Fizzy Bath, Toilet & Shower Bombs

Fizzy Bath, Toilet & Shower Bombs

🌱 A simple fizzing bomb for fragrance and bathroom freshness

 

These little fizzers aren’t really cleaners - they’re fragrance bombs.

When they hit water, they fizz and dissolve, releasing essential oils into the air. That fizzing action comes from a reaction between bicarbonate of soda (alkaline) and citric acid (acidic). The reaction is fun, fast, and temporary - and its main purpose is scent, not scrubbing.

They’re easy to make, nice to have on hand, and a simple way to freshen bathrooms without synthetic fragrance sprays.

 

What these fizzers are

These fizzers are designed to:

  • Release fragrance into steam or water
  • Freshen bathrooms and toilets
  • Create a pleasant sensory experience

They are not designed to:

  • Scrub surfaces
  • Remove stains or build-up
  • Disinfect

Think of them as a scent tool, not a cleaner.

 

Where they work best

You can use the same base recipe for different purposes.

In the shower

Place one on the shower floor, away from direct water spray. As it slowly fizzes, steam carries the essential oils into the air - similar to a shower steamer.

In the toilet

Drop one into the bowl for a quick refresh between proper cleans. It fizzes, releases scent, and dissolves away.

In the bath

Use as a light bath fizzer for fragrance and atmosphere. These aren’t moisturising bath bombs - they’re simple fizzers.

 

Why bicarb and citric acid fizz

When bicarb (alkaline) meets citric acid (acidic) in water, they react and release carbon dioxide gas. That’s what creates the fizz.

Once the reaction finishes, what’s left behind is essentially salty water - which is why these don’t clean anything. The value is in the fragrance release, not the residue.

Recipe & Instructions

Ingredients

  • 1 cup bicarbonate of soda
  • ½ cup citric acid
  • 10–20 drops essential oils (optional)
  • Spray bottle with water

Makes

Approx. 6–8 small fizzers (depending on mould size)

Method

  1. Combine the bicarbonate of soda and citric acid in a bowl. Mix well to remove any lumps.
  2. Add essential oils and mix thoroughly.
  3. Lightly spray the mixture with water, a little at a time, stirring constantly.
  4. Stop as soon as the mixture just starts to clump when squeezed — do not over-wet.
  5. Press firmly into silicone moulds or scoop into small shapes.
  6. Leave to dry completely for 24 hours.
  7. Store in an airtight container.

Important making notes

  • Go slowly with water — too much will trigger fizzing too early
  • Dry air helps these set properly
  • If they crumble, add a tiny bit more moisture next time
  • If they expand or crack, you added too much water

Do these clean or disinfect?
No. They release fragrance only. Use proper cleaning products for cleaning or disinfecting.

Can I add soap or vinegar?
No. Soap and acids interfere with the reaction and won’t improve performance.

How long do they keep?
Stored in an airtight container, they’ll keep for several months. Moisture is their biggest enemy.

Are they safe for septic systems?
Yes - they dissolve fully and are used in small amounts.
