I really liked the advice you offered at Houzz in 2014 regarding the bathroom sconces and their height from the floor. I would send you a photo of the pic you posted to illustrate this but this form will not allow it. I have the very same problem and the very same sconces. As it is, I have the sconces mounted so that the bulbs are at 63" (I'm 5'8" tall). Do you remember the height at which the base or bulbs of those sconces were mounted and what part of them was used to determine the midline of the mirror? Any help will be greatly appreciated.
