How To Create Your Own Shower Steamer
Creating your own shower steamers is a fun, easy, and affordable DIY project that allows you to completely customise the scent, colour, and strength.
Unlike bath bombs, shower steamers are purely about the aroma, so we can focus on the simple base ingredients that create the fizz and act as a vehicle for the essential oil.
DIY Aromatherapy Shower Steamer Recipe
Ingredients:
Baking Soda (Sodium Bicarbonate)
Purpose: The main dry ingredient and base of the fizzing reaction.
Typical Ratio: 1 cup
Purpose: Combines with baking soda and moisture to create the fizz and steam.
Typical Ratio: 1/2 cup
Witch Hazel or Rubbing Alcohol (in a fine mist spray bottle)
Purpose: The "binder." Evaporates quickly to prevent the fizzing reaction from starting prematurely.
Typical Ratio: As needed (Mist lightly)
Purpose: Provides the scent and aromatherapy benefits (use any blend you like).
Typical Ratio: 40–80 drops (for a strong scent)
Optional: Cornstarch (or Arrowroot Powder)
Purpose: Helps slow down the fizzing reaction, making the steamer last longer.
Typical Ratio: 1–2 Tablespoons
Optional: Mica Powder or Food Colouring
Purpose: For colour.
Typical Ratio: A pinch
Equipment:
Glass or Ceramic Mixing Bowl
Whisk or spoon for mixing (gloves are also recommended)
Fine Mist Spray Bottle (filled with witch hazel or alcohol)
Silicone Molds (muffin tins, half-sphere moulds, or simple puck shapes work best)
Air-tight storage container
Step-by-Step Instructions:
1. Combine Dry Ingredients
In your mixing bowl, combine the Baking Soda, Citric Acid, and the optional Cornstarch and Mica Powder. Whisk them thoroughly to ensure there are no clumps and all ingredients are fully integrated.
2. Add Essential Oils
Add your desired essential oil drops (start with approximately 40 and add more if you prefer a stronger aroma). Mix thoroughly to distribute the scent evenly through the powder. You may need to use your gloved hands to break up any clumps that form.
3. Mist and Mix (The Crucial Step!)
This is the most important part for consistency:
Use your spray bottle to lightly mist the mixture with Witch Hazel or Alcohol.
After 5-10 quick sprays, mix the powder thoroughly.
The Goal: Repeat the light misting and mixing until the mixture resembles damp sand or snow and holds its shape when squeezed tightly in your hand. If it starts to fizz significantly, you've added too much liquid.
(Note: The goal is to bind the powder, not activate the fizz. Go slow with the spray! Alcohol or witch hazel is better than water because they evaporate faster.)
4. Press into Moulds
Press the mixture firmly into your silicone moulds. Pack the mixture down very tightly to ensure the steamer is dense and holds together when dry. You can use the back of a spoon to flatten and compress the top.
5. Dry and Harden
Allow the steamers to dry and harden at room temperature in a dry, non-humid location for 24 to 48 hours.
Do not put them in the refrigerator or freezer.
6. Store
Once completely hardened, carefully remove them from the moulds and store them in an airtight container (such as a mason jar) away from moisture and direct sunlight. This helps preserve the potency of the essential oils.
This basic recipe is easy to scale up or down, and you can endlessly swap the essential oils to create a steamer for every mood and need!
