Why Does Your Shower Drain Smell in the First Place?
Common Causes of Drain Odors
Before jumping into solutions, it’s important to understand the source of the problem. Shower drain odors can stem from several things:
- Soap scum and hair buildup: These can clog the drain and create a breeding ground for bacteria.
- Mold or mildew growth: Warm, moist environments foster fungal growth that can lead to musty smells.
- Dry P-trap: If a drain hasn’t been used for a while, the water barrier in the P-trap may evaporate, letting sewer gases escape.
- Sewer gas leaks: A more serious issue if your plumbing vent is blocked or damaged.
How to Identify the Source
- Smell intensity: Is the odor mild or overpowering?
- Drain performance: Slow drainage often indicates a buildup.
- Visible gunk: Lift the drain cover and check for hair, grime, or standing water.
Quick Home Remedies That Actually Work
Baking Soda and Vinegar Flush
This classic combo is a go-to for natural cleaning:
- Pour 1 cup of baking soda down the drain.
- Follow it with 1 cup of white vinegar.
- Cover the drain and let it fizz for 15 minutes.
- Flush with hot water.
The fizzing reaction helps break down gunk and kill bacteria naturally.
Boiling Water Method
If the odor is minor and there’s no major blockage, boiling water can work:
- Bring a pot of water to a boil.
- Carefully pour it down the drain in stages.
- Repeat 2-3 times a week as preventive care.
Lemon and Salt Scrub
Lemon is a natural deodorizer, and salt acts as an abrasive:
- Cut a lemon in half.
- Sprinkle coarse salt onto the cut side.
- Scrub the drain cover and surrounding area.
- Rinse with warm water.
Deep Cleaning Your Shower Drain
Remove Hair and Debris Manually
Manual cleaning is essential for persistent odors:
- Remove the drain cover with a screwdriver.
- Use a drain snake or plastic hair remover tool (available on Amazon).
- Pull out hair and grime from inside the drain.
- Rinse with hot water.
Tip: Wear gloves and keep a trash bag nearby.
Clean the Drain Cover and Surrounding Area
- Use an old toothbrush with dish soap or baking soda.
- Scrub the cover, tiles, and around the drain opening.
- Wipe down with a damp cloth.

Frequently Asked Questions
Q1: What causes a smelly shower drain?
A smelly shower drain is usually caused by a buildup of hair, soap scum, bacteria, mold, or a dry P-trap. In some cases, it can be due to sewer gas backing up through the pipes.
Q2: How do I get rid of a bad smell coming from my shower drain?
You can eliminate the odor by using a baking soda and vinegar flush, pouring boiling water, scrubbing the drain with lemon and salt, or using enzyme cleaners. Manual removal of hair and debris also helps.

You should clean your shower drain every 1–2 weeks with hot water and do a deeper clean with baking soda and vinegar at least once a month.
