Saltwater Hot Tubs: The Basics – SpaCap

Saltwater hot tubs are becoming increasingly popular among spa owners. Like the ocean, saltwater spas are designed to regulate chlorine production without the need for chemical additives. If you’ve considered switching to saltwater, continue reading for a breakdown of the pros and cons.

The Saltwater Craze

The benefits of saltwater spas have been touted by many. The top reason hot tub owners make the transition is less dependence on chemical additives, but the following have also been reported:

  • Reduced odor. Because saltwater spas do not require chlorine tablets or bromine, there is less of a “chemical” odor associated with the water and spa itself.
  • Better water quality. Dry skin, irritation, and rashes are a few of the complaints shared by traditional spa owners, largely due to the use of chemicals. In contrast, saltwater spas help condition the skin and increase suppleness.
  • pH stability. In a traditional spa, careful attention must be paid to ensure pH remains at an optimal level. Unlike chlorine-dependent spas, saltwater hot tubs resist changes in pH.

Before Making the Switch

With so many benefits offered, saltwater spas are becoming more desirable among homeowners. Prior to making the switch, however, review these notes about saltwater spas:

  • Salt cells need to be replaced. Owning a saltwater hot tub comes with multiple responsibilities, including the need to replace salt cells every few years.
  • Corrosion is a concern. Some materials are not meant to be exposed to salt; thus, corrosion can be a problem if your saltwater spa is not well maintained.
  • Avoid low temperatures. Though not generally a problem for hot tubs, low temperatures can disrupt the salt cell and shut the system down. For spa owners in temperate climates, keeping the water above 60 degrees in the winter is essential.

Saltwater hot tubs provide owners with a healthy, relaxing way to enjoy the outdoors without traveling to the coast.

It really doesn’t matter what method you use to keep your hot tub water clean, you still have to have a cover to keep it warm. At, all we do is build the best hot tub covers in the world. When we started building covers, the standard in the industry was the traditional rigid foam filled cover. So that’s what we made.

What we found out very quickly was that no matter how you wrapped it, foam spa covers ALWAYS get saturated, heavy and or broken because the foam soaks up moisture.

So we set about building something better. It has gone through some improvements over the years but the lightweight hot tub covers we built lasted longer and insulated better than any foam filled cover ever could.
