I love the slanted wall, but the space of this giant bathroom seems kinda awkward. I love the natural light, and how clean it looks. I am kind of against windows in bathrooms. it just seems to impede with what a bathroom should be.
I like the idea of having a window in the bathroom, but I hate the mildew and water damage. This is a great idea with having a shower curtain over the window while in use, but open the rest of the time.
