Why Does My Bathroom Drain Smell Like Sewer? Causes & Solutions

When organic matter decomposes in your drain, hydrogen sulfide gas forms, producing that classic sewer stench. Ignoring the issue not only worsens the smell but can lead to costly pipe damage over time.

Sealing cracks and maintaining moisture in P-traps with a few drops of water can prevent drying and bacterial buildup. Regular maintenance, such as periodic cleaning and avoiding harsh chemicals, keeps drains fresh and odor-free.
