The mirror in your bathroom can have a dramatic effect on the design details .You really have to consider the size of a bathroom mirror. You have to measure the vanity that the mirror will be installed above because a mirror that’s larger than the vanity will look awkward.
To avoid water stains, consider sizing the mirror so that it starts about six inches above the vanity. Don’t let the mirror go over the edge of the vanity.
Now you can perfect perfection!!*
