Rated 4.6 out of 5 by 28 reviewers.
Rated 5.0 out of 5.0 by This is a beautiful and very functional sink I spend a lot of time in the kitchen and love to cook so I was looking for a sink that would be an asset to one of my favorite pasttimes. This sink is everything that I wanted. The large basins allow for clean up on one side while doing food prep on the other. I read many of the reviews where it was mentioned that the sink is scratched after a year or so of use. I decided to protect my investment by buying the stainless steel sink baskets that Kohler makes for the sink. They protect not only the bottom of the sink but your dishes. I also bought a sink saddle product called "Pebblez", which fits over the divider. This product, which is attractive and inexpensive, can be trimmed so that it fits perfectly to the lower height of the divider and provides a very good cushion. Now this very functonal sink will keep its beauty. March 18, 2013
Rated 2.0 out of 5.0 by Chipping at Corners We have had this sink for about 2 years. It marks, scratches and chips like any enameled cast-iron does, and cleans easily with a sponge and Comet, Bartenders Friend, or the like. The design is excellent, as is the appearance. The disposal runs very quietly with a minimum of vibration thanks to the rigidity and mass of the sink. We have it dropped into a Corian counter top, installed per instructions. My disappointment is in the corners where the sink meets the counter top. The enamel is chipping off from the bottom edge, as if the corners were not properly designed to bear weight. Unfortunately the warranty is only one year. July 23, 2012
Rated 5.0 out of 5.0 by This is the perfect sink. The smart divide gives the advantage of 2 separate bowls and yet the low divider gives the advantage of one wide bowl. Although the overall sink is the same size as the 2-bowl stainless it replaced, it appears so much bigger. Maybe it is the low wall of the smart-divide or maybe it is the visual attractiveness of the white color. Couldn't be more pleased. December 22, 2012
Rated 5.0 out of 5.0 by I love this sink I have had this sink for two years now and am just about to purchase one for my mother for Christmas. It is a wonderful sink because of the dropped middle divider, and the sink is plenty deep which was something I was worried about. I have a large family so a lot of dishes go thought this sink and it, like any sink can need a really good cleaning from time to time. What I do is fill both sides with water and add about a 1/2 of a cup of Clorox bleach to the water and let it stand over night. It looks good as new in the morning. For the black marks that get on it from stainless steal pans I use Zud. It takes a little elbow grease but they will come off. I have no complaints about this sink. December 12, 2010
Rated 5.0 out of 5.0 by Great sink This sink is very unique with the low divide, which makes it easy to move pots and dishes around in the sink. I have the white cast-iron and it looks nice. Some have complained about scratches, but life happens and you can't expect a cast-iron sink to be unscathed over use. Keep in mind cast-iron is super heavy (this is over 75lbs), but I love the look and will take it any day over a stainless steel sink. If you love using something very functional, this sink will be great. June 26, 2012
Rated 3.0 out of 5.0 by Scratches to easy We have had our sink for about two years now and and I must say that it's just not as durable as we had hoped for. This may be typical for this finish as this is our first cast iron sink. It's still a great design and very functional especially for those that cook alot and have large pots/pans. Strongly recommend purchasing kohler cast iron sink cleaner or cerama bryte cooktop cleaner, both work great at getting the residue out of the scratches. January 21, 2010
Rated 5.0 out of 5.0 by It's gorgeous!!! I don't remember ever being excited about a sink before, but now I am. This sink is absolutely beautiful. I'm amazed at the difference the extra depth makes, and the "smart divide" is just the best. How nice to soak pans without them being slanted into the sink. How wonderful to wash my huge wok and large baking dishes without drowning the countertop. I know that stainless steel is in vogue right now, but it doesn't appeal to me. Styles change over the years, but white cast iron is a classic. If I sell my house 5 or 10 years from now, stainless may have gone out of fashion, but this sink never will. I purchased a Price Pfister faucet in Tuscan Bronze. The combination is a hint of elegance in my country kitchen. I simply love it. June 23, 2010
Rated 5.0 out of 5.0 by It's a Kohler This kitchen sink is beautiful. You've heard the expression "everything but the kitchen sink"? Now I know what it means: you can take everything or anything in the kitchen, but not my Kohler kitchen sink. Not only is it beautiful in style and form, but it's roomy and oh so functional. Easy to keep clean and sparkling, it's the focal point of the kitchen. I've even had offers to wash dishes, just so someone can try it out. You can't beat that! April 24, 2007
