The door still has to be moved to the right, I just heard :/
Uff, uff... :(
masonry shower wall (approx. 110 wide x 130cm long)
...glass is out of the question. The wall is definitely to be masonry and tiled on the inside of the shower.
I assume you want a tiled shower because then you don’t have to clean glass? With your measurements (length 130) the water will still splash further - I was about to say that it’s actually already as good as you designed it yourself, but the space in front of the toilet will probably get a bit wet. If the door is now also pulled further into the room, then you will get a nice partition wall behind the door (to see it positively :) ) Your wish will not become easier... if the door is moved, then there are no interior walls yet?! Take a look at whether one or the other can be changed, otherwise the door to 84 width (or whatever the standard is) and opening towards the hallway.
