Salt, or Sodium Chloride, is one of the most common elements on our planet, and people have been enjoying the benefits of sea-salt and mineral salt baths for hundreds of years. Certain concentrations of mineral salts has been used therapeutically to help detoxify and strengthen a person’s immune system.

Technological advancements have allowed for these salt water systems to be an option in today’s spas and hot tubs as well.

With tremendous improvements to Salt Water Systems, Marin County residents have chosen this eco-friendly, low maintenance alternative to traditional chemical treated pools and spas.
