This medicine cabinet is higher quality than what you will find in stock at Home Depot or Lowes.  The interior (recessed shelving) is a metal with an enamel coating--not particle board.  You'll also notice that many of the frameless 30 inch width cabinets only come in standard heights of 26 or 30 inches.  This one is a unique size in that it is 36 inches in height which provides additional mirror and storage space.
