This is a beautiful smaller vanity.  I purchased it because it would fit in a tight space and had two storage areas.  Unfortunately, the plumber informed me that the size and alignment of the pipes will not only necessitate the removal of the shelf in the top part, but the back panel of the drawer will also have to be removed to allow for the space needs of the plumbing.  Since it would cost too much to return, I will now have a nice looking vanity with no storage.  Advice: check with your installer and/or measure everything very carefully.
