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.

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.
