Don’t get me wrong this is a nice looking vanity.  What I don’t understand is the tiny home in the back for plumbing.  How will I put this against the wall and put the top w sink on, then plumb it w PVC piping.  Seems impossible without cutting the hole larger so I can see the plumbing from below. 

Maybe I’m wrong (and if so please let me know) but it seems that a larger plumbing hole that includes a gap at the bottom would be helpful for installation and future maintenance with having any negative effect on the look of the vanity.
