In this comprehensive guide we explain why bathroom pipes smell, what you can do to eliminate the problem and when it's essential to call in a professional. If the smell persists, the Lisbon Plumber company is the best solution to solve the problem once and for all.
Main causes of bad smells in bathroom pipes
Bad odors never appear for no reason. It is usually associated with specific faults in the sewage system.
1. Dry or incorrectly installed siphon
The siphon has the function of creating a water barrier that prevents sewer gases from rising. When it is dry, poorly installed or damaged, the smell rises directly into the room.
2. Accumulation of waste
Hair, soap residue, body fat and hygiene products accumulate in the pipes, causing decomposition and a bad smell.
3. Lack of plumbing ventilation
A pipe without proper ventilation creates negative pressure, causing sewer gases to back up through the drains.
4. Partial blockages
Even if the drain is not completely blocked, a partial blockage can lead to the retention of waste and the appearance of odors.
5. Hidden leaks or infiltrations
Small leaks inside the wall keep the humidity constant and create an ideal environment for bacteria and mold.
6. Sewer connection problems
Incorrect or faulty connection to the sewage system can allow gases to be released directly into the bathroom.
Simple solutions to eliminate bad smells
Before turning to a professional, there are a few solutions you can try out.
1. Check and clean the siphon
Dismantle the siphon from the sink or shower and thoroughly clean out any accumulated debris.
2. Keep drains moist
In drains that are rarely used, pour water regularly to keep the siphon barrier active.
3. Cleaning with bicarbonate and vinegar
A mixture of baking soda and vinegar helps to neutralize odours and loosen light residues.
4. Cleaning the shower drain
Remove the grill and remove accumulated hair and soap, one of the most common causes of bad smells.
5. Avoid aggressive chemicals
These products can damage the siphon and aggravate the problem in the medium term.
When home remedies don't work
If the bad smell returns quickly or never disappears completely, it's a sign of a more serious plumbing problem.
- Poorly dimensioned or defective siphon
- Deep blockage in the pipe
- Lack of ventilation pipe
- Water leaking inside the wall
- Problems with the building's sewage column
In these situations, insisting on temporary solutions only delays the correct repair.
Risks of ignoring bad smells in pipes
In addition to discomfort, sewer gases can pose real risks:
- Proliferation of bacteria
- Respiratory problems
- Increased humidity and mold
- Damage to the structure of the property
- Environmental contamination
According to Directorate-General for Health, environments with excessive humidity and mold can negatively affect respiratory health.

It is advisable to call in a professional when:
- The smell is constant and intense
