First, the simple answer. If you haven’t scrubbed in a while, bacteria and biofilm have thrown a wild party under the rim. That gunk releases sulfur gases, which smell like rotten eggs.
The fix? A good scrub with a pumice stone or a bleach-based cleaner. It’s a five-minute job that makes you feel like a cleaning wizard.
But wait—if the bowl is spotless and the smell persists, we’re not done. The plot thickens.
The Sneaky Culprit: The Vent Pipe
Your toilet has a secret weapon: a vent pipe that runs up through your roof. It lets sewer gases escape outside. If that pipe gets blocked by leaves, a bird’s nest, or frozen condensation, the gases have nowhere to go.
They bubble back up through your toilet water. That’s why you smell sewer every time you flush. It’s not your fault; it’s a roof problem.
The fix? Call a plumber to snake the vent. It’s surprisingly cheap and instantly fixes the funk. You’ll feel like a detective who cracked the case.
