Introduction:
The shower drain trap is a curved pipe located at the bottom of your shower drain. Its main job is to prevent odors from entering by trapping water in the pipe. This water seal prevents sewer gases from entering your bathroom as well as allowing wastewater to drain properly.
Just like any other part of your home’s plumbing, shower drain traps can become blocked, leak or stop working properly over time. Common problems include slow water flow, bad odors, gurgling noises and leaks. If left uncorrected, these problems can lead to major plumbing problems and costly repairs.
Regular cleaning and maintenance of your shower drain trap can help keep your drains clean and prevent costly damage. At Stillorgan Drain Cleaning, we provide professional drain cleaning services in Dublin to ensure your shower drains stay in perfect working condition.
In this blog, we will discuss some common shower drain trap problems and how you can fix them quickly before they become a serious issue.
1. Slow Draining Shower: Causes & Fixes
A slow draining shower can be frustrating and is usually a sign of a clogged drain trap. If water is pooling around your feet while you shower or is taking longer to drain than usual, you probably have a blockage.
Causes of a Slow Draining Shower
Hair and soap scum build-up - Hair falls into the drain when you shower and mixes with soap, creating a sticky blockage inside the drain trap. Over time, this slows down the flow of water.
Mineral deposits and debris - Dublin water has a high mineral content, which can cause hard water deposits to form inside the pipes. These deposits, along with tiny dirt particles, can reduce water flow and make the blockage even worse.
How to Fix a Slow Running Shower Drain
Use a drain snake or plunger - A drain snake (a flexible tool) can be pushed into the drain to remove hair and soap deposits. If you don’t have one, a plunger can help remove the blockage.
Try a baking soda and vinegar mixture – Pour one cup of baking soda down the drain followed by one cup of white vinegar. Let it sit for 15-20 minutes and then rinse with warm water. This helps to break up grease, soap and mild blockages.
Fix a hair catcher – You can fit a simple hair catcher over your shower drain to stop hair from getting into the pipes. This is a simple way to prevent future blockages.
If the problem persists, Stillorgan Drain Cleaning offers professional drain unblocking services in Dublin to remove tough blockages and get your shower back to draining smoothly.
2. Shower Drain Smells Bad: Causes & Fixes
Smells coming from your shower drain can make your bathroom feel unpleasant and are often a sign of a problem in the drain trap. If you smell a sewage-like or musty smell, it's important to fix it quickly before it gets worse.
Causes of a Smelly Shower Drain
Dry P-trap (not enough water in the pipe) - The P-trap is a curved pipe at the bottom of your shower drain that holds a small amount of water to prevent sewer gases from coming up. If the shower hasn't been used in a while (such as in a guest bathroom), the water evaporates, causing the smell to escape.
Bacteria and organic buildup - Over time, soap, hair, and dirt can build up in the drain, creating the perfect place for bacteria to grow. As bacteria break down the organic matter, they release a foul odor into your bathroom.
How to Fix a Smelly Shower Drain
Run the water for a few minutes – If the smell is due to a dry P-trap, simply turn on the shower and let the water run for a few minutes. This refills the trap and flushes out the smell.
Use baking soda and vinegar – Pour a cup of baking soda down the drain, followed by a cup of vinegar. Let it bubble for 15-20 minutes, then rinse it out with hot water. This helps kill bacteria and remove buildup.
Use a biological drain cleaner – If the smell persists, try a biological drain cleaner (enzyme-based), which breaks down bacteria and organic waste without using harsh chemicals.
If the smell doesn’t go away, Stillorgan Drain Cleaning offers expert drain cleaning services in Dublin to eliminate tough smells and keep your drains smelling fresh.
3. Water pooling in the shower (drain not working properly):
Causes and Solutions
If water is pooling in your shower and it's taking a long time to drain, it could mean there's a problem with the drain trap or ventilation. Water pooling in the shower is not only annoying, but it can also lead to mold and damage to your bathroom floor.
Causes of Water Pooling in The Shower
Incorrectly installed P-trap - The P-trap is a curved pipe at the bottom of the drain that allows water to escape while preventing sewer gases from coming up. If the trap isn't installed correctly or is placed at the wrong angle, water can't drain properly, causing water in your shower to drain slowly or stagnantly.
Blocked vent pipe - Your plumbing system has vent pipes that allow air to flow through the pipe, allowing water to drain easily. If these vents become blocked by debris, leaves or bird nests, water can't drain properly, causing it to back up into your shower.
How to Fix Water Backup in Your Shower
Check the P-trap installation - If your shower has always had drainage problems, the P-trap may not be properly sloped. A plumber can inspect this and adjust it to ensure smooth drainage.
Clear any blockages in the vent pipe - If you hear a gurgling sound when water drains, the vent pipe may be clogged. A plumbing auger (a long flexible tool) can help clear blockages in the vent system, restoring proper airflow and drainage.
Call a professional plumber - If the problem persists, it may be a deeper plumbing issue. Stillorgan Drain Cleaning provides specialist drain and vent pipe cleaning services in Dublin to fix slow drains and prevent water backlog problems.
4. Gurgling Noises from the Drain: Causes & Fixes
If you hear gurgling or bubbling noises when water drains from your shower, it’s a sign that air is trapped in the pipes. This can cause slow drainage and, in some cases, bad smells. Ignoring these sounds could lead to bigger plumbing problems later.
Causes of Gurgling Noises in the Shower Drain
Air Trapped in the Pipes Due to a Blocked Vent – Your plumbing system has vent pipes that let air escape, allowing water to flow smoothly. If these vents are partially clogged with dirt, leaves, or debris, air gets trapped inside the pipes, causing a gurgling sound when water drains.
Problems with the P-Trap – The P-trap is a curved section of pipe under your drain that holds a small amount of water to stop sewer gases from coming up. If the trap is not working properly, air can enter the drain, making bubbling noises when water flows through.
How to Fix Gurgling Noises in Your Drain
Check and Clear Blocked Vent Pipes – If your shower drain is making gurgling sounds, the vent pipe may be partially clogged. Use a plumbing snake (a flexible tool) to remove debris from the vent. If the blockage is deeper, you may need a professional drain cleaning service.
Ensure the P-Trap Has Enough Water – If your bathroom has been unused for a while, the water seal in the P-trap may have evaporated. Simply run water for a few minutes to refill the trap and stop sewer gases from coming up.
Check for Installation Issues – If gurgling noises happen often, your drain system may not be installed correctly. A professional plumber can inspect it and make necessary adjustments.

5. Frequent Clogs and Blockages: Causes & Fixes
If your shower drain becomes clogged frequently, it can be frustrating and can lead to slow drainage, standing water and smells. Regular clogs can damage your pipes over time, leading to costly repairs.
Causes of Frequent Shower Drain Clog
Soap, hair and dirt build-up – When you shower, hair, soap and dirt go down the drain. Over time, hair gets tangled inside the pipes and soap scum builds up, forming a thick blockage that prevents water from flowing properly.
Hard water build-up – Dublin has hard water, which means it contains minerals such as calcium and magnesium. These minerals stick to the inside of the pipes, narrowing the drain opening and making it easier for blockages to form.
How to Fix and Prevent Frequent Clogges
Use a Drain Cleaning Tool or Snake – A drain snake is a long, flexible tool that can pull hair and debris out of the drain. If you don't have one, a plunger can help clear out clogs.
Install a drain strainer - A simple drain strainer sits over your drain and catches hair before it gets into the pipes. Cleaning it regularly will help prevent future clogs.
Perform monthly maintenance with baking soda and vinegar - To keep your drain clear, pour a cup of baking soda down the drain, followed by a cup of vinegar. Let it sit for 15 minutes, then rinse with warm water. This helps break down soap scum and mineral deposits naturally.
6. Leaking Drain Trap: Causes and Solutions
A leaking drain trap under your shower can cause water damage, odors, and even mold growth if it's not repaired quickly. If you notice water dripping down the shower drain or smell dampness in your bathroom, you may have a leak in your drain trap.
Causes of a Leaking Drain Trap
Loose or worn fittings - Over time, the connections in your drain trap can become loose due to regular use or vibrations in the plumbing system. This can cause small leaks where the pipes join.
Cracks or damage in the trap - If the trap is made of plastic (PVC), it may develop cracks due to age, temperature changes, or poor quality materials. Even metal traps can rust and start leaking.
How to Fix a Leaking Drain Trap
Tighten the connections - First, check all the fittings and use a wrench to tighten them carefully. Sometimes, a small adjustment is enough to stop the leak.
Use plumbers tape or sealant - For minor leaks, wrap plumbers tape around the threads before reassembling the trap. You can also apply plumbing sealant around the joints to prevent future leaks.
Replace the drain trap if it is cracked - If the trap shows cracks or is damaged, the best solution is to replace it with a new one. PVC traps are affordable and easy to install, but if you want a long-lasting option, a metal trap may be a better choice.
