This is a 2.5- terrible design- would not have ordered had we know that 1) the counter sink comes attached, and unable to remove- moving this up 2 flights of stairs was ridiculous. And 2) the counter does not have an over hang at the back and the backing panel is screwed on the outside there for sits 18. An inch farther than the counter. We had to remove it in order to get the vanity flush with the wall. Super disappointed In this product as it was costly for what is it and design flaw after design flaw. If our Reno had not taken so long from delivery of this to installation I would have returned this beast before moving it up the 2 flights of stairs.
