we are replacing the large mirror behind the double vanity with framed mirrors that are really medicine cabinets (we need the storage). my husband is 6'4" will the 20x26" mirrors be too small? Should I go with the 24x30"? We really don't want to build a tower in between. vanity is 70" long, 35"high. We will move the lighting down or go with sconces (which I understand is better lighting for a bath anyway). Photo is of the space with news paper up in the size of the smaller one. Does it look too small? I'm leaning towards the bigger ones. Thanks!
