Yahav was very good to work with. The custom mold I got worked really well and made such cute bath bombs!
I’m new to bath bomb making, but I wanted to get a nice mold that would be easy to use. I’ve used it a few times already, and I think it works great. Every bath bomb turned out perfect.
Absolutely in love! Ordered a custom mould, and it works amazingly and looks 櫨. Thank you so, so much 巳
Its always a pleasure working with Eli and her team , Thankyou for delivering such an amazing product that lines so well with my brand ???
It arrived so fast!! I can?? wait to use it to help my bath bomb making grow!! It is high quality too!!!
This is the second mold I have bought from The Bath Time and all I can saw is wow. Their products are awesome and their costumer service is unmatched. I highly recommend!
I have a bath bomb press and finally got a recipe that I can actually make bombs. I was nervous that it being steel was part of my bath bombs working out. However, I tested it with these molds and they turned out just as great! So glad I can have fun molds without having to pay an arm and leg on my press molds!

Prep
Mix your bath bomb batter until it holds its shape when squeezed.
Fill
Pack the mold firmly, slightly overfilling so every detail forms.
Press
Press down evenly to lock in the shape and sharp details.
Release & dry
Unmold gently and let dry for 24 hours before handling or packaging.
Pro tip: Batter too dry cracks, too wet spreads. Aim for damp sand that holds when squeezed.
