottom promotes easy draining and has ample space for large cookware. Installation-ready kitchen sink comes with drain assembly, towel, hardware and template. Available in drop in sink design that installs with any countertop material

Review: Really like the sink. Nice and deep and so far easy to clean. Plumber said he wasn’t cracked on the gasket for drain but it works.
Review: The only down side is typical for all under mounting units in that is very deep in the cabinet, leaves short space under or beside the drains for water distribution valves, led drivers, storage items and waste bins. I got it All in but it took careful space planning and sequencing of installations to get it all to fit in a 36” wide cabinet.
