32” Undermount 18-Gauge Stainless Steel Single Bowl Kitchen Sink

Designed for universal appeal and long-lasting durability, Kraus® Premier™ Sinks feature rounded corners and sloping sidewalls that create a soft transitional look in any kitchen. Undermount installation makes cleaning easy, with no exposed mounting deck to trap food and debris, creating a seamless transition between sink and countertop. Heavy-duty 18-gauge construction offers lasting durability, with resistance to dents and damage. The high-capacity single bowl sink creates an uninterrupted work surface with ample space for large cookware and stacks of dishes. Thick NoiseDefend™ sound dampening pads help absorb noise and vibration for an ultra-quiet experience when the sink is in use. Perfect for busy kitchens, the commercial-grade satin finish is wear-resistant and not prone to corrosion, stains, or rust. Sweeping rounded corners make this sink easy to wipe clean, and help reduce build-up over time. A sloped bottom improves drainage so that your sink remains drier after each use. The installation-ready sink kit comes with a protective stainless steel bottom grid, cut–out template, and matching drain assembly for a clean look.

          We recommend avoiding cleaners with harsh chemicals like chlorine, bleach, ammonia as these items can cause damage to the sink surface.

      How can I remove scratches from my sink?
          Scratches are inevitable in any sink material, including stainless steel. These are merely usage scratches over time, these scratches will become uniform with the sink's grain and blend into the overall finish of your sink with proper cleaning. Most minor scratches can be softened with a fine (white) 3M Scotch Brite pad, or 3M Scotch Brite Natural Fiber Non-Scratch Scour Pad, accompanied by a deep cleansing agent such as Bar Keepers Friend.

      Can stainless steel sinks rust?
          No. Typically, when red spots appear on a Stainless Steel Sink it is simply surface discoloration due to iron and mineral deposits in the water. This is usually taken care of permanently with a stainless steel polish and/or cleaner when used according to the directions of the cleaning product. Products such as Bar Keeper's friend and a fine 3M Scotch Brite pad are both great options.
