Skull Bath Bomb
A fizzy bath bomb for Halloween, these Skull Bath Bombs are the perfect non-candy activity for making or giving away at a Halloween party.
DIY Halloween Bath Bomb Recipe
Ever since the infamous time that I paid $12 for a bath bomb at a store, I’ve been pretty committed to making my own homemade bath bombs.
The first couple times can be a bit tricky as you figure out what the mixture should look like at the different stages, and figure out how to adjust the mixture when it’s too dry or too wet. But eventually, it will become second nature and you’ll be looking for any excuse to make homemade bath bombs.
My daughter and I both love adding themed bath bombs to our baths, and they also make great gifts for friends.
(I actually have people ask me now for homemade bath bombs for their birthday – so I know they are appreciated!)
My daughter wanted to try to make sugar skull bath bombs – which we definitely will try eventually, but these undecorated skull bath bombs were a good start.
A jar full of these would be a fun way to “Boo” a friend, and they make a great non-candy treat for Halloween parties.
You can also make these glow-in-the-dark by adding glow-in-the-dark pigment powder.
The size of these bath bombs will vary based on the size of mold you use. We used a silicone tray that I think is intended for ice cubes or chocolates, but it worked perfect for creating little bath fizzies. My daughter tends to like these mini bath bombs more than the bigger ones because she gets to use multiple fizzies in each bath, extending her fun!
They’d also be great if you have a child or friend who needs to soak their feet occasionally or just enjoys at-home pedicures – it’s the perfect size for a little foot basin!

Skull Bath Bomb Ingredients
- Citric acid – if not ordering online, citric acid can be found at pharmacies, but we got the best deal ordering ours through a home brewery store — it is a food additive, nothing to be worried about. Citric acids serves to neutralize the baking soda in bath bombs and helps your skin absorb the benefits of the other ingredients
- Corn starch – corn starch slows down the reaction time of the bath bomb and helps them retain their scent
- Epsom salts – be sure to purchase quality epsom salts that are 100% magnesium sulfate. Cheaper epsom salts may contain unnecessary additives
- Baking soda – this is the essential ingredient for those fizzy reactions. It also helps exfoliate and is anti-bacterial and anti-inflammatory
- Cream of Tartar
- Water – helps bind the bath bomb
- Coconut oil – reduces the amount of water needed to bind the bath bomb. Any quality/edible oil can substitute
- Essential oils* – optional, pick them for either their scent or suggested benefits
- Mica Coloring or Soap Coloring

How to Make Skull Bath Bombs
In a medium-sized bowl, stir together the citric acid, baking soda, corn starch, and epsom salts.
Add any essential oils or scent desired, along with the dye or mica powder directly to the coconut oil and carefully stir into the bath bomb mixture.
Slowly add you water and check the consistency of the bath bomb mixture – it should have a consistency close to wet sand and hold together when squeezed. (The mixture will start to react with the addition of water, so stir quickly.)
Adjust the coloring and consistency, as needed.
Scoop the bath bomb mixture into your silicone mold and press down.
Allow bath bombs to set for at least 30 minutes or overnight before attempting to remove.
Store bath bombs in a mason jar until ready to use.
