Hoping someone can help. I am in despair having discoverd I might have to pull out newly installed bathroom fittings and a floor, as the newly installed shower tray is unstable and moving and tiled ensuite floor is creaking. I've been playing detective to try and find out (in reverse order of works) which of the following is to blame:
1. The tiler - seemed to do a good job of laying the Fired Earth porcelain tiles but I noticed he has tiled right up to the stone resin shower tray, with no expansion gap at all.
2. The plumber – careless in ways too numerous to mention (and has since been replaced) but I do remember that he cemented the shower tray in, which is, I gather, the correct procedure.
3. The builder – paid thousands of pounds to repair/replace the rotten joists below the bathroom floor and lay chipboard, ready for the tiler who laid down hardibacker once the shower tray was in.
The builder swears blind that it is not his fault and blamed it on the tiler for failing to leave an expansion gap. But it can't be the tiler's fault that the shower tray is moving, can it?
Any help/feedback/advice on how to move forward with this – ideally that doesn't involve ripping an entire Fired Earth tiled floor up.
Thanks in advance.
