Solid bubble bath, also known as bubble bars in some high end soap shops, is super easy to make and gives you loads of fluffy bubbles. If the stress of the holiday season is getting to you, put aside the shortbread dough, whip up a quick batch of these solid bubble bath bars and call a Christmas time-out in your tub.

Things You'll Need

Go shopping for your ingredients. Some you may already have in your pantry, and some you can pick up at your local grocery store. The rest can easily be purchased online at a soap making supply Web site (see below).

You will need a clean, clutter free work space to make your handmade solid bubble bath. The kitchen counter or table works perfectly.

Wash your hands thoroughly. You will be using them to mix and mold the solid bubble bath bars and you don’t want to transfer bacteria from your hands onto your handmade Christmas goodies. It’s also recommended to wear thin kitchen gloves if you’re worried about staining your hands when they come in contact with the liquid colorant.

Mix all of your dry ingredients into a large metal or glass mixing bowl. Using your hands as sifters, thoroughly blend the dry ingredients together and remove any lumps.

Add your liquid colorant. Don’t add too much as even high quality soap colorant can stain tubs and skin if used in excess. Instead, aim for a light to medium pastel shade. It’s always nice to try and match your color with the fragrance you plan on using. For instance, if you’re making Lavender scented bubble bath, use a little purple colorant.

Add your fragrance. Start with approximately 25 drops of fragrance oil from an eye dropper and mix the “dough” well with your hands to incorporate the color and fragrance. Give your solid bubble bath a sniff test and add a little more fragrance if the scent isn’t strong enough for you.

The last ingredient to be added is the liquid glycerin. Pour this in slowly, small amounts at a time, and mix thoroughly until the mixture holds together in your hand (similar to dough).

You are now ready to transfer your solid bubble bath to a loaf pan. Press the bubble bath dough firmly into the loaf pan to help the mixture hold together better while drying. Let the dough sit in the loaf pan for approximately an hour to allow it to begin to set up.

After an hour you can carefully remove the bubble bath loaf from the mold. If it is too dry and crumbly return the mixture to the bowl, add more liquid glycerin and mix thoroughly. Return to the loaf pan to set up for another hour.

Once the bubble bath loaf is firm enough you may begin to cut it into small cubes or slices. Use a sharp knife or a dough cutter and cut into either thin bread-like slices or into cubes approximately the size of a standard ice cube or a little larger.

Place these pieces on a wax paper lined cookie sheet and allow them to cure and harden overnight.

Once the solid bubble bath bars have hardened, they are ready to be wrapped. Use clear cellophane for wrapping to protect the solid bubble bath from humidity. Always store your solid bubble bars in a cool, dry place. Try to use within two to three months for best results.


  • Giving your bubble bath bars as gifts? Wrap small chunks of the solid bubble bath in square pieces of colored cellophane and tie each end with thin ribbon or string to make them look like wrapped candy.
