Rich looking solid sink

Really big sink easy to install no waterspots and looks more elegant than Stainless Steel. Only knock is there is no option for Kholer disposal with mathing the color. o I had to use the original Stainless steel. Would have been nice to have a matching one but still love the sink.

Great sink

I bought this sink primarily because it helped solve a design issue with my kitchen remodel - wanting to shift the sink to the right to center under a window. The offset design allowed that to happen with no in-wall plumbing changes. On top of that, I like its large size and it worked great with my quartz countertops. My only caution is not to let food scraps sit overnight as it can stain but cleans up easily with regular soap.

One Big Bowl - quartz

I love my new sink. The one large bowl makes it so easy to wash refrigerator shelves and large items. The gray color is perfect for my new countertops. I also am loving having the under mount as well, just brush those counter crumbs right into the sink.
