Blanco 440181 Reviews

Rated 1 out of 5 by from Not Great I've had a Blanco Silgranit sink in white for 5 years now in my laundry room. We really only wash our hands in it. I love the size shape and depth. Hate that I cannot get it clean with anything including their special cleaner. It looks like and old bathtub. My sister-in-law has had it in black for 7 years. It is also stained and the stains will not come out. Too bad. They look beautiful but definitely do not stay that way.

Rated 5 out of 5 by from best sink for the money When looking at all our options, stumbled across this Silgranit sink and when I researched it, all the reviews said this was the best way to go. Have had stainless and porcelain enamel in the past. Have had the Silgranit now for over a month and the sink has lived up to the reviews. First - the color is great - looks great with our granite and the larger size has been great too. Wanted a double and the offset sizes are very functional. Second - easy to clean - our old enamel sink scratched and stained very easily, and you had to scrub it, use abrasives to remove scratches and stains - it was a pain to keep looking nice. This one, it doesn't really stain wipe with a damp cloth and most everything comes off. Blanco makes a sink cleaner that I've used to remove some of the scratches from metal pans and it works great - much easier than the enamel sink. Third - No gouges and I've dropped all sorts of stuff in it - actually broke a stone baking sheet in half when I accidentally dropped it in the sink - no gouges from the stone. Fourth - hot pans - no problem - no char marks or gouges. Lastly - value - I've never replaced a sink, so I was surprised at how expensive they can be, especially the stainless steel ones. The size, the shape, the durability, in my opinion, makes this the best sink for the money - highly recommend

Rated 5 out of 5 by from Best sink ever I have had this sink for 3 months and just love. First I thought it was too big, but it's not. Right side is perfect for quick small cleanup jobs, large side for your big items. I did purchase the recommended Blanco cleaner keeps it looking new.

Rated 5 out of 5 by from Great sink We purchased this sink to replace a Transolid Acrylic sink that cracked. The Blanco is head and shoulders better and the install was mostly straight forward. My plumber was not at all interested in knocking out the 'knock outs', so I had to do it. We followed the directions provided by Blanco and they did 'knock out' with a ballpeen hammer. It is nerve racking, but it worked without incident for me. Sink looks awesome and the matching strainers are also nice. The transaction with Faucet Direct was also smooth and without incident.

Rated 5 out of 5 by from Blanco sink I love my new sink. I like the depth for doing large pots/cookie sheets, and filling large wash buckets. Smaller items I use the smaller sink. Holds up well to whatever I put in it.

Rated 5 out of 5 by from Beautiful looking It not only looks beautiful but cleans easily. Left sink is super deep and is great for large pots.

Rated 5 out of 5 by from Great sink I love this sink! It's big and deep. I can fit all my skillets and pans in the large side. I have had no issues cleaning it. It's a wonderful sink and it was $200 dollars less than the one the granite guy offered. It matches beautifully. It was a wonderful purchase.

Rated 5 out of 5 by from Great design Lightweight but so strong. Easy to clean, very durable. The undermount makes keeping the sink and counters clean so much simpler
