An Elkay Lustertone sink looks as great on day 3,000 as it does on day one. Our signature finish is handcrafted with a rich, uniform grain that adds to the beauty of the sink. Light scratches, which occur with everyday use, naturally blend into the finish with time. REPAIRABLE FINISH: Finish is scratch resistant to heavy-duty use. Deep scratches are repairable. Lustrous grain reflects light evenly for high shine. DROP-IN INSTALLATION: Sink is designed for drop-in installation to make the sink a focal point of your room. SINGLE BOWL: Bowl gives you uninterrupted space for washing and stacking dishes or other household tasks. 18-GAUGE STAINLESS STEEL: Highest quality 18-gauge thickness and Type 304 stainless steel for lasting durability, performance and lustrous beauty. QUIET: Sound-deadening pad(s) minimizes sound and vibration for a quieter time at the sink. U-CHANNEL INSTALLATION: Mounting clips placed inside the channel before installation mean less time under the sink for an easier install. LARGE CAPACITY: Straight sidewalls give the sink a flat bottom and offer more usable space for stacking, soaking and washing dishes, easy to clean. EXTRA DEEP BOWLS: High-capacity bowls offer more room inside for stacking dishes, filling stockpots, and handling large baking sheets and roasters. MADE IN THE USA: This Elkay product is proudly made in the USA. DRAIN OPENING: Sink drain opening measures 3-1/2".
