Bath Salt Guide

Why take a sea salt bath when a regular bath is plenty relaxing?


Most of us have seen bath salts. Lots of bath salts. In all sorts of scents, colors, sizes, and shapes. We’ll help guide you through the world of bath salts, and explain the many benefits and differences between the wide selection of bath salts available.


What is the real difference between all the options out there?


Bath salts can be sea salt or they can be mineral salts, like Epsom salt (magnesium sulphate) or pink Himalayan salt. Sea salt is the left over deposits from evaporated sea water, typically 5 gallons of sea water will yield a little over 1 pound of sea salt. Sea salt is respected for its healthy minerals and therapeutic properties.


Your largest organ, your skin, absorbs oil, water and nutrients and expels toxins and minerals through sweat. Your skin is like a big filter allowing stuff to enter, and forcing stuff to exit the body through its pores. When bathing in water with dissolved bath salts they can help cleanse and detoxify the body .

When these products are added to a bath it can ease muscle cramps, stimulate circulation and help relieve aches and pains in the joints and soothe achy, overworked legs and feet. 

Bath salts come in a variety of colors, sizes, grades and chemical makeups.

We have provided a list of bath salts that can be used on its own or with a combination of other salts, herbs, oils, colors and teas to create your own blend.


Ancient Sea Bath Salt

Also known as: Himalayan Bath Salt, Jurassic Sea Salt



Around 50 million years ago, during the formation of the great mountain ranges of today, ancient sea salt deposits were preserved and protected from pollutants by layers of sediment volcanic eruptions. These days, careful, sustainable harvesting unearths some of the finest, most beneficial bath salts available anywhere in the world.

HIMALAYAN BATH SALTS are full of up to 84 valuable trace minerals, giving them a beautiful, natural pink coloring that makes it a perfect option for attractive, clear packaging.


Atlantic Sea Bath Salt




Atlantic sea salts are collected from deep, clean ocean waters by channeling the sea water into large clay trays and allowing the sun and wind to evaporate it naturally. This white bath salt is great for adding coloring or scent, because it is naturally absorbent and generally comes in a variety of grain sizes.



Coarse Bath Salt



Coarse sea salt is large-grain bath salt about 2–3 millimeters in size. It’s ideal for sprinkling in the tub to dissolve for a bath. Coarse sea salts are a great addition to therapeutic bath salt blends with scented oils or colors, as their size helps absorb the oils and colorants easily.

Some sea salts are also available in jumbo sizes, ranging from the size of a dime up to the size of a golf ball. These sizes are beautiful, and ideal for making bath salt teas or salt potpourri (See Crystal Sea Salt below).


Crystal Sea Salt



Large crystal sea salt chunks are ideal for bath salt teas. Simply pour the salt crystals into an organza (or similar) bag, hang below the water spout, and let the water run over the sea salt rocks on its way into the bathtub. You can also add fresh or dried herbs to this mixture for aromatherapy and additional soothing benefits. Crystal sea salts can be used again and again.

You can also scent these large SEA SALT CRYSTALS and use them for décor or salt potpourri.


Dead Sea Bath Salt

The world’s first day spa was set up by Cleopatra on the shores of the Dead Sea. The “woman who time could not wither” and countless others have testified to the benefits of this special sea salt. DEAD SEA SALT differs greatly from other sea salts in mineral content, being made up of only 8% sodium chloride with a high percentage of magnesium, sulfates, and potassium.

You can bring that ancient, therapeutic experience home with our guaranteed authentic Dead Sea bath salts. Dead Sea bath salts aid in the treatment of common dry skin conditions like eczema and psoriasis. They’re known to reduce pain and inflammation from arthritis and rheumatism. The high mineral content is credited with the cleansing and detoxification of the skin. There’s even a bit of calcium—your body will love it!


Epsom Salt

Also known as: Magnesium Sulfate

News flash! Epsom salt isn’t actually salt. It should be called Epsom “salt.” Or Epsom salt-like. Epsom salt is a pure mineral compound of magnesium sulfate in crystal form, so it looks an awful lot like salt. But it has no sodium chloride, which is what salt is. We like to have all of the facts on the table here at SaltWorks.

Even though it isn’t salt, we don’t deny the many time-proven benefits of EPSOM SALT. A lot of people are magnesium deficient, which can be to blame for a number of maladies including heart disease, stroke, osteoporosis, arthritis and joint pain, digestive problems, and chronic fatigue.

A number of factors work against magnesium sulfate if you ingest it. We do not recommend ingesting Epsom salt (unless under the direction of a doctor). So, the very best way to benefit from this mineral is in the form of a bath salt. A dose of Epsom in your bath salts will power it up, and make it extra therapeutic.


European Spa Bath Salt

Also known as: Mediterranean Sea bath salt



Harvested using a similar process to Atlantic sea salt, European spa bath salt is another perfect salt for adding straight to the tub or as a raw ingredient in your bath product. Ideal for blending with essential oils for scrubs and body treatments, it is available in two grains, fine and coarse.

Fine grain is similar in size to table salt. Fine is great for exfoliating scrubs and body treatments, as well as in bath salt blends with herbs and powders.

Coarse is medium grain, closer to grinder salt. Coarse grain absorbs essential oils easily, and is great for therapeutic bath soaks and blends.


Fine Bath Salt




Fine bath salt can range from extra small grain, similar to baking flour, to a grain size closer to table salt. Fine sea salt blends well with herbs and powders in bath salt blends. These sizes are also recommended for facial and body scrubs, as they are less abrasive and gentler on sensitive skin.



Grey Bath Salt

Also known as: Sel Gris, Brittany Salt



Grey bath salt is traditionally hand-harvested in Guérande, France, in the Brittany region. The grey color is indicative of the salt’s natural trace minerals absorbed from its sea origins. Unwashed, unrefined, and additive-free, FRENCH GREY BATH SALT maintains all of its health-enhancing nutrients vital to the human body like calcium, potassium, copper, zinc, iron, and others. This salt is low in sodium, and certified organic by Nature et Progrès (France’s organic certifying body).


Organic Bath Salt

Organic salt cannot be “organically grown” because it is a mineral, not a plant, therefore in the United States we have no recognized organic certification for salt. However, there are countries that do issue their own organic certification for salt within their own borders. If you are looking for “certified organic” bath salt, then you are looking for salt with the Nature et Progrés (France) certification. This certification is awarded to saltworks that are located in a nature reserve, without risk of pollution, producing strictly by hand, without purifying the salt, and fulfilling the high standards of chemical analytics. Organic sea salt retains all its original vital elements, as it is not processed or refined.

Our Breton Grey Bath Salt has been certified as an Organic salt by Nature et Progrés in France.


Solar Salt



Solar salt is a term used to refer to salt that has been naturally dried by the sun’s heat. Generally, this refers to a white chunky sea salt, commonly sourced from the Mediterranean Sea, the North Sea, and the Atlantic and Pacific Oceans, among others. These large, bright crystals are very attractive when blended with smaller grained bath salts, such as Epsom salt or European spa bath salt. Many of SaltWorks’ wide selection of bath salts are considered to be solar salt.


Dendritic Salt

Dendritic is a highly purified sodium chloride that is crystallized under special conditions. In other words, dendritic salt is commercially manufactured and created by machines, rather than being a natural, carefully harvested product of the earth like the sea salts we specialize in.

Fans of dendritic salt like its absorptive capacity. A relatively small amount can be a great addition to bath salt blends. It helps maintain fragrance, holds essential oils stronger and for longer, requires less pigment, and reduces clumping. It’s a preservative for sea salt bath blends. It doesn’t have any therapeutic benefits that we know of.
