Installation of this sink was extremely easy, as it fit right into the existing hole from the old sink. The original sink and faucet were builder grade, this Kraus is heavier gauge and much better quality. Sink was installed with a Pfister touch-less faucet, and the combination looks amazing! The most difficult part of the installation was moving the poorly designed existing drain plumbing to accommodate the rear drain locations. As you can see, it was definitely worth the headache! We highly recommend this sink for anyone who is interested. The sink comes very well packaged, the box was damaged in a couple places, but not so much as a scratch on the sink. Very impressed with the Kraus brand! The potholder and oven mitt are also nice freebies!
