When it comes to bath bombs, the bigger the better, so Bathorium decided to make the biggest (and succeeded). To say that the Aphrodite Bath Bomb is sizeable is an understatement at best. This flower-adorned bath accessory is gigantic, measuring 4.5 inches. It also emits a highly indulgent scent of vanilla, cocoa absolute, and Bulgarian rose, making for one sweet (but not overwhelming) soak. Needless to say, it’s one of the best spa gifts you’ll find in the bath category.
