The Planar 8 Single Basin Undermount Stainless Steel Kitchen Sink is made of smooth, Grade 304 (18 percent chromium, 10 percent nickel), 18-gauge stainless steel, with sound-dampening pads and Franke’s silky luster finish. These undermount sinks measure 17 inch from front to back to enhance countertop work space without compromising sink functionality. The drain is placed in the rear of the unit so that drainage piping does not crowd the space inside the cabinet beneath the sink. Keeping a Planar 8 sink bright and clean is easy given the thoughtful design. Unlike the zero-degree radius corners of other hand-fabricated kitchen sinks, the new Planar 8 is handcrafted with a tight, 3/8" radius. That minimally curved corner makes this new product much easier to maintain.
