    • Cool shape sink

      Really nice sink, I just kind of wish it was a bit brighter/shinier white. I'll update when we install it. I think it will look great.

    • Great room for small sink but ...

      As described, and it was nice to have a chrome button over the overflow. But, alas, the back wall was curved behind the button, which would look weird in teh cutout and the two circles aren't aligned, so either the over flow or the drain hole are off center. I have to return this as defective.

    • Wrong Lavatory

      I'm sure this lavatory would have recieved a very high mark frrom me since I did a lot of reading of reviews before my selection. Everyone wrote a glowing responce to this sink. I'm sorry to say I was shipped the wrong lavatory which is smaller. The mistake was not noticed until after the granate intstallers had it already set. I only did a eye inspection and did not take out my measuring tape to confirm the proper size. It was only a matter of inches, but inches matter in bathroom sinks. I'm making due with the sink sent and Overstock has compinsated me the diffrence plus an additional shopping credit. I would much rather have the proper sink but Overstock did the best they could save sending me the proper sink, paying for a new counter top and labor for the installers. I only hit the rating star and the no because it is mandatory to rate, this is no reflection on the lavatory. I will continue to use Overstock but I will be paying much more attention to the items sent!

    • master bath sinks

      I loved the rectangle look of the sink and the depth. My new master bath is very contemporary and the look was exactly what I was looking for. They were packaged very well and I WILL CONTINUE TO SHOP OVERSTOCK before buying local!

    • WONDERFUL sink

      We narrowed the cabinet in the guest hallway bathroom to a nonstandard width that would visually 'widen' the small room and then discovered that the existing sink and all others available at the 'big stores' near us wouldn't work to sit and still leave room for the faucets between the sink and the wall. We found this one and never looked back. It looks wonderful. We like the rectangular shape, especially in the narrow counter. We may even get another for the next bathroom redo!

    • Not too large once installed - just perfect!

      From some of the reviews we were concerned the sinks would be way too large for the master bath vanities. Once undermounted in the granite countertops they give a boutique hotel feel. They are certainly not deep, but perfect for regular daily use.

    • great sinks

      we ordered 2 sinks for our bathroom and couldn't be happier with our purchase. The sinks arrived promptly and were extremely well packed. Everything was supplied. The sinks look great with our granite countertop. They fit well with our vanity which is little narrower than average. Would purchase again from overstock.

    • Great Sink

      I wanted an undermount that was not oval or round for the master bathroom. This is a great choice. It looks great with a granite countertop. I ordered this sink and it came so quickly I was not ready for it yet. I would order this sink again.

    • Great sink for long and shallow vanity

      We replaced the top on a long (6') and shallow (18") vanity and struggled to find an undermount sink that would both fit and allow room for the faucet and overflow. This one did the trick and looks great under our granite top. The rectangular shape is also a nice change from the typical oval, and the quality is consistent with much more expensive options.
