brutuses -- Can you dim these? I love the 'glow' when our sconces are on dim. I haven't gone to CFLs, waiting to see some that can be dimmed...also unhappy about the mercury problem they present. Yeah, I'm a hanger-backer about new and improved anything. (I really need to replace the Flex-Seal pressure cooker, though. LOL)

Another issue - sconces don't give off great light for makeup application. I would suggest a small recessed light over each sink as well or some additional lighting for makeup (a wall mounted lighted makeup mirror, etc.)

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.

A bathroom needs a GFCI receptacle that is easily accessible by the vanity, but any additional receptacles in the room are optional. I usually use only one GFCI receptacle circuit, but always make sure there is one wall receptacle on the circuit near the entry door (for a vacuum cleaner, etc.). Based on the current popularity of fancy commodes (with bidet, etc.) I may start putting a receptacle near the commode. The counter height GFCI receptacle on the vanity side wall meets the basic requirement for a bathroom. I would probably just move the double GFCI receptacle on the long wall down to standard height and leave it there. That might also be a good location for a heated towel bar. Where to put the sconce is a combination of esthetics and electrical requirements. Most fixtures can be located as close an an inch from a side wall, but might look funny that close. You also need to work around the placement of the medicine cabinet and the swing of its door. The attached picture will give you an idea of what you might need to consider with sconce and medicine cabinet placement. If you look closely you will see that the medicine cabinets are slightly off from the sink bowl center, since that is the only easy way to make them fit with the three sconce lights. The placement of the sink bowls is determined by the vanity (cannot be changed), but lining up with that sink centerline would have cut into the space needed for sconces on each side. The sconces could not be moved farther out because they got too close to the window on the left and the wall on the right. Bruce
