The mirror is the only reason I redid the bathroom at the point that I did, It runs a version of Magic Mirror running on a rasberry Pi, I built this with an old monitor I had around the house and a two way mirror.
Now onto the build,
The bathroom was in decent shape and not much to it, just a vanity and toilet really. After building the mirror I removed the vanity ran some new electric to behind the mirror (GFCI outlet don't worry) I ended up putting a vinyl wallpaper up on the back wall kind of like an accent wall approach all new lighting and new ceiling light installed.
I had to find some flooring to match and got very lucky and matched very well,
