5 Questions from the Community

  • The Kraus KBU11 interior dimensions are 18.75 by 15.75, with an outside of 20.75 by 17.75.

    The spec sheet and installation guide show the interior dimension to be wider than the exterior dimension on the diagram. Will this fit in a 21" cabinet (19 1/2 interior width).

    Can you install the sink in the opposite direction?

  • The Kraus KBU11 needs a 21" cabinet to fit properly.

Product Reviews

Rated 5 out of 5 by from Just Perfect! It was tough to find just the right size sink. It has enough room front to back so you can comfortably install a faucet and soap dispenser and it is deep enough to clean pots and not too deep to waste space in the cabinet below where you store your chemicals. Also beautiful finish. Very happy with this choice.

Rated 2 out of 5 by from Not so much This sink must be meant for people who only run water and microwave in their kitchens. It scratches VERY easily. Manufacturer instructions indicate it must be coddled. Looks good new; after a week's normal use it is scratched & spotted forever.

Rated 5 out of 5 by from Great quality great price Ordering was easy, delivery was timely and everything was as advertised. The only thing I would change is the interior finish seems a little rough but will probably become smoother with use. Also the depth was a little more than I expected. Otherwise I can highly recommend this company and product.

Rated 5 out of 5 by from Right out of the "crate" Wow! I read the reviews and made my selection. Kraus brand/sinks were everything the reviews said. Well packed, nice bags for protection and one of them was even "crated" in a firm box with a lid. Quality is in this brand. I am pleased to have made a great purchase. If you are looking for a "bar" size sink as an extra, this is a bit large/deep. I would choose this for one main sink it is substantial.

Rated 5 out of 5 by from Top Notch Sink at a Fabulous Price! I researched many sinks before purchasing this one. The criteria was a heavy gauge, a good look, and a good price. I was about to settle on another none too enthusiastically, when I looked at Faucet Directs site. And there it was. Adorable! Although a few inches shorter than the norm it is also much deeper which is fabulous. It comes with a grate that you have the option to keep on the bottom, I do because it also is very stylish. The gauge is the thickest you'd want, soundproof, the feel of excellent quality. A nice thunk instead of a tinny aluminum sound. Easily installed by my Corian fabricator this sink looks like I spent $1,000! Highly recommended.
