Rated 4.4 out of 5 by 56 reviewers.
Rated 5.0 out of 5.0 by Great product I just installed this new sink and am more than pleased with the look and quality. I just looks great and I really liked the RIMLESS installation - just set it in silicone caulk - no attaching those nasty things that make you go up under the counter and such. I'm a little skeptical at how it will wear in daily use but we will see what will happen. I did make one mistake in that I bought the fawcet after I had ordered the sink. The fawcet was a one hole design but I had already ordered the sink with 4 holes. Next time, get your fawcet first, then order your sink. July 20, 2006
Rated 5.0 out of 5.0 by It is a very nice looking sink. We had this sink installed in our laundry room. It looks great and is the perfect depth. December 19, 2014
Rated 3.0 out of 5.0 by PLEASE READ I have to say that Thermocast was the best customer service I have ever dealt with! I had a problem with the finish on my sink after having it for only about a year, which is why I gave only 3 stars on the product, however, when I called customer service they told me it had a lifetime warranty and they would replace it no questions asked! I was amazed at how simple and easy they made the process for me. So while yes I was sad the the original sink began to crack in the finish, I believe the value of a company that will stand by its product like thermocast did is worth a great deal. May 14, 2012
Rated 5.0 out of 5.0 by It's a conversation piece I'm sure you know that Coca-Cola red is probably not the most popular color for a kitchen sink. However, that is precisely why I bought it.... I'm a Coca-Cola collector and it was perfect for my Coke kitchen. I also purchased a red faucet from Home Depot and they are both beautiful. The sink was easy to install, according to my husband and his friend, and it is easy to keep clean and shining. The price was great and the ordering online and shipping was just as promised. I would recommend this product. June 26, 2014
Rated 5.0 out of 5.0 by Attractive, sturdy, just what I wanted. Needed a deep sink for my kitchen and wanted one in black to match appliances. (I'm so over granite countertops and stainless steel appliances.) The sink, ordered at the store, arrived within a few weeks and is perfect for my needs. It looks wonderful with my oak countertops. I recommend it. February 28, 2015
Rated 5.0 out of 5.0 by Happy, as always, with Home Depot I am very happy with the quality of this sink for its price. And I love the depth of it. I like it much better than the shallow double sinks I used to have! December 17, 2014
Rated 1.0 out of 5.0 by worst sink ever! had this for just over one year. it looked great for about 6 mo. now, the finish is gone and it has deep pits and discolored. going back to stainless November 25, 2014
Rated 4.0 out of 5.0 by good product, easy install I like the sink very well, good material, workmanship. The only complaint is there is just 1/4 inch base to glue the sink to the counter top. It would have been better to have at least 1/2 inch of surface for a better bond. June 11, 2011
