ᐅ Bathroom Ideas

I am looking for some ideas for the bathroom.
Attached is a drawn floor plan. It is an existing building.

The wall to the children's room can still be moved. The room might currently be too large?
The wall next to the toilet is just an idea, as is the shower.
There is a sloping roof, and it is planned to have a double roof window.

So far, I am not really happy with my ideas. Maybe one of you has a great suggestion.

I would also like a large oval bathtub set in a built-up base directly below the windows.

I would prefer to make the children’s room larger.

And this staircase is already installed and functional? Somehow, it seems to be missing some steps.

Currently, the bathroom is 4 meters (13 feet) wide instead of 4.80 meters (15 feet 9 inches) as shown on the plan.

But either way, I am having difficulty with the planning.

The staircase exists and works. The number of steps was just not transferred correctly.

The toilet is below 2 meters (6 ft 7 in), which does not comply with DIN standards. A bathroom of 15 sqm (161 sq ft) is actually quite spacious, almost too large.
I would move the door so that the room behind it can also be furnished.

Then maybe it would be best to leave the rooms as they are.

The right wall of the children's room is currently, as mentioned, 80 cm (31 inches) further to the left.

Swap the bathtub and toilet. Keep the width at 4 m (13 feet). 15 sqm (160 sq ft) is, in my opinion, too large—although a bathroom can hardly be too big 😉—but it’s definitely an expensive bathroom.

We have just under 8 sqm (3.28 × 2.45 m / 10.76 × 8.04 feet) with a 90 × 180 cm (35 × 71 inches) bathtub, 90 × 120 cm (35 × 47 inches) shower, 65 cm (26 inches) washbasin, toilet, and space for a cabinet (fairly behind the door)—I find it doesn’t feel cramped at all. A room that has worked well in practice.
