If you are new to soap making then you may wish to play it safe and stick to a simple bar shaped soap at first. They will come out of the mould with ease and are useful as everyday soap to use around the house, for hand washing and in the shower. Additions can also be incorporated into bar soaps, such as scents, petals and exfoliating seeds as you grow in confidence.
Those wishing to make soaps for specific occasions, such as good luck gifts, tokens to welcome overnight guests or as party favours, should opt for a novelty soap mould. These may incorporate text, embossed images, or allow the entire soap to emerge as a quirky shape. These soaps are often smaller than traditional bars, so consider the dimensions if you are intending to use your whimsical creations every day.
If you're interested in the science behind soap making, then why not try a home brewing kit?
Carefully check the number of individual soaps which can be produced before you commit to buying a soap mould, as the 'number of moulds' may refer to moulds with multiple cavities, or individual-cavity moulds. Those wishing to make numerous soaps can find packs of multiple cavity moulds, which make producing at scale a breeze. These are convenient for storage too, as individual cavity moulds can be stacked together when not in use.
Remember that the greater the number of cavities present on a soap mould, the smaller each is likely to be. When making your choice, take a moment to think whether you want a robust soap to hold in your palm for everyday use, or are happy to produce smaller bars that may be less practical?
Here are ten of the best soap dishes, to keep your creations in!
Silicone is a highly flexible form of plastic, which can withstand extremes of temperature and is naturally non-stick. It's the ideal material for soap moulds, as the melted soap is extremely hot when first poured. Once set, the silicone can then be easily peeled off without damaging the solid soap. A silicone mould is reusable and can be handy for baking too, as long as you aren't producing heavily-scented soaps.
Note that silicone soap moulds need to be robust to hold the setting soap securely, or distortion will occur. For extra support, you can purchase silicone moulds which sit inside a wooden or bamboo box. Just make sure that 'push holes' are present within the base of the box to allow for easy separation of the silicone mould and the outer casing.

With almost 2,000 five star ratings on Amazon, this set of four moulds (which make 24 bars of soap) has proven its quality and ease of use. The soap bars produced are of a good size, deep enough to last being used by a busy family, and are comfortable to hold.
The silicone tray is flexible for easy soap removal, yet firm enough for precision soap-setting. If you are a keen soap maker, then being able to make 24 professional-looking, uniform soaps in one go will really appeal!
Surrounded by a pine-wood casing for maximum stability, this silicone mould can then be easily removed once the soap has set thanks to the inclusion of push-holes in the base of the box. The cutting tools (straight or wavy) can then be used to slice up the soap into individual bars.
You can use the acrylic plastic inserts if you want to make swirly soap bars. Plus, they keep the different coloured soaps separate until almost set, at which point you can remove the dividers and swirl to create beautiful patterns!
This great-value selection includes both plain and patterned soap moulds. The set includes 13 moulds in total, including 1 large six-holed mould, plus twelve individual decorative moulds. Just be aware that the smaller soaps are rather petite, so make sure to check the measurements before buying.
With moulds for bars reading 'thank you' and '100% hand made' as well as four leaf clover and floral designs, there really is a soap for every occasion. This makes it the perfect choice for those wishing to make soap bars to give as gifts.
This pack of 15 food-grade silicone moulds will ensure everyone knows the soaps you produce are handmade! Thanks to the very professional-looking embossed message, the individual moulds can be used to create soaps for craft fairs, small businesses and much more.
The soap bars produced sit comfortably in your hand, but are towards the smaller end of the scale. So, once again, be sure to check the measurements before you buy.
These two moulds make a total of 12 adorably ditsy soap clouds. The soaps produced are a decent size as the moulds are deep, and filling them to the brim will create suitably robust bars for busy family life. For more delicate soaps, simply fill the moulds to your desired level.
This mould can be used to create a set of soaps with a classic sun and moon design. A great choice for when you have visitors, welcome overnight guests by placing a handmade soap on a folded towel atop a beautifully made bed.
The mould produces four palm-sized soaps, with flat bases which will stay put when placed on the side of the sink or bath. We recommend adding lavender or other relaxation-inducing essential oils when making soaps with this mould, for a truly dreamy combination.
Each of these hexagonal honeycomb moulds are adorned with a honey bee, and are thus perfect for those looking to make honey-scented soaps. Better yet, the six bars produced, are the perfect size and shape to hold comfortably in your palm.
The silicone apiary-inspired mould is solid enough to hold the soap in shape until it sets, yet flexible enough to ensures that the detailed bars are easy to remove. We think these moulds would make truly bee-utiful soaps if you love honey and bees.
This silicone mould is sturdy in construction, capable of holding the soap evenly in place until it sets. Rest assured that the four different delicate floral patterned soaps will emerge well-defined, thanks to the highly flexible nature of the mould.
The soaps produced are a useful size for daily hand washing, sitting comfortably in your hand, although you might decide they are just too beautiful to use. If you do keep the finished soaps out on display, be aware that the intricate designs will harbour dust. So just use them up and then make some more!
Ideal for animal lovers, these soap moulds could be used to make soap for the owner or for the pet. After all, artisan dog soaps are getting ever more popular! We think these soaps could even pass as cat prints, or those of a tiger or wolf, so they aren't just for dog fans either.
The soaps produced are fairly small, which in fairness keeps them looking realistically paw-sized. However, they are not as deep and robust as bar soap. That said, we think that their cuteness makes them ideal as a novelty gift or party favour.
These miniature alphabet soaps, with each letter measuring approximately 3 x 4 cm, are ideal if you want to make personalised gifts. You can simply fill the letters you need, and then pop out once hardened off.
These soap letters would be ideal for a fun bath or shower time with kids. Just be careful when it comes time to remove them as some of the letters are trickier to push out than others - especially if you fill the whole tray!
You can either use a pre-mixed melt and pour kit, which avoids the dangerous chemical reactions involved in traditional soap making, or you can use sodium hydroxide and water to make ‘lye’ (which is very corrosive), plus solid oils, liquid oils and optional essential oils.
Traditional soap making can be dangerous as it uses sodium hydroxide to make lye. We advise that you read all instructions carefully, follow a reputable recipe, wear protective goggles and appropriate gloves, and ensure that the soap is left to cure (neutralizing the strong alkali) before using the finished soap.
Yes, you can! Chop up small pieces of old soap. Heat 2 cups of soap scraps, plus 1 tbsp of tap water using a double boiler pan, until melted. Pour into 2 or 3 moulds and leave to set for 1 week. Remove from moulds and allow to harden for 3 weeks.
