How to Make Eucalyptus Shower Steamers Without Citric Acid: Easy Recipe
Homemade eucalyptus shower steamers are one of my favorite ways to bring aromatherapy into a shower routine. Most shower steamer recipes on my site use only essential oils for scent, but this time I wanted to build the blend around dried herbs instead.
I usually reach for essential oils on their own, but this time I wanted to build the blend around dried herbs instead. This simple shower steamer recipe started out with dried eucalyptus leaves for a clean, herbal scent.
I then added dried lavender buds for a softer, floral note underneath the eucalyptus, and the combination turned out even better than the original.
Together, the two make a scent pairing that works well any time of day, morning or night.
You’ll also notice this recipe skips citric acid entirely. That’s intentional, not an oversight.
Why This Eucalyptus Shower Steamer Recipe Skips Citric Acid
Plenty of shower steamer recipes use citric acid to get that dramatic fizz and bubble when water hits the tablet. I did not add it to these eucalyptus shower steamers for a few practical reasons:
Citric acid reacts the moment it comes into contact with moisture and starts fizzing quickly. Without citric acid, these eucalyptus shower steamers dissolve more slowly in the shower, so the scent releases over a longer stretch of your shower rather than fading quickly.
It also keeps the ingredient list simple and simplifies the process. If your kitchen runs humid or you add even a little too much liquid while mixing, the batch can start fizzing before it ever makes it into the mold.
If you’d rather have fizzier, more classic shower steamers, it’s easy to add citric acid to the basic recipe. You’ll find useful tips in the customization ideas section.
Ingredients to Make Lavender Eucalyptus Shower Steamers
Ingredients
Yield: About 8–10 steamers, depending on mold size
Prep Time: 15 minutes
Dry Time: 24 hours
- ½ cup Baking Soda: The base of the mixture
- ½ cup Epsom Salt: Adds texture and helps steamers hold their shape
- 2 1/2 tablespoons Dried Eucalyptus Leaves: Brings a natural, herbal aroma and a bit of texture.
- 1 1/2 tablespoons Dried Lavender Flowers: Adds a floral note
- 10 drops Lavender essential oil
- 10 drops Eucalyptus essential oil
- 1 ½ tablespoons water: Helps bind all dry ingredients together. Witch hazel in a spray bottle also works well for more control.
- Silicone Mold: This is the one I used, but you can choose any shape you want – rounds, squares, or seasonal shapes for gifting.
Equipment
- Small Food Processor: For grinding the dried herbs to a fine powder.
- Large Mixing Bowl
- Spray Bottle: For adding water or witch hazel a little at a time.
How to Make Eucalyptus Shower Steamers: Step-by-Step
Step 1: Grind the Botanicals
Grind the eucalyptus leaves and lavender buds to a fine powder in a food processor.
The shower steamers will hold their shape better when the herbs are ground down really fine.
Also, a finer grind makes cleanup easier since there’s less residue left on the shower floor.
Step 2: Combine the Dry Ingredients & Botanicals
First, add the baking soda and Epsom salt to a large mixing bowl and stir until evenly blended. Break up any clumps so the mixture stays smooth.
Add the ground eucalyptus leaves and lavender flowers to the dry, clump-free mixture. These botanicals create a natural, decorative look in the finished steamers and release aroma when activated by steam.
Stir gently so they’re evenly distributed.
Step 3: Blend in the Essential Oils
Add the essential oils now. Eucalyptus and lavender work well for this recipe, but you can adjust the scent profile with other oils, such as peppermint or rosemary.
Start with 10 drops of each, mixing well as you go.
Use a wooden spoon or glass stirrer so the oil distributes evenly through the dry ingredients, rather than pooling in one spot.
Step 4: Moisten the Mixture
This step calls for a light hand. Using a spray bottle, spritz the mixture with water or witch hazel a little at a time, stirring constantly.
You’re aiming for a texture similar to damp sand, moist enough to hold its shape when pressed into a mold. Adding too much liquid will prevent it from hardening properly.
Step 5: Fill the Molds
Spoon the mixture into your silicone molds and press down firmly with your fingers or the back of a spoon so each cavity is tightly packed. The tighter the pack, the better it holds together once dry.
Tip: Sprinkle a few extra lavender buds or eucalyptus leaves into the bottom of the mold first for a decorative finish once you unmold the steamers.
Step 6: Leave the Shower Steamers to Dry, then Unmold
Set the filled molds aside in a cool, dry place for at least 24 hours so the steamers harden completely and don’t crumble when removed. Avoid moving the molds during this time, since the mixture can still be fragile. Once dry, gently pop the steamers out of the mold. (See Storage, below, for how to keep them fresh afterward.)
How to Use Eucalyptus Shower Steamers
Place the steamer on the shower floor or a shelf where it will catch a light splash from the water, not the full stream. Too much direct water will dissolve it too fast; too little won’t release the scent well.
Shower steamers rely on hot water and steam to carry the scent into the air, so run the shower on a warm setting and give it a minute after starting before stepping in. Once you notice the scent building, you’re ready to go.
Each steamer is designed for single use. Once it has fully dissolved, rinse away any leftover petals or residue.
Shower steamers are a simple way to add a fragrant touch to an everyday shower.
Troubleshooting Tips When Making Lavender-Eucalyptus Shower Steamers
The mixture is too crumbly
If your mixture falls apart when pressed into the mold, it’s too dry. Add a few more spritzes of water or witch hazel, going slowly. The texture should feel like damp sand that holds its shape when squeezed in your hand.
Steamers crumble when unmolding
If the shower steamers crumble when you pop them out, they either didn’t dry long enough or weren’t packed firmly enough. Let them sit another 12–24 hours, and pack the mixture more tightly into the mold next time.
Uneven texture or lumpy appearance
Lumps can form if dried flowers or leaves aren’t ground finely enough, or if liquid isn’t fully mixed in. Grind the botanicals to a fine powder and combine the dry ingredients well before adding wet ingredients or oils. Mix until the texture is consistent with no dry spots.
Steamers won’t release from the mold
If they feel stuck, place the mold in the freezer for 10–15 minutes. This helps them pop out more cleanly. Silicone molds are easiest to work with since they’re flexible enough to make removal smoother.
Ideas to Customize The Basic Recipe
Experiment with different essential oil blends
Swap lavender and eucalyptus for other favorites or mix and match.
Peppermint adds a cool, sharp twist, while sweet orange or lemon brings a bright citrus note. Try a few different combinations to vary the scent from batch to batch.
Add a touch of natural color
A pinch of mica powder or a little clay, like rose clay or green clay, gives your shower steamers a subtle tint. Beetroot or spirulina powder work well for pastel tones, and turmeric gives a golden yellow. These are natural colorants that won’t affect the texture, and they make a nice touch for gifting.
Experiment with botanicals
Botanicals add texture, visual interest, and fragrance to your shower steamers. Besides lavender and eucalyptus, consider:
- Crushed rose petals for a floral note
- Dried mint leaves for extra freshness
- Calendula petals for a pop of color
Grind each botanical to your preferred texture, from a fine powder to small flecks, so it blends easily and releases scent well when dissolved in steam.
Play with shapes and sizes
Shower steamers don’t have to be round or square. Any silicone mold shape works: flowers, hearts, stars, or seasonal shapes like snowflakes or pumpkins. Smaller molds make quick, single-use steamers for busy days, while larger molds give you a slower-release scent for longer showers.
Add citric acid for a fizzier version
If you’d like the classic fizzing effect, citric acid can be added back in.
Start with about 2 tablespoons for this batch size, and adjust from there based on how much fizz you want.
Keep in mind that once citric acid is in the mix, the fizzing reaction starts the moment the mixture meets moisture, so work a little faster and add liquid in smaller amounts than you would otherwise.

How to Store Lavender Eucalyptus Shower Steamers
Keep steamers in an airtight container to protect them from moisture and air. A glass jar with a tight lid or a plastic container both work well.
Store in a cool, dry place away from direct sunlight, which can fade both scent and color over time. Bathrooms tend to be humid, so it’s best to keep the bulk of a batch elsewhere and bring one or two into the bathroom as needed.
Label containers if you’re storing more than one blend or want to track how long a batch has been made.
Precautions
For shower use only: These eucalyptus shower steamers are formulated for steam release, not for full immersion in bathwater. Use them in the shower only, not in the tub.
Keep away from children and pets: Shower steamers can resemble candies or treats, so store them out of reach.
Follow the recipe amounts: Using more essential oil than called for can overwhelm the scent or affect how well the steamer holds together. Stick to the amounts in the recipe for the best results.
Mind the botanicals: Dried petals or leaves may leave a light residue in the shower. Rinse the shower floor after use to prevent buildup.
FAQ About Eucalyptus Shower Steamers
Why doesn’t this shower steamer recipe use citric acid?
Citric acid creates the fizzing reaction in classic bath bombs, but a shower steamer doesn’t need it. The goal here is a slow, steam-activated release of scent rather than fizzing, and leaving it out also means there’s no risk of the mixture fizzing prematurely while you work.
Why are my shower steamers crumbling?
Crumbling can be due to adding too much or too little liquid, or the tablets not being left to dry long enough. Spritz water slowly and allow at least 24 hours for drying.
Can I use shower steamers as bath bombs?
No. Shower steamers are formulated for steam release rather than full immersion. Use them only in the shower.
Can I make these without dried flowers or leaves?
Yes. You’ll find other shower steamer recipes on my site that don’t use dried botanicals.
How long do eucalyptus shower steamers last in storage?
If stored in an airtight container in a cool, dry place, they’ll keep their fragrance for up to 2–3 months.
