Made with yummy-smelling essential oils, cornstarch, and baking soda, these aromatherapy shower steamer tabs will take your mornings (or night) to a whole new level. I like to make mine in several different scents for different moods and sprinkle them with flower petals for effect. But their real beauty is created when you customise them with any oils, flowers, and colours you like. It’s entirely up to you. They are also a fun activity to make with the kids.

Aromatherapy Blends for Shower Steamers

Here are some of my favourite essential oil combos for the cooler season.

Sinus-Clearing Steamers

  • 5 drops peppermint
  • 15 drops eucalyptus
  • 5 drops thyme

Seasonal Allergy Steamers

  • 10 drops lavender
  • 10 drops chamomile
  • 5 drops helichrysum

Relaxation Steamers

  • 5 drops rose
  • 5 drops ylang ylang
  • 7 drops lavender
  • 5 drops blue tansy

When combined with the steam from a hot shower, these oil blends should have you feeling back to normal in no time. If you don’t want to buy new oils, simply use what you have on hand or invest in carefully selected essential oils that you are sure to use over and over again.


  • Medium-sized bowl
  • Ice cube tray or cake pop mould


  • 2 cups baking soda
  • 1 cup citric acid (available at health food stores or online)
  • ¼ cup corn starch
  • Small amount of witch hazel (or water)
  • 20–30 drops essential oil (I used lavender, rose, and sweet orange, but feel free to choose any of the blends listed in the notes.)
  • Natural food colouring


  • Mix together the baking soda and citric acid in a medium-sized bowl. Just slightly moisten the dry ingredients with water or witch hazel until it clumps when you squeeze it in a fist. That will prevent over-fizzing.
  • Mix your ingredients together (I like to do this part by hand just to make sure everything is well-blended). Add the food coloring and continue mixing until you reach the desired shade. Tightly pack the mixture into an ice cube tray or cake pop molds. Or use a cookie scoop to drop small rounds onto a parchment-lined baking sheet.
  • Allow to dry for 12+ hours, then transfer to a lidded jar until ready to use.


These shower steamer tabs should last about 2 weeks in the fridge. 

Problems with fizzing?

These are essentially bath bombs, so adding too much water or witch hazel too fast will make them fizz up and overflow your mould. Rather than pouring the water directly into the dry ingredients, try putting the water in a spray bottle and lightly misting the top of the baking soda mixture. Use your hands to mix everything together, then lightly spray again. When the mixture just barely holds together like wet sand, you can stop adding water. Ideally, you’ll have hit the sweet spot where the mixture holds together but doesn’t set off an uncontrollable fizz reaction.
