Product Technologies / Benefits:

  • 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.
  • Apron Front: Kohler apron front sinks have a stylish panel in front and are available in both drop-in (also called tile-in) and undermount configurations. Sometimes called a "farmhouse sink", this beautiful style evokes the charm of a traditional kitchen and can be installed with only minor modifications to existing kitchen cabinetry and countertops.
  • Self-Trimming: A style of apron front sink design in which the apron overlaps a portion of the existing kitchen cabinetry. This allows the installation of an apron front sink with only minor countertop modification.

Kohler K-6488 Reviews

Rated 5 out of 5 by from Kohler Farm sink I love this sink. Looks beautiful in our newly renovated kitchen. A dish pan give you plenty of room If you want to hand wash things. There is room to rinse without having to use a drainboard. Very nice company to deal with.

Rated 5 out of 5 by from Great product, greater customer service I bought the smaller size first, when I got it I realized the the larger one was what I needed. Called customer service and he arranged the order for the new one and gave a return authorization. Great service and the sink looks great. Would highly recommend build. com

Rated 5 out of 5 by from Fast Delivery I ordered this product on a Friday night and it was delivered by the following Wednesday. The freight company called to confirm delivery and when it arrived it was packaged very well. We now have the sink installed and it is beautiful. A great option to the deeper apron front sinks and very little work had to be done on the cabinet to install.

Rated 5 out of 5 by from Excellent Wow, what an upgrade from a double basin sink. Easy to install and looks fantastic. The hard part was retrofitting the granite!

Rated 5 out of 5 by from BAMF This is absolutely the largest sink I have ever seen. The small front apron works perfect for us! The larger would have mad for tiny little doors below! I advise downloading the spec sheet from Kohler it is not included in the shipment. I had to shim the sink 2/16ths because the instructions do not match. they are some generic BS. Perfect for bathing animals and my 7 yr old. Just a size reference for you!

Rated 5 out of 5 by from Beautiful Sink Probably the best in cast iron; get one now before the greenies shut down heavy industry. We settled on the 36" because NO colors are available in the 34". It's big, it's beautiful (comes in many colors), so if you want a farmhouse sink, this is it. Also, excellent service from Build.com (on phone) and fast delivery from Estes.
