DIY wetroom

tom1ie

Hi all
I’ll shortly be starting my wet room project upstairs on a concrete floor in my house. Has anyone any experience with doing this?
I’m thinking of putting in a 900x1500x20 wet room shower tray that you can tile on.
I’m also thinking of raising the floor level so that is flush with the tray using 20mm thick cement board that can be tiled on.
Can anyone recommend a supplier for these materials?
I’ve come across a website called wet rooms online.ie. Has anyone any dealings with them?
Also in the room I’ll be putting the wet room into there’s a crack in the ceiling running the length of the room, approx 4m, which was caused by the joist it was screwed to, not resting on a lintel. Should I just skim over the crack or should I take down the ceiling and replace it with cement board ceiling as that’s moisture proof? It’ll probably take about 5, 4x2 slabs to do as there’s a large value vault in the ceiling.
Thanks all!

All your plans sound ok so far.

You will have to give consideration to the drainage, type size depth, it has to match your tray.

I would use water-resistant plasterboard on the walls of the shower area and then you will need to use some tanking (paint) around the walls up to i think 400mm from floor level. This is also to be painted on the shower tray. (the kits usually come with corner pieces and edging then you paint over the whole lot.

as for the rest of the floor raising is a nice touch but not vital as you have a tray area. I assume you will want to put in some form of screen. most people do as water gets everywhere across the bathroom (sounds fine when on holidays where it evaporates quickly but not really in ireland) would advocate a screen.

and the ceiling, just skim it. no need to tear it out. You will need to put in proper ventilation for the room thats for the moisture.

Yeah so I’ll be installing an extractor fan in the shower area.
I’ll be putting in a 1m glass screen.
I’m thinking of electric underfloor heating, I seen it available on that website for approx 600.
I’m putting up tile backer board 6mm onto the insulated plasterboard, (which I put up 5 years ago when the room was still a bedroom), around the shower area of the room.
With the 6mm board should I stick it to the insulated plasterboard, (bonding compound) or should I use long mushroom fixtures to attach it to the solid wall behind the insulated plasterboard?
The drain is 85mm deep so I’ll have to chisel that out of the slab and then backfill with sand and cement.
For fixing the wet room tray to the concrete floor do I use sand and cement mixture or flexible tile adhesive and what depth of adhesive is needed?
I have a tanking kit also.
Thanks for all the help/advice.

We had a wetroom put in upstairs a few years ago....had to rip it out as it caused issues and eventually leaked into kitchen below
Few plumbers that came out afterwards said that it shouldn't have been put in as there are risks of them leaking over a standard installation
We replaced it with one of these

Much better now

There is a feeling of solidness with the tray, its really slimline, strong and brightens up the room due to the white finish

The cost of the wetroom former was ridiculously expensive, as far as I remember it was about €400 and in the end it had to be dumped

The shower tray was less than half the price and its doing the job

A wet room upstairs and I'd bet a joist floor.

I'd take a a pass OP as above it will inevitably leak or tiles will begin to lift etc etc..

Has no one read the OP's post, he has a concrete floor. Not timber joists as in the case of the person who had to pull it out.
