If you prefer a shower to a bath, shower steamers (or shower bombs) are a great option. They're made with baking soda and citric acid, just like bath bombs. But rather than placing them into a tub, the steamer is placed on the floor of the shower. The water activates the fizzing reaction and releases the essential oils into the air. Each steamer should last approx 2-3 showers dependent on how long your shower is and how much water you splash on it.
