This came in a corrugated box with a wood box over that!  It was easy enough to install with two people.  The top rod directions says take your opening and 60" cut the difference off.  You can error on the side of too much vs. not enough.  Otherwise it went in without any problems, looks amazing.  I took Flex Seal clear adhesive and caulked it along the wall and tub for the stationary glass.  Worked great looks clean and no need to drill a hole in my tub.  I also did not use the clear splash guards or the metal channel that came with it.  I wanted a clean look.  overall VERY happy with it!
