Clarke’s self-rimming, high-gloss Sinksations™ sinks are so beautifully engineered that even the underside is superior to other sinks. These state-of-the-art acrylic sinks feature a patented SaniShield® underside surface that is clean, non-abrasive and much nicer to see under your sink. In addition, Sinksations sinks include exclusive L clamps for quick and easy installation and a hidden gasket for an airtight fit against the countertop.
