The first possible cause of sewage odor in your bathroom can be the components. If you have and utilize them just recently the water in the P-trap can vaporize and this gets rid of the barrier in between the bathroom and the gases in the sewage systems. The easiest option is to run your water and Philip P-trap once more.
Most people would presume that the toilet would be the main perpetrator for a sewage scent but the water in the toilet bowl functions as a sort of smell obstacle. If your toilet bowl isn't completing the way it must be the issue might be broken seal. This can be changed fairly quickly by you might not want to try it and hiring the water damage remediation business would be your finest choice.
Whatever the source of the scent it is vital that you have it handled rapidly. Breathing in hazardous fumes is bad for you and not good for any individual else in your household's home.
