ᐅ Shower Unit vs. Sloped Screed

The floor tiles in our shower are mosaic tiles due to slip resistance. At the same time, they serve as a design element in the bathroom/shower area and as threshold transitions between rooms. The screed was applied as a sloped screed by the screed layer, and the tiler sealed and tiled over it.

Hey,

Now Vicky and I finally agree on something.
The slope should be done by the screed installer. In my opinion, the reason for this is solely the waterproofing. If you have a level-access (curbless) shower, the joint you create with your mortar mix poses a potential risk of failure. For level-access showers, the entire bathroom up to the door and the door frame must be waterproofed. This is the responsibility of the tile installer. When you leave it up to the tile installer, the waterproofing has to bridge this joint. I always find that problematic.

We handle it exactly as Vicky does: the screed installer creates the slope first, then the tile installer can work freely.

Best regards,
Jann

The slope from the screed installer. The reason, in my opinion

does not mean that your opinion is necessarily correct

But the tiler will probably have free rein in his work because he will then know that it is exactly as he wants it. He is also responsible for the waterproofing. The entire bathroom.
As a tradesperson myself, I don’t like to have raw materials prepared or supplied by someone else beforehand—and then have to fix their mistakes... no way.

It seems to apply to all three options.

We have an element that was tiled, but now the grout between the tiles is coming loose.

I would install the shower without grout.

Do you then also have a step at the door? According to DIN standards, there should be one there.

Absolutely. That’s why I specifically wrote “according to my perception.” All three options are valid, and for the reasons mentioned, I prefer one of them. But that’s exactly what communication here is for.

Best regards, Jann

I am not familiar with tileable shower elements – is that DIY store stuff for amateurs?

I don’t think so. We had a tileable shower element installed as well. It’s a smooth solution.
They now come in all kinds of variations, also with pre-integrated shower drains (tileable or not) and all kinds of drainage options.
Some upper floors only allow for dry screed installation, so such an element is really useful there. Especially because you know the whole system is waterproof.
