Fizzy bath salts provide all the fun of a bath bomb but are easier to make. With this recipe, you’ll have a fizzy, bath-bomb-style bath, but you don’t have to mold the bath bombs. It’s much faster than making bath bombs and provides a similar result.

What are fizzy bath salts?

Fizzy bath salts, or fizzy bath powder, have similar ingredients to bath bombs, but they don’t require the careful mixing and shaping that bath bombs do. Because of this, they are faster to make than bath bombs but give the same result.

Instead, they are mixed in a bowl, stored in a glass jar, and used by the scoopful for a fun, fizzy bath experience.

I love a good shortcut, and that’s why I love this recipe. It’s like a bath bomb with less work. Yesssss.

DIY Fizz bath

What makes them fizz?

Citric acid and baking soda are the primary fizzing ingredients in fizzy bath salts. The fizzing effect is activated when those ingredients are wet, so it’s essential to keep the bath salts dry until you’re ready to use them.

Make sure when you’re mixing in the calendula oil, you do so slowly so that you don’t activate the fizz too early.

Why Calendula?

Calendula is a wonderfully calming, soothing, and gentle plant that’s great for delicate skin. This recipe uses homemade calendula oil and dried calendula petals. It has a slightly earthy smell from the calendula but is essential oil-free and fragrance-free.

Calendula oil is carrier oil (in this case, sweet almond oil) that has been infused with calendula petals. It is not an essential oil, which is typically distilled through a more complex process. It is an herbal-infused oil and has lots of uses.

If you have sensitive skin, this is an excellent recipe for you. Epsom salts and baking soda provide calming effects, and calendula oil and petals soothe sensitive skin.

Calendula is also known for its skin healing properties. It is a beautiful addition to a relaxing bath.

Dried Calendula flowers

Do I have to make my calendula oil?

Nope! You can purchase high-quality calendula oil to use in this recipe. This organic calendula oil is a good choice, although it is infused in olive oil instead of almond oil.

Olive oil is most commonly used for calendula oil infusions, but I prefer almond oil because I like to use it in various DIY recipes. The olive oil infusion will still make a nice fizzy bath salt in this recipe.

Calendula oil

If you’ve never tried homemade calendula oil before, I hope you’ll consider it! It’s straightforward to make, has lots of uses, and you’ll already have the calendula petals to use in this fizzy bath powder recipe, so why not give it a try?

Storing Fizzy Bath Salts

Your homemade bath salts will keep for up to 3 months in an air-tight container. Wide-mouth mason jars are great for this, or try re-using a container you would otherwise throw away!

Make sure to keep water out of the container since the fizzing action is activated by water. Keep these bath salts DRY until ready to use.
