Rated 3.6 out of 5 by 326 reviewers.
Rated 5.0 out of 5.0 by Looks GREAT! Installed this myself. I waited 3 months after purchase to review this item as others with similar sinks said after a few months they looked horrible. Not the case with this sink, it looks great, hasn't scratched or discolored in any way. Goes great with my new countertops. The only bad thing is if you plan on only using some of the 4 holes provided, the blank covers that Home Depot has does NOT fit the holes. I had to snip away the tiny feet surrounding the cover then clear caulk them in from the underside. Still looks good, but a little axtra work for something that should have taken 1 minute. Great buy other than that. September 13, 2011
Rated 5.0 out of 5.0 by High end look & feel Extremely easy installation. Love the feel and color. Self leveling is awesome! April 26, 2013
Rated 5.0 out of 5.0 by Really nice I always wanted a black sink -- it has kept its color and glow - no stains and no scratches so far - its been a year since we purchased this one.. Im very happy.. September 10, 2014
Rated 4.0 out of 5.0 Ideal replacement sink This was a replacement for a cast iron under mounted sink. This sink was easier to mount, because it was lighter and more maneuverable. The holes in Quartz countertop, that was already installed, were off center. I was able to elongate the holes in the sink by using a standard hole saw. I changed out the sink without taking the Quartz counter top off. May 26, 2015
Rated 5.0 out of 5.0 by Black composite granite kitchen sink We really enjoy the looks of the black sink, and the durability of it. (this is the second one we have installed - we put one in our resort condominium 3 years ago, and it has been wonderful in terms of cleaning and resisting scratching, etc) It was easy to install, although the drain holes on the sink did not match the drains on our old sink. One inexpensive plastic pipe kit from Home Depot, and the problem was solved with little extra trouble. May 10, 2015
Rated 1.0 out of 5.0 by poor quality This is described as a composite granite. So I figured it would be like composite countertop materials. I was wrong, this is a fiberglass sink with a plastic coating. It arrived cracked and scratched. Thankfully I was able to return it to a store for full refund! April 21, 2015
Rated 1.0 out of 5.0 by Bummer for us We read the reviews but were optimistic anyways. However we inspected the sink closely before we installed it and discovered hairline cracks in the finish. We were bummed but Home Depot took it back with no issue and refunded our money! April 7, 2015
Rated 5.0 out of 5.0 by blends beautifully with countertop, deep sinks I just installed this sink. The color is deep and muted so it blends well with the countertop and appliances. The only drawback because it's black is if you hard water. There will be white spots from the mineral deposits to clean more often. June 6, 2012
