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.

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.
