I am trying to understand exactly where the mirror goes. The bathroom is not the problem, but the washer and dryer are? I am not sure how to get a mirror behind the headboard. The mirror is long and maybe 2 feet wide. I would have to get it to stick to the back of the headboard to accomplish what I think you are suggesting. Not sure how to do that.

If the track lights aren't on, and the ceiling fan isn't on, is it still a problem?

The electrical box is on the other side of the wall from my head and 3-4 feet higher.

Thank you.
