Hi all,

A mate has roped me into helping him hang a 1400 x 900 mirror on the
wall in his freshly re-furbished bathroom. It has been re-tiled and
from a knuckle_knock, sounds hollow so I don't really know (pre any
further tests) what's behind there (studwork, dot_n_dab plasterboard
etc).

The mirror is to be mounted landscape and has a wood backing, into
which the supplier of the mirror has attached 3 small hanging 'loops'
at the back near the top (but still behind the mirror) and a couple of
little brass retaining plates that are exposed underneath. The idea
being that you hang the mirror from the top and retain it there (so it
can't be lifted up and off) at the bottom.

There are several issues:

I'm not sure I like the idea of trying to provide *three* hanging
points? They only have to be slightly out of line and the whole thing
could rock about on two and if and / or the middle wall mount was
lower it would not do anything at all?

It's common for mirrors etc to have three hanging points so they can be
hung landscape or portrait. Only 2 are used depending on the orientation.

I'm not sure I like the idea of trying to 'hang' something so big and
heavy on loops that can swing about. They might be ok once you have
them hooked over whatever? but as you won't be able to see them
while you are doing it ... ?

That's always a bugger, you can't see the screw. Best done by
feel/trial & error. Two man job.

I really don't want to be party to either me dropping or it falling
down onto his new basins and unit (or any of us)!

Once hung the load is only downwards. As long as the fixings are decent
even very heavy mirrors will be fine.

So, assuming we have checked the wall behind the tiles for services
etc ... can anyone recommend hardware that would make this job easier
or more predictable please? Are there any brackets, clips, mounts /
whatever that would give us a better chance of a getting a good
anchorage on(?) / though the tiles and would also attach to the wooden
rear of the mirror (looked like 12mm chipboard to me at a quick
glance) and give the whole thing a more positive (and ideally,
adjustable to some degree) location?

I have wall hung heavy plasma TV's and the like but never on tiles and
where you couldn't get to the back of the thing as you were mounting
it.
