This Specialty Topmount Round Prep Sink from Houzer is made from 18-gauge, premium grade T-304 stainless steel. The sink features StoneGuard™, an exclusive undercoating specially formulated to reduce the noise of splashing water and clattering dishes. The undercoating also helps to insulate the sink, keeping water hotter much longer. The lustrous satin finish and high-polished finish around the rim of the sink offer lasting beauty. This sink measures 17-1/2" Diameter x 7" H and fits a 24" sink base. Matching bottom-grid and cutting board are also available from Houzer.
