About This Product

The Whitehaven apron-front kitchen sink features a streamlined and versatile farmhouse style. The Self-Trimming design requires only a simple rough cut, overlapping the cabinet face for beautiful results. The tall integral apron also acts as a drip edge to protect the cabinet from water damage. A large single basin accommodates large pots and pans, while the sloped bottom helps with draining and cleanup. Crafted from enameled cast iron, this sink resists chipping, cracking, or burning for years of beauty and reliable performance.

        Hi amidroc, my name is Meli with Kohler Co. I am happy to assist with your question. The Whitehaven sink K-RH6489 requires a 36" base cabinet. Thank you for choosing Kohler.

          This should be the recommended size for the IKEA 36 inch sink cabinet. It just arrived and the dimensions are spot on to fit inside. Supports are needed.

              Since this model has no holes for faucet, etc, where would the holes have to be placed?

              The holes for faucet, etc. are drilled into your countertop material behind the sink.

                Hi Jean, my name is Meli with Kohler Co. I am happy to assist with your question. The holes for your faucet would be in your counter in this case. Thank you for choosing Kohler.

                      Terrible product
                      I ordered this sink and, unfortunately, it arrived damaged. I contacted customer service immediately to find out what my options were. I was advised that I could return the damaged sink to my local store for a full refund. I explained that I still wanted the sink and asked if a replacement could be expedited, either overnight or within three days, because I am in the middle of a kitchen renovation. I was told this could not be done because the company only uses one shipping service. I then asked to speak with a manager to see if there were any other options available. The manager advised that expedited shipping was not possible and stated that the sink would "probably get damaged again." I am extremely disappointed with this response and the overall customer service experience. The original sink arriving damaged was already an inconvenience, but I do not understand why there is no way to expedite a replacement, especially when the damage occurred during the original shipment. My countertops are ready to be templated, and because I now have to wait for another sink to arrive, I have to postpone the countertop template and potentially delay the entire project. I understand that shipping damage can happen, but I expected better assistance in resolving an issue that was outside of my control. I would appreciate the company making an effort to expedite a replacement sink or provide another reasonable solution so that my project is not delayed any further.

                        Terrible sink a quality. Kohler customer care replaced our first one within a year and we already need a new one. It costs us $1400 to move our kitchen island and Kohler doesn’t cover anything, just the terrible sink. We will never buy from them agai.

                          Stains easily and cannot remove stains
                          Had this sink for about four years. After about a year it was so stained that it looks horrible. Stains cannot be removed. I used only the Kohler liquid cleaner they recommend but it didn’t remove stains. After three years I gave up and tried every cleaner out there and even abrasive cleansers, Magic Erasers, scouring pads, etc will not remove stains. It also scratches very easily. Over $1000 for this junk. I do not recommend.

                            Scratches with ease.
                            Just my wife and I in our newly remodeled retirement kitchen and we are extremely disappointed with this farmhouse sink. Scratches started appearing almost immediately upon use. We were always careful not to drop dishes on the sink or “throw” silverware because we wanted to keep our brand new kitchen looking pristine. Even with our careful behaviors we almost immediately started noticing scratches in the enamel and wear marks from normal every day use. We put this under mount sink under concrete counter tops so there’s not an option to remove and replace with another sink brand. We thought we were buying quality with the Kohler brand but Kohler has let us down on this sink.

                            Hello MikeK, my name is Meli with Kohler Co. I am sorry to read your Whitehaven sink has developed scratches, this seems unusual as the sink is manufactured of a durable Enameled Cast Iron material. The scratches you are experiencing may reside in the top enameled surface of the cast iron and can be easily removed with the Kohler Cast Iron Cleaner K-23725-NA. Additionally, the use of a basin rack will prevent any direct contact with the basin of the sink; the recommended sink rack for you Whitehaven is K-6449-ST. If we can assist with your sink further, please email our customer care team at KohlerCustServ@Kohler.com. We are here to help. Sincerely, Meli A., Kohler Customer Service

                              orange peel texture
                              I read many reviews that mentioned a lumpy, orange-peel like texture and thought to myself “they’re probably just unlucky and received defects.” Nope. I think the demand is too high and it looks like kohler is pumping these things out without waiting for the coating to completely dry. I tried to take a look before leaving the store but its packaged so tightly and its so heavy that I couldnt check it by myself. I read from other reviews that this is the look, theyre never smooth. FALSE. My friend has a kohler farm sink and hers has very minimal texture, yes some texture but not lumpy like mine. Also, this high priced item doesnt get trackable shipping so if youre on a strict timeline like I was dont depend on it arriving on time or being able to track it.

                              Hi jenv, this is Sarah with Kohler Co. I'm sorry to hear you are not happy with the finish on your Whitehaven apron front sink. Due to the nature of enameled cast iron, there is a measure of rippling or waviness to vertical walls as gravity pulls the enamel down during melting in the furnace. Horizontal surfaces melt smooth. We'd like to connect with you directly to best assist you. Please email a photo to us at KohlerCustServ@kohler.com. Sincerely, Sarah S., Kohler Customer Service
