The bathroom door cannot be directly opposite the house door, otherwise it is easy to get sick. It is a bathroom itself and cannot be converted into a bedroom or dining room.
It is best not to install a bathroom in the bedroom. If necessary, keep the bathroom ventilated. The door of the bathroom must not face the bed, let alone the head. The partition wall between the bathroom and the room cannot be made of glass, otherwise it will easily lead to marriage trouble.
The water in and out of the bathroom is a top priority, especially the water outlet. It should be close to the sewage canal or main pipe, and must not be hovering indoors. This will be detrimental to the health of your family.
