Questions & Answers

I’m replacing an older Kohler drop in sink (approx.) counter opening of 18” x 15.5” (oval) outer edge of sink is 19.25” x 16”. Does Kohler have a sink that I can drop in to replace the existing ones (2 of them)?

Hello Dave, this is Paige with Kohler Customer Service. I am happy to help. A cutout template would need to be obtained to determine if a sink will fit in the existing cutout. You may contact our literature team at 1-920-803-3985 with the model number of the sink you are interested in. Thank you for choosing Kohler.

                  Rust Problem
                  I bought this in 2016 and have the same rust issues around the drain and overflow hole. I made the mistake of replacing the previous sink with the same rust problems. The lifetime warranty does not cover rust because it is environmental (per Kohler) or can only be a problem of the installation (per Kohler) and apparently not of manufacture. I do not know why the inside wall of the sink behind the overflow hole would rust if no water is flowing there and if it was coated properly. I also complied with the installation instructions.

                  Hello Rusty, my name is Meli with Kohler Co. Thank you for taking the time to share your experience. I understand how frustrating it can be to see rust developing around the drain or overflow area, and we appreciate the opportunity to provide some clarification. Rust around the overflow opening is typically caused by environmental factors, not by the enamel or vitreous china material rusting itself as vitreous china does not rust. Small amounts of water can enter the overflow channel during normal use. If the water does not evaporate completely—often due to humidity, limited ventilation, or water sitting for extended periods—it can cause corrosion. Hard water can also leave mineral deposits that trap moisture against the surfaces, accelerating discoloration or corrosion over time. While we understand your concern about proper installation, these factors can develop even when installation has been completed correctly and all manufacturer guidelines are followed. This is why rust or corrosion is classified as an environmental condition rather than a manufacturing defect, and therefore not covered under the product warranty. If we can provide further clarification, please email our customer care team at KohlerCustServ@Kohler.com. We are here to help. Sincerely, Meli A., Kohler Customer Service
                    Fast delivery, good packaging and good quality. Used the (solid) box it came in to hold the sink while I installed the faucet and pop up drain. The overflow hole has a plastic “trim” that can be replaced and I might “upgrade” it later.

                    Leaks
                    After installing the sink I filled it with water to check for leaks. After the sink was full I let the water go into the overflow for several minutes and water started dripping under the sink. I looked under the sink and there was a small hole in the overflow channel. I'm going to buy some J-B Weld and try to seal the hole. If that doesn't work I will return it. I'm very disappointed in Kohler's quality.

                      Our ten year old Kohler sink developed a crack near the faucets. We bought a replacement and when the old sink was taken out it was found out that there wasn't proper glue or whatever holds it to the counter. When removed we were told that we needed a new counter to put the new sink in. The new counter comes later this week.

                      Rusted sink
                      Bought 2 of these for our master bath in 2019, now one is rusted from the overflow and the drain, the other one is fine, so it’s not us or the water we have. First time I’ve ever been SO unhappy with a Kohler product.

                      Hi Alex29, this is Sarah with Kohler Co. I'm sorry to hear one of your Farmington bathroom sinks is rusting in two places. Rust around the drain and overflow ferule can occur when water gets under the surface. This is likely caused by the silicone (or lack there of) breaking down and needing to be resealed. We suggest removing the drain and overflow, cleaning the affected area to remove the rust and resealing these items using 100% silicone sealant. Please call us at 1-800-4KOHLER (M-F; 8am-5pm CST) with any questions or for additional assistance. Sincerely, Sarah S. Kohler Customer Service

                        I installed this sink in about 2006 and it was beautiful...for barely 2 years. It quickly started to rust around the overflow hole and just deteriorated from there. I was annoyed at the time (I thought Kohler was a good brand!) but just let it go. 10 years later the enamel is flaking off so badly I got a splinter of enamel in my hand just trying to clean it. Good thing I have a recent tetanus shot! I only happened upon these reviews because I'm now searching for a replacement sink and I'm seeing that other people have had the same problem with this sink in the past. Hopefully Kohler has addressed the problems in the recent model. But I'm going with porcelain this time. And probably not Kohler.

                        Hi Lori, my name is Sarah with Kohler Co. I'm sorry to hear your Farmington bathroom sink is not holding up around the overflow. The overflow is sealed with 100% silicone sealant to prevent damage to the enamel. The overflow cover can be removed, replaced, and sealed with fresh sealant. We do not recommend using anything other than 100% silicone sealant. Please email our team at KohlerCustServ@kohler.com so that we can discuss this with you further. We look forward to hearing from you! -Sarah B. KOHLER Customer Service

                          Product arrived on time but has defects. Enamel near back left side of sink is noticeable pitted. Kohler emblem is installed crooked and the drain hole for the overflow is not centered in the sink. I am disappointed in the quality of the product. I expected more based on the brand name and cost of the product.

                          My three-star review of this product gives Kohler the benefit of the doubt because I've bought and installed many Kohler enabled sinks, and they've worked out fine. However, I agree with another reviewer that downrated the product because of enamel problems. My sink is at least 15 years old; the other reviewer's a one star review, was written in 2013. Hopefully, Kohler has solved problem by now. They have changed the model number. I'm replacing the K-2904-8 sink with identical (?) K-2905-8 because pin holes in the porcelain around the overflow have turned into ugly rust spots. The enamel around the edges has peeled back as rust has worked it way up from the base. I'm buying basically the same sink so I don't have to replace the tile counter. If not for rust on older Kohler, sink would probably get four to five starts.
