New build wet room

[PRT]

Hi All,
I need to make a wet room with alcoves for my clients. It is on the ground floor with UFH in the screed. I have left the shower area of the screed out so I can create fall to the drain which is a 100mm pop up at this stage.
The shower is enclosed on 3 sides by timber walls, 2 internal and 1 external. It is 1200mm by 1350mm with the drain in approx the centre. I am lining the walls with cement board.
Am I best to form the floor with sand/ cement or use a pre formed tray? If sand cement what fall should I put in?
What tanking system would be best for this application?
How far past the edge of the shower should the tanking be?
What sort of adhesives , grout , silicones are best?
I live on an island off the west coast of Scotland and there is no one locally I trust to do this job.
Any help is much appreciated.

hi your best bet is to contact wet deck or just pm him sort out your tanking or waterproofing and then get the appropriate adh and grouts to suit hope this helps:8:

hi...i find schluters kerdi or durals wp membrane the best tanking system along with mapei adhesive grouts and silicones....not the cheapest but very good products

Thanks Stu

Tilux and Impey is just as good as Schluter and is definitely cheaper IMO.

Thanks Dan, I will check all these out.

Definately agree Stu, great system you've specified there

How thick is the screed where you have left out for the tray PRT?

I'm on an island off the North coast of Scotland or I would have done it for you mate:smilewinkgrin:

Hi Merlecollins, The screed is 75mm thick.
Another question, A guy has suggested tanking it with fibreglass.(he is great at telling people what you should be doing) I am not keen to do this because no one else has suggested it, nor have I seen it recommended anywhere. Do tiles stick to it? I wouldn't do it anyway, will definitely go with a tried and tested system.

Hi Merlecollins, The screed is 75mm thick.

Smashing - you've got plenty height to install a preformed tray, which, if skills are thin on the ground where you are, will be your best and easiest bet

I would definately give the fibre glass a miss, although I have fixed to it in the past, and opt for a product like the Schluter that Stu mentioned or Dan's Impey product

What tiles are you fixing to the wetroom?

 

[PRT]

Tiles are yet to be chosen by clients, are non slip better for the floor?

I would guide them towards mosaic (not glass mosaic) for the floor, possibly stone mosaic - the joints will act as an antislip finish and you'll be able to tile your falls without enveloping larger tiles

Thats a greta idea for the floor, thank you.

This is the sort of thing I mean
