Great quality, but very heavy when carrying it up a large flight of stairs, took 3-4 guys.  The marble top does come off, I saw some reviews that said it didn’t.  The first one we ordered, the marble top was cracked in two places. Wayfair was great and sent another one but it took a month to arrive.  Really solid piece and looks fantastic in our black and white master bathroom.  We can’t use the internal electric plugs feature, as we have no wall outlet behind the unit.  It cost more than we had budgeted but, glad we chose this one.  The “white” marble top is not a true bright white, a little cream in it but doesn’t clash with white subway tile.
