Quarza 31-inch Undermount Single Bowl Granite Kitchen Sink in Black Onyx, KGU-413B

Looks great! Feels like a good quality sink.

This is nice addition to the kitchen and big enough to put a cake pan in. Highly recommend.

I’m really happy with this sink- it has a matte/ low luster finish that I feel will hold up better to my cast iron pans and heavy pots over stainless steel options- it looks nice and has plenty of room for my large pots and pans. I purchased this product as "Used like new".

The product is good

Was wary of a black sink, but it looks great and cleans easy. It does scratch though, so get a guard for the bottom.

This sink is beautiful. It looks great in our kitchen. We purchased the black version and it contrasts nicely with our white quartz counters. However, I can not give it 5 stars since the first one had multiple hairline fractures down the corners of three of the side walls. When our fabricator came to install the counter and the sink for us he couldn’t finish installing the sink because he noticed the fractures. It was super disappointing since we planned to have a party the following weekend. However, amazon did a fantastic job sending the new sink before we had to return the broken one. It arrived in 3 days and we had 30 days to return the broken one (drop off at UPS, easy!). The replacement is beautiful and works really well. Although there is room for it, we decided to go without the garbage disposal and we are happy we did; the drain and strainer work really well and it’s easy enough to toss the bits into the trash. I love our new sink! Just really inspect it before you install it. Best of luck!

I fell in love with this sink as soon as I found it on Amazon. Read the reviews and felt confident that this was a great product with a perfect price point. Was on alert for cracks when delivered, but we lucked out-- arrived in perfect condition. It is gorgeous in person. So roomy. And it has a little sparkle in the right light, which I also love. The only flaw we could find was the mounting equipment. This is a heavy sink, and the brackets were not up to the job. Ended up bracing it from underneath with boards.

This sink is absolutely stunning in our new kitchen! We took a gamble as it seemed 50% of the reviews mentioned cracks upon receiving, so we were hesitant, but ours arrived unscathed! No cracks! And it seems like it will be very durable and scratch resistant, which is important to us as we only use cast iron to cook. We’re about a week in from install and have used it almost every night to wash heavy cast pans & a large griddle, with no issue! It should be of note that when our stone guy came to measure for our counters he mentioned, unprovoked, this brand was of the higher quality sinks he’s seen/installed. (Purchased the InSinkerator flange separate from amazon) Will update if any issues arise
