Blanco 440174 Reviews

Rated 5 out of 5 by from Beautiful! We love this sink! It's beautiful and extra deep. The color looks great with our new Mirador Gold granite countertop, pulling in the dark grays and blacks from the matrix. It replaced a huge, top mounted double-bowl sink, which overwhelmed the space. Also, since we were splurging on a new granite countertop, we didn't want to cut such a large hole, and this was the solution. The size and shape look perfect in the space. The single bowl is huge, similar in size to a laundry tub sink (but MUCH prettier). My largest cookie sheet lays down flat in the bottom. It's so deep that you almost don't notice a few dirty dishes sitting on the bottom. Since we no longer have a double bowl sink, we use a drainer pad when needed and can put that away instead of looking at a huge permanent hole in our granite. We installed a new stainless steel pull-down faucet on the upper right hand side of the sink and installed a stainless steel drainer. Here is a photo, backsplash not installed yet. I will try to upload another photo when all has been completed.

Rated 5 out of 5 by from Beautiful Looks great with our black appliances, faucet and crown moulding in the kitchen. It is so easy to keep clean, easier than stainless steel. Very hard surface, doesn't get pan scratches.

Rated 5 out of 5 by from Beautiful sink and great service I originally ordered a larger single basin sink but it arrived broken and I it was HUGE. I immediately called FaucetDirect and received a refund for the sink and re-ordered this smaller sink. It arrived quickly and in good condition ... The finish is very smooth, unlike many other granite sinks that have a bit of a bumpy plastic feel. The size is just right for my corner sink!

Rated 5 out of 5 by from Beautiful sink I love the finish on this sink. In my last kitchen I purchased a black sink from Lowe's and was very dissappointed. This time I have the perfect sink! Not too big, not too small. Deep finish, looks rich, cleans easily.

Rated 5 out of 5 by from Blanco single basin undermount sink. Love this sink! However, you do have to be sure you have room for your faucet. I wound up putting my single hole fixture on the right side of the sink and I like it that way. On a regular depth counter top there is not sufficient room behind the center of the sink to mount a faucet. The extra depth of this sink is great for laundry or washing doggies.

Rated 5 out of 5 by from Perfect Sink For Mudroom Purchased this sink for my replace a very-much used and 20 yr old utility sink. It is amazing and looks beautiful. It is deep enough to wash air cleaner filters and wide enough to throw laundry in it as well. I love it! Easy to clean and is sleek and modern...looks great with my new granite countertop.
