Over time, these substances often accumulate along the P-trap and vertical pipes that run underneath your shower. This accumulation is called biofilm. As it builds up, biofilm begins to release a sewage smell from bacteria and decomposing debris.
Leaky pipes in your bathroom walls or under the shower can allow sewer gases — also known as hydrogen sulfide — to escape, so you may notice the shower drain smells like rotten eggs or sewage.
There are several potential reasons why you might smell bad even after showering. These include not washing thoroughly enough, not changing your clothes regularly, not drying off properly after showering, not changing your towels frequently enough, and wearing fabrics that don't allow your skin to breathe.
If your shower drain smells like sewage and the cause is a dry P-trap, it's usually the result of a broken, clogged, or obstructed vent line. Vent lines can be difficult to identify and run along the roof of a home, so it's safest to contact a professional plumber to help.
To find the source of that stinky smell, turn to the building's plumbing system. Check sinks, drains, toilets, and other plumbing fixtures for obvious signs of damage, leaking, or loose connections. It's also good to check sewer vents and the clean-out drain outside the building.
If dry, the p-trap cannot perform its function correctly. To eliminate odors coming from a dry p-trap, pour half a gallon of water into the trap to restore the barrier. It will prevent the odors from seeping through the drain.
Key Takeaways. Dry P-traps can cause sewer gases to escape and create foul odours. Blocked vent pipes can prevent proper airflow, leading to sewage smells in your home. Cracked sewer pipes may release gases into your house and cause unpleasant smells.
Other than draining slowly or not at all, the smell in your shower will let you know if the P-trap needs cleaning. If your shower smells like sewage or has a foul odor, your P-trap is most likely not functioning properly.

Answer: Only under extremely unusual circumstances. Although hydrogen sulfide is a toxic gas, it will not harm people at the concentrations that exist in a house with sewer gas odor problems. Studies have shown that hydrogen sulfide has a depressant effect on the central nervous system in concentrations above 150 ppm.
Everyone has sweat glands, but some people have overactive ones. This means you might sweat more than usual, even after a shower. More sweat equals more food for bacteria, which equals more odor.
Mold is often described as smelling musty. Others have described mold as having an earthy or meaty odor, resembling the smell of wet socks or rotten wood. For many homeowners, the smell is unpleasant and pungent. As mold grows, it can emit gasses known as microbial volatile organic compounds, or MVOC's.
Clear away debris, leaves, or bird nests that might be blocking the vent. Ensure the vent stack is working correctly to allow sewer gases to escape. Inspect and Replace Wax Ring: If you suspect that the sewer smell is coming form around your toilet, you may need to inspect and repalce the wax ring seal.
P-Trap Problems
But a dirty P-trap that's blocked by buildup like hair and soap scum can't do its job properly. Another P-trap-related issue that can make your drain smell like sewage is a dry P-trap, usually caused by a clogged ventilation line or other problem with your plumbing vent.
But if there is a sewer smell in the house, similar to that of rotten eggs or cabbage, you may have a sewer gas leak. Gasses off-put by the sewer are a byproduct of the breakdown of waste. But the pungent smell they create is not just disgusting – these gasses can be dangerous as well.
A regular sewer-gas smell is just a bad stink with a definite odor of feces and sometimes a rotten-egg (hydrogen sulfide) smell and/or a moldy mustiness too.
Baking Soda and Vinegar Solution
This classic combination can help clear out minor clogs and eliminate odors: Pour half a cup of baking soda into the drain. Follow it with a cup of vinegar. Let the mixture sit for 15-20 minutes.
Sewer gas produces a very distinct rotten egg smell, caused when organic materials break down and decompose to form hydrogen sulfide. If you're unsure about the smell coming from your drains or sewers, call a licensed plumber who can perform an inspection or clear and clean blockages.
Common Causes of Bad Odors in a Home
Some common culprits include: Bacteria:Some strains of bacteria give off foul-smelling compounds when breaking down organic matter like food waste. Fungus: Molds and mildew emit volatile organic compounds and are often the cause when a house smells musty.
First, open all windows and doors to let as much fresh air inside as possible. Clean or replace all air filters, furnace filters, and AC filters. Clean walls and ceilings using products with ammonia and glycol — two ingredients that neutralize bad odors. Let the walls dry and check if the odor persists.
Some common synonyms of stinking are fetid, fusty, malodorous, musty, noisome, putrid, and rank. While all these words mean "bad-smelling," stinking and fetid suggest the foul or disgusting.
