Made with durable T-304 stainless steel, this undermount sink will stand up to constant use, and easily handles your toughest kitchen tasks. Commercial grade satin finish makes cleanup as easy as wiping the surface with a damp cloth. Since thicker steel means a stronger, more dent-resistant sink, this model is made from TRU16 real 16-gauge stainless steel, always 1.5mm thick. NoiseDefend™ soundproofing technology ensures a quiet kitchen experience by eliminating noise and vibration when the sink is in use. All Kraus stainless steel sinks come with free kitchen accessories, including a fitted stainless steel bottom grid with non-scratch rubber bumpers.

Customer Questions & Answers

I have what is considered a 33" wide cabinet, but the plywood on each side of the cabinet is 1/2 inch on each side. That means that the inner space inside the cabinet is actually 32" wide. Is that enough to have this sink mounted? I certainly hope so, because I love the sink.
Asked by: Tishie
HI Tishie, The KBU21 measures: Sink Length (inches) 29.13 Sink Width (inches) 19.50 We recommend a minimum cabinet size of 33" to ensure there is enough room for the mounting hardware that arrives with the sink. A 32" internal size should still work fine. Thanks

Which would you recommend putting the insinkerator on since you have the stainer? Are the sides interchangeable?

Example: I have looked at the manual and can't figure out what I did wrong.
Asked by: Ratman
Hello, Thank you for your inquiry. There is no side recommended for a disposal unit, that is completely up to you. Please let us know if you have any other questions. Thank you, Kraus USA

If this won't fit in a 30" cabinet what models do you suggest that will fit?

Asked by: TCC
Thanks for your inquiry. Our KHU24L would be the closest sink we have to accommodate a 30 inch internal cabinet. Thanks

Can an under mount be used with a laminate top?

Asked by: Gator
HI Gator, Our sinks are best suited for solid surface counter top materials like granite, soapstone, marble, or concrete. Not well suited for laminate or tile counters, which have too many weak points along seams and grout lines to support the weight of the sink. Thanks

Rated 5 out of 5 by from Easy purchase The sink; was ok, but originally when they gave me the price, it did not include plumbing. I was surprised when I had to pay more.

Rated 5 out of 5 by from Endurance and Elegance Wrap Up in One. Excellent Choice I often suffer from buyers remorse when remodeling. This is one product I knew was the right choice. The look, weight, and finish exceeded my expectation. The grates which come with the sink is an added bonus in protecting the sinks from scratching. Most of my stainless steel sinks after a month of use usually have several scratches, not this one. So far so good after three months. Krause 16 gauge sinks are an excellent option for those of us who use their sinks and kitchen often and looking for products with endurance and elegance.

Rated 5 out of 5 by from Nice Sink Product shipped quick and in solid packaging. Looks great and the accessories were a bonus. I would definitely recommed

Rated 5 out of 5 by from Looks great-seems very durable-love the bowl sizes too! This is going in our little cabin, possibly will rent out in the future. The sink looks great (satin finish), the SS gauge is heavier than most (16 ga); the accessories are a nice bonus! Our contractor really liked the sink too! Both bowl sizes are wonderful, esp for a narrower sink-having the deeper bowls helps. Great quality for the $ spent!

Rated 5 out of 5 by from Quality sink Great product that was packaged so good that a two story drop would protect it. Too bad that we had to go to the US to buy it, Home Depot Canada does not sell this sink.
