I apologise to anyone still monitoring this thread for not giving you the final outcome. Having stripped the tiles and as much cement as possible from my first attempt I re-tiled using adhesive apparently specifically designed for tiling on wood and a flexible grout (powder). It made no...

I left a 2mm gap and siliconed it, no grout. Most of the cracks are on one wall only. Good point, I don't know what makes the wall move.

OK, I'll bounce up and down in there and see if I can spot anything. The tray is stonecast and the platform is 4 x 2 (all edges supported plus 2 cross pieces) and 12mm ply, everything screwed and glued. Should be fairly solid I'd have hoped.

Thanks Gcol, I will try flexible grout then (no update here for a while as I won't being doing it until the rest of refurb). The tray support is pretty substantial, is built up from the concrete underfloor, feels solid and the silicone does not seem to have separated from the tray or wall. The...

OK, extra silicone hasn't helped at all. There are hairline cracks in several tile joints so presumably the wall is moving. In a month or two I will start the rest of the bathroom refurbishment. I will have to decide whether to rip out the shower and start again (I'd rather not) or see if...

I sealed the tray to the wall before fitting the enclosure, then sealed the OUTSIDE of the enclosure. Perhaps I should consider sealing the INSIDE too in case you are right - I guess if any water found its way behind the frame it would escape by the same path you suggest. This does not seem to...

I meant to say it's just the grout that's cracked. Nick

The cracking is around mid height and affects both walls at the same level across most of the columns with a short vertical crack at the one end, before it reaches the frame. I don't understand this either as all the plywood joins are vertical - one wall is a single piece, the other has a...

I think you were right - wall movement! Not at the tray, which is very solid, but a few tiny cracks in the grouting. I did notice that the studs were on 600mm centres, not 400mm, and were a bit smaller than the usual 4 x 2 (3.5 x 1.8 ish). It is hard to estimate the amount of water leaking...

Thanks gcol. It is hard to say exactly how much water escapes, perhaps an eggcup full after two showers. It doesn't flood out but wets surrounding timber, including the chipboard flooring (see later). In the main it emerges at the wall/tray/frame intersection (hard to be sure if that's all) and...

Thanks for the suggestions. I can still access the trap beneath the tray and can feel no wet from there. I will double check the connections to the shower mixer by coming through the (stud) wall from behind, but I did check connections before fitting the ply and thought they were OK. The...

Help please! Last week I installed a new shower in my daughter’s flat and it is leaking, I think through the tiled walls. I built the walls of 12mm WBP exterior ply sealed with (one) coat of oil-based primer, as suggested on the tile-cement tub. The cement is waterproof and specifically claims...
