Our shower tablets are all natural and scented with essential oils. Indulge in an in-shower aromatherapy experience. To use, place one tablet on the shower floor or bathtub edge ideally away from the direct stream of water. As the tablet fizzes, the essential oils will be released into the shower. For best use and to help prolong the scent, place tablet in a small dish (so the water doesn't drain immediately after activating the tablet).
