There is nothing quite like dropping a fizzy, fragrant bath bomb into a warm tub after a long day of projects or chasing the kids around. But if you look at the back of a store-bought bath bomb, the list of artificial dyes (like Red 40) and synthetic "parfums" can be a bit overwhelming. That said, if I don;t have time
In our Sustainable Sanctuary, we believe luxury shouldn't come with a chemical footprint.
Making your own bath bombs is surprisingly simple; it’s essentially a kitchen science experiment that results in a spa-like experience. Today, we’re making Natural Pink Bath Bombs. We’ll achieve that beautiful rosy hue using plant-based ingredients and scent them with pure essential oils.
The "Science" of the Fizz
The "magic" happens because of the reaction between Baking Soda (a base) and Citric Acid (an acid). When they are dry, they sit happily together. The moment they hit water, they react to create carbon dioxide bubbles—that’s the fizz!
Ingredients You’ll Need:
1 cup Baking Soda: The base of our bomb.
1/2 cup Citric Acid: The "fizz" factor.
1/2 cup Epsom Salt: Great for relaxing tired muscles.
1/2 cup Cornstarch: This slows down the reaction so the bomb lasts longer.
2 tbsp Coconut Oil (Melted): To moisturize your skin.
1 tsp Beetroot Powder: Our natural pink colorant!
10-15 drops Essential Oil: I recommend Geranium or Lavender.
Witch Hazel in a spray bottle: Our "glue."
Step-by-Step: Crafting Your Bath Bombs
Step 1: Mix the Dry Ingredients
In a large glass bowl, whisk together the baking soda, citric acid, Epsom salt, and cornstarch. Sift in the beetroot powder to ensure there are no clumps. Whisk until the color is an even, pale pink.
Step 2: Add the "Liquid Gold"
Slowly drizzle in the melted coconut oil and your essential oils. Use your hands to "rub" the oil into the dry mixture. It should look like slightly damp sand.
Step 3: The Witch Hazel Spritz
Spray the mixture 2–3 times with witch hazel and immediately mix with your hand.
The Test: Squeeze a handful of the mixture. If it holds its shape like a snowball, it's ready. If it crumbles, add one more spritz. Do not over-wet it, or it will start fizzing in the bowl!
Step 4: Mold Your Bombs
Pack the mixture tightly into both halves of a bath bomb mold. Overfill each half slightly, then press them together firmly. Do not twist—just press.
Step 5: The Wait
Let your bath bombs sit in the molds for about 5 minutes, then gently tap the outside and remove one side of the mold. Let them dry on a soft towel for 24 hours.
Will the Beetroot Powder Stain My Tub?
One of the most common questions about using natural colorants like beetroot is whether they will leave a pink ring behind. Unlike synthetic dyes, which can "stain" porous surfaces, beetroot powder is water-soluble.
The Oil Buffer: The coconut oil in this recipe acts as a carrier, keeping the color suspended in the water rather than letting it soak into the porcelain.
The "Limescale" Factor: If your tub has a rough texture due to Hard Water Build-Up, the pink color might "catch" on those mineral deposits. For a perfect experience, give your tub a quick scrub before your bath!
Easy Clean: A simple rinse with the showerhead after your bath is all you need to clear away any residual pink dust.
Pro-Tips for the Perfect Bath
The Floral Touch: Place a few dried rose petals in the bottom of the mold before adding the mixture.
Storage: Keep your bath bombs in a glass jar with a tight lid. Humidity is the enemy of the fizz! (If your bathroom is extra steamy, see our guide on Bathroom Humidity Control).
