I'm about to redo my small 3-pc. bathroom, and picked up the new mirror and 2 sconces already (saved about 75% on regular retail!!). My vanity is in a 42" wide, shallow alcove and I currently have an oak medicine cabinet with a built in lighting strip, so the electrical box needs to be moved.
Question: how high should I place the new boxes in the alcove? The sconces are 11" h x 4"w (shades hang down), and the new mirror is oval and 23"w x 29"h. I don't want to cut into the wall until I know that the lights won't be too low or high to look 'right' for the proportion of the tall, narrow space.
