Ever wished you could have a mirror directly on your shower or bathtub wall? Fog makes it a bad idea, doesn’t it? Not with this one! You just have to fill the back of the mirror with hot water to equalize the temperature as well as prevent fog and condensation. With cups that attach securely to tile, glass as well as other smooth and non-porous surfaces, it is very safe too. This mirror is even equipped with a convenient hook to keep razors or washcloths close at hand. A must!
