Roses smell even sweeter the second time around if you make them into bath bombs.

What to do with those beautiful petals when they've fallen from the rose? Why make bath bombs, of course.


Sweet Dreams: Choose These Rose Types for Fragrance 8 photos

“The recipe for bath bombs in quite simple; the technique is the hardest part,” says Ashley DuFresne of Seri’s Soaps. “But with some practice they are a wonderful DIY project,” says DuFresne.

  • 2 parts baking soda
  • 1 part citric acid
  • Fragrance of your choice
  • Moisturizing oils (avocado oil, coconut oil, sweet almond oil, etc.)
  • Sea salts or Epsom salt (optional)
  • Rose petals or other flower petals
  • Color (see below)
  • A few spritzes of witch hazel
  • Circular mold


Mix the ingredients together and place them in the mold. Let them sit for a few minutes to give them time to harden, pop them out and let them dry for 24 hours.

A few tips:

Don’t use too much witch hazel; a few spritzes is all you need. Otherwise it will make the bath bomb react too early and it will become “a wet glob,” says DuFresne. “Aim for the consistency you would look for when building a sand castle.”

If using salts, use a small amount. Too much salt will prohibit the bath bomb from bonding and it will be brittle.

If you want to color the bath bomb, DuFresne recommends natural pigment colors. “They work great and will tint the water without staining the tub,” she says.

Add rose petals directly into the mix or sprinkle them into the mold and press the bath bomb mix on top.
