Just installed it yesterday. Not an easy job as plumbing has to come through the wall and not the floor. Access to the plumbing hookup is through the front and very limited. The backsplash was damaged.I contacted Wayfair about the damage and they responded immediately and are sending a new one. 
It is not flush with the wall as the legs extend beyond the back of the vanity. 
I really like the style of the vanity and once installed, I am basically happy with it.
