ᐅ Electrical outlets in the bathroom???

Hello,
We are currently planning the electrical outlets, but we are not quite sure where to place them in the bathroom. There should be at least one outlet near the washbasin – but where exactly?
I hope you can help us with this.

If the shower has a fixed partition at least 2.25 m (7 ft 5 in) high on the door side, electrical outlets are only permitted on the left side of the washbasin.

Hello, the shower is open on both sides ;-)

Hello,
that will be difficult!

Right next to the door?

Is it not allowed to have an electrical outlet on the back wall of the shower (like here, an open shower with an outlet at the washbasin), even though no water from the shower can splash onto it?
I am just an interested layperson.
