The Riverby white enamel sink is beautiful.  Any debris in the sink washes into the drain right away, because the surface is smooth and the slope is perfect.  Also, the rim of the sink is angled so that when rinsing the sink, the water runs into the sink rather than the counters or the floor.

Perfect sink.

Beautiful bright-white sink, great size and depth. It arrived without any damage to the enamel. One of the only sinks I could find (in my size range) that had the drain offset from the center, which makes more room to set large pots and pans on the bottom without covering the drain.

Beautiful sink, no damage

Well after 7, yes 7 Riverby cast iron double bowl sinks, we have one with plumbing attached! Shipping refusals, cracks in the enamel or even a warped sink were the causes for this to be a time consuming task. At a $1000 a sink someone is not doing there quality checks or shipping correctly. Buyer beware. Our sink does look good but the experience was just not up to par.

We ordered this sink directly from Kohler.  We received it in a timely manner.  When it was installed, we found two flaws in the finish.  One is a pit on the front the other is a void on the base.  Pictures are attached.

We love the design of the sink!

I had my kitchen remodeled and the sink looks absolutely lovely.  I also got a faucet from Kohler in black matte and the contrast is great.

Love my purchase

Beautiful sink. It comes with an inside wire rack. It covers about 2/3rds of the sink leaving the drain area free. Excellent design, keeps your pots from scratching the porcelain yet allows rinsing plates etc.  the sink is slanted on bottom so everything drains easily into the drain. 
I love a single sink, allows for large items to be submerged. Split sinks make no sense for me.

Functional Design with beauty.

With very light use for 2.5 months (3 people in the house, very little cooking) the sink has developed tiny black marks that are not removable with the Kohler cast iron cleaner.  It is a beautiful product but the marks are becoming more noticeable as the number of them increases. I regret choosing this product and am dreading Thanksgiving when I have other people using my sink expecting it to be a normal sink - I am embarrassed to have to micromanage the use of my kitchen sink.  It is by far the biggest regret of my home remodel which was done exclusively with Kohler products for 2 bathrooms and a kitchen.

SO disappointed - marks will not come off

Just like the previous reviewer we also found that this sink not only easily stains but also difficult to clean even with Kohler’s own recommended product. Given the higher cost of this item, we expected a higher quality product commensurate with the price tag. The staining occurred from the very first weeks of having the sink and over the last 1.5 years since its installation it has only gotten progressively worse. Yellow stains from the matching sink rack’s rubber feet continually leave yellow stains on the sink (see photo). In addition to staining, easily scuffs (see photos). We are a house hold of two adults who do not do heavy cooking. I can only imagine what this sink will look like with a family with children.  I hope this is simply an issue with their particular product and not Kohler cast iron sinks generally. This is our first Kohler product, and, given the quality of this product, may very well be our last. (Same goes from Signature Hardware and their peeling black hardware).

Easily stains and scuffs, not easy to clean

I purchased this sink with one hole. The first I received was a mislabeled sink. It was an undermount sink in a drop in box. Called and was sent a new one. This was the correct sink but arrived with a ton of the enamel broken off. Called again and was sent another one. At this point we were a month into this ordeal. The sink arrived, looked great. It was installed and looked good. I hand washed some dishes and noticed the divider enamel had chipped off. There's a line where it looks like it was not enameled correctly. I was not washing anything heavy and I didn't hit anything on the sink. I ended up just getting my money back and now have a messed up sink installed.

Awful Craftsmanship

Elevate compact kitchens with the KOHLER Riverby 25" top-mount single-bowl kitchen sink, an elegant and versatile addition that works beautifully as a primary, secondary, bar, or utility sink. Its generous single-bowl offers ample room to soak and wash large items, while beveled front and back edges help keep water contained. The gently sloped bottom toward a single offset drain minimizes pooling and opens up more workspace above and storage below. Crafted from enameled cast iron, this sink resists chipping, cracking, and burning, so its aesthetic appeal endures through years of daily use. The included custom-fit bottom sink rack adds another layer of protection, shielding the surface from everyday wear and helps preserve that just-installed beauty. Designed to fit spaces starting at a 27" base cabinet, and offering three faucet holes plus an accessory hole to the right, the Riverby single-bowl sink brings thoughtful function and refined style to kitchens of every size.

Elegant and versatile, the K-5872-4A1 cast iron sink is sized to fit small spaces as a primary, secondary, bar, or utility sink. Includes bottom sink rack.
