Wet Room

I'm going to put a wet room in the upstairs of my house. I'm just wondering is there anything I need to put in the floor to stop water/moisture seeping downstairs?
 
As far as I know you have to 'tank' the room using a flexible rubber type membrane that goes on the floor and up the walls about 6 inches.
 
I think a company called advanced materials in Naas offer this tanking service.
 
get a highly reputable builder who has considerable proven experience with wet rooms because they are specialist work. If you tender the project select your contractor on service and not price. Otherwise wet rooms are nothing but trouble.
 
Hi dnag,

Be sure to have the "tankers" give you a proper description as to what they actually do, I had one chancer in my house who when this question was put to him seemed to expect a plumber to do most of the work, the quote for his "work", (ie painting some rubber gel onto the floor and walls), was really funny :D , as far as I can recall it was over 2 grand for a 4 foot by 4 foot shower area.

ALERT.
 
Folks,
If you have a wet room on the groung floor (tiles on concrete) is tanking required of is it ok jus to tile the complete room??
 
As someone who experienced many problems (and thus much expense) with an upstairs wet room I'd advise you to think again.
It was the two rooms below that became wet- and two repairs and two re-decorations later the damage is still visible. We have certainly asked ourselves if a wet room (an upstairs one) could ever have been worth it.
 
You really need professional advice on this. We planned to put in a wet room upstairs as well but following advice from two different plumbers we realised it wouldn't work. This was due to problems with the water drainage and the position of the pipes under the bathroom floor.
 
Whackin,

its basically an open plan shower area with fully tiled walls and a floor which falls to a central point for waste. No doors or screens or trays .
 
Installing a wet room at the moment, and looking for affordable non slip floor tiles for the area. Does any one have anyrecommendations as to brands and where to buy them.
We were looking at the Fired Earth mosaic range, but very expensive.
 
Have a look at this product, wedi boards for wet rooms, there's a supplier in Navan

we're getting this done at the moment (unfortunately we're in france so i can't recommend anyone for you) but the original quote from the builder for the whole bathroom didn't change when we decided to go for an 'italian' shower (same black membrane under tiles you're talking about). He said the price of the membrane was more or less the same as the price of a shower tray.
 
hi HurlingFan,

Did Advanced Wetrooms do everything or did you have to get a plumber yourselves?

ALERT.
 
I also spoke to Advance Wetrooms and they only do the tanking and slope and install drain. They offered me a 5 year guarantee though - so if I follow it up I'll defo have to get the extra 5 years added on! They quoted me 1900 +VAT for the tanking. They require you to have a plumber/builder to plumb drain and gut the room (we're doing a renovation), and then a tiler for tiling afterwards. I would be very interested in hearing from someone who used them and a review of their work. (Hurling Fan?!)
 
Hi Nadeise

We're in our house since last November and used Advanced Wetrooms in the ensuite in the Master bedroom. Haven't had any problems with it so far and their service was efficient. Like other posters my plumber was very nervous about putting a wet room upstairs and recommended that it be done properly. It cost about the same as your quote and again it only included the tanking and sloping and the drain. Must say delighted to have a wet room and this bathroom looks fab! I did have to chase them a bit (several phone calls) for a receipt saying that I had paid and it was guaranteed for 10 ten years. A five year quarantee wasn't mentioned - wonder why this has changed? Although I was just musing the other day if the company goes out of business (like some housing related companies are at the moment) a 10 year quarantee isn't worth much is it??? No connection to this company.
 
Hi folks,

This might be of interest to anyone considering a wetroom upstairs in their house.

We've just had one installed, and its gone very well. We spoke to Advanced Wetrooms, but found their quote a bit high, and we were worried about the guarantee they offered - if there was a leak, would they just repair the tanking, leaving us to foot the bill for the re-tiling afterwards?

In the end we went with Donabate Bathrooms and Heating www.dbh.ie - they handled it all from start to finish, did the plumbing, tanking, tiling, electrics etc.
- Very good quality of work, and and they left the house spotless each evening.
- They've done a lot of wetroom installs, and we were able to go and look at one of their past jobs before we decided to go with them.
- They also have a very good showroom in Donabate with lots of gear on display (very helpful when you're trying to pick out the stuff).

The clincher for us was that we could hand the job over to them, and not have to worry about organising all the different trades to come in individually, and they'd get all the details right for doing the wetroom properly (for example getting the tiling levels right to meet the floor drain properly). We had a few tricky aspects to our job, but they were handled no problem.

No connection with them, just very impressed by the job they did!
 
You've had plenty of advice about good installers OP, but the best advice was keeping it downstairs.
However, if you insist on putting a wet room upstairs...

Consider the interface between the wet room and the rest of the house.
Its very difficult to dress in a wet room - its wet!
You have to dress elsewhere usually.
What protects the floor covering just outside the wet room?

You should also consider how to deal with the moist air generated by a wet room so it doesn't migrate around the house.
Evacuation through a heat exchanger is only one part one solution, as is good sealing around the door - perhaps install a glass door with sealed surround, like a sauna.
The real issue is preventing moisture laden air finding its way onto cold surfaces, condensing and causing damp patches and mould.

Also be careful where you site the outlet.
Back in my student days we were nearly run out of an Italian Pensione [small hotel] because one of the lads had fallen asleep after a hard night while taking a restorative shower in the wet room - his butt cheek had blocked the outlet - flooded the whole floor.
This is where wet rooms and showers can fail if they get blocked for some reason - no overflow.

You should consider the foreseeable accident and not site your office with its mission-critical laptop and backup media/external hard drives just below the wet room.

Finally consider your floor - if its timber it may move significantly and any persistent small leaks of condensation will tend to damage the structure through action of damp, rot and fungal attack.
Brace and install Rockwool insulation or similar to reduce the twin risks of movement and condensation respectively.
Also consider installing a suitable substrate to support the tanking and installing vapour checks to all walls and the ceiling to contain the water vapour.

It would be great if people would post their negative experiences to this thread so we could learn what to avoid doing.

FWIW
