do people have installation problems?

Had leaking problem after instalation. Had plumber come and he said he fixed it half later leaking again. Seems the holes in bottom of basin are to large. Other sinks we looked at the hole in bottom of basin seems to narrow as the one we had before. We are remodeling Kitchen thats why we changed color.

Rated 2 out of 5 by from scratches too easily This is a beautiful sink, just what I wanted to finish off my kitchen remodel. Unfortunately it scratches too easy. I do a lot of baking and my baking pans scratched the sink divider while I was washing them.

Rated 4 out of 5 by from I am loving this sink I ordered this sink in white and also ordered the Kohler Forte faucet and just had both installed. The sink is very roomy and deep, and has a nice, shiny finish. Please note the recommended cleaning is with a soft rag and 409 or Windex - no abrasive cleansers OR pads/sponges at all (to remove a stain a bit of Bon Ami or Barkeepers Friend only). Upon the manufacturers suggestion, to keep heavier pots and pans from scratching the sink, I did order the stainless steel basin rack for the bottom of the left sink. I keep a small stainless dish strainer in the right sink for dishes that I wash by hand. Let me tell you, this rack has made the sink a perfect joy for me. Not only does it protect the bottom of the sink but it allows for easy-as-pie washing of fruits and vegetables without dragging out the collander. You can just put your produce on the rack and nothing ever touches the bottom of the sink. Broccoli, cauliflower, romaine lettuce leaves, grapes - all wash quick and easy. And with the pull-out Forte fauchet, you can clean, rinse, and drain away debris all in one step. There are a few small cons: There is not much room on the back edge of the sink (see picture) for a hand soap and dish soap container off to the side and that is about it. Also, I notice the center divider can take a little wear from knocking it with pots/pans. I noticed a comment about this in another review. I may purchase one of those small, plastic, bottom-of-the-sink protectors and drape it over the center section and see how that works. All in all a beautiful sink, but you do need to take a few small steps to protect and maintain the finish.

Rated 2 out of 5 by from Not as advertised! "Scratch-proof" my foot! Our sink was installed (professionally) less than two weeks before MAJOR scratches (white underneath the black finsh) began appearing! We had used NO abrasive cleansers. Nor had we even cleaned the sink yet! Now it is looking like a 10 year old sink already. I fully intend on going directly to KOHLER with this compaint. Be wary of purchasing this sink. It looks great on the Home Depot floor, but is not at all functional! It will look fantastic in your kitchen too.....that is, UNTIL YOU USE IT!

Rated 1 out of 5 by from Still not the usual Kohler quality We used the cast iron cleaner sample that Kohler was so kind to offer. This product is designed specifically to remove scratches caused by pots and pans hitting the surface. The cleaner did nothing to remove the scratches and stains. Our beautiful sink is still scratched, stained and pitted.

Rated 1 out of 5 by from Not the usual Kohler quality. Beautiful, roomy sink. BUT ... the surface began showing pits within a month of installation. The porcelain scratches very easily and the scratches cannot be removed.

Rated 5 out of 5 by from Awesome sink! Well made and has been very durable. Hard water can be a bit of a challenge due to it being black. If you stay on top of it though it isn't a problem. I would highly recommend this sink. It is super heavy though, get help putting it in.

Rated 2 out of 5 by from Disappointed with product After three perfectly satisfactory previous purchases of Kohler cast iron sinks we understandably chose another to add to our recently purchased home. After the painless process of choosing and purchasing the sink online we were surprised to receive a poorly packaged and consequently broken sink. A replacement was ordered and arrived undamaged. Approximately ten days after installation noticeable scratches and minor cracks appeared in the finish. Considering the fact that my wife and I are nearly OCD in our care of our kitchen, it is obvious to us that the finish on this sink is not up to even mild use. Even the slightest contact between this sink and a pot or pan leaves a permanent mark. Considering the number of great products we have used from Kohler we are greatly disappointed in this product and would not recommend it.
