Shower element vs. sloped screed

The floor tiles in the shower are mosaic tiles format with us, due to the risk of slipping. At the same time, they are also a design element in the bathroom/shower area and door threshold transitions between the rooms. The screed was installed by the screed layer as a sloping screed, the tiler sealed and tiled it.

Hey,

Now Vicky and I finally agree on something.
The slope from the screed layerer. In my opinion, the reason is solely the sealing. If you have a floor-level shower, the joint you create there with your bagged mortar sounds like a potential flaw. For floor-level showers, the entire bathroom up to the door and the door frame must be sealed. This service is provided by the tiler. If you end it there, the sealing has to bridge this joint. I always find that bad per se.

We handle it exactly like Vicky. The slope comes from the screed layerer and then the tiler can go wild.

doesn't mean that your opinion is correct

then the tiler can let loose.

But the tiler will probably rather let loose in his work, because then he knows that it is the way he wants it. He also does the waterproofing. The whole bathroom. I also don't like having raw material made or given to me in advance by another craftsman - and then I have to fix the crap again... no thanks.

All three variants seems to work.

We have an element and tiles were laid on it, and now the tile grout is coming loose.

I would construct the shower without grout.

For level-access showers, the entire bathroom up to the door and at the door frame must be sealed up to a height.

you then also have a step at the door which belongs there according to DIN

does not mean that your feeling is correct

Absolutely. That’s why I explicitly write according to my feeling. All three options work and for the reasons mentioned I prefer one. But that’s what communication here is for.

Best regards, Jann

I don't know tileable shower elements – is that hardware store stuff for amateurs?

I don't think so. We also had a tileable shower element installed. It's a smooth thing.
They are now available in all variations. Also with pre-integrated shower drains (tileable or not) or drains of all kinds.
Some can only install dry screed on the upper floor, and such an element is really great. Especially because you know that everything is watertight.
