How to Make Bath Bombs – Lavender and Rose

There is nothing more relaxing than a steaming hot bath scented with the heavenly aroma of a lavender and rose bath bomb.

This is one of my favourite bath bomb recipes, and of course the base recipe is entirely customisable to add whatever combination of fragrances you love best.  Watch the video or read on to find out more.


Mixing bowls
Measuring cups and spoons
Fine mist spray bottle
Silicone mat


1 cup Baking Soda
1/2 cup Citric Acid
1/2 cup Epsom Salt
1/2 cup Cornstarch

1 tsp Witch Hazel
3 tsp Extra Virgin Olive Oil
1 tsp Rose Garden Essential Oil
1 tsp Lavender Essential Oil


A few drops of food colouring.


Combine all of the dry ingredients in a large mixing bowl and whisk together.

Slowly add the combined wet ingredients to the dry ingredients until the consistency of the mixture feels like wet sand and will hold its shape when squeezed together. Be careful to not oversaturate the bath bomb mix by getting it too wet too quickly.  

(A tiny amount of fizzing now and then is fine, but any more than that and your mix is too wet, meaning the ingredients are being activated, meaning the bath bombs will not fizz when it comes to using them in the bath.)

Tightly pack your mixture into moulds – I used fillable Christmas baubles but you can also use silicone moulds or aluminium bath bomb moulds.

Leave to dry overnight.

Now you have the hang of it, try experimenting with different fragrances and colours 🙂

To Use

Fill your bath as normal and then drop in a bath bomb.  It will begin to fizz and release its beautiful aroma and colour.

Enjoy a steaming hot, relaxing bath!

After your bath, be sure to give the bathtub a quick wipe down and rinse to make sure no bath bomb colourant remains.  Doing this, I have never had any issues with staining the tub.
