We are currently building a house. It is Mediterranean style home. We now just have a mirror going up with a granite back splash and two columns on each side. The shower is all crema marfil with a glass border in the shower. When you step out of the shower there is a mosaic of the same material. Please see the photos.

I was thinking of putting a border of the same glass tile border that is in the shower with a pencil edge all around the mirror. Will this be too much?
