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

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

The wall basically extends out into open space. I had also considered using tiles, but the highest point is 2 cm (0.8 inches) and then it slopes down to zero. The installed tiles are porcelain stoneware, but they will probably break, and unfortunately, I won’t be able to cut them cleanly.
Is that structurally sound?
The vinyl at the transition isn’t firmly fixed.
Do you know what I mean?
I found a photo of the renovation on my phone and edited it.
On the left, the highlighted area is now the vinyl, and towards the wall, there is a slope of 2 cm (about 0.8 inches) that levels out to 0 towards the room.

If you glue the rail to the wall with silicone and then create a silicone seal along the transition at the bottom of the tile, it will hold very securely. The only thing is that the approximately 1mm (0.04 inch) metal strip, which is normally embedded in the tile adhesive, will be beneath your vinyl. I’m not sure if this will be noticeable.
Since it needs to be permanently watertight, I would spend about 20 euros and get a cartridge of MS Polymer. My home shipyard, and not only that one, even seals hull penetrations underwater with it. Permanently watertight. MS Polymer, trade name Pantera, is rarely found in building supply stores far from the coast but is available for purchase online. Unlike silicone, it adheres extremely well, even to fingers, can be painted over, sanded, remains permanently flexible, and is highly water-resistant. It can also be used as an adhesive. It cures more slowly than silicone, so allow an extra day. Karsten
I have now ordered the rail on Amazon and will try to slide it under the vinyl, the opposite of what you suggested.
I also found the adhesive on Amazon for 8 euros. Unfortunately, I’m not allowed to post links, otherwise I would have shared it to check if it’s the right one.
Would regular construction adhesive possibly work here as well? The other product seems really difficult to apply, judging by the reviews.
