This WORKstation DROP-IN topmount sink from Ruvati's Tirana series combines the best of both world: a solid topmount design with a functional workstation: built-in accessories (colander, cutting board and roll-up rack) that slide on the integrated tracks in the sink. Includes a deep stainless steel colander that you can use as strainer. The solid cutting board is constructed of sapele wood - a luxurious hardwood that has a beautiful finish and handles water well. The roll-up rack fits on the top track and is ideal as a dish drying rack. It is constructed of stainless steel bars and a flexible silicone frame allowing you to fold it or roll it up tightly for storage. The sink is constructed from 16 gauge stainless steel, one of the thickest steel available for residential kitchens. Ruvati uses T-304 grade stainless steel that will never rust or stain. The sink features a 1-inch wide and 1/4-inch high rim all around that sits topmount on your countertop. Thick heavy-duty soundguard coating and thick rubber padding on the outside of the sink bowl on all sides provide sound insulation against noise and thermal insulation against condensation. Ruvati's unique 10mm tight radius inside corners offer a slightly curved corner for easy cleaning while at the same time retaining the resolutely modern look. The inside of the sink is finished in commercial grade brushed finish which adds to the beauty of the sink. The slanted bottom of the sink along with 4 drain grooves channel water perfectly towards the drain. The sink comes with bottom rinse grid that protect the sink from scratches when you place pots and dishes. Exterior dimensions: 33" (wide) x 22" (front-to-back).
