The cabinet was just what I wanted and looked so good in the chosen corner of the kitchen.  Took hours on the internet to find a cabinet to fit there. Had to be shorter than usual for the space..  The side measurement was advertised to be 12.5 inches. Perfect.  No.  It was 17 1/4 inches.  See the diagram with measurements.  The arrow is clearly on the top and not the inside.  Wayfair reimbursed me immediately and were so polite about the mistake.  I had only a 15 1/2 clearance .  If placed in that corner, the only one available in my apt. kitchen, I cannot open the drawer or cabinet next to it.  And oh the white color and height were to be so perfect.
