Tiling shower partition wall at different heights - designing transitions

Yes, it was about the transitions between the differently tiled areas at different heights. The wall becomes thicker at the bottom. Living with that, as well as 2.10 tiles, tiling only up to the bathtub height on the bathtub side (unfavorable due to splashing water when the minor adventurer is sitting in the tub) are the alternatives. Unless you have other ideas.

The tub shifts slightly to the right, centered between the partition wall and the room wall. Nevertheless, I would still want some tiles there.

There used to be tiles with a finishing edge that you could insert there. Unfortunately, I haven't seen them for ages.

I also don't really like tiles that simply "stop" and form a step... in one bathroom, we had the wall plastered up to tile height (it had to be plastered anyway... otherwise it's a complicated solution) -

here you can see my "hippie solution" for another spot

For that, the plaster had to be recessed a bit (removed) (scored with the angle grinder)

Times and tastes have changed o_O
I still have the one from a few years ago and like it when it looks handmade ... ;)
