Causes of Bathroom Smells After a Toilet Overflow

Poor Ventilation System

Weak ventilation is one of the most common causes of bathroom smells after a toilet overflow. If not properly ventilated, the odor can linger in the air and be challenging to remove. Additionally, the lack of airflow can cause mold and mildew growth.

Sewer Backup

Regular cleaning allows your bathroom to regain its freshness within 4-5 days, free from any lingering odors.

  1. Combine 1 cup (236 mL or 16 tablespoons) of bleach powder with 1 gallon of warm water.
  2. Adjust the bleach-to-water ratio accordingly if your bathroom is spacious.

The Smell Doesn’t Go Away Because of That, I Think

When your bathroom tiles or walls are of subpar quality, they have a tendency to absorb water. Consequently, when a toilet overflows, the odorous water can permeate these surfaces. This is the source of the persistent smell that lingers despite repeated cleaning efforts.
