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.

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!!!!

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.
