Kohler white is not "true white"
Home Depot website did not allow me to write a 2nd review or provide a response to Kohler's customer service. So I'm writing another review as a "brand new" review. As mentioned in my previous review, I like everything about this sink except the color, which is not "true" white. It has a shade (hue) of blue or green, which gives it the "off white" look. I went to three different Kohler "official" stores in the area, and even visited warehouse in one of those. I requested them to open the box for me so that I could check the color. They were cooperative and opened a few boxes for me - and they had the same "off white" color! They were able to compare the color with some other Kohler sinks and they also agreed that color on Riverby model was not "true" white. I bought a yet another cast iron sink from a different brand Ceco (model number 748-UM) and I'm posting a pic for side-by-side comparison of color. The one with five holes is Kohler, and the other one is Ceco. Functionality wise, this sink is exactly same as Kohler Riverby (except the five holes, which I don't really need anyways). But it is so very obvious that Ceco's white is so much "whiter" when compared to Kohler. This is the color I was looking for! I will be returning Kohler and I'm surprised why Ceco isn't getting good publicity. Their sink (material/quality/design wise) looks very similar to Kohler and a lot more people should buy those - especially if you were looking for a "true white" color.

This sink was perfect for my newly remodeled Farmhouse kitchen, December2020. I didn't realize that a deep sink would make such a big difference to my kitchen tasks. It is beautiful, large, shiny, and practical. I love the accessories as well. So completely worth the high price tag.

An exceptionally nice sink for most mid-sized kitchens
My wife and I run a small property investment business in Western Pennsylvania. We buy, rent, renovate, and sell homes. I am a registered PA home improvement contractor and head up our small rehab team. We handle most of our renovation work in-house, especially the most common projects we do, like kitchen renovations. We have extensive experience putting durable kitchens into our city rentals and luxury kitchens into the homes we renovate to sell. Therefore, I’m going to talk about this Kohler Riverby sink from a consumer buying standpoint and a bit from the professional installation standpoint, because there’s quite a bit to say about both. In the last twenty years or so, Kohler has worked hard to promote itself as a general kitchen and bath fixture designer and I’ve run across a number of people who don’t know much about the company outside the ads they’ve seen on TV. The ads tend to highlight Kohler’s commitment to original designs, and their tagline is “The Bold Look of Kohler.” Well, it’s true that the company has updated many of its product designs, but if you’re here, looking at something as classic as an enameled cast iron kitchen sink, it should also be said that Kohler has been making them in Wisconsin since the 1880s. Quite simply put, there is no major manufacturing company worldwide with a prouder or longer legacy of making these fixtures. Generation after generation of American builders has consistently chosen Kohler when they need enameled cast iron fixtures. This is one of the no-brainer realities in American residential construction and luxury home improvement. No other domestic company comes close, no foreign company can reasonably compete with Kohler. Most especially when it comes to high-end enameled cast-iron kitchen sinks, Kohler has practically cornered the US market for more than a century, through good times and bad. This is an undermount sink, meaning that it is attached to the bottom of a solid state polymer, stone, or engineered stone countertop. I have personally never seen a cast-iron undermount sink under any sort of plastic countertop. The usual pairing is with 3-centimeter-thick granite. The way that undermount stainless steel sinks are usually mounted to the bottom of a countertop is by epoxying them in, and then reinforcing the epoxy with mechanical clamps under the counter or in some cases a strap arrangement. You may be familiar with this. This is because a stainless sink of this size weighs from a third to as little as a fifth of a cast-iron sink like this one. Before epoxies and sealants were as advanced as they are nowadays, it was more common to carefully build a sturdy wooden frame under the level of the countertop, drop the undermount sink into it, and then install the (very heavy) countertop with a template-sized hole for the sink cut into it over the sink, sealing the gap between the sink and the bottom of the counter. That is still one way that this sink can be installed. Done properly, the installation will last practically forever as long as the wood frame is strong enough and heavy ceramic, metal, or stone objects are not thrown with vigor into the sink. The porcelain coating on these sinks is many times thicker than the wafer-thin coating on things like steel bathtubs. This sink will likely outlast the functional lifespans of most residential buildings erected today. So from a consumer standpoint, a sink such as this is among the most lasting investments you can make to increase the value of your home. For a long time, enameled cast iron kitchen sinks were considered too expensive compared to much of the cheaper furnishings you could buy for your kitchen. Slowly, as issues such as renewability and recyclability, green building materials and environmental toxicity, uncompromising microorganism resistance in the age of the superbug, as well as a certain nostalgia for the solidity of the past versus the flimsiness of the present become more and more important to many consumers, a new appreciation for the lasting value of these sinks has come about. Doubtlessly, this appreciation will also pass someday, and these sinks will once again fall out of favor among the buying public. People will call them dated and old-fashioned again, a relic of estate houses of the early twenty-first century. I still love these sinks, and this one is a beautiful, functional example of why. First up there’s the size. 33-inches is the most common sink size for medium-sized kitchen prep sinks. Unless you have a very large kitchen, with a main and a secondary food prep sink, or you invest in an apron or farmhouse sink that is specifically designed to look enormous in your kitchen, a 36-inch undermount sink will generally look oversized in it. Once the size is out of the way, there’s the design with the oversize holes for fixture installation. The fact that the rear flange extends to include these holes means that there’s a great deal more surface space for the sink to be sealed to the counter, and that becomes more and more important as time goes by in the lifetime of a row of bottom kitchen cabinets, which may more or shift over the decades. There’s less of a chance that the sink position will shift and compromise the installation. Figure A shows the precision finishing of the gently-rounded enamel in the corners of the counter. These days, many reinforced stainless steel sinks sold as “Euro-styled” and “handmade” are made with sharper corners. It is more difficult and expensive to precisely cut and finish the template hole for these sinks in a stone counter using conventional granite fabrication tools. As a fashion statement, the sharper corners on the stainless sinks I’m talking about look up-to-date and sleek. In terms of practicality, they also make the sinks more difficult to clean and install correctly. You should generally go with this gently rounded style from a consumer standpoint. The only exception to this is if you need, for some reason, more sink depth for soaking than the 9 5/8 inches provided in this sink. If you are going with a classic configuration, that means the sink will be mounted under 3 cm granite, which means that the true sink depth for this sink will be approximately 10 3/4 inches. Figure B shows the stainless-steel sink grate that lies on the bottom of the primary bowl. It is fitted with heavy white bumpers. Ideally, in a stainless steel sink, the sides of the grate should have their own bumpers. In a cast iron sink, this is unnecessary, as the porcelain coating is more scratch resistant than the stainless steel it rubs against. Figure C shows the 23-inch undermount kit provided with this sink. The Home Depot needs to advertise this better, as this steel undermount kit is an expensive add-on on the Kohler site. The undermount kit makes it much easier to install this sink and precisely adjust the placement of the sink on most undermount configurations (every straight run of counter except in a corner or on a curve -- you still have to use the wood-framing method for these.). Figure D will only be of real interest to the professional installer. The little cast iron feet on the bottom of this sink means that you can dry-fit it easily by standing it on a site-built wood platform. This will make it easier to use the undermount system to achieve the best possible fit on the template-cut hole. Figure E shows the template that comes with this sink, again, this will be of significant interest only to a professional countertop fabricator. The template shows the edge of the undermount sink, which many such templates by less careful manufacturers omit. This will make it easier to deal with any sort of custom installation or various polishing errors in finishing the sink hole. Overall, this is a very well-made cast-iron sink, and the Kohler legacy of more than a century of making these fixtures shows very clearly in the final product. Properly installed, this sink is going to outlast its current newfound popularity. It is an extremely expensive luxury home accessory that is both functional and beautiful. It is very difficult to damage this sink with reasonable use. I plan on putting this into the next mid-sized luxury kitchen we renovate for sale, and I am confident it will increase the value of the home and make the buyer very happy.

I just picked up this sink (model number: K-8679-5UA3-0) from store after ordering online and to my surprise, the color is not white. It looks a little creamy! Home depot guys tried to convince me really hard that this is white color and it's the lighting in the store, which is making it look like that. But it clearly looked like "not pure white". They suggested to at least take it home and see if it matches the light in my home. It's pretty heavy and I had to bring two other people just to carry it to my home. But as expected, the color still looks different from "white", not same as the picture on Home Depot's website. After doing some more research online and looking directly at kohler's website, I am guessing the color they gave me is actually "Dune" (model number: K-8679-5UA3-NY). But Home Depot is not willing to accept this and they insist that it is white, which it's not!! I don't think I'm going to keep this sink - it's expensive, and it would've looked nice in my kitchen, but Home Depot folks are selling a different color for this model. Buyer beware!

Hello, this is Sarah with Kohler Co. I'm sorry to hear your Riverby cast iron sink does not appear to be white, when this was the color you ordered. We suggest looking for a barcode label on the underside of the sink. It will have a serial number starting with the letter S. The serial number will tell us the color of the sink. Please email us with the serial number and a photo of the sink. Your delight is a top priority and we are happy to help. Sincerely, Sarah S. Kohler Customer Service
Love the depth of this sink
[This review was collected as part of a promotion.] We chose this sink for our new construction home and could not be happier with our choice. The sink is very deep - it helps eliminate splashing and allows for soaking large pots. The quality is excellent. Cleans up well.

Beautiful! We have only had this for 2 months. We had this professionally installed so I can't speak to the ease of installation, But, it is absolutely beautiful! It makes the kitchen gleam and is just so clean looking. It is well worth spending the extra money on. We opted for a positive reveal which pairs wonderfully with the sink. The bowls are on much deeper than what we had previous so that could be an issue for some people but others may love that. I placed the metal rack inside the right side which elevates the bottom bowl by an inch and helps my back from straining while I do dishes. This sink will not disappoint!!

We got lucky and found this sink in stock through Home Depot and received it in about a week. It came in in perfect condition. Koehler sinks are fantastic - this is our second cast iron we have purchased. The Riverby looks great installed under our quartz countertops. The accessory kit is an awesome bonus - the cutting board/catch basin is useful when cutting up fruits and veggies and the mini hanging strainer is a cool addition. Great sink!
