The delivery was swift.
You need to know:
you do need a plumbing , due to the drawer under the sink location the plumbing needed to be  raised to clear the drawer.  Also, for ordering, though specified detail information is provided, specific dimensions of where to locate plumbing is not.  
The best is to make sure you order your unit earlier enough in the remodeling process so the plumber can make relocation of such pipes, otherwise, you may find yourself modifying the cabinet or drawers.  Which then you need a carpenter.
