Soaking in a tub of warm water with bath salts can be a relaxing end to a day. Bath salts are sold commercially, but your choice in scents may be limited. You can easily create your own bath salts at home -- scented to your liking and much cheaper to boot. It doesn't take much time and you can make as much or as little as you want at a time. Bath salts also make nice homemade gifts.
Spread newspaper over your kitchen table. This protects the surface and provides easier cleanup in case you spill the salts or essential oil.
Place a mixing bowl on the newspaper. Use a measuring cup to measure 1 to 2 cups of sea salt into the mixing bowl.
Sprinkle 5 drops of your favorite essential oil, such as lavender, vanilla or lemongrass, into the salts. Put on a pair of rubber gloves.
Blend the salts with the oil, using your gloved hands. Use a large spoon to transfer the salts from the mixing bowl to a clean, glass jar.
Place the lid on the glass jar and let it set overnight. Open it in the morning to do a sniff test. If it is not as strongly scented as you prefer, add another drop of essential oil and stir it in with a teaspoon.
