Help! Tile former shower problem

[MadProfessor]

We’ve just moved into a new build property. All six bathroom seems to have a problem with the shower where instead of the water running down into the drain it runs off to another part of the bathroom where it pools and obviously can’t drain.

Every bathroom is fully tiled with a walk in shower with shower screen. There does seem to be fall to the shower line but it’s clearly not sufficient.

I’m wondering whether this is a complete c*ck up by the tiler / bathroom fitter and house it should be corrected. One possible explanation is that they have fitted particularly large shower heads on quite long shower arms. Perhaps this means that the shower water is falling the wrong side of the fall line and running off.

Anybody have a clue and is there any rule about the size of the shower enclosure / tile former to the size of the shower head/arm?

Obviously we’re chasing the developer but...

In case anybody cares about the answer, a spirit level reveals that the four of the bathrooms are flat as the proverbial pancake.

Two are fine now after a combination of ensuring the screens were actually fitted correctly and the pressure was adjusted on the shower heads.

How are they going to fix them?.

They’re going to re-do the floor including the underfloor heating and tile former. Let’s hope they don’t damage any of the sanitary ware and have to replace that as well. Or the wall tiles.
