Looking for a new way to bring fragrance into your product lineup? Shower steamers are a fun project to try! Pop one on the shower floor, let a few splashes of water work their magic, and enjoy as the fragrance comes to life in the warm, steamy air.
Unlike bath bombs, these are designed for the shower floor—not bathwater or direct skin use. Start with a small test batch, then tweak your recipe once you've evaluated how it performs.
Tools to gather before you start
- Digital kitchen scale that measures in ounces (ideally to 0.01 oz)
- Large mixing bowl and whisk or mixing spoon
- Silicone molds for shaping your steamers
- Small fine-mist spray bottle for witch hazel
- Gloves and a dust mask suitable for handling fine powders
- A tray or dry spot where the steamers can sit undisturbed
Ingredients you'll need
| Ingredient | Starter batch | Why it's used |
|---|---|---|
| Baking soda | 10.58 oz | Part of the fizzy base |
| Citric acid | 3.53 oz | Reacts with moisture to create fizz |
| Cornstarch | 0.88 oz | Helps the mix hold together |
| Indigo skin-safe fragrance oil | Start with up to 0.14 oz* | Adds your favorite scent |
| Witch hazel in a fine-mist bottle | As little as needed | Helps bind the mixture |
| Suitable cosmetic colorant | Optional, very small amount | Adds a little personality |
* A quick note about fragrance: Every fragrance oil is a little different! The amount you’ll need can vary from scent to scent, so think of the 0.14 oz listed in this recipe as a starting point for your first batch. Before adding scent, check that your chosen fragrance oil is suitable for shower steamers and stays within the maximum permitted usage for your finished product. Category 9 on the IFRA document covers rinse-off bath and shower products. (We chose Category 9 instead of Category 12 as runoff from the shower steamer could come in contact with feet or skin.) If you’re unsure, make your first batch unscented while you practice mixing and misting.
Let's make some shower steamers!
- Mix the dry ingredients.Weigh and thoroughly blend the baking soda, citric acid, and cornstarch. Break up any lumps; avoid breathing in the dust.
- Add approved fragrance.Weigh your chosen fragrance oil only after checking its suitability and maximum permitted level. Add gradually while mixing thoroughly so the scent is distributed evenly. Add a small amount of an appropriate colorant if you'd like.
- Mist—don't pour.Give the mixture a light spritz of witch hazel, stir, and repeat only as needed. The texture should resemble barely damp sand and hold its shape when squeezed. Stop immediately if it starts fizzing in the bowl.
- Pack your molds.Firmly press the mixture into clean, dry silicone molds, packing each one tightly to minimize crumbling.
- Dry thoroughly.Leave in a dry, well-ventilated spot for about 24–48 hours (longer if humid), until completely hard. Gently unmold and store in moisture-resistant, airtight packaging.
- Test before gifting or selling.Evaluate hardness, scent, performance, residue, drainage, and packing stability. Keep good records for each batch and adjust only when renewed safety checks are completed.
How to use your shower steamers
Place one on the shower floor away from the direct water stream but where it can catch occasional splashes. Keep it clear of the drain and out of the direct standing area to help reduce slipping risk. Enjoy the fragrance as it releases, then rinse away any residue.
