New shower room

[Jameswren]

I’m planning the installation of a shower room and am after some advice on the best wall structure – the main factor is overall quality and to avoid future problems related to moisture. space is a bit limited but I can work around it if it improves the structure significantly.

The plan is to have tiled walls, on three sides, then a glass door at the front.

The two existing walls are plastered brickwork and I need to create the third wall. I plan to make this from timber and clad with plasterboard, skim it, apply a tanking solution (unsure what product), then tile. Is this advisable? Or am I better to use something different to plasterboard?

How about the existing plastered walls? Should I tile apply the tanking solution straight onto the painted plaster work then tile? Or should I over clad then tank, then tile?

Any advice appreciated.

Use a tile backer i.e. aqua-board or similar.

Instead of plasterboard for the new stud wall?

How about the existing walls?

Plastered walls should not have a problem of 'breaking down' like plaster-boarded walls.

Are the plastered walls in good condition?

Well, I was trying to save complexity by skipping the part that one of the existing walls isn't really a wall yet because I need to brick-up a doorway and window. They'll need to be bonded then skimmed and tanked, I guess.

The one existing wall is in decent condition although it has a radiator on it and a light switch so is going to take a fair bit of damage/repairs as well.
