Bathroom mirrors

I like all these, but noted my top 3 (or 4) choices below their pictures. Now that the vanity is installed and sinks are in place I think the mirror might have to be closer to 20" wide. The center of each sink is 16.5" from the wall, which means a 24" mirror will have 12" on each side of the center line. With 16.5" to start with then 12" of mirror we'll only have 4.5" for the light. A 20" mirror will give us 6.5" for lights.
