Hello everyone,
we are renovating the bathroom and have had new plumbing installed as well as a new shower tray and shower base fitted. Since I’m not very familiar with the installation process, I wanted to rely on a professional company (just like clients in my job can trust that the technical work is done correctly).
Now, however, I’m not sure how to proceed because, from what I understand, a sealing tape should be applied alongside the acoustic isolation tape, and the shower base should be sealed against the wall so that the sealing tape can then be covered with liquid waterproofing membrane.
But I don’t see any sealing tape in the installation (is there acoustic tape that also seals at the same time?!) and I also don’t see that the shower bases fit flush against the wall. The supervisor said the walls are uneven and the tile adhesive would take care of that. If the flexible tile adhesive contains epoxy resin, would that be sufficient for waterproofing? To me as a layperson, that doesn’t seem enough, but maybe I just don’t know enough. Is there a way to add sealing tape retroactively?
I need help and appreciate any feedback or tips!

Spoiler: Your supervisor is giving incorrect information.

Thank you for your feedback, I had suspected as much.
He said everything was finished, and when asked, he claimed the sealing tape was already applied (as shown in the photos) and that there are versions of this tape that can be folded over and others that don’t need to be folded...
So this statement is simply a lie, right?
Requesting a remedy for the defect because it does not meet current technical standards is definitely justified.
And I noticed he hadn’t even fixed the shower tray to the wall; underneath there are only the 4 feet and pipes. He said he would fix it later if we were okay with it. This is really frustrating.
