Common Causes of Sewage Smell in Bathroom

Clogged Drain

Hair soap and dirt clog drains. The clog traps sewage waste. Bacteria grow in the clog. This causes a bad smell. A clogged drain needs cleaning. Use a drain snake or cleaner. Regular cleaning prevents this issue.

Broken Sewer Pipe

A cracked sewer pipe leaks gases. The smell enters your bathroom. This is a serious issue. It needs professional repair. Look for wet spots on walls or floors. Call a plumber if you suspect this.

Faulty Wax Ring

The wax ring seals the toilet base. If it breaks sewer gases leak. The smell will be strong near the toilet. Replacing the wax ring fixes this. You may need a plumber for this job.

Vent Pipe Issues

Vent pipes let sewer gases escape outside. If blocked the gases come back inside. Birds leaves or debris can block them. A plumber can check and clear the vent.
