Shower tray or tiled shower?

.. aren’t the tiles used there quite smooth and therefore slippery?

I have mosaic tiles in the level-floor shower at my place. I always find that quite pleasant on the feet, it just conveys that. I have also showered in showers with large tiles and there I always felt like I had to move very carefully.

It is definitely also recommendable to equip the shower with underfloor heating loops.

I agree. We currently have a walk-in tiled shower without underfloor heating – fortunately only rented – and I would definitely not want to implement it that way myself.

Our tiler advised against a tiled shower, but we had already decided on an ultra-flat shower tray beforehand. The potential for errors in sealing multiplies with every joint, and what have I gained if after 7 years I notice that a joint has been leaking for 2 years? The mold is there, the tiler is out of warranty, the floor is damp, and I have the mess... with a shower tray I only have to check the silicone joints at the edges. We have clear glass shower walls, the squeegee hangs in the shower, and instead of wiping the glass for 2 minutes after showering, Silit Bang has to be used every 4 weeks for 20 minutes.

yes, we also feared the slipping. The tiler said you could have the tiles invisibly laser-treated - we forgot. But it is not smooth. Whether that is because it is granite, I cannot judge.

Before we had an acrylic shower tray and currently an acrylic bathtub, where I have slipped slightly more easily... So no worries.

Mosaic is also very beautiful, especially when you pull a strip up the wall.

we have underfloor heating in the bathroom, but not in the shower. There are no cold feet or unpleasant foot sensations there, because the tiles warm up immediately through the water - although they weren’t really cold before.

I am rather a bit annoyed about the open shower, it was more comfortable before in the closed cabin.

Open like this is stylish, but I wouldn’t do it again.

...it is easier for the developer to install a shower tray.

We do not have a developer. This was said by an independent site manager/supervisor.

With a note similar to Egon12:

The potential for errors when waterproofing multiplies with every joint, and what have I gained if after 7 years I find out that one joint has been leaking for 2 years? The mold is there, the tiler is out of warranty, the floor is damp and I have the mess....with a shower tray I only have to check the silicone joints at the edges.

My experiences are, as written, exactly the opposite. However, my experiences are not based on a new build, but on an existing building from the 1970s. It may be that in new buildings the "base temperature" in the floor otherwise supplied with underfloor heating is different. For us, it is definitely unpleasant. I do agree with you that the feeling of warmth in an open shower is generally not as good as in a closed cabin. It is colder because the warm water vapor freely drifts into the room instead of being contained in a cabin. Without a wide-area rain shower, that would also be a significant criticism of the open design.
