Warm wall in a wet room

[frogeye]

Hi all
Long time no see - been busy.
Been asked about installing warm wall in a wet room (or normal shower room - not decided yet)
Is this even possible? Is there a kit?
Has anyone done this at a domestic level?
Advice anyone please - or shall I tell her to install one of those Triton ceiling mounted driers?

Are you talking about under tile heating on the walls?

[doug boardley]

that's how I read it too Dom, did you ever do that on the Fitness jobs?

[diamondtiling]

Yes Doug, many times in the aromatherapy suites, its the same as UFH systems but I always used cable instead of mats.

What is the makeup of the walls frogeye? or will you be building the wetroom from scratch?

[Dave Ramsden]

The seating area at ther back of this steam room has cabled UFH running all the way to the ceiling.... mmm warm bum

[diamondtiling]

Is that a thermostat on the wall Dave, or did you situate it away from the public.

I used to put mine on the roof of the room and set it on a 7 day timer or in a maintenance cupboard.

Undertile heating is great in the situation that Dave has shown but unless the wetroom has a seating area then I cant see the benefit of it. It would be fine under the floor but maybe a bit OTT for the walls.

[frogeye]

Stone me - some quick responses - thanks!
Went and had a cuppa and some toast

Location is upstairs, recently constructed in plasterboard etc. Plaster skimmed too, so couldn't advise there. Floor to wall tiling. I think she must have discovered this at a swimming baths...
But if you say it's possible, is it a use of the under floor stuff (warmtile?) to same electrical installations? Does it have to be a separate installation to the floor, although funnily enough she didn't mention the floor. Can one mat sweep up floor to wall?
Is there a requirement to 'indicate' that a wall is heated? As in a border? to deter drilling and fitting shelves etc or do we hope the owner uses some common sense?

many thanks

Straight onto plasterboard??? Might be worth while investing in something thermal!

Im not sure about indicating the area is heated, might be worth delving a bit deeper there. If the floor is UFH it might be worth while using a seperate mat and controller...

[diamondtiling]

I would be using cable instead of mats and fixing it in nice neat straight lines with a glue gun. The floor heating would be separate to the walls and it would not be fixed to plasterboard. You need to install heavy duty tanking to the boards for a 100% leakproof room, your cables would be fixed to the tanking.
As for drilling holes etc you and your customer need to sit down and plan the room from scratch and incorporate all ideas into the building process. All holes should be plugged and sealed with silicone so that the tanking is not compromised.
Plan it right now and you will be fine.

Just a last question, have you installed a wetroom before?

[frogeye]

Must be honest - no.
If I do it I will be relying on information over experience. or maybe a

[diamondtiling]

Getting the installation right is crucial, these rooms are a luxury item and expensive to build. Your customer may want multiple shower heads fitted and that all needs good planning. If you are unsure why not get help from a member that is experienced and is near to you, at least then you still get the job and learn how its all brought together.

The man has a point...

[Dave]

Frogeye you little scrotum, how are we.. hope the health is ok since you stopped tiling..

[frogeye]

You can't keep a good man down.
Health is fine ta
No more cutting tiles in enclosed spaces is the answer.

A bit familiar aren't we - have we been introduced?

Will be doing the job, but no warm wall and a shower tray has been fitted, so no wet room problems.
But few more questions please.....

One wall out of square by 10 - 15 mm (or near enough) can I use a bag of fast set floor adhesive (from last job at brothers) for a tapered skim? (trying to keep costs down)
The Bal wp tanking kit I was hoping to use has gone off (shelf life?) so is the Ardex stuff better?
6mm ext ply over a chipboard floor? Prefer not to but better?
Tiling a sloping area that will get wet - tank and fit as normal - 8 x 6 tiles - or would be better using mosaic sheets or what?
Many thanks
Off to prime walls soon

[diamondtiling]

6mm is no good for overlaying.

Ardex or bal? no competition there at all.........Ardex.

[Daz]

I agree with Diamond. Ardex is better than the Bal, but a membrane tanking is even better than a paint on IMO.

Use 6mm cement boards (like Hardie Backers) glued and screwed instead of the ply provided there is no floor deflection.

[frogeye]

Thanks for replies.
Ardex it is,
don't know where I got the 6mm ply idea from - hardibaker then
what about the fast set floor adhesive as a skim on a small area? need to know soonish as hoping to do tomorrow - thanks
And the sloping wall tiling ?

frogeye - now trying to remove the Bal primer from his hands

[frogeye]

used the floor adhesive to make up the uneven wall - doesn't work as well as plaster but with perseverance got the job done.
As for sloping wall - I will just tank it and hope for the best. Might have to use a bit of rapid set on this bit though?

cheers

Don't forget the pics..

[frogeye]

Don't forget the pics..

You wouldn't want pics from an amateur Dave!

[Dave]

You wouldn't want pics from an amateur Dave!

OH!! Yes we would.. just not wivers amateur pics..

[frogeye]

Okay - mostly done and almost ready for floor
6mm hardibaker bought but ctd had no screws - can I use ordinary dry wall screws? They are coated.

I have made every amateur mistake possible, but at the end of the day that is all i am.
One 4 week course a tiler doesn't make. respect to all those who have succeeded though.

Thanks again for some real good advice.

[frogeye]

Wot no replies?
Still need info on those screws please.

[diamondtiling]

You can get the screws from B and Spew, I would advise using the correct screws just incase, at least then you are covered.

cheers pal
off to buy now
jewsons suggested standard dry wall but I wasn't sure

Open a trade account while you are in B&Q, you will get them a bit cheaper, just take some ID with you.

[frogeye]

Not trade anymore - still have my other cards though
thanks for the thought anyway
