The best bath salts for a relaxing soak depend on your personal preferences and needs. For a calming and stress-relieving soak, look for bath salts with lavender, chamomile, or eucalyptus essential oils. For muscle pain relief, choose bath salts with magnesium or epsom salt. Himalayan salt and dead sea salt are also popular choices for their mineral-rich properties. Some popular bath salt brands include Dr. Teal's, Herbivore Botanicals, and Lush Cosmetics.
