Homelux or similar is fixed using tile adhesive, you then tile over the matting.

Your layers are adhesive, matting, adhesive, tiles.

Thanks for that.

As other posters have said, you do not want to use ordinary plasterboard in a wet area. Use Hardibacker, Knauf Aquapanel, or Glasroc Tilebacker.

Can't give you any technical details, but we were using quite heavy tiles on our bathroom walls and our tiler used marmox board to line the walls.

Don't waste time and money with hardibacker

Standard plasterboard with either a roll of Homelux water proof matting or mapeigum with corner joint tape

Homelux is the superior option , we have well over 100 wetrooms with this system , many 4 flights up and not a failure yet

Hardi has silica in it , you'd need good masks to ensure the risk is low . You then have to bond it to the wall or screw with there washers . It's time consuming and expensive and those that think this is the superior option need to give there head a shake ! You still need to seal the board edges to ensure its 100% watertight

I'm not sure how using Hardibacker is a waste of time or money, twice the amount of work & addy to use homelux, you don't have to bond it to the wall & standard plasterboard screws can be used & it doesn't have to be sealed before tiling, the only reason I'm shaking my head is why the OP would want to spend more money than needed on homelux

Plasterboard and tanking is still cheaper than hardi

The Posters bathroom has an outside wall , it would need to be bonded to the brickwork and not screwed to timber stud

The boards still need to be taped and filled to seal

Hardi is for those that overboard everything , attaching yet more weight to poor substrates

Homelux won't fail , it's a superior option without a silly price tag

I can see nothing about an outside wall in the OP & if it was why dry line then plaster, I've never taped Hardibacker, homelux might be a good option for a wet room floor & I wouldn't disagree as it needs to be completely waterproof but this post is more about the wall not falling to pieces behind the tiles, homelux might be a very good product I just think it's more work than the project warrants

The length of the bath and the head end of the bath has stud walls.

The foot end of the bath has a brick wall (which is an external wall) with a plastered finish. For this brick wall I had intended to paint it with Dulux Bathroom paint and not tile it.

Andyhop probably is aware of the external wall from an earlier thread.

Hardi is 1.08sqm for £13 trade

Plasterboard is 2.88 sqm per sheet £5

Add half a bag of cement based trade adhesive per 5sqm Weber, Mapei etc £7

5sqm Homelux wall tanking £38

Superior product for similar cost £11 ish sqm

You also won't need a throw away P2 dust mask, silica causes cancer ,you won't blunt your tools cutting it

Hardibacker has its uses , I use it to face wall hung geberit WC frames prior to tiling but that's about it

You don't plaster PB prior to tiling, your just reducing the weight limit from 32kg psqm to 20kg.

I never said you skim the pb before tiling, to fix homelux you fix it to the wall with addy then homelux then more addy & then tiles, so it's twice as much work, £7 for half a bag of addy wow you use some crap stuff I use Nicobond not the B&Q rubbish, I'm not sure where you are getting your info from with regard to a P3 mask unless you are thinking about a totally different product ?

Nicobond is hardly a premier product,

I can buy Mapei Keraquick or Weber SPF rapid for £14 a bag at CTD/ Tile Giant

Hardi contains silica, silica is well known to cause cancer. You can buy a scoring knife but it's as much good as your advice . Every screw you put in creates dust, every hole drilled creates dust.
