Rated 4.7 out of 5 by 38 reviewers.
Rated 4.0 out of 5.0 by Beautiful sink! This sink is a vast improvement over our original stainless steel one! It is more than twice the depth and has a beautiful matte cream color. I was worried that a light colored sink would stain easily but we have had no problems. Even with the three big reds: beets, bbq sauce, and pasta suace. The only issue we had was that the instructions provided for installation were not very clear (small list provided in the corner of the cut out template) and appeared to be for a different sink model. Also, the instructions provided very little clarification on how the clamps were designed to work. With a little intuitive thinking we were able figure it out and get the sink installed.

Rated 2.0 out of 5.0 by Not what I though it would be. WE FIND IT STAINS EASY AND NEEDS TO BE CLEAN AFTER EACH USE. May 19, 2015
Rated 5.0 out of 5.0 by First time I have ever had a Composite sink, I love it. Very light weight, WON'T SCRATCH - Yeah! I'm looking forward to many year of enjoying it! The Composite sink is light weight and won't scratch. I was able to get it in the color I wanted and at a much more affordable price. It has been installed as an under mount sink with the Granite we purchased. It looks wonderful. October 14, 2014
Rated 5.0 out of 5.0 by Great sink This sink is beautiful...looks amazing! Deep bowls make it so functional and the scratch/stain resistance is incredible. A perfect match to my other bisque appliances. July 30, 2006
Rated 1.0 out of 5.0 by Hairline crack in the basin I was under the impression that Blanco was a quality brand and that the composite material was very tough and durable. However, after the sink was professionally installed, I discovered a hairline crack in one of the basins which seems to slowly be growing. This is extremely disappointing given the hefty price.

Rated 5.0 out of 5.0 by Beautiful Sink - Makes Our Kitchen We ordered online and the sink was delivered to our door via UPS three days later! Packing was excellent and the sink arrived in perfect condition with an installation template, cleaning instructions and clips for mounting. I had much trepidation about punching out the knockouts for a soap dispenser, etc but, as long as you gently use a BALL PEEN hammer, it's easy as pie... no problem at all. Sink went right in and it looks fantastic. Truffle (medium gray) is a great color and the depth of the sinks is really nice. I know others have had concerns about these sinks but our experience was positive and the sink has been trouble free. April 7, 2015
Rated 5.0 out of 5.0 by Love this sink! I love this sink. It was installed 6 weeks ago and I've found no issue with it. Our countertop contractor installed it as an undermount as part of our new countertop installation, so I cannot comment on the ease of installation. Although it is a matte black finish, it has small sparkles in it which really look nice. It has a soft feel to it, not as hard as our previous ceramic sink. It almost feels as if a glass would not break in it, although I haven't had the chance to test this out yet! It does show some water spots on it when it dries, but I don't see this as an issue. I am constantly cooking and using the sink, so I don't expect it to be perfectly spotless at all times. Our neighbors had never seen a composite granite sink before and were impressed with its look and feel. The picture attached shows how it looks dry and wet, although the reflection in the pic takes away some of the beauty. It is much nicer looking than in the picture. December 27, 2012
Rated 5.0 out of 5.0 by LOVE IT! Love my new sink! It is very nice looking, cleans up very nice. Will be so nice not to have to use bleach to clean this like my old cast iron sink. February 11, 2014
