You should remember that toilets and bathrooms are places to relax, and being pressed by something is equivalent to pressing on the relaxed owner. Will you feel comfortable?
Another toilet is the place where the human body removes dirt, and the connection between the roof of the carport and the toilet is equivalent to communication. I guess the door of your toilet shed still belongs to the carport? This stench will always affect your means of transportation. Travel will lead to dirty air on your body, which is not good for travel!
I'm not superstitious about Mr. Feng Shui. I am a scholar who studies Zhouyi scientifically, and I only pay attention to science, so you'd better separate the shed from the toilet, leaving a seam of about 20cm as long as they are not connected together! That's it.
hope this helps
