These bath bombs have a secret inner pocket of rose petals

Natural bath bombs are relatively easy to make since they require only a few main ingredients and very little in the way of equipment. Making a small batch should take you well under half an hour so it’s also a great project for those with little time. I’ve made these on my own as a rainy day project but I can imagine it would be really fun to make them together with friends or the younger ladies in your family.

The essential oils used in this recipe are gorgeously floral and work well with the dried lavender and rose petals I’ve chosen for decoration. Not only are there flower petals on top but there’s a secret cache of flowers that are released when the bomb is placed in your bath! Another thing that makes this recipe different is that I’ve included quick oats in the base recipe. Oatmeal turns your bath water milky and silky and is wonderful for soothing dry and irritated skin.

1. Sift the Citric Acid and Baking Soda (Bicarbonate) into a bowl. Sifting removes any clumps from either and will ensure a smooth and even consistency in your finished bath bombs. If you’re using a scale to measure your ingredients, place the bowl with your fine mesh sifter nested inside directly on top and pour the ingredients in. We like saving time!

2. Pour your quick oats into the bowl and stir really well. Next, drizzle your essential oils on top and mix everything really well. I find that using my hand is far better than a spoon since I can break any clumps with my fingers and make sure that the fragrance is evenly dispersed.

3. Now here comes the trickiest part to describe. You’ll want to spray this mixture with Witch Hazel until it reaches a slightly damp consistency. The best way to describe this is maybe damp sand on the beach that is just starting to dry out. With my mini spritzer I spray three squirts and then mix really well with my hand. I keep adding three more squirts and mixing until the consistency feels right. What you’re looking for is the mixture holding form when you squish it into a ball in your hand. With my mini sprayer this took eighteen squirts though of course your sprayer may be different.

4. Bath bomb moulds come in two pieces with one side fitting inside the other. Take the half that has the lip that fits inside the other half and place a few dried flower petals at the bottom. These will be the pretty decoration you see on the top of the bath bomb so arrange the flowers in an attractive manner.

5. Take a handful of the damp bath bomb mixture and carefully pour it on top of your flower arrangement. Use both of your thumbs to compact the mixture down but leave a hollow in the centre. Fill this hollow with more dried flower petals and then sprinkle more bath bomb mixture on top. Don’t compress the top mixture just yet and set this half of the mould down for a moment.

6. Take the second half of the mould in your hand and fill it with bath bomb mix. Press down with your thumbs to compress but don’t leave a hollow this time. Top it off with a bit more bath bomb mix and like the other half, don’t compress this top layer yet.

7. Carefully pick up both halves of the moulds and place them together. Press firmly so that the mixture from both halves compresses together.

8. Pull the ‘bottom’ mould off your bath bomb then gently tap the bomb out of the second half and onto a surface where it can dry. If your surface is too hard, it’s likely that the bottom of your bath bomb will flatten so I dry my own bombs on a folded towel with a sheet of cling film on top.

Depending on size, Bath Bombs can take anywhere from twelve to twenty-four hours to dry. After this, you’re able to package them up, set them somewhere to scent the room, and eventually pop them into your bath for fizzy and fragrant relaxation.

  1. I have seen a lot of DIY recipes, but this is one of the best! Your explanation and step by step tutorial is awesome and simple!
    Thank you so much. I can't wait to make some for myself.

  2. Oh, I love these! Very similar to ones I make and sell at the Farmer's Market. They can be so delicate I always have to make and package them so carefully! These turned out so pretty. Pinning this as we speak.

    Thanks for sharing! What can I substitute for the lavender? Thanks!

    • It's really up to you! For the flowers you could use blue cornflowers and for the essential oil there are plenty of options that you can blend Geranium oil with – Sandalwood and Ylang Ylang spring to mind.

  5. Kat says:

    Quick question – won't the oats & flowers leave a mess in the tub once you're done bathing? I'd love to make those but am concerned about my pleasant relaxing bath being marred by having to clean up a messy tub afterwards?

  6. Stick with making basic bath bombs then Kat 🙂

    Where is a good place to order Rose Geranium Essential Oil?

    Where, specifically, did you get that exact mold?

  9. IJGL says:

    Gorgeous! Does it have to be witch hazel, or could it be any kind of liquid, like rose water?

    I would love to do this, but unfortunately I don't buy things online. If you can name anywhere to buy in Markham, Ontario, Canada, I would very much appreciate it. Thank you.

    a quick question – what am I doing wrong because the two halves don't want to compress together. how long do you leave the ball before trying to take it apart…my keeps on coming loose from one another.

    • It sounds as if the mix is too wet and compacted. When you try again, fill the centre with flowers then add a loose covering of bath bomb mix on top. The mix should also be loose (rather than squished down) at the top of the other half of the mould. When you press the two pieces together, the loose mix from both sides should hold together more easily.

      • Hi there. I just made the bath bombs (sooo awesome thank you so much for this! Best I’ve researched!)
        I am making Christmas gifts, so I doubled the recipe. First mold squishing went quite well. I had to spray a bit more for the second mold as it seemed to be drying out (it’s a mold with 5 round in a circle), half of them stuck together. As I’m filling, I notice the mixture is drying (am I doing this too slow?) So I had to spray more witch hazel. I think it got too wet – mixture wasn’t white anymore – more of a grey. By the third mold squishing, they would not hold together. I tried letting it dry out a bit, trying again, no go. Still grey too. I let it dry out a bit more and I also put it all through the sifter again. I can’t get the mixture to hold together anymore.

        Did I ruin it? If I let it dry out overnight, do you think I’d be able to try again? I used roses, lavender, and chamomile (dry mix/blender to a fine powder with colloidal oatmeal) and roses/lavender in the bottom of the mold cups.

          Hi Jennifer! What you’re running into is one of the biggest problems with making large batches of bath bombs. The dry ingredients start bonding with the wet and dry out. You can still squish it into moulds and it will be okay but if you’re using two-piece moulds they probably won’t stick together. More witch hazel doesn’t help but hopefully your batch dried in the moulds OK. Next time, make one batch then make a second afterwards 🙂

    wow this is amazing please make some more bath bombs I need the recipe for more maybe try violet? xxxx

  14. Nonsensenargles says:

    All but one of my bath bombs melted into a squishy lump. Is this because the mixture was too wet? Or not compressed enough? Or is there something else that could’ve caused this?

    • lovelygreens says:

      Too much witch hazel probably!

    • Bobbi says:

      Yeah it’s the witch hazel try using water next time and it should all work out just fine

      • lovelygreens says:

        It doesn’t have anything to do with using water or witch hazel actually – it’s how much liquid you use. Just try with A LOT less. I’m talking just a few squirts, mixing it in, then repeating. The consistency of the mix should not be wet. It should just be moist enough to hold its form when you squeeze it together in your hand.

    I just tried these I was fine until the end maybe you can see what I am doing wrong. So I sprayed the mixture until it was a damp sand texture just enough so it holds a form then I put them in the molds all went well there. When I went to open the molds I notice the middle didn’t stick together so I had to pull them out and just try to freehand making them into a ball. Well I let them sit out to dry and now it looks like a cookie that is just starting to get its shape in the oven. Not sure what I did wrong :/

    • lovelygreens says:

      They were probably too damp Kim – it’s happened to me many times! What I’d recommend is squishing the bath bomb material into a silicone cupcake (or specialty shaped – hearts?) mould next time. That way you don’t have to worry about the two pieces sticking together properly.

  17. Mia says:

    Would the chunks of fruit and oatmeal be in chunks at the bottom of the bathtub??

  18. Dee Ashby says:

    i have been trying to make bath bombs with rose petals, the petals are dry & have even tried freeze dried petals but after 24 hours or so they start going brown? Any tips for this, cheers

    • lovelygreens says:

      It’s possible that they’re getting too wet Dee but it’s hard to say. They shouldn’t turn brown that quickly – the bath bombs that I retail will often be stored for weeks.

  19. Cami T. says:

    How long are you supposed to leave the bomb in the mold? I tried it as the above tutorial is worded but they all fell apart. I thought it was the citric acid I bought. But now I’m reading some things that say to leave them in several hours or overnight. It smelled wonderful though. Thanks!

    • lovelygreens says:

      I literally have them in my moulds for about 30 seconds. If you leave them overnight there’s a chance they’ll stick in the mould and be impossible to get out. If you’re using silicone moulds it’s okay though since they flex and you can push them out.

      It sounds like your problem is that you’ve either not added enough witch hazel or you’re not working quickly enough. If you let the mixture set for too long the ingredients begin bonding together, making them less ‘sticky’ when you put them in the mould.

  20. Would it be possible for me to schedule this recipe on the Facebook and Twitter account I manage for East Devon district Council Countryside service? Perfect for Valentine’s Day? – Great blog!

  21. Hanna says:

    Hi! This might sound silly but will the oats and petals clog up the pipes? Would love to make this! Thank you!

  22. Thanks for sharing. Looks great but hate the word ” B O M B ” especially because baths are so relaxing.
