What You’ll Need to Make Bentonite Clay Bath Soak
Base Recipe
- ¼ cup Bentonite Clay Powder
- ¼ cup Magnesium Flakes (or Epsom Salts)
- ¼ cup Calendula Powder
- ¼ cup Baking Soda
Optional Add-Ins
- ¼ cup Ginger Powder (adds a warming, tingling sensation — see notes)
- 10–15 drops Essential Oils (scroll down for best options)
- ½ cup Apple Cider Vinegar (added directly to the bath, not the mix)
Equipment
- Glass or Ceramic Mixing Bowl (avoid metal)
- Wooden or Plastic Spoon (avoid metal)
- Airtight Glass Jar for storage
How To Make Bentonite Clay Bath Soak
Step 1: Mix the Dry Ingredients
Add all your measured dry ingredients – bentonite clay, magnesium flakes, calendula powder, and baking soda – into a glass or ceramic bowl.
Important Note: Avoid using metal bowls or metal spoons when working with bentonite clay. Metal can interfere with the clay’s natural charge and reduce the quality of the finished product.
Stir everything together thoroughly with a dry wooden spoon until the mixture is uniform and well combined, with no visible streaks or pockets of individual ingredients.
The finished mix should have a uniform, slightly golden-beige color. The calendula gives it a warm color, which is completely normal.
If you’re including ginger powder, add it at this stage and mix it in well.
Step 3: Add Essential Oils (Optional)
If you’d like to add essential oils, now is the time, but with one caveat.
If you’re making a large batch to store, it’s best to add your essential oils only when you’re ready to use a portion, rather than mixing them into the whole jar.
This keeps the scent fresh and prevents the oils from degrading the dry mix over time.
If you’re mixing a single-use batch, go ahead and add 10–15 drops now and stir through until evenly distributed.
See the essential oils section below for scent suggestions based on the kind of soak you’re looking forward to indulging in.
Step 4: Transfer to a Glass Storage Container
Spoon your finished bath soak powder into a clean, airtight glass jar. A wide-mouth jar works best as it makes it easy to scoop out the powder each time you want to use it.
Seal the lid tightly and store in a cool, dry place away from moisture and direct sunlight. Keep it away from your shower or bath area, where steam and humidity can get into the jar and cause the mix to clump.
Stored correctly, your bath soak will keep for up to three months.
How To Use Homemade Bentonite Clay Bath Soak
Step 1: Draw Your Bath
Fill your bathtub with hot water, as warm as you find comfortable. The warmth helps the powder dissolve and disperse evenly through the water, and makes for a more immersive, relaxing soak overall.
While the tub is filling is the perfect time to set the atmosphere. Dim the lights, light a candle, put on some music. This is your time.
Step 2: Dissolve the Bath Soak
Rather than tipping the powder directly into the running water and risking clumps, dissolve your bath soak first for best results.
Scoop ¼ to ½ cup of the bath soak powder into a small non-metallic bowl or mug, then add a small splash of warm water and stir until smooth and lump-free.
Once dissolved, pour the liquid clay mixture into the bath while it’s still filling and swirl it through the water with your hand to distribute it evenly.
The water will turn cloudy and may take on a warm golden tinge from the calendula. This is completely normal and exactly what you want.
If you’re adding apple cider vinegar, pour it directly into the bathwater at this stage.
Step 3: Soak for 15–20 Minutes
Ease in and soak for at least 15 minutes, up to 20. Try to keep as much of your body submerged as possible to let your skin fully benefit from the mineral-rich water.
Breathe, relax, and let the warmth do its thing. If you added essential oils, you’ll notice the steam carries the scent beautifully. This is one of the loveliest parts of this recipe.
Step 4: Rinse Off and Moisturize
When you’re done soaking, rinse off with warm or cool water using a handheld shower head or by stepping into a quick shower. This removes any clay residue from your skin and leaves it feeling clean and smooth.
Gently pat your skin dry with a towel, then apply your favorite body moisturizer or body oil while your skin is still slightly damp. This locks in softness and leaves skin feeling velvety.
Drink a glass of water after your bath to rehydrate, especially if the water was very hot.
What Each Ingredient Contributes to this Bath Soak Recipe
Bentonite Clay
Bentonite is a naturally occurring mineral clay that has been used in beauty and skincare for centuries.
In a bath, it gives the water a wonderfully silky, mineral-rich feel and leaves skin feeling exceptionally clean and soft after rinsing. It disperses easily in water and is gentle enough for most skin types.
When buying bentonite clay for baths, look for food-grade or cosmetic-grade powder. Avoid anything labelled for construction or industrial use.
Magnesium Flakes
Magnesium flakes (magnesium chloride) are a staple in spa and bath products for good reason. They dissolve beautifully in warm water and give the bath a luxurious, softening quality.
Magnesium flakes are a classic ingredient in high-end bath soaks and are widely available from health food stores and online.
Can you substitute Epsom salts for magnesium flakes? Yes, Epsom salts (magnesium sulfate) are a very easy swap and work just as well in this recipe. They’re also typically cheaper and easier to find in regular supermarkets.
Baking Soda
A simple but hardworking ingredient. Baking soda softens bathwater, helps the other ingredients disperse evenly, and leaves skin feeling silky smooth after soaking. It also helps stabilize the pH of the bath mix, keeping it gentle on the skin.
Calendula Powder
Calendula (pot marigold) is one of the most beloved botanicals in natural skincare, known for its gentle, soothing properties and its affinity with dry and sensitive skin types.
In this bath soak recipe, calendula powder adds a beautiful warm golden colour to the water and leaves skin feeling noticeably soft. It also has a mild, pleasant floral scent.
If you have particularly sensitive skin, calendula is one of the best ingredients you can add to a bath recipe.
Ginger Powder (Optional)
If you enjoy the sensation of a warming bath, ginger powder is a wonderful addition. It creates a gentle, tingly warmth across the skin as you soak, particularly noticeable in the first few minutes. It also adds a spicy, invigorating scent that pairs beautifully with citrus essential oils.
A note on sensitivity: Ginger can be quite stimulating on the skin, particularly for those with sensitive skin or at high concentrations. Start with just 1–2 tablespoons on your first try rather than the full quarter cup, and skip it entirely if you have reactive or broken skin.
Apple Cider Vinegar (Optional)
A traditional beauty bath ingredient, apple cider vinegar adds a satisfying, gentle fizz when poured into the warm water. It has a long history of use in DIY bath and beauty routines and is thought to help leave skin feeling smooth and balanced.
Add ½ cup directly to the bath — don’t mix it into the dry powder blend.
Best Essential Oils for a Clay Bath Soak
Essential oils are entirely optional in this recipe, but they do transform the experience. The warm water and steam carry the scent beautifully, and you can easily switch up the essential oil blend to suit your mood or the season.
- For a Calming, Relaxing Soak: Lavender, Roman Chamomile, Bergamot
- For an Invigorating, Uplifting Soak: Grapefruit, Lemon, Cypress
- For a Warming Winter Soak: Juniper Berry, Cedarwood, Sweet Orange
- For a Woodland Spa Atmosphere: Frankincense, Sandalwood, Eucalyptus
Always dilute essential oils in a carrier oil, such as sweet almond, jojoba, or fractionated coconut oil, before adding them to bathwater. Never add undiluted essential oils directly to the bath as they don’t disperse in water and can irritate the skin.
Read this detailed guide about using essential oils in the bath.
When it comes to essential oils, quality matters, more so as the oils will be in direct contact with your skin throughout the soak. Always use 100% pure, high-quality essential oils.
Plant Therapy is my #1 recommended brand for their high quality, purity, and transparency.
Tips, Variations & Gifting Ideas
Adjust the recipe for your skin type. For very dry skin, increase the calendula and reduce the baking soda slightly. For oilier skin, the clay-forward base recipe works beautifully on its own.
Skip the ginger for sensitive skin. If you’re new to this recipe or have reactive skin, make the base recipe without ginger first. You can always add it later once you know how your skin responds.
Make a bigger batch. This recipe scales up easily. Make four or five times the quantity and store it in a large jar so you have enough for several weeks of baths.
Seasonal swap ideas. In summer, try a citrus-and-mint blend. In winter, switch to warming spices and wood oils. The base recipe stays the same, only the essential oils change.
Gifting Ideas
Decant the finished bath soak into a pretty glass jar, tie with a ribbon, and add a small label with the instructions. Include a card suggesting an essential oil blend. It’s a thoughtful, genuinely useful handmade gift for birthdays, Mother’s Day, or the holiday season.

Safety & Precautions
The tub can get slippery when clay is involved. Take care getting in and out, and consider a non-slip bath mat.
Use a drain strainer or plug cover to catch any clay residue and prevent build-up in your pipes.
Patch test first if you have sensitive or reactive skin, particularly if you’re including ginger powder.
If you are pregnant or have any existing skin conditions, check with your doctor or dermatologist before trying new bath products.
Keep the bath at a comfortable temperature. Very hot water for extended periods is not suitable for everyone — listen to your body.
Frequently Asked Questions
Can I use this bentonite clay bath soak every day?
This recipe is gentle enough for regular use, but 1–3 times a week is a good rhythm for most people. If you have dry skin, soaking in very hot water too frequently can strip the skin’s natural moisture. Always follow up with a good moisturizer.
What can I use instead of magnesium flakes?
Epsom salt (magnesium sulfate) is the easiest and most widely available substitute and works just as well in this recipe at the same quantity.
Is bentonite clay safe for sensitive skin?
Bentonite clay is generally well-tolerated and is widely used in cosmetic products. However, as with any new skincare ingredient, it’s worth doing a patch test first if you have sensitive or reactive skin. Dissolve a small amount in water and apply to the inside of your wrist for 10–15 minutes before your first full bath.
Can I use this bath soak recipe in a jetted or whirlpool tub?
It’s not recommended to use clay-based bath soaks in jetted tubs. The clay can accumulate in the jets and pipes over time. Stick to a regular soaking tub for this recipe.
Is it okay to use the bath soak if the mix has become clumpy?
Clumping usually means some moisture has gotten into the jar. If the mix smells fine and hasn’t changed color significantly, you can break up the clumps with a spoon, and it will still work in the bath. To prevent this from happening, store in a truly airtight jar well away from the bathroom’s steam and humidity.
Can children use this bath soak?
The base recipe (without ginger or essential oils) is gentle, but remember, children’s skin is more sensitive than adult skin. To make this recipe child-friendly, leave out the ginger powder entirely and only use skin-safe, child-appropriate oils at a very low dilution.
Why does my bathwater look cloudy?
This is normal. Bentonite clay disperses in water, making it appear murky or cloudy. The calendula powder also adds a warm golden tint. Both are signs that the ingredients are doing exactly what they should.
Can I add the essential oils to the whole batch when I make it?
You can, but it’s not ideal for long-term storage. The oils can cause the dry mix to clump over time, and the scent will fade faster. For best results, add your essential oils to each portion just before use.
