This large single-bowl kitchen sink is made of premium 16-gauge Type 304 stainless steel, the most heavy-duty for residential sinks. It is designed to have tight corners and straight edges with plenty of space to hold pots and pans and everything else. It's easy to move things around in the sink without a divider in place. Measuring 28 inches inside, the sink can be mounted in a 30-inch sink base. The balance of capacity, convenience of use, and fitness for jobs makes it a favorite of many. The sink features a traditional brushed matte finish that allows normal wear and tear to blend into its subtle grains, effectively becoming scratch-resistant. A mirror-highlighted rim adds brightness and sophistication to the sink's minimalist appearance. Heavy-duty rubber pads and coating on underside of each sink bowl muffle the noise of splashing water and absorb condensation due to changes in water temperature. Drain hole is placed toward the rear of the sink so that the under-counter plumbing takes less space and leaves more room for storage. Each Wells stainless steel sink comes with our limited lifetime warranty.
