Many mirrors that we install are custom cut to fit a specific opening. Mirrors above a vanity, like in this image, are very common but they are all slightly unique.
This installation was unique in that we had to measure the exact location of the electrical outlet as well as the electrical boxes for the light mounts. This is a great bang for the buck as the lights look like they are growing out of the mirror.
We also laser measured the exact height and width of this mirror to line up with the height of the cabinet on the right and stop flush with the edge of the backsplash on the left. The end result is a perfect fit to compliment this master vanity.
