Common questions
Questions About the Cube Mold
What size bath bomb mold should I buy?
The 2" is our most popular size — it makes a bath bomb that's perfect for a single soak and fits nicely in packaging. If you're making party favors or gift bag fillers, go smaller (1" or 1.5"). If you want something that feels luxurious to gift or sell, try the 3" or 3.5". Oursize guideshows exactly what each size looks like.
Will this mold work with my bath bomb recipe?
Yes — this mold works with all standard bath bomb recipes including citric acid and baking soda bases. The smooth interior walls are designed for clean release regardless of your exact formula. If your mixture is wetter than usual, let the bath bombs set for a few extra minutes before removing.
How long does the mold last?
With normal care, these molds last for hundreds of batches. Every mold comes with a 2-year warranty — if it develops a defect in materials or workmanship under normal use, we'll replace it. Just contact us.
Can I use this mold to sell bath bombs?
Absolutely — many of our customers run Etsy stores, sell at markets, and supply local boutiques using these molds. The 3" and 3.5" sizes are especially popular for retail-ready bath bombs. If you need a custom shape or logo pressed into your bath bombs, check out ourcustom mold service.
How do I clean and store the mold?
Rinse with cold water after each use and dry thoroughly before storing. Avoid hot water. Do not soak or put it in the dishwasher. Store in a cool, dry place away from direct sunlight.
