How to Make Your Own Bath Bomb

bath bomb (400x400)I love bath bombs.  Ever since I found them at LUSH, a fabulous organic hygiene and beauty store, I fell in love.  They honestly bring the bath experience to a new level.  Of course, they can get a tad pricey.  After trying a few different recipes I found pros and cons to every recipe, so eventually I combined a few all into one to get the perfect bath bomb.  Of course they don’t fizz quite the same way as the ones at LUSH, but they certainly treat your skin the same way.


  • About 1/8 to 1/4 tbsp. water
  • About 1/2 tsp. of an essential oil of fragrance
  • About 3/8 tbsp. of any light vegetable oils
  • Food coloring
  • 4 tbsp. baking soda
  • 1 tbsp. cream of tartar
  • 2 tbsp. cornstarch
  • 2 tbsp. ground bath salts
  • Molds or plastic wrap


  1. Sift all of the dry ingredients into a bowl.  To grind up the bath salts I used a metal mallet and crushed them down as small as possible.  It is ok if there are still a few large chunks, but try to get them as small as you can.
  2. Whisk your wet ingredients together in a small measuring cup, or quickly pour them directly into the dry mixture.  Use a few drops of food coloring enough that your bath will be the color you desire, but not so much that it will leave a ring in your tub.  I find two drops of red and two drops of blue makes for a really pretty purple, or three drops of green and two drops of blue for a nice teal shade..  Immediately whisk the ingredients together.
  3. If the mixture starts to foam, stir it into a portion of the dry ingredients.  Try to avoid letting this happen by stirring quickly.
  4. At this point the mixture should the consistency of damp sand, moldable but slightly crumbly.
  5. If you have molds, put the mixture in one and let it dry.
  6. If you don’t have molds spread out a sheet of plastic wrap.  Pour the mixture onto the wrap.  Try to mold into a ball shape with your hands as much as possible.  Now wrap it in the wrap and twist the ends shut.  Continue molding and squeezing the ball so it forms the right shape and any dry powder you didn’t get to mold in gets squished in as well. Let it dry for at least half an hour before using.
  7. Unwrap and allow it to fix away into a steaming bath.  The hotter the water the better the reaction.

Once you use one of these you will probably never go back to using a plain bubble bath or just bath salts again.  I enjoy using scents like peach, lavender, or vanilla in mine.  For the oil, cherry kernel is my favorite, but any oil will work as long as it is a light vegetable oil.  At all costs avoid using cooking grade fragrances as they have a high sugar content in them and can cause yeast infections.  Use body safe fragrance oils only.

If you can find powdered citric acid you can replace the cream of tartar with one ounce by weight of that, but it is very difficult to come by so I find 1 tbsp. of cream of tartar works just as well.
