DIY Fizzy Toilet Bombs


Fizzy toilet bombs…to combat those not so nice toilet bombs.

Okay okay, I know, that’s gross! But not untrue!

These super easy 4-ingredient natural, toxic-free toilet bowl cleaners will have you ditching that chemical stuff faster than you can say “woohoo!”

The use of baking soda and essential oils means that soak up all that gross odour while giving off a much nicer one! The scent you want depends on which essential oil or oil blend you use.

The recipe contains baking soda, citric acid, liquid Castile soap, and essential oils.

If you’re able to get these ingredients in bulk it can be a true zero-waste DIY. Living in a small town I don’t have access to many bulk options but we do have a bulk bard 35 minutes away, which has become somewhat of a second home. I buy my baking soda and citric acid from there. Unfortunately, unlike baking soda, they don’t offer citric acid in bulk so it came in a package.

I buy Dr. Bronner’s liquid Castile soap in a bulk size to limit the amount of plastic bottles I go through. For this recipe I use Dr. Bronners Tea tree for extra antibacterial properties and a scent boost.

My essential oils are a mix of Doterra, Now, and a local vendor who makes her own therapeutic grade oils.

To use these toilet bombs simply plop one into your toilet as often as you want. Once a day or once a week, whatever floats your boat. Let it fizz and then scrub up the sides of the bowl with a toilet brush.


This recipe makes 12


  • 1 cup baking soda

  • ¼ cup citric acid

  • 1 Tbsp liquid Castile soap

  • 20 drops antibacterial essential oil (ex: grapefruit, lemon, tea tree, eucalyptus)



  1. In a glass bowl mix baking soda and citric acid.

  2. Mix in Castile soap and essential oil of choice. You don’t have to limit yourself to just one essential oil. Blends are wonderful too! Mixture should be crumbly but packable.

  3. Pack mixture into a silicone mold. I use a silicone baking tray but large silicone ice cube trays work well too.

  4. Let it sit on your counter for up to 24 hours but as little as 6 hours.

  5. Store in an airtight container.
