Concerns about en-suite refurb - waterproofing

I am now worrying about the fit of the shower tray (I've spent the whole weekend worry and obsessing over this job)... Will try to upload an image, comments appreciated:

What do the manufacturer's instructions state about installation? What do they say should go over that lip at the edge? The last row of tiles? Some kind of sealing strip? Plasterboard and tiles?

It certainly looks 'wrong' to have the board at the rear going behind the lip at the rear, with the one at the side going along the top of the lip and suspended in mid air.

The crucial thing is to have a stable tray, with no movement. This may involve laying it on a cement base, it may involve lots of woodwork below, but it has to be solid. If the tiles are laid on the board and overlapped down to the tray with a bead of silicone sealant below, if the tray moves when stood in, then the silicone will likely move and allow water penetration.

It's because the tray is too big for the cubicle, it's had to go into the wall... It should look the same all the way around. Is it worrying enough to insist that he changes it, or should I just let him get on with it and trust that it will be okay? Hopefully we will have better luck with the tiler, but I'm not holding my breath...

What about the back edge?

It's a shoddy job

If there was a discrepancy between size then he could have used 6mm hardibacker or wedi foam board in an attempt to fit a sit should be

The random centres on the plasterboard fixings, with a couple in the middle of one board, none at the inside corner base, and no consistency with the boards also shouts out a warning. My intuition is your guy is not doing a good job.

You're right. Initally I was thinking about occasions where the wall has to be channelled slightly into masonry for a bath/tray to fit, but there does seem to be enough space for the tray to slot as the original builders appear to have left an almighty gap behind the plasterboard - another sign of the one-fix bathroom. We replace the stud work in CLS and place hardiebacker down to the the floor and make the wall fit the tray. He's also screwed the board into that flimsy metal stud that they make new houses with - another reason to replace the studwork in CLS.

Ultimately, they seem to have one guy who hasn't used any forethought when considering what he's going to find behind the original tiles. New builds are worse than traditional houses.

Oh dear oh dear, this isn't good at all is it
Should I cut my losses and just tell him not to come back, and get someone else to finish the job?

Do you have a contract? Quotation? What's in it?

It isn't rocket science, but what needs to be done needs to be agreed. I don't know what falls under this £760.

What you want is the right job at a sensible price - and I mean expensive enough to reflect the amount and standard of work.

Realistically it's a 4 day job, with a value of £1200 plus door and tray

Day 1 rip out, sheet, fit tray and tank

Day 2 tile and grout

Day 3 silicone tray edge, fit shower valve etc . Most skip this stage and fit the enclosure then seal. You must seal behind the profile and allow the grout to cure before silicone

Day 4 fit enclosure and silicone outside edge

The quotation states:
Complete decommission of old shower cubicle
Supply & fit of new shower tray, shower door, shower valve, pipework, waste, fittings, silicone, tile adhesive and grout
Labour of plumber and tiler
Removal of all waste

So, based on all the good things we had heard, we just went with it.
