Why is my shower drain smelling like sewage?
A pleasant shower experience is the perfect way to start or end your day on a refreshing note! However, when foul odours emanate from your shower drain, it can quickly turn into an unpleasant experience. The good news is that you don’t have to endure the stench any longer. In this blog, we’ll explore why shower drains develop bad smells and provide effective methods to eliminate them, leaving your bathroom fresh and inviting.


Causes of Bad Smells in Shower Drains
Understanding the root causes of bad smells in shower drains is crucial in order to address the issue effectively. Here are some common culprits behind unpleasant odours:
Accumulated Hair and Soap Scum
Hair, soap scum and grime can build up over time, creating a breeding ground for bacteria and other microorganisms. These organisms break down the organic matter, releasing some foul-smelling gases! Yikes!
Clogged Drains
When debris, such as hair, dirt, or foreign objects, block the flow of water through the drain, it can lead to stagnant water. This stagnant water becomes a breeding ground for bacteria and mould, which will smell bad!
Plumbing Vent Issues
Sometimes, the unpleasant smell might not originate from the drain itself. Blocked or damaged plumbing vents can cause sewer gases to seep back into the bathroom through the drain, resulting in a less than ideal smell.
How to Eliminate a Bad Smell from a Shower Drain
Routine Cleaning
Regular cleaning is the first line of defense against bad smells in your shower drain. Remove the drain cover and clear out any visible hair or debris. Mix a solution of equal parts hot water and vinegar and pour it down the drain. Let it sit for 15-30 minutes before flushing with hot water. This will help break down and remove soap scum and kill bacteria.


Baking Soda and Vinegar Treatment
For more stubborn odours, you can use a combination of baking soda and vinegar. Pour half a cup of baking soda down the drain, followed by half a cup of vinegar. Cover the drain and let the mixture foam and react for 15 minutes. Flush it with hot water to clear out the residue.
Commercial Drain Cleaners
If the odour persists, you can opt for a commercial drain cleaner. Be cautious when using these products, as they can contain harsh chemicals that may damage your pipes or harm the environment. Follow the instructions carefully and consider natural or enzyme-based cleaners as a safer alternative.
Preventive Measures
To avoid future occurrences of bad smells, implement preventive measures. Install a drain cover or strainer to catch hair and debris, preventing them from accumulating in the drain. Regularly clean and maintain the drain and avoid pouring grease or other substances down the drain that can cause clogs.
Seek Professional Help
If the odour problem persists despite your best efforts, it may be time to call a professional plumber. They can conduct a thorough inspection, identify any underlying issues with your plumbing system, and provide the necessary repairs or replacements.
In Conclusion
Don’t let bad smells from your shower drain spoil your bathing experience or make your bathroom an unwelcoming space. By understanding the causes of these odours and implementing the methods mentioned above, you can banish the unpleasant smells and enjoy a fresh, clean, and inviting shower every time. Regular cleaning and maintenance, along with preventive measures, will help keep your shower drain odour-free in the long run. Remember, if the problem persists, it’s always wise to seek professional assistance to address any underlying plumbing issues.
