Wet Room (Kind of)

peterc14

The floors are due to be poured in 2 weeks. In the bathrooms I am having a wet area for the shower ie just a shower screen with a floor drain, tie no tray but just tiles as the rest of the bathroom.

Just wondering how people would recommend creating the fall in the shower area?

The screeder suggested that if I marked the are for the shower he would screed this 25mm lower that the rest of the floor so that the tiler can create the fall.

Another person suggested putting no screed in the shower area at this stage and then when installing shower drain etc create the fall with screed to the shower area?

Any thoughts/advice would be appreciated? Would be particularly interested in hearing from any tilers on boards.

Hi Peter,

Are you sure the screed is suitable for a wetroom? Anhydrate(?) screeds aren't as far as I know.

We shuttered them off and left it for the tiler to do, so that he couldn't complain, etc. Put in the drain (knowing the fall was 1:40 to be on the safe side), let the tiler pour the floor, then tanked them, then tile.

Regards,

Fergus.

The screed I will be using is sand cement with fibres... i assumed this would be ok.

Did the tiler use a screed mix to make up the shower floor when he came back to do it? If not what did he use?

Maybe I'm thinking of a different kind of drain, but surely this goes in before the screed?

Yes, the tiler used sand/cement when he poured the shower floors. I had the drains set up at the right level for him and the insulation was in, all he had to do was mix and shape the slope.

The drain is cemented in before the screed but someone suggested just to do this much, then shutter off the shower area with ply to allow the rest of the floors to be screeded... then let the tiler screed the area of the shower to his preferred fall etc into the drain.

Were you happy with result Fergus and and would you recommend I take similar appraoch?

Did you have the drains cemented in at the correct level for him?

I did have the drains set before he started. I took this approach because I had a self-levelling liquid screed where it wasn't suitable for a wetroom, so I was doing the wetroom floors separately (level over most except for the shower area) and it meant that the tiler couldn't complain about how it was done. If your tiler is reasonable it probably makes little enough difference in your case.

I don't see how that make a difference.

If the drain in in place (fixed), and the rest of the screed is in place. The tiler has his start and end points of the fall. So the fall is set. There can't really be any variation of it won't meet up. (unless he reduces the area to fall which is a bad idea.

I'd just lay the screed now to a proper fall. The tiler won't refuce to lay tiles on it.
