Installing electronics in wall cavity - Regulations?

[Fredde87]

Due to the amount of light that is typically in a bathroom, how well would you be able to see the screen through the batter-lit 2 way mirror?

The mirror I am buying is specifically made to be used as a mirror TV. It is of a brand called MirroView. It comes in two versions depending on how bright the room is, the manufacture recommends the normal version for a bathroom.

I will receive two 5x5cm samples before hand to test both before ordering the mirror itself.

Wouldn’t it be cheaper and easier just to watch TV sat on a sofa like most other folk?
