Shower slope in the wrong direction

Complaining does not solve problems. That it was not noticed beforehand is unprofessional. That it happened is unprofessional. The professional, legally secure way of complaining, returning, waiting, and adding on is not solution-oriented and can cause follow-up problems. Finding out now what should have been done before, so that one would not have to think about it afterward, is the reason for the saying "would have, could have, bicycle chain."

We will have to wait for the notification from the TE whether a problem like a mini-step arises or not, whether the tiler wants to do it or not, etc.

The simplest approach is still an amicable agreement with the craftsman (tiler), who is already on site. And how to approach this constructively has been very nicely written by . Whether theoretically something else should have been done now helps in what way?

I understand nothing and am completely lost, while everyone here has a clear view regarding the slope in the photos :p:rolleyes:

Here is a picture of the current condition

Those are two (2)! Showers!
In the original post, you mentioned one.

Addendum: The question of "why" is of course not generally bad - when it comes to reconstructing an event to learn from it, for example, it is often very purposeful. When it comes to solving an acute problem, often less so. In this respect, it is of course perfectly OK to ask the "what-if" questions - however, these questions are better asked by the craftsmen themselves. The client may not care what the craftsman learns from the mistake in his house - he just wants the mistake to be fixed.

Hello everyone and thank you for your many clear words.

The tiler now admits that he did the work incorrectly and that it is not sufficient to just remove 1 to 2 tiles. After I had an expert on site, it is clear that the entire floor must be removed, a hydro stop must be installed underneath, and the entire shower must be taken apart because achieving watertightness afterwards is impossible. Now he is dismantling the entire bathroom, and then it has to be rebuilt.

And yes, there are 2 bathrooms, the slope is wrong in both bathrooms. :-(

Here is now the consideration that to avoid a big edge, whether we switch to vinyl or re-tile, a 2 cm edge cannot be avoided. :-(

Does anyone have experience with vinyl in the bathroom?
Best regards

I can't say anything about vinyl, but depending on the floor plan, you could also consider a deliberate step. I have had that and found it comfortable and fitting. But it only works depending on the floor plan.

We have tiles in the bathrooms and vinyl flooring fully glued down in the other rooms. So the edge doesn't really bother you - but it depends on the execution and how high it will be.

I would really avoid vinyl in the bathroom. I am a big supporter of vinyl, and when fully glued down, it can also be easily wiped. But in the bathroom, where water really regularly gets on it and stands there? I wouldn't dare to do that.
Between the individual vinyl strips, we also occasionally glued down small grooves that you can see - I would be afraid that water would penetrate there and cause real damage over the years.
I absolutely can't imagine that for the floor of a shower, and otherwise not really in the bathroom either.
