I love archways in interior design. Whether it be an arched walkway, or like this bathroom, an arched mirror. The reason is that it gives the impression of being bigger than it is, and this in turn makes the entire space feel bigger. On top of this, it is also very aesthetically pleasing as well. So, with this arched mirror we have a bathroom design element that looks very classy, and at the same time makes the bathroom actually appear bigger than it is. This is because an arched mirror actually helps make the ceiling seem higher. This is a much cheaper option than actually building your ceiling higher.
