Newly tiled shower/bath is leaking

your on the money whitebeam all yours:8:

Yes mate, it's so if any water reachs the back of the wall this situation is avoided

I understand the logic but seems rather difficult to do in practice especially if the walls aren't so straight and the edge of the bath is curved. If the tiles are 10mm, you don't have much room to lip onto the bath.

Also, tiler did Silicon the joint between bath and wall before tiling.

Is sealing the grout doing to help prevent water getting through?

Where the bath edge touchs the wall a channel could've been cut out so that the bath sits up against the brick/blockwork. I take it that you cannot see the curve of the bath where the tiles are, 10mm is a good thickness. If you wanted to tank to the bath edge this would'nt be difficult. Mark the bath with a pencil line where the tiles touch the edge after removing any Silicon, remove lower tiles, use some masking tape onto the edge of the bath where the pencil line is, apply your wet tanking system and lay the tape but don't leave a dip between the wall and bath edge and use more of the rubber solution. When dry fix tiles, your tile fixer should have known this concerning the bath edge.

to me it sounds like the shower head is leaking or the mixer valve and is taking its time to get down the wall really sorry mate thats no fun at all so if the shower shoots into the center of the tub there is no leaking at all? didn't mean for it to rhyme or repeat

That's right. If the shower is aimed into the middle of the bath, no leaks. So it's definitely not the mixer.

I need to find a solution though. Only thing I can think of it to seal the grout.

hi whitebeam has given you good advise your bath should be recesed and w/p run down onto bath as stated you shouldnt Silicon directly on to w/p best to use mastic and run w/p over read post again thanks :8:

Hi all, just reading the comments on this post and viewing the photos and all i can suggest is, in the photo under the bath it looks like there is water dripping down the hep20/polypipe feeding the mixer valve. small drip dwon pipe.
Are you sure if you only run the shower in the bath for 5 mins it doesnt leak.
Did you Silicon the bath to the wall as it doesnt look like there is any boarding behind the tap end of bath(did you board upto top of bath) not best practice in my view.

Is the vertical joint in corner of bath siliconed.?
Still keep persevering and all will become clear im sure.

When you say you shouldnt Silicon upto w/p what do you mean.?
Do you mean you shouldnt use sanitary Silicon to stick the bath to the tanking.???

When i put baths in i Silicon all edges to be fixed, batten underneath, Silicon top of batten, stick bath in, Silicon again around bath edges being careful not to leave it raised to hamper tiling, Then final Silicon bead applied neatly with my fugenboy.

Good Luck

hi Gazebo realy depends on w/p but best practice is as whitebeam said rec bath and bring w/p down and onto bath as described to make w/p enclosure complete yes bath is siliconed in but best to use compatable product (mastic Silicon) depends on w/p is compatable with norm mastic and tape over to top edge of bath making a complete w/proofing not a bit of this and that :8:

Sorry but taking out the bath and chiseling out the plaster is not an option at this stage. Also, the bath has a lip all the way round and doing so would lose the lip on a couple sides meaning the gap between tiles and bath would be different.

The 'drip' you can see on the pipe is actually hanging off the Silicon blob in front of the pipe, it's Silicon. I can clearly see where the drips are coming from and it's not the mixer.

The bath is Silicon to the wall, just so happens at that end of the bath the plasterboard is cut off at the edge of the bath so I could access pipework.

The vertical joint in the corner is NOT siliconed, I will do this and hopefully cure the leak in the corner.

BUT I still need to figure out how to stop the leak in the middle. Like I said, it's not possible for me to remove the bath an chisel out plaster. There must be a less destructive answer? No one has commented on grout sealing?

Afternoon bill...

How soon did you use the shower after the tiler finished grouting..?

Probably 2 weeks or more.

RE. grout sealing I feel this will be only a temporary fix, if at all. It seems that the Silicon joint between wall and bath has failed somewhere, It seems to me you should remove the bottom row of tiles and reseal this(I sometimes use Silicon called CT1, expensive but good, will stick to damp surfaces), or you could tank over edge of bath as described earlier,

 

[DHTiling]

Right bill...Something for you to try....

Cover the wall in clingfilm but do not cover where the Silicon is....then direct the shower onto the wall and see whats happens...the cling film will keep the wall dry but still let water run over the bottom where the tiles meet the bath...

If no leak then water is getting in through the joints as you thought...

If water is getting in through a joint as quick as you say then there is a problem with the grouting and this needs redoing...

I think it is more than likely a very thin hairline split in the Silicon where the Silicon has not adhered properly...

try this and then come back..

you know it really surprises me on how much water has come through I think dan is right excessive water on the ledge of the bath and working its way under the wall.a trick I learned a long time ago is rub your Silicon in both directions to ensure a good bond. mabe the tub has settled a little bit 1/8 of an inch on the back wall is all it takes.
