Everything you need to make your own bath bombs at home, minus the guesswork. This kit pairs three mold sizes with pre-measured core ingredients, so you can go from mixing bowl to bath-ready in one afternoon — no sourcing a dozen separate ingredients required.

Available in Lavender or Peppermint Castile soap, which does double duty: it binds the mixture and scents your bath bombs naturally, so there's no need to buy essential oils separately.

What's Included

  • Set of 3 bath bomb molds (small, medium, large)
  • Baking Soda - 500g
  • Citric Acid - 500g
  • Epsom Salt - 500g
  • Castile Soap - 250ml (choose Lavender or Peppermint)
  • Stainless steel tablespoon measure

What You'll Need to Add

Just one pantry staple: cornstarch, available at any supermarket. Everything else is included in the kit.

Why You'll Love It

The three mold sizes let you make a range of bath bombs in one batch — small ones for gifting or travel, medium for everyday use, and large for a proper soak. The Castile soap comes pre-scented, so there's no separate essential oils or fragrance blending to figure out. The stainless steel tablespoon means your measurements are accurate and repeatable every time, and it's a keeper for the kitchen once your bath bomb days are done. With 500g of each core ingredient, you've got enough to make multiple batches, not just a one-off trial.

How It Works

Mix the baking soda, citric acid, Epsom salt and cornstarch, then slowly work in the Castile soap until the mixture reaches a wet-sand texture. Pack it firmly into your chosen mold, twist and release, then leave to air dry for 24 hours. That's it — homemade bath bombs, ready to gift or use.

Perfect For

First-time bath bomb makers, gift-giving (birthdays, Mother's Day, teacher gifts, party favors), and anyone who wants a natural, low-fuss alternative to store-bought bath bombs.

Scent Options

Lavender — calming and floral, ideal for winding down before bed. Peppermint — cool and invigorating, great for an energizing soak.

Note: Cornstarch is not included and can be picked up at your local supermarket.
