Great sink

Overall, I am quite happy with the sink. It came packaged very well with no damage. Extra bonus, the high density Styrofoam it was packed in can be used for kneeling pads. The accessories are a nice addition. I did not think I'd care for the in sink protective grate, but I do. I thought I would like the cutting board but maybe not so much on that one as it needs continual cleaning and is heavy. I am also mystified by the drain basket with attached flange. If water pressure is high or even medium high, water collects in the sink as it does not drain quickly. I ended up putting the flange over a strainer I had previously. I owned a quartz sink previously and had to have again in my new home.

A great new visual update to our kitchen

All our kitchen appliances and appointments were in black except for the stainless steel sink so the new black bowl sink completed the color scheme. We find the single bowl more convenient for all kitchen sink functions. Installation was quick and easy, including attachment of the garbage disposal.

Just Beautiful

I have a similar sink in my laundry area but my kitchen sink was an cast metal black color that someone had ruined. It was a inside mount. The only way to to replace it was to go with an outside Mount and this Karran sink in Matt Black was just perfect. It has a very subtle shimmer.! I love everything about it.. It's very easy to take care of and it doesn't ask much for me. I highly recommend I've waited 10 years for this and yesterday was the install. I am very very happy..
