Mid-Winter Warmers: Lavender Bath Bombs

Lavender Bath BombsCan you believe it’s nearly the end of June? Only a month into winter, and I’ve already had my fill of freezing winds and cold rainy days! Well, I don’t mind the rainy days so much, because they give me an excuse to stay in bed and read. :)

Around this time last year I shared a couple of my favourite home made winter cosmetics with you – colloidal oatmeal bath milk and coconut and lavender moisturiser. This year, I have a few more! First up: Home-made Lavender Bath Bombs.

Bath bombs are one of those deceptive things that seem much harder to make than they really are. You can buy all the ingredients from the supermarket, and once you get the process down, there are endless variations of shapes and colours that you can make.

Lavender Bath Bombs


  • 2 Cups Baking Soda
  • 1 1/2 Cups Corn Starch
  • 1 Cup Citric Acid
  • 1/2 Cup Epsom Salts
  • Essential Oil of your choice (I used lavender, hence the name)
  • Vitamin E oil (this is great for your skin, and can be squeezed out of vitamin E capsules)
  • Food colouring (optional)
  • Glitter powder
  • A very small amount of water



  • Spray bottle
  • Mould for forming bath bombs


1.     Combine your dry ingredients (baking soda, corn starch, citric acid, epsom salts and glitter) in a large bowl.


2.     Add a very small amount of water to your spray bottle, along with food colouring and oils. In my first batch, I added the food colouring after the water, and the colours went all clumpy, as you can see in the photos. You get much better colour integration if you add them with the water. Mine looked a little like washing powder with little blue and red specks! 

3.     Moving slowly, and with a mixing spoon on hand, carefully spray the water mixture onto the dry mixture, one squirt at a time. The mixture will begin to fizz, and this needs to be stopped as quickly as possible. Using your spoon, mix each spray of water into the dry mixture quickly and thoroughly. The aim is to get the mixture damp, without activating the normal reaction that bath bombs have to water – that way, they will fizz when you drop them into the bath! This step is easier than it sounds – just go slow, and don’t add too much water at a time. Stop adding water as soon as you can shape the mixture between your hands without it crumbling.


4.     Pack the mixture it into your chosen mould. Simple shapes work well – ice cube trays, muffin trays, etc. Metal works better than silicon, as it doesn’t have any ‘give’ – the bombs are delicate before they dry properly, and the twisting motion of silicon can cause them to fracture. I used a silicon fish mould for some of mine, and many of their little tails fell off. :(


I put some extra glitter in the bottom of these trays so they would sparkle on top :)


5.     You can turn the bombs out onto a clean, dry surface right away, or choose to leave them in the mould until they dry a bit. Either way, they will dry and harden up completely within a few hours, and then they can be used. Voilà! 



I like to list the ingredients when I give these as a gift, just in case anyone has allergies.
