There’s nothing worse than taking a shower and realizing that a pool of water is quickly forming around your feet. Don’t panic — learning how to unclog a shower drain is easier than you might think. The following three DIY methods are useful for handling minor clogs and are a good first step to see if you can resolve the issue before contacting a plumber.
Quick answer: For hair clogs, start with a plastic drain snake. For soap scum and light buildup, try vinegar and baking soda. If you have metal pipes, boiling water can help too. If the drain is still slow after these steps, it’s time to call a professional.

What Causes a Clogged Shower Drain?
Most shower clogs build up slowly. Hair is one of the most common culprits, but it rarely works alone — soap scum, body oils, shampoo residue, and small bits of debris cling to the hair and gradually narrow the pipe. Over time, water drains slower and slower until it pools around your feet. Knowing the cause helps you choose the right method below.
Before You Start: Safety Tips for Unclogging a Shower Drain
- Wear rubber gloves — hair and drain gunk are unpleasant to handle.
- Never mix vinegar or baking soda with chemical drain cleaners. The combination can release harmful fumes. If you’ve recently used a chemical cleaner, skip the vinegar method and call a plumber.
- Avoid harsh chemical drain openers where possible, as they can damage pipes over time.
Method 1: Unclog a Shower Drain With Vinegar & Baking Soda
One of the simplest and most effective ways to unclog a shower drain is to use vinegar and baking soda. This natural solution is great for breaking down small clogs and cleaning out lingering residue.
Follow these simple steps:
- Wait for the standing water to drain or remove it yourself with a bucket or cup.
- Pour half a cup of baking soda down the drain. If possible, remove the drain cover to make this much easier.
- Slowly pour a half-cup of vinegar down the drain.
- Let it sit for about 30 minutes to allow the mixture to break down the clog.
- Finish by flushing the drain with hot water.
If you can’t remove the drain cover and it’s too difficult to get the baking soda down the drain, you can mix the baking soda and vinegar first, then quickly pour the mixture down the drain. Just be prepared for it to fizzle and expand as you mix it!
This simple solution can often help with minor clogs and freshen up your drain, but it might not be enough for tougher blockages. If the water still drains slowly, repeat the process once, then move on to the next method.
Method 2: Pour Boiling Water Down the Shower Drain
Boiling water can work wonders for clearing simple clogs caused by soap scum, grease, or small bits of debris. However, this method is only safe if you have metal pipes. If your home is fitted with PVC or porcelain, avoid this method, as the extreme heat could cause damage. Not sure what your pipes are made of? Skip the boiling water and try the vinegar and baking soda or drain snake method instead.
Here’s how to use boiling water to unclog your drain:
- Bring a pot of water to a rolling boil.
- Slowly pour the boiling water directly down the drain in two to three stages, pausing for a few seconds between each pour.
- The hot water will help dissolve and flush away the clog, clearing the drain in the process.
If you see some improvement but the water is still draining slowly, you might need to try this method a couple more times.
Method 3: Use a Plastic Drain Snake to Remove Hair Clogs
Plastic drain snakes are handy tools that work particularly well on clogs caused by hair, which is one of the most common culprits for shower drain blockages. These flexible, barbed tools are easy to use and can pull out hair and other debris that may be causing the clog.
Here’s how to use a drain snake to unclog your shower:
- Remove the drain cover.
- Insert the plastic snake into the drain and slowly twist and push it further down.
- Pull the snake back up slowly, along with any hair or gunk that’s causing the clog.
- Repeat as needed until the drain is clear.
Drain snakes are affordable and easy to find at most hardware stores. They’re a great first step in handling stubborn clogs that don’t respond to baking soda and vinegar or boiling water. Once the clog is out, run hot water for a minute to flush away any remaining residue.
How To Prevent Shower Drain Clogs
A few simple habits can keep your shower draining freely:
- Install a hair catcher or drain screen, and empty it after each shower.
- Remove and rinse the drain cover regularly to clear hair before it travels down the pipe.
- Flush the drain with hot tap water once a month to help carry away soap residue.

When To Call a Plumber for a Clogged Shower Drain
DIY methods work best on minor clogs. Call a professional if:
- The clog keeps coming back after you clear it.
- More than one drain — such as a sink, tub, or toilet — is slow or backing up at the same time.
- You hear gurgling sounds or notice a sewage smell.
Water backs up into the shower when you run the washing machine or flush a toilet.
These signs can point to a deeper blockage in your main line. Learn more about the common causes of sewer backups, or let our team find the source with a video inspection and handle any sewage line backup right away.
