Vanity unit in main bath room - again nearly finished. I am yet to install a mirror but why I would ever want to look at myself - I don't know....
I also don't want to have a mirror above the basin! I have a plan to have the basin under the window, and a slim wall cupboard on the wall next to the window at about head height, with the inside of the door being a mirror. The idea is that when I want a mirror, I can just swing the door around. I am not sure however how well the lighting would turn out, with the light coming in from outside through the window behind the mirror. Perhaps you could try something similar, and without the lighting issues luckily...
