Baths are a great way to benefit from crystal energy.  Many people find that bathing with rose quartz, clear quartz points or other water safe crystals or even   plain old rocks enhances the bathing experience dramatically. The water also clears and vitalizes the crystals as well.
Bathing with the crystals is also a good way to commune and attune with stones because the water will enhance the vibration of the stones and help amplify your sensitivity and ability to connect and harmonize your energy and awareness.

I’ve bathed with crystals and rocks quite often. I discovered the benefits when we lost the stopper for the Tub at our old house and used a big ordinary old rock to hold a rubber flat stopper down and noticed that the baths became much more refreshing. After we got a plug and removed the rock I noticed a decrease in the vitalizing quality of the baths, we started bathing with rocks again because it did make a difference.

A related bath method for aura cleansing is to use sea salt in the tub. This may be harsh on soft crystals it is fine for people. A combination of Sea salt, Epsom salts and Bicarbonate of soda is also used for this sometimes. Usually it is suggested that ten minutes is long enough for a bath in this combination. A few drops of lavender or other essential oil or a few cups of strong herbal tea can also be added to your tub.

You can use flower essences, herbs or essential oils in the bath with your crystals and stones.

You can put stones and crystals in your bath directly, or use infused gem water, gem elixirs or Gem essences. These are usually made by placing stones in or around water and infusing or charging the water with the gem energy.

Gem waters are usually those where the crystal or stone is simply kept in the water for a while before the water is used. Gem Elixirs and essences are made by charging the water with the stones in sunlight, moonlight or with crystal Shakti energy or by intention or in ritual.

Elixirs can be used without being diluted /expanded before use. Gem essences are made from the elixirs and are extended and can be preserved in the same way as flower essences with the addition of a little Brandy, glycerine or vinegar.  A few drops of a commercial or home-made gem essence are enough to carry the gem vibration through the water.

You can also add elixirs or essences to a spray bottle of water and spray this on the walls of the shower stall and shower head. These sprays are also used for aura and room cleansing.

You can run crystal energy as a Shakti into the tub either directly if you have that ability or have been attuned to one of the systems that works with crystal Shakti

Some people find it effective to hold a stone in their receptive hand (usually the left in right handed people) and place their projective hand in the water with the intention that the energy be transmitted to and held in the water.

Rose Quartz, Clear Quartz crystals, Rainbow Quartz and Granite are among the most favoured stones for bathing with. Most of the members of the quartz family make good bath companions these include Amethyst, Aventurine , Carnelian, Garnet, Rose Quartz, Citrine, Chyrosphase, Bloodstone, Jasper, Agate, Onyx, Tigers Eye.

You will probably want to put small stones in a cloth bag or a colander or some other container which is also bath safe so that the crystals cannot go down the drain or get chipped.  A seashell such as abalone can be used as a container. It is best to avoid putting glass in the tub because of the possibility of breakage.  Some people make a slit in a sponge so that they can slide a crystal into the centre to protect it. It is possible to buy small bowls carved from marble, jade, carnelian or adventure etc. one of these could be used though the cost of these bowls may be prohibitive for bath use.

Some stones can chip or crack in hot water you probably won’t want to put the most precious and perfect stones in the bath. There are quite a few stones that could be dissolved or damaged in water Halite (salt), Sylvite, Desert Rose Selenite, all Selenite, Gypsum, Angelite, Azurite, and Talc. Calcite, Alabaster, Sulfur dissolves in salt water. I have been told that any stone that has a name ending in ite can possibly be damaged by water though I am not sure about that. There are stones that rust like iron ore or can be toxic such as stones with copper, lead and arsenic these should never be used in your bath.

Another way to get crystal energy into your bath is to put a charged stone in with your bath salts or bubble bath and use intention to charge the salts with the energy.  You may like the energy from keeping a small crystal point in the bottle of shampoo or liquid soap or shower gel. There was once a shampoo (Prell) which   was sold with a cultured pearl in the bottle in the 50s. You may also enjoy experimenting with putting colour in your bath water for healing purposes.
