Hello All

Well this could be the most expensive mistake I have ever made!

Just tested my new wetroom and have discovered some watermarks on the
ceiling, they are not really major but over time they will be.

The water mark appears directly underneath where the wetroom wall joins
the floor on the left hand side, funnily enough right adjacent to the
shower trap which is under the floor. I really can't accept that the
water is going through the tiles (pro did the tiling and added all
kinds of waterproof additives) and the membrane which was installed as
per the manafacturers instructions (Tilesure) it certainly looked water
tight if anything could ever look water tight!!!

Anyway my first port of call to try and rectify this is the top access
shower trap. Should I be using silicone in order to get a good seal
between the wetroom floor shower tray and the sealing washer?

(The wetroom floor (aquadec) is a big resin shower tray which has been
installed flush with the flooring it has built in falls)

What surpsies me is the speed of the marks appearing so that's what
makes me think the leak is at the shower trap as opposed to water
penetrating the tiles and the membrane.

Without a waterproof membrane how quickly would you expect water to
penetrate through a mosaic tiled floor which has been tiled according
to all water proofing best practices?

Any help/advice very much appreciated

TIA

Cheers

Yes, I'd suspect that too first.

Yes, use silicone sealant on it. When I insytlled my trap in the shower
it leaked at first using the as supplied washers only. Redoing it with a
bit of sealant as well did the trick

Well what a dummy I am blush. I've Just found an adapter that should
of fitted the waste pipe to the shower trap. On investigation and after
removing some plaster from my ceiling I found that the leak was coming
from where the adapter should of been, basically the waste pipe wasn't
in properly. I Have re-cut pipe and solvent welded the adaptor on and
fitted back together. I also added some silicone for good measure and
we are leak free
Thank god for that, just a bit of patching now.

Thanks Chris

Hope yours is a better job than the wet room my mate ripped out a year or
two ago in a house he purchased. Probably fitted by previous owner. Problems
we-

- Electric underfloor heating had gone open circuit, so room went mouldy
very easily if not careful, though fitting a humidity controlled fan helped.
Window (uPVC) suffered from mould collecting at bottom of glass, very badly
as well.
- When ripped up the floorboards were damp and rotten. Looked like water had
been getting in the gap between wall and floor tiles (maybe), running along
membrane and getting onto floorboards around the shower waste trap (and
other places as well).
- The fixed glass sheet near the shower was always scaling up, some scale
not being removed by descalers.
- Being a wet room the fixtures and fittings suffered. Chrome coming off
towel rail, rusting/corroding fixing screws but most likely as they were
cheap items.
- Water condensing on loo cistern created a puddle around the base of loo
virtually all the time again leading to mould or the thought that the blokes
in the house couldn't aim properly. Really annoying going to loo in socked
feet and getting soaked all the time.
- Damn annoying step up into bathroom to trip you up when rushing to loo
whilst having a bladder emergency.

Anyway all removed, floorboards replaced new suite fitted and all works
fine.

sounds like something I've been having nightmares about for the last
month!

nothing like a good bit of encouragement, thanks

I will let the group know how I get on, I'm sure it will be just fine,
it looks the part anyway!

Just trying to fix the shower flow problems at the minute.

Cheers

I can't understand why anyone would want a toilet in any bath/shower
room, let alone a wet room.

Yeah, in a wet room you don't need a toilet, just a waste disposal unit
in the floor.

A Turkish toilet?
