    I was looking for a sink that would bring drama and also coordinate with glass block windows near by. It works wonderfully. Sink is solid glass and weighs 80 lbs so we had to pay attention to the pedestal strength.

    I bought two of these beautiful sinks and have gotten nothing but compliments on them. A plumber said he has never seen anything like them!!! I love that I can find items at Overstock that can't find anywhere else/1

  • Good product but terrible quality control
    Verified Purchase

    This thing is gorgeous. It's really heavy. But you didn't need me to tell you that! I ordered this item based on the good reviews here. And this item is certainly worth it. But what got me was the terrible quality control of this item. If you order this, be sure to carefully and closely check the sink as soon as you get it. I had problems with not one, not two, but three pieces in a row! And do not drill the hole in your countertop for the drain until you finalize the exact orientation you want - two of the four units we received did not have the drain hole perfectly centered in the middle. You can skip the rest of the review below unless you want the gory details. A shout out to Overstock though for efficiently and painlessly handling the returns in all 3 exchanges required. First attempt: Sink arrives with no damage to box. Upon opening, there is a very prominent and visible dime-sized crack on a corner. Since this is an expensive, clear, glass sink this one had to be replaced. The manufacturer does not want the broken one back so I have to worry about discarding a 70lb glass weight. Second attempt: So the supplier, who happens to be 7 miles from my location, ships the replacement via 2-day air (thanks though for thinking about the "fast" shipping)! The 2nd unit has about a dozen small bubbles just under the top surface clearly visible. Another call to Overstock, and this one is on its way back. This time, I explicitly request that the shipper carefully inspect the replacement so that I don't have a problem again. This time, the supplier wants the defective unit back, so I have to lug it back down myself and box it up for UPS. OK, no biggie. Third attempt: Unit again arrives with no damage to box. I open it immediately only to find a large and even more prominent quarter sized crack in one of the corners! At this point, had we not already drilled the drain hole in our countertop in a specific off-center location based on the size and shape of this particular sink, I would have simply given up on this sink and bought something else. But I was now stuck and had no option but to call Overstock a third time to return the sink. The supplier did not want this one back either, so I had another 70lb dead weight to discard. Fourth attempt: Box arrives, looks good, and - surprise - this one is actually good with no problems for the most part. I accept this one, call my contractor back (he had finished everything else and moved on), and the bathroom does look gorgeous now. But what a nightmare packing/repacking and lugging a massive sink up and down so many times!

    I looked at this vessel for months at many different places on line. I was shocked at the prices I saw and knew I could find a better price. At O I paid over $400 LESS than other sites. The vessel is beautiful and makes a spectacular appearance in my redone bathroom. It is totally unique. My contractor that was remodeling the bath kept saying what a custom look the bath had and was unlike any other he had done. If you are looking for a WOW factor for your bathroom and vanity, this is the vessel for you. I put it on a white quartz top with a chrome single vessel filler faucet. I love mine and if you're looking for something that is not the same old cookie-cutter bathroom, This is the vessel for you. Go for it!

  • Q:

    "I am looking for suggestions on what to mount this sink on. pedestal or other unique ideas. Thanks"

    • A:

      We are mounting our sink on a vanity cabinet that came with a sink top. We did installed the cabinet without the top, added some 3/4 inch plywood and will be installing a slab of black granite on top with the sink on top of this. Good luck.
