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.

Sink Is Beautiful!!

I did not want a plain ordinary stainless steel sink that your eye was over come by... I have the sink in a good size quartz slab and if flows so beautifully so all the kitchens beautiful features are balanced and stunning!!! The no divided sink is such a blessing! We use the dishwash for everything it can fit. We have hooked up a garbage disposal to the drain, just in case we ever really want to use it.. which we try not too. BTW... This is my no my first Karen Quartz sink... Love them!!!!
