I'm about to fit a seperate "bar type" thermostatic shower over the bath and the wall where it will be mounted is a stud partition.

The feed pipes will need to run inside the stud wall either up into the loft space or possibly down to the under bath area.

I guess I will have to remove an area of plasterboard, fit the pipework and then somehow replace the plasterboard (with Aquapanel?) and finally tile.

I'm keen to minimise the amount of plasterboard I remove and am not really certain how to join the new plasterboard as it's unlikely I will be able to cut exactly over the joists / noggins, especially if the pipes end up going downwards and therefore have to go behind the end of the bath.

Any suggestions / advice before I start?

Not sure if this is the "recommended" method, but it is the one I use....
Cut out the plasterboard you need to. do the plumbing etc.....and add any wood needed to anchor your shower and so on (this is not as easy as it seems, the only bar type mixers I have fitted seemed to have no real method of securing other than the feed pipes, but I suspect that has changed?)
If you have your hjoin on a stud, that is good. If not, use a length of 1" apprx wood, offcuts etc, doesn't matter. Screw to the existing plasterboard (behind the face!), and then you have fixings for the new bits. simple. If a long section, may be bettre to keep it as a single length of wood rather tahn small bits, even 2" thick?? but I have used this method loads of times for repairs.
I have also used 12mm exterior ply rather than plasterboard in wet areas, nice and strong, and doesn't disintegrate when it gets wet. Aquapanel is good too, but b*****dy heavy. None of it is cheap anymore either

Why not fit the aquapanel over the existing plaster board, up to the shower screen wall fitting?

As above ,

BUT

Connect it all up an turn the water on (but but not the shower) and check for leakes, before you cover it all back up !

Watched a customer do this 4 times before he had stopped all leaks !

I use a PL8 mounting bracket as the ones supplied are poo. Cost about £18 but saves loads of time and stress. Idealy replace plasterboard with aquapanel. Cut out a section where shower is to go mount PL8 on a wooden batten and fit nogigns to existing studs and replace plsterboard or use 12mm ply. Job done. Alternatively get a man in. We need the work.

you can find studwork easily with a thin drill bit, and the holes left are easily filled if you need.

If you can, just bend copper so there are no hidden joins.

Any idea who stocks the PL8 mounting.

It looks just what I need but as I really need it for Monday ordering on-line isn't really on and I could do with a local stockist. (Ideally around Maidstone)
