Product Reviews
Rated 5 out of 5 by 2 reviewers.
Rated 5 out of 5 by Great Sink I bought this for our office kitchen remodel. I needed a small 2 bowl sink that looked great and was easy care. The color is beautiful and the sink is well made. I also liked that it can be installed as a drop in. 5/4/11
Rated 5 out of 5 by Blanco bar sink These granite sinks are awesome. Just put one in our wet bar area, and also have a larger one for our kitchen sink. They wear like iron, are easy to clean, don't absorb food bacteria, odors, or discoloring. I chose the grey color. Very classy and more upscale looking than stainless sinks. Had it installed as an undermount sink in a granite countertop. 7/24/11
