Help to stop Shower tray leaking

fto

Shower tray keeps leaking.
The problem is the seal between they tray & the tiles.
I have tried replacing the silicon before,but it just fails after time.
I have now removed the shower tray to try & solve the problem.
I think the problem is movement in the shower tray...
Would be grateful of any advice.

Here is a link to what i have uncovered

You need to refit the tray, adjust all the legs and seal the base standing inside it.

You'd be absolutely correct. There is no support for it and until there is it will keep moving and the seal will keep failing.

You need to remove all those horrid broken floorboards (cut them out round the tile boundary) and replace with a piece of 25mm WBP ply screwed direct to joists. Fix noggins if necessary. Then rebed the tray on that. Consider the waste connection whilst you are doing it.

Now if the substrate under the tiles is in the same condition you'll be replacing those too soon. Sorry.

Eh? What legs?

If the tray is glass fibre and is only sitting on the edges it will flex, you will need to support the base of the tray when you refit to prevent the tray flexing.

You have answered your own question. The problem is quite obviously movement in the floor. Those bits of board look rubbish. No wonder that you are getting movement. I suggest that you replace them with a decent piece of water proof ply.

If the tiles go all the way down to floor level, and the tray butts up against them, that's wrong too.

Should have fitted the tray up to the wall, then tiled down so that the tiles are on the lip of the tray, not vertical behind it.

If that's floor tiling, is there anything under it apart from the same kind of floorboards we can see? If so, that's wrong too. The whole floor should have been covered in 3/4in ply, including the area where the tray goes, then the tray put on top of the ply. And the wall tiled after that.

You need to chop the bottom row of tiles off and fit a classi-seal

there's also a side seal that's a two piece design that overlaps so there's a bit of flex.
