Collection: Bath Bomb Molds

Shapes & Sizes for Every Bath Bomb

Plastic snap-together Bath Bomb moulds in classic rounds and hearts, plus durable alloy steel moulds for crisp, professional finishes in round, conch shell, and scallop shell designs. Sizes range from 55mm to 95mm, so you can make anything from petite gift bombs to bold statement pieces.

Pack your mixture firmly, let it air dry undisturbed, then ease the mould apart — most bath bombs are ready to package within 48–72 hours. Try the doughnut mould for a fun, eye-catching shape that's perfect for gifts and market stalls.
