Phew, you can really give someone a scare – I actually thought these examples were meant to show how it should look or, since they are real photos, that you have already finished renovating. :D
I have a suggestion that you raise the partitions in the showers... maybe a small shelf that is higher up. On the one hand, water would constantly stand there or many bath shampoos etc. would accumulate, on the other hand, a straight shower divider looks better.
Also, I would leave the front under the washbasins open to the floor tiles. It looks more spacious when the floor is visible, the fronts look more elegant when executed flatter and seem to float... but most importantly: the feet then also have space to stand there :)

P.s. Guest WC, the colors are too cold for me
