I would want mirrors above my sinks.

Are you going to be changing the vanity?

Not changing vanity

You could consider pivot mirrors. They come in vairous shapes (round, oval, square, and rectangular), and sizes. I purchased Minka Lavery pivot mirrors ( wonderful quality) and I love them.

Looks like you have double sinks on your vanity. I would prefer a mirror above both sinks. Two people brushing hair, or teeth, etc etc etc, each need their own mirror, not both crowding together to use one mirror.
