Gorgeous Sink!!!!
Color: White
I’m thrilled with this sink! It’s *GORGEOUS* and exactly what I was hoping for. It cleans up like a dream (soap and water and magic eraser are my go-to’s). It’s shiny and catches the light and looks like a CLEAN sink. Very satisfying 😂. I’ve had it for almost three months now, and I have no complaints. My number one recommendation is to use the metal grate they provide with the sink. We placed a cast iron pan in the sink without the grate and it made some scuffs I cannot remove. I can live with it though, so now you know. With the grate in place I don’t have to have anxiety over every time someone puts a dish in the sink! The off set drain is very smart. I couldn’t be happier with this decision. ... show more

Just use Barkeeper's Friend for stains. *INCREDIBLE* sink!!
Color: White
Yes, this sink stains and scuffs. But my god, if that bothers you, ignore the cast iron sinks all together--including their durability and incredible appearance. Fun fact: a brushing of Barkeeper's Friend and a scrubbing pad will buff the stains right out. Sink looks like new every time; I just add one extra step at night after I finish dishes. See before / after pictures above. That took me about four seconds to transition between them. Now, on to my actual review. These sinks are long-lasting and *gorgeous*. We had one in my old house for 15 years, and it looks fantastic the entire time. When it came time to renovate my kitchen in my new house, I knew exactly what I wanted--a deep, single-bowl sink with the drain on the right. This fit my bill perfectly, and was priced insanely fair based on its competition. I fell hard, and slammed the buy button! It came with a surprising amount of additions! The rack to protect the base is... basically useless, since it doesn't span the length of the sink. But the attachment strainer is amazing for vegetables and pasta, and my personal favorite is the rack pictured above to hold my scrubbers! The entire sink looks clean and amazing, and the size is *huge*. Can't be beat!! My mother has the Kohler farmhouse sink, and she's annoyed that mine is bigger. LOL. If you're looking for a great undermount sink that will wow literally everyone, look no further. A bit of elbow grease wasn't enough to turn me off this sink, and I doubt it'd be enough to turn off any of you. Just get some Barkeeper's Friend and use a few times a week, and you'll have a sink that will last and look fantastic. HIGHLY recommend for anyone with standard, builder-grade cabinets! ... show more

Measure! Measure! Measure!
Color: White
I really wanted an apron front but didn’t want to spent the money to buy new cabinets. I bought this for $750 and knew I couldn’t return it because it would be so costly due to the weight of the sink plus there would be a restocking fee. When we called the granite company they sent out a guy to look at it and said it should be easy enough to replace my SS double kitchen sink with this single bowl Castiron porcelain sink. He quoted me $275 to do the job. When they came out to do the job the sink wouldn’t work as easily as they thought because of the 5 holes along the back. They didn’t line up with my faucet and the price went up $$$$!!! We ended up buying a whole new granite countertop to fit this sink!!!! ... show more

Nice sink but received first one damaged and second one defective
Color: White
I received one sink from another vendor that was cracked. I ordered the same sink through Amazon and it arrived quickly, but the white coating is not smooth. The whole sink has a slightly bumpy texture. I kept it anyway because my whole remodel job was delayed and the surface was not cracked, it is watertight. Thought no one would notice but me, but already has been pointed out to me a couple times. Anyway my choice, but disappointed that quality control did not catch this because I was in no position to return a second sink and wait for a third. ... show more

The best sink design ever!!
Color: White
Simply the best sink design ever! It is an under mount, which is useful when you need to just wipe the counter into the sink. The under mounted area is easily cleanable, unlike many other under mounted brands.I love having the drain on one side for several reasons: rinsing dishes into the drain/garbage disposal keeps the rest of the sink generally cleaner, the plastic drainer with the little cutting board and the metal drainer that fits on the top edge of the sink are so useful, and the slight incline of the side opposite the drain keeps the sink drier with no standing water. Great quality. You get what you pay for. Should have gotten this years ago! ... show more

Favorite. Sink. Ever.
Color: Biscuit
This is a beautiful undermount sink! Being able to put large pans in the sink to wash is awesome! In my last house I had a smart divide (lower divider between sinks) but I still found it to be awkward when washing large items. The biscuit color is perfect with my off-white cabinets. I use the wire rack in the bottom of the sink. If wash one or two items they can dry on that rack without cluttering the counter until put away. I haven't used the other accessories. I've always had cast iron sinks. I considered the Silgranite to keep cost down. I decided to save money elsewhere and I'm so glad I did. Nothing beats cast iron. ... show more
