Great Sink!

from La Grange, TX on 10/30/2015 – Verified Buyer

We went a little outside the box with this sink and we weren't sure if we were going to like it. We had just redone our counters with Silestone and wanted something different than a white porcelain or stainless sink. We have hard water so we were a little concerned about spots...but so far we haven't had any issues. When the sink dries it doesn't have spots. (Picture - before the faucet was installed)

Pros: The sink is deep - great for big pots.

Exactly what I was looking for!

from Cary, NC on 01/04/2016 – Verified Buyer

I did a full kitchen remodel. Ordered the Blanco 32" x 20.84" bowl undermount sink, the two stainless sink grids for each sink and the Bridgeford Single Handle Faucet (pull down spray). All of these products have held up great. Not a scratch on the sinks - the holes in the grids work great for the disposal! These are definitely worth the investment and something that I will order for my next home!

Pros: Easy to install. No problems.
Cons: None

from Wadsworth, OH on 02/05/2016 – Verified Buyer

My granite company specified using an undermount sink (instead of a dual mount) and most of the ones I looked at were over $400.00.
This is perfect for my kitchen - beautiful color (biscotti), right size (60/40), and very high quality.
5.0 stars

from Williamsburg, VA on 08/26/2016 – Verified Buyer

I love the granite composite sink. I debated between stainless steel and granite composite. I choose the granit composite because it is so much easier to clean and it is not nearly as noisy as stainless steel. I couldn't be happier and have gotten plenty of positive comments.

My sink hasn't even been stalled yet, and I know I will love it. We are moving to a new home and because I love my Blanco silgranit sink in my current home, I definitely wanted another one. They are the best!
