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.

Such a practical sink. I love it, how could you go wrong.

I love that with hard water you don't see the rust creep in like my old sink did. I tried to stay on top of it but I wasn't having any luck. I love that I no longer have to figure out how to soak large pans, I can easily fit every size pan I have in that sink to soak of I need and still have room on the side to do other things I need to do. I love only having one drain to worry about as well, it all leads to the garbage disposal. The only down part I could see people having is if you have back problems and you use the center portion to prop your pans/dishes up to bring them closer to clean. This part did take me some getting used to.

Awesome upgrade!

Very nice sink! Upgraded from a stainless steel sink and I'm very pleased. Fluids move towards the drain with rounded corners so no food sticks. Straightforward installation. A great custom look!
