1. The function of the toilet is to provide drainage and cleaning, and it belongs to a relatively private area. The bedroom is a private space for rest and relaxation, which conflicts in function.
2. The bathroom usually produces moisture and odor. If not properly designed, these moisture and odor may affect the air quality and living experience of the bedroom.
3. From the perspective of geomantic omen, the bathroom should be hidden. If there is a bathroom outside the window, you can see the bathroom window from the outside, which may affect the overall image and feng shui of your home.
Therefore, having a bathroom outside the bedroom window is not the best design. If there is such a design, you can try to improve this problem by changing the window position of the bathroom or installing private curtains.
