Reasons of Bathroom Odor:
1. Fungus
The main reason for the smell in the bathroom is fungus. This is due to leaks in pipes or plumbing fixtures. Fungus also forms if the area is constantly wet due to water leakage. So the water leak should be fixed. Water stagnation will cause fungus or algae. To prevent the bathroom from smelling, make sure that air can circulate in the bathroom. Also, it should always be kept dry.
