Bath Bomb Recipe – Summer Swim

This bath bomb recipe lets me take a summer swim in the middle of winter. Well, it’s a swim in my bathtub, but still…

You see, I grew up near the Atlantic Ocean in Massachusetts. My childhood was full of surfing the salty waves, finding sea creatures in the tidepools and digging my toes into the gritty sand. Now I live in Texas, far from the ocean. But I’ve created a bath bomb to help me recreate the joy I used to feel during a summer swim.

What I remember clearly is how the ocean waves leave a frothy layer of bubbles on the sand each time in recedes back into the sea. I also remember how the sunshine reflected and refracting in shiny bits off of the ocean’s surface, too.

Follow this bath bomb recipe and your tub will be full of frothy bubbles. What’s more,  you will see the glittery sunshine, too. That’s why I call this bath bomb “Summer Swim.”

The Secret to Making Bubble Bath Bombs

This recipe uses SLSA, a substance that makes your bath bombs foam and bubble. But it can also make them crumbly. So it’s extra important with this mixture that you get the consistency just right before you pack it into the mold.

SLSA is a very fine powder, so you may want to wear a mask to avoid breathing it in. Or at least make this bath bomb in a room with an open window

I highly recommend making an embed to place in the center of this bath bomb. With the embed, you’ll get extra fizz and spin to create the full ocean effect.

When you add the mixture to the mold, you’ll definitely want to bury the sea creature in the mixture. This way the sea creature will stay stuck in the bath bomb once it dries and you remove it from the mold. Once you remove the bath bomb from the mold, you’ll use a paintbrush to uncover the sea creature.

Buried Sea Creature
After I take the bath bomb out of the mold, I use the paintbrush to gently uncover the buried sea creature.

This recipe makes 3 large bath bombs with ornament mold or 5 medium bath bombs (will vary depending on size of your molds)


  • Rubber gloves
  • Bath bomb molds in spherical shape – I like the plastic ornament molds
  • Mixing bowls
  • Microwave safe bowl (to melt down coconut oil)
  • Paintbrush
  • Spray bottle (for witch hazel)
  • Face mask
  • Measuring cup

testing the consistency of the mixture
This bath bomb mixture passes the consistency test because when I squeeze it in my fist, it holds its shape and doesn’t crumble.
