Is a tile height of 2 meters in the shower enough?

Well, 210 cm is not exactly a shelf either. At least I haven't come up with that idea in my bathroom despite being 180 cm tall. If it is supposed to look nice, grout lines should not be more than 2 to 3 mm. With 8 rows, then 1.5 to just under 2 cm due to grout lines.

Don't you have a shower now where you can see how high you splash?

Originally, we had planned a 1.20m tiled partition wall with an attached glass panel between the open shower and bathtub. I didn't order the glass panel through the plumbing company but wanted to get it later through a relative (glass industry).

In the meantime, we have completely given up on the glass panel because the splashing is very limited.
My wife doesn't splash upwards anyway due to the method "showering without hair" (Mario Barth), and for me (1.73m) it only splashes onto the partition wall, not beyond it.
Even though we aren't very tall, I dare to doubt that you splash higher than 2m.

So when I see how high I wipe the water off the tiles every time – it’s at head height already. It may also depend on which shower setting you use. The rain shower, the waterfall shower, or a stronger setting of the hand shower.

Hello everyone,
thanks first of all for all the contributions.

So the idea was now from the tiler to have 8 tiles everywhere, about 2 m high, finishing the rest on the L-wall with the wood tile at the top.
With 9 tiles up the walls we would most likely be above the top edge of the door, I would find that ugly. (This is how it is here in the apartment, even if it’s only a little overhang, that just doesn’t work.)
We came up with that idea this morning and searched our current shower wall from all possible angles for splashes. They really only go up to 2 m, or there are very few there. However, the tiles here are also only about 2.06 m high, if it splashed above that, you don’t really see it at the moment. In this respect, we see the whole issue a bit more relaxed. One could also do a 10 cm strip made of the normal wall tile on the "normal" wall inside the shower, I thought. The room has to look nice from the middle of the room or when you lie in the tub – but this spot is only visible when using the shower, so whatever. Higher than the partition wall would rather be an optical problem.

Regards

Off the top of my head, I just thought of: Are you planning a tiled decorative strip possibly as a top finish? Maybe this could also bridge the remaining centimeters (after subtracting the joints).
