Blanco 441223 Reviews

Rated 2 out of 5 by from Disappointed This sink was recommended to me by a kitchen designer at the lumber yard my contractor uses. I was concerned about purchasing a light-colored sink (because of the potential for staining), but the sink looked very nice with the quartz composite countertop that I purchased, so I was initially pleased with the purchase. That initial impression changed. I've had the sink in since May 2012, and I constantly find myself fighting stains in the sink. I'm surprised to read the other two reviews about this sink that allege they have had no problems with stains in their sinks. The only way that could be is if they simply don't sit anything in their sinks or they constantly clean them. Also, the baskets/strainers that were ordered to supposedly fit and match my sinks were $50-$60 each. They won't seal and hold water unless you hold them down! The rubber gasket that sits into the drain of the sink above the garbage disposal falls into the garbage disposal periodically, so I expect it to fall victim to the disposal and get chewed up one time that I'm not vigilant. For the price of this sink and the strainers, I expected MUCH better quality. I wanted to upgrade my kitchen and paid to do so, but feel this was not an upgrade at all. This is no high-quality sink--definitely high cost, but not high quality. Between the color/staining problems, the inability to get the sinks to hold water, and the problem with the rubber gasket above the disposal, I would NOT recommend this brand and color. Learn from my mistake.

Rated 5 out of 5 by from Love my new sink After considering many styles and colors of sinks for my remodeled kitchen, I am 100% pleased with this one. It does not stain and cleans up in a flash. The warm biscotti color blends with my counter top and backsplash.
