Review: Arrived intact. No install issues or cracking. Brown is beautiful - I bought the brown color. It is rich dark brown but can definitely tell it’s not black. No issues with install. It’s heavy amd very sturdy. The depth is perfect for deep pots or setting a glass in the sink and not seeing it but not so deep I’m reaching or bending over where it would hurt my back. It looks luxurious. The bottom is sloped enough so can still set items in it without them tilting or being unstable or sliding but some water will still stay around the edges, I’d rather they than an uneven surface. When scrubbing pots, you want it less sloped or it rocks. Fortunately, it’s not showing water spots or scratches. I bought the signature brass flange to match my hardware and it fit perfectly and gave it an upscale look.
Review: Exactly as described - Perfect piece to finish our kitchen. It’s exactly as described.

Perfect piece to finish our kitchen. It’s exactly as described.

### ⭐⭐⭐⭐⭐ Very good quality
*by M***. on December 19, 2023*

This is our second quartz kitchen sink. The first one was a competitors that was good quality. What attracted us to the Karran brand where's the warranty and the good reviews on Home Depot site. When I received the sink it was packaged extremely well. There is so much high density foam that you would have had to drop this off a roof to have damaged it. The quality of the materials was excellent. A white sink can have problems with consistent color and this one did not. We are very happy with the sink and we're even able to buy a white flange that covers the garbage disposal stainless steel one period it looks really good.
