Awesome sink.... gorgeous sink for a GREAT price!!

So I bought a Blanco 440220 (black granite, double-bowl) sink from Quality Bath. I was promised that 5-6 business days after my purchase, the sink would ship out to me. When it was actually shipped out to me in 5 business days (directly from Blanco, the sink manufacturer) and arrived at my home the next day via FedEx (thank god, no UPS), I was pleasantly surprised. When the FedEx driver delivered it to my door, we opened it together to check for damage before he left. I was again pleasantly surprised, by how well Blanco had packaged it... ensuring that the sink was absolutely flawless (and beautiful!!). Add to that, that the sink that I nearly bought at The Home Depot for $386.27 (including tax & free shipping), was only $284.50 (total including no tax and free shipping) here at Quality Bath. This was definitely a win/win... and I will GLADLY do business with Quality Bath again in the future. Thank you!!!!

I was spoiled (I thought) before by my deep double porcelain sink in my previous house. We recently bought another house with one of the standard contractor grade, shallow stainless sinks. We decided to replace the white ceramic countertops and upgrade to granite. A friend mentioned granite sinks and I had never heard of this. I researched and discovered Blanco sinks. These look great and matched the incoming granite seamlessly. We went with a black, really deep, undermounted double granite sink and it looks awesome. It is very tough and super easy to clean. I don't worry about chips or marks at all. I don't see ever going back to anything else and if I upgrade any more sinks, they will definitely be granite. Well worth a little extra money for the look and usability. Jeff

I had my Blanco sink installed about 15 months ago. I love it!

I had my Blanco sink installed about 15 months ago. I love it! It replaced a stainless steel sink. It looks so much nicer and cleans up easily and beautifully. I chose a contemporary style for my contemporary kitchen and it couldn’t be more perfect against my black granite counter tops.
