Hi,

We have been living in our house for 7 years, and have had a persistent problem with the shower in our en-suite leaking, to such a point we stopped using it 2 years ago...

The property was new when we bought it and Persimmon the 'builder' failed to fix the leak long term despite multiple attempts.

Today I plucked up the courage/effort to start taking it out. Didn't take long to find out what was wrong - there were tiles missing! - at the point the screen passes over the freeze on some of the tiles, they had simply left them out to avoid the standoff, well it would have taken 10mins to do the right thing?!

Anyhow, all tiles are now off, and I can see the state of the plasterboard behind which I need to replace. I intend replacing this with moisture resistant PB, tanking and re-tiling with products recommended on here.

My question is with regard to the position of the tray - it currently sits against the studding, with the PB above the tray, should I leave it like this or pull the tray out so that the PB goes behind?

Any other tips gratefully recieved!

Greg

Greggs - Love your cornish pasties!

As you are at that strip out stage it would be better to remove all the plasterboard and fit Wedi/similar to the walls.
If you have a square area for the tray move it out slide the NEW Wedi board down the side and complete silicone seal the tray in.
Make sure you seal /tape all the corners and joints.

Timeless John.

as above

had you not thought of informing NHBC i take it its a new build so should have 10year guarantee.
saves you time and money?

thanks for the comments.

NHBC worth slightly less than the paperwork you get... several others on our estate have been down that road (and back again!) with much more serious issues. Might have some use if the house were to fall down!

John - is the Wedi necessary if I am tanking as well?

have you informed your insurance co. or even get the the TTA involved.sounds like you have some form of case ..i only say this because are you going to be doing the job on yourself?

No I haven't, in all honesty I'm more interested in just getting it sorted - have been through the angry bit a few years ago!

Some of the storys I've heard, about as much use as an ashtray on a motorbike

Use Wedi (or similar) and you don't need to tank .

Hi, if the shower tray has any upstands then you need to cut the tray into the walls to enable the tile to sit correctly over the upstand. (or fit the tray then board upto the upstands)
If the tray doesn't have upstands then I would board the entire enclosure with your chosen backer board then fit the tray up to the board , ensuring that it is level and that you have applied silicone on all edges that meet the walls.

Hope this helps

No upstands, so not really sure why they have recessed it under the PB. I've read on here that there is a difference between different boards (waterproof/repellant), i guess that if I am to go without tanking I'd need a water repellant board? What are the options for this - the easily available one (Aquapanel from Wickes) I've read is only waterproof so wouldn't act as a membrane, and other tips gratefully recieved.

Greg

They would have recessed the tray under the plasterboard to get a better seal for the tiles onto the tray - however if you have a wooden floor you may find there is going to be some movement and the seal will be broken!
Wedi or aqua board will be suitable for the 'new' walls and waterproof is all you require.

Timeless John.

Can you post a pic of the tray.....before we let you pull it forward..?

Pics of tray hopefully attached - and the craftsmanship that led to the problem...

Taking advise to use a board product, can anybody advise how to join aquapanel to PB mid-wall?.

Should add, floor is chipboard.

They left that piece of boarder out to save scribing to fit..

The tray can come forward if need be and tank the walls before fitting the tray back...

You will need to remove all the old silicone because the screen will not sit back on the same place once you pull it foward...

Also if you pull it forward you will need a new tray plinth.....

Thanks Dave

I am a little unclear whether to go the green PB with tanking or the Aquapanel route... if I need to tank anyway (which I can understand why around the tray/wall interface) then there seems little point in going for the expense aquapanel?

Thanks for the hints WRT to pulling it forward.

Greg

Just use PB and tank it....no need to be green PB either..., make sure you tape the corners and slightly onto the tray to prevent ingression.

I actualy prefer to use tanking membranes like the one from wetdecs...

Here's a video of how to install it.

hi looks like in pic 2 your leak was between shower tray and tiles .aqua panel should go behind all tiled area to get flush you need to pack out studs id leave tray recessed and make sure it is sealed between aqua panel and tray and silicone bottom edge of tiles to tray and internal corners of shower might pay to lift carrpet to see if any damage reco you should tile underlay w/p and tile floor (chipboard doesnt like water at all )
