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-6489 Reviews

Rated 5 out of 5 by from Good product, luxurious looking We are very happy with this purchase.. although my builder complained about the edges not being perfectly level and square but I think its because it is cast iron. This is a heavy sink so we had to add extra support under it so it wouldn't crush the cabinet.

Rated 5 out of 5 by from Beautiful Sink Perfect sink for what we wanted. Really nice looking and built to last a lifetime. My 40 year old Kohler tub (same construction) still looks like new. I was concerned about fitting a disposal but a full size 3/4 HP InSinkerator fit with room to spare. Very easy to install using instructions provided.

Rated 5 out of 5 by from Nice Sink is huge. We ordered the sea salt after seeing a tiny sample at a show room under LED lights but it doesn't bling like Great Gatsby as we had hoped but it does makes the sink look older than the modern white appliances though. To install was easy We tacked 2x4 ledgers (yellow pine because I didn't want the metal is cast iron to possibly conflict with the copper in PT) with 2 trim nails close to where it measured where it should be each side set sink then stuck a block between the sink and cabinet and tapped the ledger down until level with cabinet and ran a 4' level across removed sink and screwed before the glue in the ledgers dried. (We also had under supports that were too low by cabinet man so I didn't worry about tapping the ledger down and falling down but I'd put a block and stack some wood up close incase if I didn't) Pick a big facet with this beast we have a bridge facet that swivels and sticks out a good bit and a good sprayer. Wish I'd have got the soap dispenser as I thought it wouldn't look old but a bottle of soap probably looks worse...couldn't imagine having a normal facet or no sprayer.

Rated 5 out of 5 by from Gorgeous The sink has only been installed for a few days now, but I am in love! It is such a statement in the kitchen!! As noted in the description, the sink is not completely square and level. Ours was off by about 1/8-1/4" adding extra time to installation. Buy this sink, you won't be disappointed!!

Rated 5 out of 5 by from Kohler K-6489 (Fixture): Kitchen Sink Cast Iron Beautiful kitchen sink. Hasn't yet been installed but have been admiring it in the box. The biscuit color is fantastic!

Rated 4 out of 5 by from Nice sink, as it should be for the premium price! Have had the sink for about eight months, only one minor complaint: Had a heck of at time getting it leveled properly, spent hours shimming and re-shimming. Finally talked to the countertop folks who told me "you can't ever get those sinks level because the sinks are always warped". Had I known this, I wouldn't have spent all the time taking the sink in and out (and it's very heavy!) trying to get it perfect. In spite of this (one corner is about 2mm higher than the rest), the sink looks fine, and drains properly.

Rated 5 out of 5 by from Great Value This is a hard to find product that is easy to install and provides the traditional look of a apron sink at an outstanding value.
