I love, love, lover this mirror and would have given it 5 stars if the dimension information on the website was correct. The dimensions are listed as 30x57, however, that does not include the hardware that the mirror hangs from, only the dimensions of the mirror and frame. Because of the additional 6 inches for the barndoor hardware, I will have to purchase a new light fixture that does not cover the top of the bar. Also, if you do not have a "handyman" background, be prepared to hire someone to hang it for you. Even my contractor, whose been in business for 20 years, said it was much more difficult than he expected.
