There’s nothing more frustrating than standing ankle-deep in water during your shower.
Tired of a Slow or Blocked Drain?
A blocked shower drain is more than an inconvenience. It’s a daily disruption. Left unresolved, it can lead to worse issues like water damage, foul odours, and mould growth.
This article explores how to fix shower drain problems at home, the most common causes, and when to hand it over to a professional plumber.
Why Is My Shower Drain Blocked?
Understanding the root cause can help you prevent future blockages.
Hair, soap scum, and mineral build-up are the most common reasons your shower drain is blocked. Over time, these materials clump together, narrowing the drainpipe and slowing the flow of water. In older homes, rusted or corroded pipes can also contribute to frequent blockages.
Common Signs of a Blocked Shower Drain
Not sure if your shower drain is blocked? Look for these symptoms.
- Water pools around your feet during a shower
- Unpleasant smells from the drain
- Gurgling sounds in the pipes
- Slow drainage even after cleaning the surface
If any of these sound familiar, it’s time to look into how to clear blocked shower drain issues right away.
Easy DIY Fixes for Clearing a Blocked Shower Drain
Before calling a plumber, there are several safe and simple methods to try at home.
1. Remove Visible Debris
The first step is often the simplest.
Use a pair of gloves or tweezers to pull out any hair or gunk visible near the drain cover. A small hook or wire hanger can also help reach deeper buildup.
2. Pour Boiling Water Down the Drain
Hot water can melt away soap residue and loosen debris.
Carefully pour boiling water directly into the drain in two or three stages, allowing a few seconds between each pour.
3. Use Baking Soda and Vinegar
This natural method works well for mild blockages.
- Pour ½ cup of baking soda into the drain
- Follow with 1 cup of vinegar
- Cover the drain for 15 minutes
- Rinse with hot water
This chemical reaction helps break down buildup and clear mild obstructions.
4. Try a Plunger
A plunger isn’t just for toilets.
Make sure there’s water in the shower to cover the plunger’s base, then plunge firmly several times. This can dislodge small blocks in the pipe.
5. Use a Plumbing Snake or Drain Auger
When the blockage is further down, snaking is often the most effective DIY option.
You can rent or purchase a handheld snake to reach deeper into the pipe. Feed it slowly, rotate as needed, and pull out the gunk.
DIY Not Working? Here’s When to Call a Pro
If you’ve tried all the above and your drain is still blocked, it might be time for professional help.
Plumbers have access to hydro jetting tools, CCTV drain inspections, and motorised augers that can remove even the most stubborn blocks.
In cases where tree roots or pipe damage are involved, DIY won’t cut it.
Professional Techniques for Stubborn Shower Drain Blockages
Let’s explore the advanced tools pros use.
CCTV Drain Camera Inspection
This allows plumbers to identify the exact cause of the blockage with zero guesswork.
Hydro Jetting
High-pressure water blasts through thick blocks, including grease, hair, and soap deposits.
Motorised Drain Augers
These are stronger than hand snakes and used for deeply lodged debris.

How Often Should You Clean Your Shower Drain?
Prevention is all about routine maintenance.
We recommend clearing visible hair weekly and performing a DIY flush (hot water or baking soda + vinegar) every month. If you live in a household with long-haired individuals, increase the frequency.
Should You Use Chemical Drain Cleaners?
They’re tempting but come with risks.
Most chemical cleaners contain harsh ingredients that can damage your pipes over time, especially if used frequently. They may also not be effective against deeper blocks or ones caused by solidified soap and hair.
Opt for enzyme-based cleaners or call a plumber if your shower continues to drain slowly after treatment.
Blocked Shower Drain? Simple Ways to Fix It That Actually Work
Let’s recap the most effective methods.
| Method | Best for |
| Manual hair removal | Surface-level blocks |
| Boiling water | Soap scum, grease |
| Baking soda & vinegar | Mild buildup |
| Plunger | Light-to-moderate blockage |
| Plumbing snake | Deeper or stubborn blocks |
| Hydro jetting (Pro only) | Major, persistent blockage |
External Causes You May Not Have Considered
Sometimes the issue isn’t inside your bathroom.
Outdoor blockages in the main drainage line can also affect shower drains. Tree root intrusion, collapsed pipes, or poor venting in the system may be causing backflow or slow drainage.
In such cases, it’s crucial to consult a licensed plumbing contractor for further inspection.
Final Thoughts on Fixing a Blocked Shower Drain
To sum up, a blocked shower drain is a common issue that’s usually easy to solve if caught early.
From simple fixes like baking soda to more hands-on methods like snaking, homeowners can often handle the problem themselves.
However, if you’re facing recurring blocks, foul smells, or slow drainage that resists all efforts, it’s time to call a professional.
Book your local plumber today and get it sorted before the next backup hits.
