The Top 11 Salt Water Hot Tub Benefits

To keep water clean, Caldera Spas salt water hot tub systems generate chlorine automatically from trace amounts of salt dissolved in the water. This method is far more efficient than adding chlorine by hand every week. But the advantages don’t stop there. Here’s a look at the top 11 benefits of salt water hot tubs, from experience to ownership, and why new innovations mean systems are more user-friendly than ever before.

Salt water hot tubs are gaining popularity as people look for more natural ways to improve their health and wellness. Compared to the chemicals found in traditional chlorine systems, salt water hot tubs offer a gentler, more relaxing spa experience. Not only that, but they’re also easier to maintain.

The Many Benefits of Salt Water Hot Tubs

1. Improved wellness

Salt water is denser than water without salt, which makes it easier for people to float. Increased buoyancy reduces the weight of gravity on joints and muscles, soothing tension as it lifts the body and the spirit. Just 20 minutes of hot tub use every day can turn muscle tension to comfort, soothe a busy mind, and improve overall well-being.

2. Fewer chemicals

Salt water systems constantly monitor chlorine levels in the water, so they only generate as much chlorine as is needed. That means fewer chemicals end up in the spa water which helps the water last longer. Plus, the water feels softer, smoother, and purer than water sanitized using a traditional system.

3. No odors

Salt water purification systems eliminate the “chlorine smell” that lingers around some pools and hot tubs. The smell is caused by chemical residues in the water due to inconsistent manual dosing of chlorine. Salt water hot tubs maintain a consistent level of chlorine which eliminates the residues. No chemical residues, no odors!

4. Less irritation

Fewer chemicals also means that salt water spas are less likely to irritate your skin and eyes. With a gentler overall experience, you can fully relax and enjoy all the wellness benefits without any annoying discomfort.

5. Fewer drains

Some salt water hot tubs — such as the new FreshWater®Salt System* — have to be drained only once a year with normal use, compared to three or four times a year for hot tubs relying on traditional chlorine. This saves hours of work every year, so you can spend less time maintaining your hot tub and more time enjoying it.

6. Conserves water

Because salt water hot tubs require less frequent drains and refills than traditional hot tub systems, salt water tubs use far less water. This means hot tub owners can enjoy the wellness benefits while knowing they’re conserving a limited resource at the same time.

Salt water hot tubs are more user-friendly

Salt water systems for hot tubs have been around for several years and have done an admirable job of providing users with clean water that contains fewer chemicals. But new innovations like the FreshWater Salt System have improved on the early successes to make salt water spas even more user-friendly. Continuing the benefits already listed, here’s how new salt water systems make hot tubs simpler to maintain and more rewarding to own and use on a regular basis.

7. Affordable

Thanks to a superior design and carefully selected materials, the FreshWater Salt System costs less than other chlorine generating salt systems.

8. Disposable titanium cartridges

The FreshWater Salt System uses titanium cartridges to convert salt into chlorine. They’re designed to last four months with normal spa use and can be purchased in packs of three at local hot tub dealerships, so a single pack can keep spa water clean for an entire year*.

9. No tools required

Designed for ease of use, replacing a cartridge takes just seconds. Simply remove the old cartridge right from the spa bar top, throw it away, and replace it with a new one. No tools or dealer assistance required.

10. Simple instructions

The FreshWater Salt System takes the guesswork out of hot tub water care with easy-to-read control panel prompts. The hot tub will notify you when it’s time to replace a cartridge or adjust sanitizer levels, allowing you to focus on relaxation and wellness, not chemistry.

Getting started with the FreshWater® Salt System is simple. Check out our startup guide for helpful steps.

11. Factory integration

Built into all 2019 Caldera® Utopia® Series and Paradise® Series spas, the FreshWater Salt System is pre-plumbed, meaning it requires no additional or unsightly plumbing materials. You just need a start-up kit to begin using the system. This guarantees quality, maintains the aesthetic value of your tub and helps keep the system affordable.

The FreshWater Salt System provides Pure Comfort® for hot tub owners, assuring that spa water is always clean and ready to use. Plus, by simplifying water care, you’ll be able to use your hot tub more often. Consistent hot tub use enhances the wellness benefits of hydrotherapy, reducing stress and improving mood and sleep.

*Factors such as bather load and water chemistry can impact water life. When the spa is properly maintained, a 3-pack of cartridges with the FreshWater Salt System will keep water clean and fresh for a full year. Not available in Canada.
