Homemade bath bombs are an easy treat that you can enjoy yourself or make as a gift. They are made from common, budget-friendly ingredients most of which you probably already have at home.


·        1 cup baking soda

·        1/2 cup citric acid, anything acidic can damage some countertops (especially marble) so be careful!

·        1/2 cup Epsom salt, recommended to me by my chiropractor to help with sore muscles

·        1/2 cup corn-starch

·        2 teaspoons all-natural food colouring, optional (natural powdered food colouring activates when wet in the tub and will not stain)

·        2 tablespoons coconut oil, melted/warm

·        1 teaspoon water, do not use more than this!

·        10 drops your favourite essential oil, we used Plant Therapy essential oils

·        prizes to go inside - optional! (We used "Magic Grow Capsules" that expand when wet)


1. In a large bowl whisk together the baking soda, citric acid, Epsom salt, corn-starch and (only if using) powdered food colouring. 

2.  In a separate small bowl combine the melted coconut oil, water and essential oils. (You can use peppermint as well, as this would work great with lavender, sweet orange or chamomile.)

3. While continuously whisking, very slowly drizzle the liquid ingredients into the dry ingredients until well combined. The outcome (as pictured below) should be similar to a dry, crumbly sand and should not be a "wet" consistency. Warning: If mixture gets too wet it will activate the fizzy part of the bath bomb too soon!

4. TIGHTLY pack the mixture into each side of the mould then press the two sides together. Ideally let it stay in the mould overnight, then lightly tap around the mould with a spoon to very carefully open and remove bath bomb. Finished product will still be somewhat fragile, so be careful!

5. A Note about Moulds and Gifting: The stainless-steel moulds work best, so that's what can be used with no problems. Bath Bombs (both homemade and store bought) can be fragile though, so you can plan to transfer into same-size plastic moulds for gifting. Alternatively, you can use a hair dryer on shrink wrap baggies made for the purpose of packaging bath bombs.
