ᐅ Optimizing Floor Plans and Bathroom Layouts with Sloped Ceilings

Hello everyone,
we are building with a general contractor and are working on the bathroom layout. In the image below, there is a roof slope at 45°, and on the left, the window measuring 1.05m (3.4 feet) is fixed. The door within the hallway, as well as the partition wall to the children's room, could be moved. The chimney will not be built and was mistakenly drawn in.
Our original wish was for a shower without glass (which now seems hardly feasible, so we are slowly becoming open to alternatives) and a sink with a minimum width of 100cm (39 inches).
In the image, you can see our second attempt, as delivered to us by the planner. However, our general contractor now says that we are too far under the slope with the shower (along the 2m (6.6 feet) line; the 2.3m (7.5 feet) line is incorrect) and it would be too tight. Therefore, we would be interested to know if you agree with this assessment and how far we would have to shift things (it will probably be too tight with the sink and the door, so we might, if necessary, move a bit into the children’s room). Since we would like to avoid that, we would also be open to alternative ideas.
Thank you in advance.

No, it doesn’t work that simply. You have rough construction dimensions. Also, a bathtub should not be installed too tightly, just like the washbasin.
So if you’re unlucky, only 68cm (27 inches) of the 76cm (30 inches) will actually be usable. That’s not functional.
I also wouldn’t place a washbasin directly in front of a window, as you might not be able to open it anymore.
Where is the downpipe planned on the ground floor?

I think you should proceed as follows: 1. have the draftsman create a correct set of drawings (if the 230mm (9 inches) line were the only mistake here, it would be Christmas and Sunday today); then show us 2. the entire attic floor (not just a section), 3. for context, which is very important, also the entire ground floor, and 4. a cross-section parallel to the gable. In the meantime, take a look at the Town & Country Flair 113 as an example of how a building proposal of this type looks successfully as a bestseller.
I notice a series of errors and oddities here, without claiming to be complete and listed below in no particular order or priority. There are structurally questionable collar beams shown, which according to their position in the floor plan are located above the lintels of the gable windows. These windows are supposed to have a height of 1.70m (5 ft 7 in), starting from a sill height of 94.5cm (37 inches) — according to Eva Zwerg, the lintels therefore begin at 264.5cm (8 ft 8 in). Even if no shutter boxes are installed on top, the underside of the collar beams can hardly be significantly below 290cm (9 ft 6 in), and thus probably above the attic floor ceiling. So what on earth is the informational value of marking the beams on the attic floor plan? It would only make sense if the beams acted as supporting girders limiting the room height. At least the window height measurement is probably incorrect. Even at 1.30m (4 ft 3 in), the gable windows would be unsuitable for a shutterless design (or surface-mounted shutters). According to the drawing, the bathtub drain will be located above the stopper—I would classify this as "unfriendly usability." In the shower, the fixture will likely be installed in the drywall (i.e., from the side), and to place items, one has to lean forward beneath the slope. The draftsman should write an essay on how they imagine transporting things between the attic and ground floor—that would surely be entertaining to read. With this level of spatial imagination, one shouldn’t become a draftsman—is this floor plan an AI fake?
Your improved drawings will be easier to discuss if you orient them the same way as the original.

.. and what is the height of the knee wall?The knee wall here is probably 33 cm (about 13 inches) high (in the standard Flair design, it is 76 cm (30 inches)). But I think the draftsman hasn’t asked the AI about the cross-section yet ;-)https://www.instagram.com/11antgmxde/

hanghaus20235 Sep 2025 12:18Hello @11ant Your answer somewhat misses the point of the question. The question is not about what the draftsman did wrong. It is assumed that the window in the children's room should have the same sill height. The question to the original poster is: what is actually wrong? The sill height or the window height? In my suggestion, any sill height works.
