Hi,

I am about to build a stud wall about 900mm wide along the back of a
bedroom to make room for a shower and basin.
I will be using marine ply or Aqua Panel around the shower area but want
the remainder of the wall to be fitted with plasterboard.

How do I join the two together so that there is no ridges?
(I am intending tiling along the wall about 1 metre high)

I was intending using 12.5mm plasterboard so I had hoped to find 12.5mm
thick ply.

Any advice appreciated before I pick up my tools!

Thanks

If you have a look at the Knauf website there is loads of useful info as I am
doing something similar .What it says is to take the Aquapanel to just before
where the tiles stop and continue the rest with plasterboard so that when the
tiles are up the edge( and therefore the join) of the Aquapanel is hidden .
Aquapanel is the same thickness as plasterboard 12.5mm .

This is -maybe- a little light to tile to.

If it was me.
I'd use 18mm ply, and 5mm shims behind the plasterboard, along the
studwork.
However.
If you want the tiles and plasterboard at the same level, you'll
obviously need a bigger offset.

I have just tried to remove some tiles from a false wall covered in ply that was
much thinner than 12.5mm and trust me they were well stuck and the wall was
solid as a rock .I did make the battens fairly close together tho .I don't
recall excatly what I did to the ply but I think I just primed it then tiled .

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Ian Stirling
<ro...@mauve.demon.co.uk> saying something like:

No, it's perfectly fine.

If you are tiling over the join, don't worry..use 15mm ply and
plasterboard both...

If you want a painted finish, you are in a bit of a puzzle, I would
recomend leaving a slight gap and filling it with decorators caulk
carefully smoothed flat and using lining paper to cover the join, or
better still scrim tape and skim plaster the whole lot.

It isn't, if supported at regulation 400mm studs with sensible noggins
as well.

I see no pint in actually using ply on vertical surfaces where water
will not collect, except for structural reasons.

Thanks for all your replies, Kauf did have some good info, I just need
to decide if the Aquapanel is worth the extra cost over marine plywood.

As I suggested before about Aquapanel/Plasterboard joins .If using
Ply/Plasterboard then take the tiles to just over the join then you do not have
that problem .
