Product Technologies / Benefits:

  • Smart Divide: The basin divider is set to a lower height than perimeter of the sink; you gain the convenience of a single basin sink completely filled, without losing the functionality of a double basin sink. The lower divider also gives more room for working with larger pots and pans providing more access for filling and cleaning.
  • Enameled Cast-Iron: Kohler Enameled Cast-Iron combines the strength, durability, and insulation benefits of cast-iron with the scratch, chip, and burn resistance of a baked, powder coat finish and comes with an exceptional Lifetime Limited Warranty. When these materials are combined it gives the sink or tub the strength to last a lifetime of use. Kohler Enameled Cast-Iron is also available in a wide variety of specialty colors allowing you to truly customize your home.
  • Self Trimming: An Apron Front design that overlaps the “Apron” down over a portion of existing cabinetry. This allows the installation of an Apron Front sink with only minor countertop modification.

Kohler K-6427 Reviews

Rated 5 out of 5 by from Double basin Whitehaven sink in Frost The sink, well balanced in the double sink configuring. I like the lower division construction. It allows me to move heavier items over for draining without bumping the division, thus less cracks and chips in dishes, etc. The color is so lovely, blue but not overly blue and does not leave water spots. Faucets Direct were real troopers in getting it on order for me and standing with me on getting it as quickly as possible and doing all the work of staying on top of the order. Since it was special order, it did take a while to get. I am very pleased with the product and Faucets Direct!

Rated 5 out of 5 by from Beautiful Sink This sink is everything I was looking for - the large capacity of a farm house sink with a separate disposal section for food prep when there are a few dishes in the sink. It's a beautiful statement piece that's gotten more compliments than other aspect of my kitchen remodel. I did get a silicon mat for the large side to avoid staining as per the recommendation of friends with white porcelain sinks. So far I've had it for one month (of vigorous use) and I haven't noticed any dings, scratches or discoloring. Very happy with my purchase.

Rated 5 out of 5 by from Beautiful and sturdy! Aesthetically pleasing and bomb proof cast iron! Didn't like the idea of using a clay or porcelain kitchen sink; great not having to worry about a dropped pan destroying it.

Rated 5 out of 5 by from Love affair I asked my family if it was wrong to "love" my sink! It is great in our 1940's galley kitchen re-do.

Rated 5 out of 5 by from Beautiful! I absolutely LOVE my sink. I cannot wait until our kitchen cabinets are in with the new sink installed. Gorgeous!

Rated 5 out of 5 by from Phenomenal sink! My wife wanted this sink just for its aesthetics, but I was very surprised at how practical it is as well. It's actually easier to do dishes in the sink and it's rock solid, so you don't have to worry about damaging it. It's definitely on expensive side, though, but would do it all over again if given the chance.

Rated 5 out of 5 by from Great product and super fast shipping! I will always go with Kohler cast iron sinks...no chipping, no cracks in the porcelain finish. Some other types of sink you are not able to pour boiling or freezing water or it produces hairline cracks all around the drain. They are also hard to clean. But cast iron sinks last forever and clean up to look totally new. The smart divide is a feature I won't ever do without as it makes maneuvering large pots and pans easy. Build.com shipped way sooner than anticipated, which I was thrilled about!
