ᐅ Shower incorrectly installed and part missing during new build by plumber

The move-in date was June 1st. The plumber forgot an in-wall part for the shower. The Grohe shower was purchased by us. He agreed and acknowledged the mistake. Therefore, the finished shower had to be reopened right on time by June 1st. Five weeks later, it is still not completed. The missing part has been installed and the wall sealed again. However, now the shower is leaking. Water continuously runs from the overhead shower and the control valve. The plumber claims it is a design flaw by Grohe. He even wanted to cut into the shower. Oh man. The plumber has made many other mistakes and is quite uncooperative. We still have several defects with him. What are our rights? Especially since it has not been finished even after 4 weeks. We are dealing with the mess, the delay, and have to take time off work, etc. The plumber apparently is not familiar with the shower either. I no longer trust him. If I hadn’t been there on Friday, he would have closed the valve at the bottom with the cover. Water would have flowed into the wall by the liter because he didn’t even think it necessary to apply silicone. The gaps were so large that a finger fit between the shower back panel (one piece) and the control valve. This is crazy. Can I have someone from Grohe inspect this at the plumber’s expense? Some inspections require special tools that the plumber does not have. Currently, we always have to turn off the main water valve to keep it dry. The plumber is willing to cover the repair costs but refuses any further discount despite all the stress.

How should the whole thing have been properly sealed? And more importantly, by whom? The tiler says it should be done by the plumber, and vice versa.
I did not see any sealing collar or similar, neither at the bottom nor at the top.
At the bottom, the structure is as follows:
Wall / waterproofing coat / tile adhesive / tile / shower
I assume there was no sealing in between. Not even with silicone.

At the top:
Wall / waterproofing coat / adhesive (not applied over the entire surface) to attach the shower back panel. Then the panel was cut open, and the wall opened up to install the forgotten part. Afterwards, it was covered again with tile adhesive. / waterproof coating on the visible part of the wall. Then the new shower panel was placed in front, again not fully glued across the entire surface. The installer wanted to mount the shower next. I told him that it should be sealed. Then he came back with silicone. You can also see in the picture how much silicone was needed, or how wide the gaps are in some places.

Okay, I will look into getting an expert opinion or something similar. I would like to set a deadline, but I no longer trust the installer. I actually want someone competent to finish the job properly. But as silly as it sounds, I don’t want to pay for it myself. I don’t want to be stuck with the plumber’s poor workmanship.

Hello

The waterproofing between the wall and the tile is the responsibility of the tiler.
Just based on what I see in the pictures:
Waterproofing the paint sets on such a wall surface is not really possible with the fittings manufacturers I know.
It might be possible with special custom components.
It’s good that the homeowner was economical and took care of the planning and product procurement themselves.
One more criticism for the installer: You have to say that this is simply not feasible this way.
