Shower tray pooling

dyslexicwinker

We bought a new build a year or so ago. Not many issues and generally get what I want/need but have had some interesting discussions regarding the en-suite shower tray which pools at the back. Having spoke to the manufacturer (ideal) they have said it’s potentially defective so builders have agreed to change but they’re adamant that due to it being within ‘tolerance’ then potentially it could become worse and there are no guarantees. Having fitted shower trays previously I’ve not had one that pools away from the plug as surely that’s not the idea! Assume they’re ‘trying it on’ but does anyone have any experience of ideal trays and do their tolerances allow pooling?

Photo please?
And, do you have a spirit level?
As you suspect, it'll come down to one of two causes - the tray itself is defective by being distorted somehow, or it hasn't been installed correctly = 'level' (Ie, the tray has the correct built-in 'fall', so should - in itself - be installed completely level.)

We’re on our second ideal shower tray with pooling and our house builders have stopped part way through installing the third as it pooling in the same spot. I fear I’m getting stuck in the middle of a debate on tolerances between ideal and the builder.

Do either of you have Legal Protection in your house insurance? If so, call them up for advice.

Retained water in the tray can be caused by surface tension, or by a poor moulding. The tray must be installed level if it has an integral slope or drain towards the waste. Do not level the tray off of the 'upstands' if it is an upstand tray. It should be levelled via the rim. A good installer will level across diagonals also. Some trays will bow. Depending on the severity; will depend on if it needs replacing or not. A pool and drain test should have been performed prior to tiling and walls....A defective tray can easily be replaced at this juncture. An upstand tray tiled in on three sides replacement can sometimes be a pain. Much easier to spot tray defects or negative fall on waste pipes when the home is still considered a 'site'. Often retained water in the tray needs to be quantified as a volume as most manufacturers allow an amount to be retained due to manufacturing tolerances.
