Morning all.
Thanks for the replies, apologies for only responding now.

I've taken some pictures that you can see here:

quite happy to take more, though I'm coming round to that the fact that it'll need ripping up and doing again

@Localtiler The individual mosaics are 20mm wide, not sure how think and don't have any to measure I'm afraid.

@MissTiler I spoke to the company that supplied, and they stated mosaics were fine.

When you enquirer about mosaics, did you specify the size you were using?
As Sharon mentioned, it can be a very important question, some are not suitable for anything less than 50 x 50mm.
What's the former made from, I've looked at the spec and can't find much information at all.
It would normally need to be a resin former for mosaic that small.

It looked like many layers of something similar to fibre glass, but it didn't have the hardness of fiberglass.
Almost like a polystyrene, but much harder. I could see the fibres set in alternating layers, cross shape across each other.

Mosaics - alas not

Are you sure they didn't fit the former upside down?

From the photos, the floor looks to be tiled well but the problem has arisen from yourself, the builder, the tile shop and the tiler not communicating about the floor covering - the tiles - this is why the drain plate was higher than the finished floor level. These tiles are not suitable for your floor with this particular shower tray former as the finished height of the drain doesn't suit the tiles. You could have had the floor screeded* to meet the depth for the mosaics to sit on but that would mean most, if not all of the floor, would need doing, which defeats the object of having preformed tray.

* by screeded I mean to flat trowel floor tile adhesive in layers to create the height and to reform the falls of the tray. (not an easy job if you are under time constraints)

Probably the cheapest option would be to tile over the existing mosaics after digging out the redone 300mm to get some falls back to normal.

Would that not damage the tray underneath?

it shouldn't as you have already stated that 300mm around the drain has been redone

Tom could be right about tray. From the pics there doesn't look to be any fall on the tray at all. There should be a specific gradient on the tray that the mosaics follow so as the water naturally runs towards the drain as in the pic below

watching the video clip with the shower on gives me the impression that there is more wrong here than just the tile thickness not being sufficient to overflow into the drain. The water seems to be making a large puddle and not flowing towards the drain as if there is no slope towards the drain! Are you sure the shower base former is fitted the correct way up? or have the tiles around the drain been built up so much that the slope has been almost totally cancelled out?
I can't see a simple solution with the information given but I think it probably needs at least the tiling redoing with a tile thickness that is compatible with the drain thickness.

Probably been better off using something like these.
