This Undermount Double Bowl Sink by Empire is made from 16-gauge 304 stainless steel and features a large bowl on the left and a smaller bowl on the right for added functionality. The 16-gauge sinks are undercoated over the bottom rubber pad and four side pads to reduce noise. The undermount sink can be installed under any solid surface and comes with a paper template and mounting clips for installation. The sink measures 31-1/2" wide by 20-5/8" deep overall. Optional bottom grids and strainers for both bowls are also available separately. The sink ships via UPS.
