Editorial Guidelines Updated on September 28, 2022 Share Tweet Pin Email After a long, busy day, there's nothing better than a hot bath—except, of course, a hot bath enriched with fragrant bath salts. It's surprisingly easy to make your own custom bath salt blends to suit your needs (like soothing sore muscles or softening skin), then scent them with your favorite essential oils. As a finishing touch, use food coloring to make your salt blend a pretty, soothing color. What You'll Need Materials Bath salt labels Container Coarse sea salt Epsom salts Baking soda Essential oils (Vitruvi "Retreat Blend" Essential Oils) Food coloring Instructions In a large bowl, mix to combine: 6 parts coarse sea salt; 3 parts Epsom salts, to soothe tired muscles and reduce inflammation; and 1 part baking soda, to soften waters and alleviate skin irritation. Add a few drops of essential oils and combine. Add a few drops of food coloring until you achieve the desired shade. If you intend to present the bath salts as gifts, be sure to store them in a stoppered and labeled container (using our printable labels) to keep out moisture.
