We're building and have separate vanities in our master bath, both 72" wide. The framed mirrors we've chosen are 46"wide by 36"tall, ceilings are 9 feet. I'm thinking of doing a 4-bulb vanity light above each mirror with sconces on either side of mine. Would this be too much? I'm afraid since the sconces will be approximately 58" apart they wouldn't provide enough without an over-the-mirror light. Thanks for any help you can offer.
