ᐅ All-inclusive bathroom on 8 m² (approximately 86 ft²)

Hello everyone!

Since construction will start in a few weeks and we have decided to make the house a bit more compact based on the offers, we are now planning our bathroom.

This is already very important for us because the bathroom is located on the ground floor. There is no basement, so we need to finalize the base plumbing now.

Requirements:

We want a fully functional bathroom, preferably with two sinks, a toilet, a bathtub, and a walk-in (built-in) shower without glass.
The door on the left should provide access to the garden.
Access from the bedroom is not desired; the bathroom should continue to be accessible through the dressing room.
The 45° angle would almost be a natural choice here, as this would make the access to the bedroom less cramped and dark, while the space behind the bathtub would not be needed. Moving the bedroom door downward in the plan, to align with the bathroom wall, is not possible because we need that wall as a support (otherwise, a beam with steel lintel would be required).
The bathroom is mainly for my wife and me; the children have their own bathroom.

What do you think of this idea? My architect said he could only imagine it if the sloping shower wall were made of glass.
Is the 5.5cm (2 inches) space between the bathtub and the door enough?

Should I worry about water always getting onto the area near the toilet while showering, or should it work? If only a little water drips out, which is probably the case, that would be fine with us.

Do you have any other ideas in advance? The rough construction dimensions are currently about 2.63m x 3.15m (8 ft 8 in x 10 ft 4 in), the position of the garden door is completely flexible (also possible at the top of the plan), and the door from the dressing room to the bathroom could be moved slightly downward in the plan.

Thanks a lot in advance for your help and ideas! 🙂

Best regards, Mathias
