ᐅ Bathroom layout with sloped ceiling in the attic

Hello,

we are planning to create a bedroom and a bathroom in our attic.
In terms of space, the bathroom doesn’t offer many options, so we are considering placing the sink, radiator, and bathtub in a single line. However, the toilet is relatively narrow in width, which hopefully won’t be an issue for us.
Each square in the layout represents 10cm (4 inches), with dimensions rounded up or down to the nearest 5cm (2 inches).

Thanks for your feedback

When finishing the interior, every centimeter counts. A 60 cm (24 inches) space for the toilet is too narrow. Measure and draw carefully, or note down the exact dimensions. A 2 m (6 feet 7 inches) ceiling height line is important. What is the roof pitch? Do you definitely want a bathtub?

Add the window to the plan, including its dimensions and the height of the windowsill.

Well, you do need some space to move around in the toilet, even if you gain 10 kilograms (22 pounds). But even slim people need to be able to move their arms.
To me, the height dimensions look more like those of an attic space. There’s no window, right?
Maybe consider installing sliding doors in front of the sloped ceiling instead of a sliding-door wardrobe, and use that area as a closet, and perhaps set up something like a bathroom within that closet space (whatever that room is).

There is an elevation line at 180 cm (70.9 inches). To the left of that, how low does it go? Is this the area where the pipes come up from below? How is the WC drain pipe supposed to run?

I would see storage space mainly to the left under the assumed roof slope, and the wall on the right might still be adjustable.

A complete floor plan of the level would be very helpful.

I thought I read 30cm (12 inches).

I’m now also thinking that the toilet area might be too tight, so it would be better to install a built-in cupboard there and forgo the bathtub in favor of a shower. We already have a bathtub on the first floor. This way, the sink, radiator, toilet, and shower can be arranged differently.

I have already asked in another thread how to connect the waste pipes, especially from the toilet to the soil stack in the basement. This is puzzling to me due to the required slope of at least 1cm (0.4 inches) and the pipe thickness.

Attached is the total floor area of the attic. The wall marked in red was not built at that time.

The current small roof window would be removed and replaced with one of the same size as on the other side.
