Best Bath Bomb Making Kits for Beginners: 4 Worth Trying
The best bath bomb making kits for beginners, from natural organic sets to family-friendly kits. Honest picks with what's included and what to expect.
My friend Anna has been making her own bath and body products for years. She started with homemade soap a few summers ago, then moved into scrubs and then bath bombs, and now her bathroom cabinet is basically a small spa supply closet. Last winter she brought over a box of bath bombs she had made to give away as Christmas gifts, and they were genuinely beautiful. Round, fizzy, packed with dried lavender and rose petals that floated out when they hit the water.
I had tried making bath bombs exactly once before, years ago, with one of those Pinterest setups where everything goes sideways and you end up scraping a crumbly mess out of the mold. The results were nothing like hers. She told me the problem is almost always the kit. Beginner kits that include everything pre-measured and with clear instructions make the process nearly foolproof. Kits that hand you raw materials and expect you to sort out the ratios yourself leave too much room for error.
This past spring she walked me through the process using a few starter kits she had tested over the years, and I ordered two more on my own to try with the boys one afternoon during our homeschool break. The four kits in this post cover a range of approaches, from simple and natural to larger all-in-one sets. They are all genuinely beginner-friendly based on Anna's expertise and my own first-timer experience.
What Makes a Good Beginner Bath Bomb Kit
The fizzing reaction that makes a bath bomb work is a simple one: citric acid and baking soda react when they hit water and release carbon dioxide bubbles. The ratio has to be right, the mixture has to stay dry until it goes in the tub, and the oils in the formula are what make the water feel soft and moisturizing. When the ratio is off or moisture gets in too early, the bombs either crack, crumble, or start fizzing in the mold before they get a chance to set.
A good kit handles most of that for you. Here is what actually matters when picking one.
Pre-measured or portioned ingredients. The most common beginner mistake is adding too much moisture before packing the molds. Kits that come with pre-measured dry ingredients take the guesswork out of the most critical step. If you are measuring your own ratios from scratch, one damp towel nearby can ruin a whole batch.
Molds included. Round two-piece molds are the standard. Some kits use cupcake liners instead, which produce a different shape and do not require the same precise packing technique. If you want round bath bombs, look for kits that include actual molds rather than expecting you to source them separately.
Essential oils versus fragrance oils. Natural kits use essential oils, which add fragrance without synthetic ingredients. Some kits include fragrance oils, which are often stronger-smelling but not always skin-safe at high concentrations. Anna prefers essential oils, and for anything the boys might be sharing the bath with, I agree with her.
Colorants. Safe colorants for bath bombs are either cosmetic-grade micas or skin-safe food coloring. Neither should stain the tub if used in the quantities a kit provides. Be cautious with any kit that does not specify the grade of its colorants.
What you actually make. Kits that produce something you want to use or give away are the ones that motivate you to make a second batch. A first batch that dissolves cleanly, smells good, and leaves the water silky will have you reaching for the next kit before the tub drains.

DIY Gift Kits Bath Bomb Making Kit
The DIY Gift Kits set is the one Anna points people toward first when they want something simple and well-sourced. Everything in it is made in the USA with 100% pure ingredients, no fillers or synthetic additives, which was the first thing she noticed when she looked it over. The dry ingredients come pre-measured and separated: baking soda, citric acid, cornstarch, and Epsom salts are all portioned correctly for the recipe so you do not have to weigh anything yourself.
The kit includes four pure essential oils (lavender, lemon, eucalyptus, and grapefruit), which gives you enough variety to make batches with different scent profiles. It also comes with gloves, a spray bottle for activating the mixture, cupcake mold liners for shaping the bombs into a rounded cupcake shape, and a reusable round mold. The instructions walk through each step in order, and Anna said the directions are more detailed than most kits she has tried at this price point.
The cupcake shape is different from the classic round ball, which is worth knowing if you have a specific look in mind. For gifting, the cupcake shape actually photographs well and stacks nicely in a basket or box. If you want a more traditional round bomb, the included round mold handles that with a slightly different packing technique.
The honest limitation: there is no colorant included. The bombs come out a natural cream color. For many people, including me, that is actually a feature rather than a drawback. But if you want the bright pastel colors you see in commercial bath bombs, you will need to add cosmetic-grade colorant separately.
DIY Gift Kits Bath Bomb Making Kit, Make 12 All Natural Bath Bombs at Home
Hand-packed in the USA with 100% pure pre-measured ingredients including baking soda, citric acid, cornstarch, and Epsom salts. Includes four essential oils, gloves, spray bottle, cupcake mold liners, and a reusable round mold. Makes 12 bath bombs with no synthetic additives. No colorants included, so the finished bombs are a natural cream color. Anna's first recommendation for anyone who wants simple, clean, and genuinely well-sourced.
Earthy Good DIY Bath Bomb Kit
If you want something that leans into the botanical and organic angle, this is the kit for that. The Earthy Good set uses 100% natural, organic ingredients and includes actual dried botanicals, dried rose, chamomile, and lavender, that you press into the surface of each bomb before it sets. The finished result looks like something from a boutique. Anna made a batch of these for her sister's birthday and they were the kind of thing you have to explain you actually made yourself.
The kit comes with the dry base ingredients, essential oils for fragrance, molds, an instruction guide, and a Japanese Furoshiki cloth for wrapping the finished bombs as gifts. The cloth is a thoughtful detail. Most beginner kits come with a plastic bag at best, and the wrapping cloth makes the gift feel more intentional without any extra shopping on your part.
It makes 10 mini bath bombs rather than full-size ones, which is worth knowing. Mini bombs are a practical size for daily use since you might not want a full-size bomb every single time, and they are more economical to give away because you get more individual pieces out of one batch.
The limitation here is that the visual results vary more than with synthetic colorants. The rustic, botanical look is part of the appeal for many people, and it certainly is for me. But if you want consistent bright color or a perfectly uniform finish, this kit is not designed for that result.
Earthy Good DIY Bath Bomb Kit With Organic Ingredients 100% Natural
All-natural and organic ingredients including essential oils, dried rose, chamomile, and lavender. Includes molds, instruction guide, and a Furoshiki gift-wrapping cloth. Makes 10 mini bath bombs with a beautiful botanical finish. No parabens, sulfates, or synthetic colors. The most gift-ready kit on this list, and the one whose results look most like something you would buy rather than something you made at home.
Dewiitine DIY Bath Bomb Making Kit
The Dewiitine kit is the most complete set here in terms of what comes in the box. At 33 pieces, you get the dry base ingredients, floral-scented fragrance oils, colorants, metal molds, mixing tools, and enough material to make a solid first batch. Everything you need, from measuring spoons to the molds themselves, is included so you are not guessing about whether your mixing cup is the right size or whether your mold is compatible with the recipe.
Anna's take on kits like this one is that the piece count can be misleading until you open it and see that many of those 33 pieces are small mixing cups, spoons, and tools rather than separate batches of ingredients. That said, having everything in one place means no scrambling mid-batch, which matters when you are working with a recipe that has to stay dry right up until it goes in the mold.
The floral scent the kit is designed around, a rose and lavender blend, is pleasant and not overwhelming, which matters when you are making something you will actually use in the bath. The boys and I made our first batch with these molds and had very few surprises.
The molds are metal two-piece rounds, which produce the classic sphere shape. Metal molds pack more firmly than silicone and release more cleanly, giving the surface of the finished bomb a smooth, precise shape. One thing to know: the colorants are included but produce lighter pastel results rather than vivid color, and the fragrance is pre-set to floral, so if you want to customize the scent you will need to swap in your own oils.
Dewiitine DIY Bath Bomb Making Kit, 33 Pcs with Molds, Soap Making Supplies
The most complete kit in terms of included tools and supplies. 33 pieces including metal sphere molds, floral fragrance oils, colorants, and all mixing tools. Metal molds produce smooth, cleanly shaped round bombs. Good pick if you want everything in one box without any supplemental shopping. The boys and I used this for our first batch and had very few surprises along the way.
Premium DIY Bath Bomb Making Kit
This kit does one specific thing differently from the others: the molds make large, jumbo-sized bath bombs. If you have ever dropped a commercial bath bomb in the tub and thought it seemed on the small side, these are the proportions you were imagining. The finished size is noticeably larger than what most beginner kits produce, which makes them especially satisfying as gifts.
The formula is safety tested and certified non-toxic, which matters if kids will be involved in the making or the using. My boys were interested in every step of the process, and for anything that goes in the bath with them, knowing the ingredients have been independently tested is reassuring. The instructions cover both the technique and the safety precautions clearly enough that you do not need to look anything up separately.
The kit includes color and scent options so you can make several batches that look and smell different, which is a practical detail for a larger kit. The variety keeps the project from getting repetitive if you want to make a full set of gifts rather than all the same thing.
The honest note: jumbo bath bombs take longer to pack and cure than standard-size ones, and they are more sensitive to moisture during the setting process. The instructions address this, but it is worth reading through before you start rather than discovering it partway through your first batch.
Premium DIY Bath Bomb Making Kit - Super Jumbo Bath Bombs Ingredients and Supplies Set
Makes larger, jumbo-sized bath bombs using safety tested and certified non-toxic ingredients. Includes color and scent options for variety, molds sized for the jumbo format, and clear instructions for both technique and safety. The right pick if you want results that feel impressive to give away or if you simply prefer a bath bomb that fills the tub. Read the instructions first, because jumbo bombs are less forgiving of rushed packing than standard-size ones.
Tips for a Successful First Batch
Most bath bomb failures come down to one of three things: too much moisture in the mixture, wrong ratios, or rushing the mold. A few simple habits make a real difference.
Keep everything dry until the very end. Water is the enemy until the bomb is in the tub. Do not use wet hands and avoid working near a steaming pot or running dishwasher. Even humidity in the air can start the reaction early, giving you a grainy, crumbly mix instead of a smooth one. Anna works with a dehumidifier running in the corner on humid summer days, which sounds like overkill until you have ruined a batch from air moisture alone.
Use witch hazel, not water, as your activator. The liquid activator most kits include is there to lightly bind the mixture so it holds its shape when packed. A fine mist of witch hazel is the standard recommendation because it introduces less moisture than water and activates the binder without setting off the fizzing reaction prematurely. Too much of any liquid and your batch will start fizzing in the bowl before it ever sees a mold.
Pack the molds firmly. Underpacked bombs often crack when they release from the mold or later when they finish drying. Fill each half with enough mixture to slightly overfill it, then press the two halves together firmly before setting aside to cure. If the surface is rough after releasing, that usually means the mixture was too dry when packed.
Wait the full cure time. Most bath bombs need at least 24 hours to firm up before they are handled or gifted. The ones with dried botanicals pressed into the surface need more time, not less. Unmolding too early leaves fingerprints and can cause the outer layer to crack along the seam.
