Although chemical drain cleaners are sometimes effective, they may also damage the pipes as well as harm the environment. The good news is there’s plenty of ways that you can unblock a shower drain without resorting to harsh chemical solutions.

  • To use wire hanger method Straighten the wire hanger and leave the other end in its original shape and then create a hook on the top, and then place it into the drain to fish hair and other debris out.
  • For wet/dry vacuums switch the vacuum to "wet" mode and cover drains overflowing with cloth or tape, join the hose and create an airtight seal. Turn on the vacuum for 3 minutes.

Method 1: Bake Soda and Vinegar

Step 1: Gather Your Materials

To begin you can gather the following items:

  • Baking soda
  • White vinegar
  • Boiling water
  • Rubber gloves (optional)
  • A cloth or rag

Step 2: Prepare the Drain

Get rid of the shower drain cover if possible and use a small brush or toothbrush to remove any hair or other debris around the edges of the drain. Be sure to wear rubber gloves if necessary.

Step 3: Pour in Baking Soda and Vinegar

You can pour one cup of baking powder down your drain, followed by one cup white vinegar. Then cover this drain immediately with a clean cloth or a towel to ensure that the reaction doesn’t go out of control!

Step 4: Wait

It should take about 30 minutes while the mixture does its work. There should be some sound and bubbling. That’s a sign that it’s working!

Step 5: Flush with Boiling Water

Remove the cover with care and flush with boiling water. This should help clear all debris remaining and help make sure that the water flows smoothly again.

Method 2: Wire Hanger

Sometimes all you need is a sturdy wire hanger

Step 1 Step 1: Straighten It Out

Straighten a wire hanger to the greatest extent as possible, while keeping the other end of the hanger in its original shape.

Step 2: Create a Hook

Create a small hook on the top of the wire that you have just straightened.

Step 3: Fish for Hair and Debris

Place the hook in the drain and fish around to look for hair as well as debris. Get rid of anything that comes up.

Method 3: Wet/Dry Vacuum

If you have access to an air-tight vacuum, this method might be for you.

Step 1. Set the Vacuum

The vacuum should be set on "liquids" or "wet" mode.

Stage 2: Seal Drainage

Cover any overflow drains with duct tape or a wet cloth to ensure the highest suction power.

Step 3: Attach Hose to drain

Attach the hose onto your drain to create an air-tight seal.

Step 4: Turn on Vacuum

Then, turn on the vacuum and allow it to run for approximately three minutes. This should remove any blockages in your shower drain.
