Blanco 440179 Reviews

Rated 5 out of 5 by from Can't do better than this I bought this sink in 2007 for my new kitchen, and of all the things I got for that kitchen, this is the best. I can lay a 14" cast-iron skillet completely flat on the left side, and still have room for other objects. This makes cleaning large pots and pans a vastly simpler task. A friend bought one on my recommendation and she agrees with me: The Best. It's easy to clean and always looks good due to its very clean, uncluttered design. My wife likes it for her potted plant care, too, as the depth gives her the room she needs to tend them. An outstanding product!!!

Rated 4 out of 5 by from super sink I love the size of this sink. It is much deeper and larger than our last one. However, it created a number of problems with installation. I like for us to do it all ourselves, so hiring a plumber was not really an option. A plumber probably would not have had a problem. Since the drain is not located in the CENTER of the sink AND the sink is DEEPER, all plumbing had to be customized. Our current pipes come out of the wall too high and stuck out too far, so those needed serious adjustments. After a great deal of time, and several trips to our local hardware stores, we were able to phenagle a good plumbing job. I still love the sink! My neighbor and parents also have one.

Rated 5 out of 5 by from Blanco Silgranite II sink Met every expectation and looks good with our granite counter top. Lighter than I expected which is a good thing. Got the matching basket strainers also. That seemed pricy but it is a good color match to sink.

Rated 5 out of 5 by from Great Sink Reading other reviews helped me decide on this sink, and I'm glad I read them. I LOVE my sink! It replaced an enamel top-mount sink of approximately the same proportions. But this sink is so much better. First, I love the black color - perfect with the new granite. Second, I was able to keep the same bowl dimensions..the bigger bowl being perfect the soak/clean my very large soup pot. The good and bad of it is that the sink doesn't show any dirt/grime . I have to clean it because I know that I cleaned my spaghetti sauce pot (always leaves red greasy film) in the sink, but you can't see the film! Again, both good and bad (ha!). I've been using it for a little over 1 month and I can't fnd anything wrong. I certainly recommend it to anyone looking for a granite-composite sink.

Rated 5 out of 5 by from Blanco double sink I just got my sink installed. It is huge compared to my last stainless sink. As beautiful as the sink is, the drains I got were black to match and were kind of plastic. However, they look good as they match and don't stand out. The right side is small for a small dish rack to fit into so you might want to order one to match if you need one. I also have a plastic sink protector in the bottom. I understand that these sinks are very hard to scratch. I am so excited to have a sink after many months of self-installing a kitchen.

Rated 5 out of 5 by from Love This Sink I just purchased a new home and needed to have the kitchen updated. As I was looking through all the different sinks i fell in love with this one. I like the idea that you can purchase the grids that fit in the bottom of the sink which i like. I also purchased the stoppers that match the sink and love the look. I really like the fact that it can be an under counter sink so with the new granite it looks great.

Rated 4 out of 5 by from MOST BEAUTIFUL SINK EVER Remodeled my kitchen and purchased this black sink to compliment my new quartz countertops. Absolutely love it. It looks so nice with no visible scratches seen after washing the dishes. Has a great sheen to it and it always looks clean. I have to remind myself to clean it. If there was one thing I would change, I would like the big and the small sides switched as I do most of the cleaning on the right side and the drying on the left side and having the left side so large that it encourages more dishes to be put there instead of dried and put away. Love the sink and highly recommend it.

Rated 5 out of 5 by from great kitchen sink We are very happy with our purchase of this sink. Although it has been in use only a couple weeks, our satisfaction of our decision is very high. Easy on the eyes, easy to keep clean and the durability seems to be excellent. We might change our minds after a couple years of wear and tear, but at this stage we are very happy.
