This Transitional -Whimsical bathroom remodel is simplified by the natural stain used for the vanity. Taking the glass backsplash 3 tiles high minimum, helps this bathroom to feel larger. Food for thought; when using any glass tile, thinset must be white. Whatever color goes behind the glass, will show through. Also, keeping a 1/16 grout line increases the visual longevity of a space. Larger grout lines are typically not built for visual longevity, unless used in brick install.
