Product Description

36" minimum base cabinet width. Kohler cast iron. Acid-resistant enamel finish. Double (equal) compartment. 33" x 22" x 9-5/8".


Bring refined style to your kitchen with the beautifully stylized curves and subtle, rounded rim of the Kohler K-6626-6U Langlade undercounter kitchen sink for five-hole installations. Kohler's innovative Smart Divide barrier makes it easy to wash and rinse large items while still keeping the two basins separate. And with the faucet escutcheon centered over the divider, you'll be able to reach into both basins without requiring the use of a pullout sprayhead or sidespray.

K-6626-6U Langlade Double-Basin Cast Iron Kitchen Sink with Smart Divide At a Glance:

  • White finish

  • Limited lifetime warranty
At a Glance

Crafted from enameled cast iron, this sink resists scratching, burning, and staining for years of beauty and reliable performance. One of only a few plumbing manufacturer who produce cast iron products in the United States, Kohler protects the Langlade with a limited lifetime warranty. And the enameled cast iron has a smooth, non-porous surface, which makes it very easy to clean. It has a basin depth of 9 inches, and it measures 33 x 22 inches (LxW) overall.

This version of the Langlade comes in an undercounter design with an oversized six-hole installation design. It's also available in the following self-rimming variations: single-hole, two-hole, three-hole (for three-hole faucet), three-hole (for one-hole faucets plus accessories), four-hole, and five-hole designs.

Easy Handling with Smart Divide

Kohler's Smart Divide kitchen sinks feature dividers that are half the height of those found in conventional double-basin sinks, giving you the best of both worlds--the openness of a single basin combined with the divided functionality of a double basin. You'll be able to completely soak cookie sheets and other large pots and pans that typical double-basin sinks could not accommodate without losing the ability to multitask projects like washing and rinsing dishes. And you can easily transfer large pots and pans across sink basins without making a mess--and keeping the water where it belongs.

With typical double-basin sink dividers, the clearance between the faucet and dividers is minimal, and placing larger pots and pans between the two can result in damage to both the faucet and the sink's finish. But with Smart Divide being just half the height, you'll get optimal clearance.

Enameled Cast Iron: Lasting Strength and Style

Built to last for generations, Kohler's enameled cast iron sinks make an enduring statement of beauty in your home. With 20 gorgeous hues to choose from, you'll find a Langlade sink that fits your personality and home decor. Its rich finish and long-lasting presence make a bold statement in any room--standing beautifully on its own or highlighting other materials.

Colors include white, almond, sunlight, dune, Mexican sand, thunder grey, biscuit, ice grey, sandbar, cashmere, iron cobalt, black black, caviar, cane sugar, sea salt, basalt, black 'n tan, frost, ember and suede.

Produced in Kohler, Wisconsin and crafted from a minimum of 80 percent recycled material, they're built with lasting beauty and the strength to withstand the test of time. Kohler's manufacturing process ensures that each piece is a genuine, handcrafted fingerprint that carries our pride into the home for generations to come.

Kohler's Cast Iron Limited Lifetime Warranty

Kohler warrants the enameled cast iron component of this kitchen sink to be free of defects in material and workmanship during normal residential use and that it will not chip, crack or burn for as long as the original consumer purchaser owns his or her home. Gloss reduction, scratching, staining and alkaline etching of the finish over time due to use, cleaning practices or water or atmospheric conditions, are not manufacturing defects but are indicative of normal wear and tear.

I was in love with this sink, still am, but I've had to return it and have bought a Fireclay made by Rohl instead. Amazon had the fastest delivery of this Kohler sink, price about the same as other retailers, so I went with Amazon. It arrived via a shipping company 10 days later. The sink wasn't adequately cushioned on the corners - just some corner cardboard wedges that would not hold up to receiving a jolt. I noticed right away a chip out of one corner when I inspected the delivery. Called up Amazon, and they offered to rebate $105, or else take it back entirely. As my contractor was ready to install, and the crack would be hidden under the counter (undermount), I accepted the rebate. Everything dandy.

But then, as we got the sink in place and in strong light, we saw another hairline facture extending from the other corner into the bowl. No way that would be hidden, and it would only grow with time, attract stains, etc. So no choice. Called up Amazon, and they said they would have the delivery company call me to arrange a pickup, even though we'd already thrown out the original box, for full refund. That is incredibly good service, I must say.

So in the end, I went with a sink made out of fireclay, a clay base with glaze finish fired at a very high temperature. That's an entirely different material than the Kohler, which is a cast iron sink coated in enamel. Fireclay is about 20% more expensive ($600 vs. $500 in this case), but is reportedly better in all ways, less staining, more durable against scratches and chipping. I was told (not verified independently yet) that the old cast iron/enamel sinks were super durable, because they were made with lead. Lead was the bonding agent that made the enamel very tough.

I ordered this sink through Amazon back when I was doing extensive remodeling on a house I had recently bought. I've had and used the sink for almost a year, and it's easily one of the best remodeling ideas that I had. It looks SO much better with the granite countertop than other stainless steel sinks I considered. It also cleans up easy and takes a beating while still looking like new. I also like the way the Smart Divide feature makes it easier to clean big pots and pans.

We just had our Kitchen counters replaced with Salina White granite and decided on the Kohler Langlade Smart Divide sink paired with a Moen faucet. The sink is beautiful and the design if very well thought out. We can now wash pots and pans in the sink by laying them flat since the handle can lay in the other bay. This sink is cast iron so it is very heavy. You will need help to install it if you are doing it yourself. I had my granite installer mount the sink and then I did the plumbing and faucet. We only used three of the five holes, one for the faucet, one for the dishwasher air gap, and one for the soap dispenser that came with our faucet. You can always have more holes drilled if needed. The white coating can show marks really easy as other reviewers have mentioned but so far I have been able to remove every mark and stain using Kohler's cast iron sink cleaner, product number K-P-1888-NA. I highly recommend the cleaner because you will need it for sure. Dishes will sometimes put a mark on the sink and foods like spaghetti will leave stains sometimes. I read one reviewer used comet but for $6.68 and free shipping I don't mind buying Kohler's product since this sink cost over $500 and I want to treat it right.

One thing I was worried about when shopping for a sink was whether or not it would fit in our cabinet. We have the standard 36 inch cabinets that most new homes have nowadays. Since so many reviewers had differing thoughts on the maximum size that will fit a standard cabinet I decided to just go to Kohler's website. You can narrow your search down by cabinet size on their website. My granite installer also told me that he only needed an inch or two on each side because the under-mount hardware does not require much space on the sides of the sink.

I hope my reviews helps anyone looking at this sink. We really love the sink and would definitely purchase it again.

The sink was beautiful. The counter installers cracked it when they installed the new Quartz top. They, Cutting Edge Granite, would not take responsibility for it, but Kohler, whose fault it wasn't, were nice enough to send a free replacement.
I always buy Kohler now.

I know it's just a kitchen sink but I love it. It's so pretty, and deep, and its great for washing up the large items that don't fit in the dishwasher, which is mostly what I need to wash. No more water splashing over on to the floor or my clothes when I'm trying to rinse a cookie sheet! It cleans up fast and the surface looks great all the time. Couldn't be happier with it!

Color: Mexican Sand
After 15 years in our home, we finally decided to do a complete kitchen remodel. Next to deciding on which cabinets/colors to go with, probably the next most difficult decision was deciding what sink to get to replace our aging, mineral-stained stainless steel sink! After much research on the internet reading reviews and looking at pictures, we decided on this Kohler Langlade with smart divide.

Best decision ever! We got this sink in Mexican Sand and I have to say, it is beautiful! The Mexican Sand goes great with the dark brown/tan quartz counter top we got! It is super deep compared to the sink we replace and the "smart divide" feature is a lot more useful than I thought it would be. As a result of the sink being so deep I had to do some plumbing modifications in order to install it, but it was worth it!

Honestly, I feel like this sink is the crown jewel of our new kitchen!
