How to Make DIY Bath Bombs at Home

Bath bombs are a fun and easy DIY project that turns your bath into a relaxing, fizzy experience. Making them at home allows you to customize scents, colours, and ingredients. This step-by-step guide will show you how to create your own bath bombs with a foolproof recipe and helpful images.

Ingredients You'll Need

• 1 cup baking soda (sodium bicarbonate)
• ½ cup citric acid (anhydrous)
• ½ cup Epsom salt (optional - do not include if you are in a humid climate)
• ½ cup cream of tartar
• 3 tablespoons coconut oil (melted) or another carrier oil
• 1 teaspoon water or witch hazel
• 1 teaspoon essential oil (lavender, peppermint, or your favourite scent)
• 1 teaspoon mica
• Soapmaid's Plastic Bath Bombs Moulds 

Step-by-Step Guide

Step 1: Mix Dry Ingredients

In a large mixing bowl, combine baking soda, citric acid, epsom salt, cream of tartar and mica. Use a whisk to evenly mix them together.
👉 Why? Baking soda and citric acid create the fizzing reaction, while Epsom salt soothes the skin, and cream of tartar helps harden and hold everything together.

Step 2: Mix Wet Ingredients

In a small bowl, combine coconut oil, essential oil, water (or witch hazel). Stir well to blend the ingredients.

Step 3: Combine Wet and Dry Ingredients

Slowly add the wet mixture to the dry ingredients a little at a time, whisking constantly to prevent fizzing. Continue mixing until the texture resembles damp sand and holds together when squeezed.

Step 4: Fill the Moulds

Pack the mixture tightly into your bath bomb moulds, pressing firmly. If using two halves of a mould, overfill slightly before pressing them together. Let them sit for a few minutes before gently removing from the mould.

Step 5: Let the Bath Bombs Dry

Place the moulded bath bombs on a tray or parchment paper and let them dry for 24 hours. They will harden as they dry.

Step 6: Enjoy Your Bath Bombs!

Once fully dried, store your bath bombs in an airtight container. Drop one into your bath, watch it fizz, and enjoy a relaxing soak!
