High Quality Double Sink
[This review was collected as part of a promotion.] Washing dishes is so much more enjoyable having this new double sink! It was a pretty simple installation. The parts for the sink were packaged and organized nicely, which made the installation process smooth and easy. I really love the design of the sink. I can tell that the quartz is made of high-quality material because it's heavy duty and has a beautiful, natural white color. What I especially like is how the quartz material seems to keep my sudsy water hot for a longer amount of time, compared to my previous stainless steel sink. The sinks reduce sound during cleaning, have a smooth surface, and are easy to clean as well. The sinks have so much depth, and it makes it easy to wash dishes without having to deal with a cluttered space. In addition, the stainless steel drains with a removable strainer are absolutely beneficial. The drains smell fresher, and they stay unclogged. Overall, I'm very satisfied with my new, wonderful double sink!

Loving my sink & faucet
I love my kitchen sink and faucet from Kraus. Its a great sink at a great price. The sink can be undermounted or dropped in. It fit my 33" cabinet with about a quarter inch left on each side undermounted, my countertop guys were able to install it with no issue.

Loving my new sink
Have had my beautiful new Krause Black Granite sink installed now for two week and love it! While, yes, it takes a little more attention to keeping it clean and dry after use, it hasn't made me regret my purchase. The sink is big and deep. Exactly what I need to handle our Sunday family dinner weekly. Only one negative so far. After the first week, I noticed a smell. Wiped it down with a disinfecting wipe and smell gone and hasn't returned since. Thank you for a beautiful product! P.S. love the towel you supplied. Comes in handy for those quick wipe downs.
