Sewer Odors in Bathroom. DEAR TIM: We recently have begun to notice a sewer odor from only one of the three bathrooms in our house. It might be the toilet, but it's hard to tell. The smell is not constant and some times it is very strong. Everything in the house drains fine, including the toilet with the odor.
A rotten egg smell is usually caused by an animal in the ventilation system. Sometimes a small rodent or bird will crawl into the vent while sick, or become trapped inside. Once the animal dies, the decomposing carcass gives off the smell. Once you turn on your HVAC system, the smell fills the entire house. Ventilation and duct cleaning is the best method to solve this smell.
