Divided basin sink.

I've owned many homes and have never been so happy with a sink as I am with this one. It's spacious, easy to maintain, doesn't show scuffs, water stains or food dye transfer. The material and color are perfect with my new quartz countertops. It's beautiful to look at and a pleasure to use.

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!!!!

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.
