I've searched around for the answer to this but haven't found it as yet: is
there any regulation concerning placing a small wall-mounted 12V TV set in a
kitchen?

I have a blank area above a draining board, partly protected from splashes
and steam by a 6" deep shelf which runs the length of that wall. It seems
like the obvious place to mount a smallish TV, say 17" or so. There are
specially-designed water- and steam-proof sets intended for bathrooms but
would one of them be overkill for a kitchen? Is there any reason why I
shouldn't use a conventional set?

Many thanks.
