Tranquility is an earthy essential oil blend of chamomile, lavender, patchouli, and geranium. The Shower Equivalent of a Bath Bomb- Because You Shouldn't Have to Miss Out if You Don't Have a Tub! Our Shower Steamers are Made without Any Coloring, So You Don't Have to Worry About Cleaning Up After. You Can Place the Shower Steamer Where You Would Leave a Bar of Soap in the Shower- So it Gets Splashed On - But Not Soaked - for a Light Aromatherapy Experience or You Can Place Them Next to the Shower Drain for a Stronger Scent (We Recommend this Usage for Larger more Open Showers/Bathrooms)
