Doing a small renovation in an old cottage and the clients have asked me is it possible to keep the newly installed shower area in traditional plaster with wetroom floor. Naturally ive always tiled shower areas, and have never came across anyone wanting the shower in a trad plaster wall. Now im wondering can it even be done in oridanry skim coat or is there a more waterproof skim on the market for these areas. Surely the skim would fail somewhere down the line with constant water on it unless theres a better product for this area.

I'd say a big no personally unless the other guys know of anything.

Just remembered about the thread start of year i posted about the water running down the wall and the skim run with it! Its either tile the area or maybe theres a waterproof skimcoat out there for it
 
You don't use any gypsum products in a wetroom shower area exposed to the water.

Where do people get these ideas from.
 
We done a under floor level bath in London last year using cement, marble aggregate and a silicone based product .that was water tight but the structure was block, tanked, scratched, tanked, scratched then topped off. It was water tight.

As for a shower room you might be able to render the walls with waterproof sand cement with a silcone based additive to a spounge finish I'm guessing with a dye In it to get it looking he coulor of plaster but I think it'll fail over time and also will not be worth it

Any wet room ive installed, its been tiled and underneath tile addy, theres this waterprrof membrane rolled onto the walls and also sealed at all joints to make it completely waterprrof! No more ply used on floors.
 
An be done in venetian or micro cement really. Venetian can be made water proof using a product called hydro calce and waxed currently. Micro cement is naturally waterproof on its own. It gets sealed to maintain the colour that is used to tone it. Both could be made to look the same colour as dried multi finish if that's what the customer wanted
