We currently have a 60" vanity with overhead lights. Our bathroom is 5' x 10', and I read that I need 300 watts of light for that size bathroom. I'm sold on sconces for our remodel because of our aging eyesight. We'll have two sconces with one sink. I've looked at all kinds of mirror configurations, but what makes the most sense is to set the sconces into a large mirror so that the light is bounced around the room. Did you say in another post that your ceiling is only 7 1/2' tall? I'm not sure a chandelier would look so good. I think they're better in powder rooms and in spacious bathrooms. Instead, I would use an exhaust fan/light combination to put light and ventilation over the toilet and shower area. I wouldn't count on the vanity lights, door, and a decorative chandy to supply enough light for the other side of the room. You need light for cleaning the toilet and shower and if anyone reads while on the can.

Well, I am trying to make similar decisions on this myself. I too had come across that it is better to have sink lighting from the side rather than above but have found the layout to be challenging and busy. So, I checked houses for sale with 2500 - 3500 square feet and none of them had side sconces around their mirrors. And only one or two had frames around their bathroom mirrors. Most of them had one large mirror across the sink area with lights over it. A bathroom can be a busy area, so from a minimalist standpoint, no frame. Now a mirror in the Livingroom really needs a frame.

One thing to keep in mind if you're going with Theresa Peterson's recommendation is location of any power outlets, if you have any - need to make sure that they remain accessible. You can always hang the mirror(s) above them, but then the mirror(s) may be too high. I have that issue with my currently remodeled master (this is the "before" photo) - because of the power outlets, and because each mirror needs to be centered with its respective faucet, I cannot do wider mirrors (even though I have the space, theoretically):

Context is key. Bathroom size, style, wall type and space all factor in. Post up pics for best advice.
