5 Tips to Make Perfect Toilet Bombs

  • Liquids like water or dish soap should be added a few drops at a time to prevent activating the citric acid.
  • Ensure you have the right consistency, similar to wet sand, before placing the mixture into the molds.
  • If the texture is too wet add more baking soda, if it is too dry add more liquid.
  • If you are not experienced in making toilet bombs or bath bombs add essential oils to the wet ingredients.
  • The colorant should be added to dry ingredients if using powder and to wet ingredients if it is liquid.

NOTE: Although citric acid is considered safe by the EPA, some people might be sensitive to citric acid, so just to be safe use gloves, protect your eyesight and ensure the area is well-ventilated.

Also, make sure to keep away from kids and pets.

Wait until it settles to unmold. To accelerate the drying process or to make the tablets harder, place the molds for a little while in the freezer.

I have used big silicon molds like the type you use to make soap. Then I cut each tablet into smaller pieces.

  • 1 or 2 tablespoons of dish soap or Castille soap
  • 30 drops of your favorite essential oils

In a bowl mix baking soda and citric acid.

You can add the essential oil at this point. I have used 15 drops of geranium essential oil and 15 drops of orange essential oil.

If you are using colorant add it now. I have used blue powder mica colorant but forgot to add it at this time.

If you want to use liquid colorant, add it to the dish soap or water.

Using a spoon, start pouring the dish soap. Be careful here and do it slowly to avoid activating the citric acid. Stir the mixture.

Once you are satisfied with the consistency place the mixture into the molds.

I didn’t add water but if you think the mixture is still dry you could add more water. But remember to add the water a bit at a time as you check the consistency.

3. Toilet Bombs Without Citric Acid

Ingredients to make toilet bombs without citric acid


  • 1 cup of baking soda
  • 1/3 cup of Epsom salt
  • 30 drops of essential oil
  • colorant (optional)
  • water
  • ice cube tray or bath bomb molds

Instructions to make them

Combine the baking soda and Epsom salt. Add the colorant now if you are using one. Just to clarify add colorant if you are using powder. If the colorant is liquid add it to the wet ingredients.

Add water slowly until you achieve the right consistency. It should feel similar to wet sand and don’t fall apart.

Also, ensure the mixture is not too wet because this could activate the ingredients even when the toilet bombs are ready.

Fill in the two halves of the bath bomb mold. I like to overfill the molds to make the toilet bomb more compact.
