A clogged shower drain can be more than just a minor inconvenience. If left unchecked, it can lead to standing water, bad odors, and even damage to your drain pipes and fixtures. Common culprits behind shower drain clogs include hair, soap scum, and body scrubs. 

Fortunately, there are several effective methods to unclog a shower drain that you can try yourself before needing to call a professional plumber like Intown Plumbing. Follow these steps in order, starting with the simplest techniques and progressing to more advanced methods if necessary.

1. Use Boiling Water

One of the easiest and quickest ways to address a clogged drain is to pour boiling water down the drain opening, as advised by the EPA. Here’s how to do it:

  • Let the water drain: Ensure that all the water has drained completely from the shower.
  • Boil water: Heat a large pot of water until it reaches a rolling boil.
  • Pour the boiling water: Slowly pour the boiling water down the drain opening. This can help break down any grease, soap scum, or other debris causing the blockage.

Note: Do not use this method if you have PVC pipes, as the extremely hot water can damage them.

2. Clean the Drain Cover

Often, the cause of a slow drain is a blockage right under the drain cover. Cleaning the cover can significantly improve water flow. Here’s how:

  • Remove the drain cover: Carefully take off the drain plug or cover.
  • Clean the cover: Remove any hair, soap scum, or debris caught on the cover. Use a metal coat hanger or a hair clog removal tool to fish out debris if it’s too deep to reach with your fingers.
  • Wear gloves: To protect your hands from bacteria and sharp objects, wear gloves during this process.

These same steps often apply to other fixtures, so knowing how to unclog a bathroom sink can also help you manage buildup throughout the bathroom.

3. Baking Soda and Vinegar

For a chemical-free solution to your clogged drain, try using baking soda and white vinegar. The chemical reaction between these two ingredients can help dissolve clogs naturally.

  • Prepare the solution: Mix ⅓ cup of baking soda and ⅓ cup of white vinegar.
  • Pour it into the drain: Once the shower has completely drained, pour the mixture into the drain opening.
  • Let it sit: Allow the solution to sit for 20 minutes to an hour, giving it time to dissolve the blockage.
  • Flush the drain: After the solution has sat, run hot water down the drain to help flush away any remaining debris.

If you live in a home with a septic system, make sure you know what drain cleaner is safe for septic systems before trying chemical alternatives.

4. Use a Plunger

If the slow drain persists, a plunger can help create suction and dislodge the clog.

  • Remove the drain cover: Take off the drain plug to access the drain opening.
  • Add water: Fill the tub or shower area with enough water to cover the plunger cup.
  • Create suction: Place the plunger over the drain opening and push down and pull up rapidly to create suction that can break up the clog.

5. Use an Auger/Plumbing Snake

For more stubborn clogs that are deeper in the drain line, using a drain snake or plumbing auger may be necessary.

  • Remove the drain cover: Take off the drain plug or cover.
  • Insert the auger: Insert the auger into the drain opening, rotating as you push forward.
  • Break up the clog: Continue pushing until you feel resistance, then rotate the auger to break up the clog.
  • Pull out the clog: Once the clog is caught, retract the auger to remove it. Run hot water to flush the drain and ensure flow is restored.

Learning how to use a plumbing snake properly can make this method even more effective for deeper or stubborn blockages.

If you’ve tried these methods and the shower drain remains blocked, it might be time to call in a professional plumber. Persistent clogs could indicate more serious issues like a blockage in the P-trap or drain line.
