I'm playing around with floor plans right now and came across a bathroom-related issue that I'd like to briefly discuss.
And that is that the bathroom in my house will likely be in a converted attic. It's a hipped roof with a 30-degree, max 35-degree slope, an 80-cm lap floor, and as a result the bathroom will probably have two slopes.
To use the space wisely (I want to use higher areas for a separate shower and washbasin) and because I also find it quite cozy (like looking outside when it rains or a light breeze in summer), I would like to place the tub under the skylight.
I asked myself:
Aside from the ceiling height issue, is there any downside to placing the tub directly below the skylight?
I often see this in pictures, but what is often done is not necessarily always good.
What spontaneously occurred to me is this:
Does the window always fog up when you bathe and you can't see anything anyway, or do the droplets drip off?
"Cold air 'falls' into the window in the winter, so it's easy to get a draft in the bathroom when you're wet, or is that not the case with modern windows anyway?
Since I like to take baths long and often, it's important to me that I don't get my plans wrong.
Above all, have fun building.
The idea of a skylight is good, you may also like a fixed segment window. So called knee-level windows.
It's clear that condensation water is the biggest danger to building a house, but it depends on the insulation of the roof/exterior walls, etc. Д.
We have 2 skylights that are mounted on the roof at a 25 degree angle! No water, because the temperature in the bathroom is at least 24 degrees.
Cleaning: of course, you have to remember that something like this can be a trap. You can get in the tub, but on a stool in the tub? Without help, it's suicide.
It also depends on how often you bathe! Our bathtub is too big, so it is used less than expected!
I think windows directly over the bathtub are clumsy, and will only do them if all other options are worse.
With or without a window.... An 80 cm floor knee at a 35° roof pitch makes for a pretty small headspace for entry/exit.
I have a 48° slope, a 90 cm knee floor, and a bathtub on a slope. However, we recessed the tub about 7 cm into the loft recess and made a 30 cm shelf towards the knee floor. I wouldn't want to move it further under the slope, even though we're not all that tall. You should also keep this in mind when planning.
My guess is that the bathroom will need more heat capacity as a result, and yes, it will be cooler underneath than it would be without the skylight.
There are remedies to combat fogging.
So our bathtub is under a skylight with a 1.10m knee height. We think it's all nice and airy, and we personally haven't noticed any disadvantages in that regard, except that it's a little more inconvenient to clean the window because you have to stand in the tub to do it.
But we certainly don't use the tub as often as you described.
I don't think I would be comfortable bathing under an "open" blanket.
You can't look out when it's raining either. And in fact, when I take a bath, I probably don't so much look out as close my eyes and enjoy the warmth.
