I have not installed this yet but am speaking to the extreme difficulty in moving this piece of furniture. It was delivered inside of my garage as the plan was to leave it there until we needed it in our upstairs master bathroom. Three weeks later we unboxed it, only to find that it is fully assembled and completely unable to separate the top marble counter with the bottom. We had 4 large dudes and could literally not lift this enough to be able to move it, and forget about getting it up the stairs. This will require extreme care to move around your home and is basically IMPOSSIBLE to get up stairs. I can't believe any company would build something that you couldn't move in pieces. This is more difficult to move than a washer or dryer, dishwasher, or fridge. It is literally harder to move a refrigerator up stairs than it is to move this thing. Not happy.
