sorry for my late response. I was quite busy during the last weeks.
@Snowflake: You can completely disassamble the monitor. The connectors are long enough so that I could mount everything on the backside of the wall. It would also be possible to replace the cables and use longer ones I think. Attached a quick shot. Quick an dirty right now
@albertlwj: I don´t know the size of your bathroom. We do not have problems with fog maybe also due to our ventilation system. There is also not much space between wall and mirror so that it is very unlikely that water ever will be a problem.
@bhepler: The tape shouldn´t be a problem (see the comment section in my first post )
