Shower
I have had a shower put in it was pooling he’s now put another in but it’s not draining he said it’s cause it’s a concrete shower tray I said it’s plastic he said it’s not so I assume it’s resin . Should I expect water left in tray

No, you should not expect water to pool in your shower tray after it's been used. While some residual water might remain due to surface tension, a significant amount pooling indicates an issue with the shower tray's installation or a problem with the drainage system. It's likely that the shower tray isn't level or has a manufacturing defect causing it to hold water
No the tray should be level and it should have a natural fall to the plug hole
Hi. No water should all drain. The tray is designed and shaped to direct water to the waste. If the tray is holding water i would suggest that this is not on a level base which is why you have water holding.
Minimal water their shouldn't be any major puddling the tray base should be level in both directions edge to edge the tray bottom has a natral fall
That definitely doesn’t sound right — even with a resin (or stone-resin) shower tray, water should drain away completely if everything’s installed properly. A bit of very light pooling that clears after a few seconds can be normal with ultra-flat trays, but if it’s holding water noticeably or draining really slowly, something’s off.
Whether it’s resin or plastic, the tray should be installed level (or with a slight fall toward the waste), and the waste itself should be clear and properly connected — if it’s not draining, that usually means:
The tray isn’t sitting level or is back-graded, so water's fighting gravity.
There’s a partial blockage in the waste pipe or trap.
The waste isn’t sealed correctly or is kinked/crushed underneath, especially if space was tight.
The shower waste itself is low-flow or poor quality, struggling to handle the volume.
Worth noting: resin trays are heavier and firmer than plastic, but you can usually tell by feel — if it’s got a stone-cold touch and feels super solid underfoot, it’s likely resin. Plastic trays are usually more hollow and flex a little.
So no — you shouldn't be left with standing water. It’s worth pushing for a proper inspection of the waste and the tray level. Want some tips on how to test the gradient or check the waste for blockages without ripping everything up?
No because the water should always drain downwards to the waste trap of the shower, so therefore the shower tray has not got a very slight slope, to ensure proper drainage and prevent water from pooling.
No
If water is pooling in the shower tray and not draining properly, that’s not normal, regardless of whether the tray is resin, plastic, or another material.
A properly installed tray should have a slight gradient to direct water toward the drain.
Here’s what could be going wrong:
1. Tray not levelled correctly – even a resin tray must be installed with a proper slope.
2. Blocked or poorly fitted waste trap – can slow drainage or cause pooling.
3. Incorrect fall on pipework – if the waste pipe doesn’t have enough slope, water won’t drain efficiently.
4. Confusion about the material – resin trays are common and heavier than plastic. If your tray feels solid and heavy, it likely is resin.
Bottom line:
You shouldn’t expect water to be left sitting in the tray after a shower.
It should fully drain away within a few minutes at most. If it doesn’t, the issue likely lies with the installation, not the material.
No should never be water left in the tray.
