ᐅ Walk-in shower completed and issue with waterproofing

Hello everyone.
I am new to the forum but have already read a lot here regarding our major renovation.

About our problem.
A walk-in shower was installed. I should mention right away that it was done not by me but by my uncle, who is actually a trained tile setter.
I was not always present during the construction work.
The shower was tiled after all the preliminary work, with the appropriate slope. So far, so good. I have now laid the flooring in the rest of the bathroom (vinyl), assembled and installed the shower enclosure, etc. Now I wanted to finish by applying sanitary silicone sealant to the shower, and that’s when I noticed a big problem that my uncle just shrugged off.
At the start of the shower, the floor (tile and vinyl covering) is level. That’s fine, however, the slope was made only in one direction and as a result, I now have a wedge at the edge that is not covered by anything. At the lowest point, it is 2cm (0.8 inches).
What can I do here to make the whole area watertight?

Unfortunately, I don’t have any pictures at the moment because I am on my honeymoon. However, I found a picture from when the tiling was done.
The slope is marked in red. Everything without tiles already has vinyl flooring installed, and the shower enclosure is also mounted and resting on the vinyl.

I hope you can help me with this problem.

Thank you in advance for your help.

Best regards

EDIT
I just noticed the image didn’t upload correctly. The internet here is excellent... not ^^
I hope you still understand what I mean.

Okay, thanks. It’s ordered.
I’ll test it out and then provide feedback.
Thanks for your help.

Then confidently seal all the other edges in the shower with it as well.
This way, you won't have any mold problems. The polymer is very resistant to it. If it were cheaper, it would be used much more often in construction. Even shrinking screed performs better with it due to its 400% elongation at break compared to silicone, without cracking. Karsten

May I ask which porcelain stoneware you used in your shower (name and manufacturer)? I find it visually very appealing and am also looking for tiles / porcelain stoneware for the shower.

Sorry for my late reply

First of all, the trim worked. It was a bit fiddly but it fit well. Thank you very much for your help.

I bought the tiles at OBI. They are still available there. I specifically looked for the receipt, but it does not show the manufacturer. Sorry about that.
Only fzg City gray.

Maybe you can make something of it.

But personally, I would never install porcelain stoneware tiles on walls again. I ruined two drill bits when fixing the bathroom fittings, both of which were brand new and specifically designed for porcelain stoneware and granite.
However, cutting the holes was easy using a diamond drill bit attachment with the angle grinder.

Thank you for your response. Great that the trim worked out. I’ll check at OBI to see if I can find something there. The tile installation will be done by a professional, so that’s not my concern.
