Last May when the master bathroom vanity was installed I hung two distinct mirrors on the wall over it: one for me, one for Charlie.
Mine has always been a little low according to my height.
When the 10″-tall backsplash was installed recently the mirrors in their original position hung over the backsplash.
It was an easy task to raise the mirrors about 2 inches. My mirror (the smaller one) just needed to have the hanging wire shortened.
To match the bottoms of the mirrors at the same level I moved the hanging screw up about 3 inches.
Now both mirrors are fully useful to both of us.
We might have to put a curtain of some kind at the window. Maybe to cover the bottom half.
Where can you make a small but practical tweak?
