Homemade Natural Bath Crayons

DIY Homemade Natural Bath Crayons!

I’ve been wanting to experiment with homemade bath crayons for a while now and am excited to say I finally got around to doing it! They didn’t turn out as “pretty” as I’d hoped for, but they work, and they aren’t full of toxic chemicals like the ones you might find at your local “Target” or “Walmart”. Next time I’m going grate the soap flakes a bit finer, and try to find some cute molds at the thrift store, but overall I’m quite pleased. Oh and the best part- you only need two ingredients and a bit of hot water to make them!


  • Grated Castile Bar Soap- 1-2 bars depending on how many crayons you’d like to make (for just one crayon in each color 1 bar of soap is plenty).
  • Natural  Food Coloring- Several drops for each color bath crayon you wish to make. I prefer the India Tree brand, you can purchase them for about $15 at AND get $5-$10 off with coupon code: VFG295 if it’s your first order!
  • Hot Water
 Natural Bath Crayon Recipe
  1. Grate your bar of soap- I used our cheese grater and it worked well. However, instead of using the side with the biggest holes, I’ll definitely be using the side with the “second biggest” holes next time! One bar of soap should equal about one cup of grated soap.
  2. Divide your grated soap into bowls-  One bowl for each color you want.
  3. Add a bit of hot water to each bowl- Add a few drops at a time and use a spoon or fork to mash it all together until you reach a good consistency and all of the pieces are incorporated. (If it’s too sticky or watery to handle you’ve added too much water, no big deal though, just add a bit more soap, you’ll live, I promise!)
  4. Add a few drops of food coloring to each bowl until you reach your desired color- This can be a great opportunity to teach little ones about mixing colors! Start with Red, Yellow & Blue food coloring and mix to create orange, purple and green. (Red + Blue= Purple, Red + Yellow= Orange, and Yellow + Blue = Green)
  5. Mold into “crayons”- You can simply use your hands to mold the soap into crayons like I did, or use a soap mold, candy mold or even cookie cutters to shape your bath crayons. There are some really cute crayon molds on Etsy too! Once you’ve molded your bath crayons one way or the other place them in the freezer overnight- if you’ve opted to use a mold, leave them in the mold until you remove them from the freezer.

 I made some round shapes too, but must admit I’ll definitely use some sort of mold next time around! Never the less, the kidlets LOVE them- natural homemade bath crayon mission complete!
Now for a quick little bonus…
Homemade Natural Bubble Bath Recipe

Here’s Our Favorite Homemade Bubble Bath Recipe:

  • 1 Cup Liquid Castile Soap
  • 3/4 Cup Water
  • 1 Teaspoon Glycerin
  • 6 Drops Essential Oil(s) Of Choice
Mix all of the ingredients together. Store in a container with a lid, you can upcycle an old shampoo container if you’d like. Castile soap is made from natural, plant-based oils such as olive, coconut, and jojoba. Glycerin attracts moisture to the skin, leaving the skin soft. Essential oils that you can add which have a relaxing and calming affect are chamomile, lavender, and neroli.

  1. I can’t believe I never thought to make my own bubble bath! I’m always on the lookout for natural bath products for my little one, but they tend to be pretty pricey. I’m definitely giving this a try. (The Bath Crayons, too.) My daughter likes to stick her face into the bubbles… do you know if these bubble bath ingredients would irritate your eyes? Thanks for sharing!

    I can’t wait to try these! where do you get your soap and glycerin?

  3. librarypat says:

    Thank you for the recipes. What a great idea. It is easy to make and a fun project to do with the children. It is easy enough to do with little ones and something older children can make on their own to give as a gift for a younger relative or friend. It is a product scouts, 4-H, or other youth groups could make (using molds) to sell as a fund raiser at a yard sale or flea market. A net scrubby, the crayons, and bubble bath would make a nice little Earth and child friendly gift basket.

    Now I feel like I should be stocking up on castile soap. ;)

  5. I love this idea! I think I might make a whole bunch as Christmas gifts next year. :)
