This is an incredible, modern stand-alone sink for the price!  Arrived quickly.  I'm taking away a star because it needed some creative workmanship as the back of the unit has three holes for plumbing which did not line up to regular plumbing heights.  My builder cut two lines from the bottom of the first hole through the top of the second hole to open up the space for plumbing (see photos)--it worked!  Also it is a hollow unit but has a wide enough lip at the bottom to apply silicone to the floor.  You can also add weight to it by inserting concrete or weighted material incise but not needed.  I purchased the Delta faucet, mirror and soap dispenser as seen in the photo from Wayfair as well.  Love the look!
