Mr. Clean song for kids
is the perfect complement to this super fun kids bathtub crayon recipe activity!

So, what are you waiting for?  Let’s make Bathtub Soap Crayons!

Craft supplies you will need:

  • Clear glycerin soap base cut into cubes
  • 3 or more soap color dyes (or food color dyes)
  • Essential oils in your favorite smells (optional)
  • Glass measuring cup for melting soap
  • Spoons for mixing colors and fragrances
  • Ice cube trays or round crayon molds

Craft instructions:

Separate the soap base cubes; one pile for each soap color dye.

Have the children place the soap cube for the first color in a glass measuring cup and melt in microwave in short bursts.

Once melted, have the children add soap color a drop at a time, mixing well after each drop until you get the color right.

Then, add a couple of drops of essential oils and mix well.

Next, have the children carefully pour the color soap into ice cube trays.

If you see any air bubbles on the surface of the soap, spray it with rubbing alcohol.

Have the children repeat the same soap crayon making process with the rest of the colors.

After that, allow the soap to set until it is firm. This could take anywhere from 30 minutes to a few hours.  When the soap is close to firm, feel free to place the soap in the freezer to speed up the hardening process.

When ready, have the children pop the soap crayons out of the trays.

And Voila! We just made a Homemade Bathtub Crayon Recipe with the kids!

    Awesome idea! One question though – does the food color in the crayons end up on their hands or stained on the shower walls? We will most definately be making these – probably by the weekend!!!

    Hi Pati!

    We did not have any staining, so you should not have any either. Go for the darker colors because they show up best. Have fun and enjoy!

    all the best,
    Sherry + Wendy @ Kiboomu

  10. Elizabeth says:

    Where can you find soap dye locally – does Michaels or Joanns typically carry it? Also, if you use food dye, will it stain, or is it such a small amount to add color that it won’t?

    Definitely want to try this for Christmas gifts!

  11. wendy says:

    Hi Elizabeth,

    We live in Canada, and I found it at Omar Des Serres. Which means YES, you would definitely find it at Michaels. Also, I have used food dye, and it does not stain. Please note, you have to use DARK colors and a lot of coloring for it to show up on the bathtub. But it comes off easily, and if fun to make (for sure!).

    All the best,
    Wendy & Sherry @ Kiboomu

  12. Faith says:

    Where do you get the molds like the one in the pictures?

  13. wendy says:

    Hi Faith,

    Actually I got those at the Dollar Store. They are really ice cube trays! They are for water bottles,
    I believe. But I fill them as full as can be, and then they make an almost round crayon shape.
    Are you going to try and make them? If you do, let us know how they turn out :)

    All the best

  14. Lyndsey says:

    Where did you get the soap you used for these? Any particular brand? I’ve tried a few other tutorials and haven’t had any luck with them turning out correctly. Thanks!

    Hi Lyndsey,

    We are from Canada, so I bought my clear glycerin crayons at Omer des Serres. But I am SURE you can buy clear glycerin soap at Michaels. It comes in a block, cut up into about 36 – 50 squares.

    I take 2 squares at a time, put them in a measuring cup, and put them in the microwave for about 15 seconds per spurt – until they are melted. Then I add the food coloring (making it dark so it shows up). Then I pour it into whatever molds I have.

    I don’t worry about any bubbles. I just pour it really slowly! LOL!

    Good luck, and let me know if this helps :)

    Wendy & Sherry @ Kiboomu

  17. Faith says:

    It worked perfectly!

  18. Megs says:

    I made this recipe, is there a special king of soap or dye that can be used to actually show the crayon strokes on the tub? I can’t get mine to show up very well with using food dye!!!

  19. Emily says:

    This is such a good idea! I tried making these and had no luck with the color actually showing up. I feel like I used quite a bit of dye. Any suggestions?

  20. Becky says:

    So I made these cuties as Christmas presents for my nieces and nephews. They look great – BUT… they don’t work! No joke, the look EXACTLY like the picture, but they leave NO color behind when they write on the tub. What went wrong?!?

  21. Lauren says:

    none of the colors showed up on the tub, even the dark ones. any suggestions?

  22. sherry says:

    More food coloring. We found that the dark colors write best. The dark colors write very very lightly, but they show up the best. The kids just like to write with them, so we’re lucky. They don’t seem so concerned that they don’t show up well. We’re still on the lookout for the perfect homemade recipe! Hope 2012 brings it to us!!!

  26. Tiffany says:

    I wonder if something like the Wilton frosting die would work. They tend to be darker in color and would take far less to color the the bath crayon. I think I might try it!

  27. sherry says:

    Tiffany, let us know if it works!

    all the best,
    Sherry + Wendy @ Kiboomu

  28. Tiffany says:

    It worked! I used the Wilton frosting dye and the colors wrote very dark in the bath tub. I did use the white glycerin because I was out of clear. The only problem I had was that I did have to spoon out a clump of dye that did not disolve. So I tried to disolve the dye in water (food coloring consistancy) then mix in the soap. The ones I did this for did not write at all on the bath tub.

    I can’t wait to try this with the kids. I’ll try the Wilton frosting dye that someone else suggested, and will let you know how it turns out. Fun activity for a Winter weekend, and I plan to package them up for kids’ birthday gifts for the remainder of the school year ;)

    One of our readers, Tiffany, used Wilton frosting dye and said it worked great!

  33. sherry says:

    Hi Becky!

    For us, the darker colors works, but they write very lightly. The kids do not seem to mind. Having said that, one of our readers recently suggested using Wilton frosting dye, so you may want to try that!

    all the best,
    Sherry + Wendy @ Kiboomu

    Happy 2012!

    Fabulous. If you took a photo, send it to us. We would love to post it!

    Hi Megs!

    One of our readers recently suggested using Wilton food dye for the Bathtub Soap Crayon craft recipe, so you may want to go ahead and try that.

  36. sherrie says:

    i have never made these crayons, but know my kids would love them!!! I do make them bath paint tho, and they LOVE it!!! it works FABULOUS!!! I use baby wash (usually the walmart brand… it less then $2 for a giant bottle of their version of head-to-toe) mix it with cornstartch, to desired thickness… and add wilton paste food coloring!!! DD has sooo much fun with this!!! and i make TONS!! for less then $4!!! (i dont count the cost of dye, since i decorate lots of cakes and have tons of colors on hand already)

  37. sherrie says:

    can i melt down ivory soap, and use that???

  38. wendy says:

    You can grate the soap, and then add hot water and form into a ball. But they won’t have the same appearance or coloring ability as the glycerin bathtub soap crayons. But your suggestion is another easy and fun way to make crayons, for sure! Let us know how it turns out!

    All the best,
    Wendy & Sherry @ Kiboomu

  39. sherry says:

    Hi Sherrie!

    Happy 2012.

    Your bath paint recipe sounds great. Thanks for sharing it with us.

  40. May says:

    Hi! Thank you for the instructional post, and I really appreciated your readers leaving handy comments as well! I finally got around to trying it, got the clear glycerin soap, had some liquid food dye and also picked up some violet Wilton’s icing dye to test it out. I had very high hopes for the icing dye since it looked so intensely vibrant. I made 4 colors. My soap was from Michael’s and was in a 9-lb bar, and pre-’scored’ in little ice-cube shapes. I used 2 cubes per color. I used a tiny half-a-pinky scoop of the icing dye gel and it made the soap very very dark, and almost opaque. Then for the other colors, I used blue (8 drops), red (16 drops), and green (10 drops). The blue performed outstandingly. The green was second best, rather light on the walls but fantastic on the hands.. The red was still very faint. The violet broke my heart. NO color left on the walls at all. I don’t know if I really needed to use a whole lot more or if Wilton has perfected a deep icing dye that will NOT leave your tongue looking like an alien appendage. I’ll add tons when I make another batch and see how that will turn out. I will also be adding more coloring for the other colors for added punch. This was fun to make!

  41. Angie says:

    To mold, I used milk shake straws (or bubble tea straws)… I folded one end of the straw and taped it shut. After filling them with the melted glycerin, I just put the straws in a glass to set. After they set, I used a knife and cut the straw off. VERY easy. (My colors don’t show up in the tub either… but I think my daughter will still enjoy them)

  44. Amanda says:

    I don’t know if it will help in the crayons or not, but a suggestion to try. I used to make bath paint using store brand baby wash and kid-safe, washable craft paint that I bought at Hobby Lobby. The color was great and didn’t stain. Maybe the kid’s paint would work as a colorant for the bath crayons?

  45. sherry says:

    Hi Amanda!

    Happy 2012.

    Thank you so much for sharing the tip. Will definitely look into it!

    all the best,
    Sherry + Wendy @ Kiboomu

  46. shirley says:

    for those who have tried this recipe unsuccessfully, is there any reason why they couldn’t melt their crayons back down again and add more color? rather than waiting to make another whole batch? just a thought….maybe the first batch can still be salvaged. :)

  48. Valerie says:

    I made this recipe this evening with my kids after seeing it on Pinterest. We had a fantastic time! I didn’t have any crayon shaped molds (or actually any molds at all) so i gave each of the 4 children a piece of parchment paper. i have a box of 101 plastic cookie cutters. we poured the soap into the cookie cutter and held it down tightly to the parchment paper for a minute or less until it solidified a little bit. then i put a freezer pack from the kids lunch boxes on top of it for a couple of minutes. then it just popped out! it didn’t write dark on the tub, but it did write. the best part was, when the little girls were in the bath with their soap, it showed on their body, where they did and did not wash! i was concerned it would stain them from the food coloring, because we made them quite dark, but it all washed off quite well. Thank you so much for the wonderful idea! Sincerely, Valerie Stewart (Happy Mother of 4)

    Hi Valerie!

    We love when a recipe comes together! So glad your girls had fun with the crayons.

    Thanks so much for sending us the breakdown of your recipe.

    Let us know if the violet works next time around. Such a pretty color.

    Glad you had fun making them!

    Sherry + Wendy @ Kiboomu

  53. sherry says:

    Hi Angie!

    We never thought of milk shake straws. How interesting! We have only been able to get the dark colors to work, but like your daughter, the kids do not seem to mind. We’re going to try Wilton products the next time we make the crayons since everyone seems to be having luck using that!

    all the best,
    Sherry + Wendy @ Kiboomu

  54. Alissa says:

    Beware, wilton dyes stain just about everything they touch

  55. Michelle says:

    You can find all soap making supplies at Hobby Lobby. For relatively cheap too

  56. Robin says:

    I have five grandbabies under the age of 6…so I have to try this! I was thinking about using Candy Molds to make these with? With Easter coming up….thought about Easter Eggs. Great for their Easter Baskets!

  57. sherry says:

    Hi Robin!

    Candy Molds sounds like fun! Let us know how it all turns out. Just make sure your grandbabies don’t eat the them! :)

    all the best,
    Sherry & Wendy @ Kiboomu

  58. Tani says:

    try using mr.clean magic eraser for the old ones :) because these are soap based they should wash off though! good luck and have fun :)

  59. wefarm2 says:

    I can’t wait to try your recipes! I make bath paint with shaving cream (bought on clearance for a quarter) and food coloring! My grandson LOVED painting up the tub with both paint brushes and his hands :) The shaving cream cleans up most of the mess. Could you use cardboard rolls as a mold for the soaps???? Just brainstorming :)

  60. sherry says:


    Feel free to give the cardboard rolls a try and please let us know if it works!

    all the best,
    Sherry & Wendy @ Kiboomu

  61. Shannon says:

    Went to the Dollar Store today and found the ice cube molds for water bottles….they do 10 in each mold and comes with 2 molds for $1….so 20 soap crayons for $1….what a bargain! My girls are having a BLAST making these right now…even my 12 year old thinks this is the coolest thing ever!

  62. Lisa says:

    Just wanted to say I made these this weekend for my 17 month old, and they worked perfectly! I read all the comments and added a ton of food coloring. Thanks so much for the idea!

  63. sherry says:

    Hi Lisa!

    Thanks for writing and letting us know. Hope your 17 month old had a blast.

    I just tried this and re blogged it on my blog, I’ve also got a recipe for bubble bath, that works, bath paint, body glitter, “jelly” bubble bath, and they didn’t stain our skin or tub. I love your recipe and so do my kids! come check us out!
