self-levelling screed for wet room floor?

[DHTiling]

It would be easier to install a channel drain against the wall area...then you only have to slope the floor to the wall , instead of trying to slope it in 4 directions.......

Again a call to wetdecs and tony will sort you with a channel drain...around the same price as a preformed tray..

Here is a drain sytem that works in a similar way...but rather than coner drain it is a straight one but it gives you the idea i mean..

That's a great idea and I hadn't thought of it. The problem I have with the existing drains is that the fall is minimal and extending the pipe any further toward the wall will - I think? - mean that the fall will need to be greater.

The existing floor was raised by the previous bods to give a fall on the drainage because the inside and outside levels are the same. This is an old cottage which had drains (septic tank) installed decades ago. The waste pipe shown hasn't an entirely adequate fall - when emptying the sink, water backs up slightly through the shower and then very slowly drains out.

To get round this and to avoid having new drains and septic tank installed I've found that by raising the pipe as far as it will play - around say 5 mm - improves matters satisfactorily but of course the pipe is then at an angle to any fittings for the shower trap, which means it won't sit flat to the new floor. To compensate, I've bought a Kaskade trap Kaskade Wetroom Shower base System which has a side entry with a movable ball-joint. I dry fitted it today and it seems okay.

I should add, importantly, that the low ceilings here mean there is no room to raise the floor any further, which would be necessary if as I assume, extending the waste pipe would require that it has a steeper angle.

Hope I'm making sense!

You are making sense....you need around a 20% fall to drain..if you can get this with the screeded floor then thats fine...are you using mosaics on the wet floor area..it would make the falls easier to do..?

Yes, I intend to use mosaics. A poster yesterday in reply to another of my queries (maybe it was you!) suggested pebble mosaics, which I rather like the idea of, so I'm currently seeing what's available.

Many thanks for your replies

Pebbles would look nice...( and no not me )..

Come back to this thread if you get stuck or fancy showing us some more pics of it all complete..
