Blanco 440220 Reviews

Rated 5 out of 5 by from Best Choice Ever! This is my third kitchen sink. The first was stainless, it stained and scratched. We remodeled and put in granite counters and an enameled caste iron sink. Big mistake; it stained and scratched. After much research, I decided to replace it with the Black Blanco double bowl sink. It arrived very timely and in perfect condition. Although my husband is not a contractor; he was able to install the sink with no problems. I am so happy with my Blanco granite sink! It looks beautiful in my white/gray speckled granite counter. Cleaning is easy. We have hard Artisian well water, but the sink does not water spot. I love to cook in caste iron pans and now I don't have to worry about stains and scratches. This was my best purchase ever!!

Rated 5 out of 5 by from Blanco Sink We installed this sink in conjunction with the installation of new granite counter tops. The sink looks great, the installation was simple and most important the wife is happy with it. The sink is much lighter than the cast iron and porcelain sink we had before. Although the sink sat lower in our cabinets due the it being deeper and doing an under counter mount, the plumbing went smoothly and I only had to buy a couple of pieces to make everything fit perfectly.

Rated 5 out of 5 by from Great Buy! Love the sink, perfect sized basin's on each side. Love the look of it in our kitchen. The only down side to it in our kitchen is that we don't have very soft water so if I don't clean the sink out well we get water spots on it.

Rated 5 out of 5 by from Very nice I really love this sink it's perfect depth, it's perfect color I love that it's equal sides so my faucet can get both sides of the side. I am very happy with this sink and very happy with faucet direct and how excellent their customer service is. I had gotten a different sink that chipped and then also noticed it was not equal sides and they helped me fix it super quickly and they were super nice.
