I face a very similar dilemma due to plumbing and ventilation systems in the wall behind my vanity. Also, there is a pocket door in the wall to the immediate right of the vanity. To the left of the vanity is the toilet. My floating vanity is 36" wide and 24" deep. The bathroom is 6' x 10'2". I however have decided to use an overhead vanity fixture with a center projection of 4" - 5". I found it helpful to look outside of the options available in bathroom lighting for overhead sconces. That is, wall lights and sconces that may not be rated for damp areas. I do not know if this option will work for you, but it does increase the selection size. In my case, I may or may not need the additional lighting from an overhead sconce, but I have been told one can never have too much lighting around the vanity mirror and the key is to have enough lighting so that there are no shadows on the face. I have one overhead low-voltage can over the sink and another one a couple of feet before the vanity. I also have another wall light mounted beneath the floating for ambiance. I have another low-voltage can over the toilet and another one in front of the toilet. There are also two low-voltage cans over the tub/shower combination. The only other light source is a 5'6" x 12" sandblasted clerestory window above the tub/shower combination. The bathroom walls are 18" bands of off white limestone (crema europa) with 3/4" bands of brown granite (antique europa). Floor is antique europa. Ceiling is same limestone with a 6" border of labrador antique. Kelley kdockrey@adelphia.net

Cbusgirl41:. Sorry for the delay in my answer. My vanity is 72" wide and inset into a nook. The thing that threw me off in my planning was that I didn't plan on having to align the sinks into the middle of the base cabinets, not getting to choose where to place them on my own, so that was why I ran into the same side sconce alignment challenge you are facing. In the close up photos, you can see my 36" wide frameless mirrors are slightly offset from the center of the sinks (again, the sinks!!!!) Apparently, the lesson learned and advice for everyone is to be mindful of the sinks!! Nothing that a few strategically-placed accessories can't fix! The frameless option with the arch gives it sort of the pivot look without the extra baubles. I was going to frame oval custom made mirrors, and, in the end, I love the simplicity of what I now have. I do NOT have supplemental overhead lighting in the vanity area; however, those on a dimmer would have been a nice addition. It's not a problem, because even at night, I have plenty of light and it's rather soothing. Plus, the drywall was already in and finished so I didn't want to have more extras! There is a lighted, heated fan light over in the middle of the room by the shower/tub combo which is to the right when looking from afar towards the vanity. May_Flowers: I am personally obsessed with the side sconces for their ability to "flatter" now that I am reaching a certain age ;-) I am trying to add photos (hopefully not upside down this time!). Hope you can read the dimensions and see the scale. The tape measure in the photos starts at the left wall.

Well, we settled on mounting the center of the fixture (the round part that mounts to the wall over the electrical box) at 63", which then puts the very top of the fixture at 70" and the center of the light source at around 67". I sure hope I made the right decision. The contractor/designer's suggestion was 5" taller than the 63". That just seemed too high for me. The electrician has set the electrical boxes and the piping for the wiring, but I'm still second guessing myself. Yikes!!!

If you do 4 sconces, 2 for each mirror, it will make each mirror seem its own entity, IMHO. If you do a double sconce in the middle, it seems like.....an after thought? And the sconces will not be equidistant from each other and the mirror. My OCD kicking in, I suppose. If the space between is larger than the mirrors, I think you should go with 2 separate sconces. If the space is smaller than the mirrors, I think you could go with a double light. Just make sure the spaces are fairly equidistant.
