Homemade bath bombs are one of my favorite simple, non toxic treats. Store-bought ones are often full of synthetic fragrance and dyes, but these use just a few clean ingredients.
These are so fun to have and make. The formula is a little picky to get the right consistency. If you get them too wet they “grow” they will still work so do not throw them away but they just do not look as pretty.
So it might take a couple of times to get it right. But after you do they will last a long time and you can scent them in so many ways!
I make mine pretty small and leave them unscented when I make them so I can add what oils and scents I am feeling at the time. I do not add herbs because we have a jetted tub and you do not want those herbs going through there. But add what works best for you and make them your own!
I would suggest starting with half a batch and play with the consistency till you get the hang of it. Half a batch will make you 6-8 smaller balls.
Bath Bombs
- 2 Cups Baking Soda
- 1 Cup Citric Acid
- 3/4 Cup Corn Starch
- 3/4 Cup Unscented Epsom Salts
- 3 Tablespoons Bentonite Clay
Add Ins:
- Any dried herbs
- Essential Oils for scent
Add all the ingredients into a mixing bowl and mix thoroughly. Get a spray bottle and fill with witch hazel, spray a layer on top and then toss. Repeat this until its like sandcastle wetness- or till you can grab it and it clumps together. Remember! Not too wet or after you shape them they will grow. So the dryer they are the better, you just want them to barely stick together.
To form them you can use a small muffin tin or if you want them to be round see below
Why Make Your Own Bath Bombs?
- No synthetic fragrance or dyes. You control exactly what goes in.
- Epsom salt is a source of magnesium and a classic for relaxing tired muscles.
- Baking soda softens the water and leaves your skin feeling smooth.
- They make great gifts for birthdays, teachers and the holidays.
- They save money. One batch costs a fraction of store-bought bath bombs.
How to Use Your Bath Bombs
Fill your tub with warm water, add your favorite essential oils to a bath bomb, and drop it in. Sit back and watch it fizz! Soak for at least 20 minutes to give the Epsom salt time to work and let your body relax. Light a candle, put on some calming music, and make it a little moment just for you. You deserve it.
Scent Ideas
- Relax: lavender and cedarwood
- Uplift: wild orange and peppermint
- Breathe easy: eucalyptus and lemon (for adults)
- Romance: rose or ylang ylang
Add about 2 to 3 drops of essential oil per bath bomb when you use it, or mix 15 to 20 drops into a full batch.
Bath Bomb Tips and Safety
- Store your bath bombs in an airtight glass jar so humidity does not set them off early.
- Wear gloves if you have sensitive skin, since citric acid can sting small cuts.
- Keep them away from little ones who might think they are candy.
- Use gentle oils for kids, and skip strong oils like peppermint and eucalyptus for babies and toddlers.
- Your tub may be slippery after a bath bomb, so be careful getting out.
