Ensuite Bathroom overhaul

[splashthecash]

Hi all,

First post to this site - some great tips/advice from what I see.

We are going to do up our jack and jill bathroom and planning on doing it myself. There are tiles on the wall from ground to halfway up the wall on all sides (within the shower obviously the tiles go all the way up). I have all the floor tiles up and and all the wall tiles off. I think I may be able to get away with just replacing the plasterboard in the area where the shower was as this was particularly hard to get wall tiles off of.

So at the moment I am cutting the down the plasterboard at the point where the shower enclosure ended.

Three questions.

1) Is this okay to do or should it be all or nothing in terms of new plasterboard?
2) Assuming it is okay, what would I fill the gaps with between the existing wall and the new plasterboard? I ask because I would be worried about making the cut plasterboard damp because I will have cut that and the chalk bit will be exposed. If simple filler or mixed up plaster is fine and wouldn't introduce moisture\damp then happy days. Or perhaps I just leave it unfilled and be sure not to lay any tile adhesive around that particular gap?
3) Because I will be leaving the existing wall and putting new plasterboard beside it, there is going to be a small difference in depth because the existing wall would have been plastered and rather than plastering the new plasterboard I am just planning on putting a bit extra tile adhesive on the new plasterboard to make up for this difference. Does this make sense and is it the best way to go?

*Note, I will be tanking the new plasterboard before tiling over it.

How about pics of the whole bathroom so that i can understand what i'm looking at?

The ones above show the area to which I'm asking about - i.e. the shower corner where I am starting to remove the plasterboard.

However if you feel other pics are needed...

1) That's ok, just replace the damaged bits.
2) Filler or plaster is ok, it won't affect the cut end. Use a bit of scrim tape as well to help stop any movement.
3) Sounds like a plan.

You're better off not plastering plasterboard that is to be tiled as un-plastered it can hold more weight of tile. Without looking at the manufacturers website I think plastered 25kg per square meter, and 35kg bare.

Any small gaps can be filled with expanding foam, and the bare edge of plasterboard doesn't matter because you say you're tanking.

I would fill any gaps with a hard filler, plasterboard adhesive will do if you have some. Then follow the tanking manufacturers instructions and tank away.

Thanks to you both!
