Hello everyone,
I’m currently working on floor plans and came across a point regarding the bathroom that I’d like to discuss briefly. The bathroom will most likely be located in the converted attic. This is a hipped roof with a 30 to max. 35 degree pitch, an 80cm (31 inch) knee wall, and the bathroom will probably have two sloped ceilings as a result.
To use the space efficiently (I plan to use the higher areas for the separate shower and washbasin) and also because I find it quite cozy (e.g., looking out while it rains or enjoying a light breeze in summer), I would like to place the bathtub directly under the roof window. Depending on the space for getting in, I would of course adjust the bathtub position accordingly, possibly with a built-up frame or drywall construction—or whatever is best practice—but that’s not the question here.
What I’m wondering is: besides the issue of ceiling height, are there any disadvantages to placing the bathtub directly beneath the roof window? I do see it often in pictures, but what is common practice isn’t always the best.
A few things that come to mind:
Will the window always be fogged when bathing so you can’t see out, or will water drip down the glass?
In winter, does cold air “fall” from the window and cause a draft in the bathtub when you are wet, or is that no problem with modern windows anyway?
Since I enjoy long and frequent baths, it’s important to me to avoid planning mistakes here.
I don’t have a floor plan to share yet, as I’m still working on the overall layout and for now just want to clarify this question to see if it’s even a viable option.
Thanks in advance for your opinions and experiences.

In the bathroom, you simply lack the floor space under the bathtub, toilet, and sink, so compared to other rooms of the same size, you are missing about 2-3 square meters (21-32 square feet), possibly another 1 square meter (11 square feet) if there’s a shower. So, in a 12 square meter (129 square feet) bathroom, you end up with only about 8 square meters (86 square feet) of heating surface, and you still want to reach 24 degrees Celsius (75°F). If there is a skylight, that leads to additional heat loss… so I would calculate very carefully with a conservative approach.
Those are extra costs that might come on top of the skylight. The original poster wasn’t aware of that until just now… so I wouldn’t say it’s not a problem.

Yes, but then there’s additional wall heating. That’s not a problem at all

...But you can’t just say that without knowing the actual floor area of the bathroom and how closely the heating loops are spaced. That depends on many factors and has very little to do with a double casement window above the bathtub.
Our bathroom also has a partially constructed knee wall but is comfortably warm, so we often turn the thermostat down to 1—and yes, this works independently from the other rooms.
