The delivery was a dream but when it came to installing the vanity, I can’t understand why the vanity is 36” but the Backsplash they give is 34”??!  Makes zero sense at all and I had 2 builders look at it- neither can make any sense of it.  
Watch out for the written specs- it does say black splash is 34” even though the picture looks like the splash is the same length as the vanity.  
Wayfair handled it very well though so I was pleased at least with their service.
