11 benefits of a hot tub with a salt electrolysis water treatment system
To keep the water clean, the salt systems of a hot tub automatically generate chlorine from the small quantities of salt dissolved in the water. This method is far more efficient than adding chlorine manually every week. But the advantages do not stop there. Below are the 11 most important benefits of hot tubs with a salt electrolysis water treatment system, according to customer experience, and the reason why the latest innovations make the systems easier to use than ever.
Hot tubs with a salt electrolysis water treatment system are gaining popularity as customers look for the most natural ways possible to improve their health and wellbeing. Compared with the chemicals found in traditional chlorine-based systems, salt water hot tubs offer a gentler, more relaxing spa experience. What is more, they are also easier to maintain.

The many benefits of hot tubs with a salt electrolysis water treatment system
1. Improved wellbeing
Salt water has a greater density than water without salt, which promotes buoyancy. Increased buoyancy reduces the weight of gravity on the joints and muscles, easing tension while lifting body and mind. Just 20 minutes of daily hot tub use can turn muscle tension into comfort, calm a restless mind and improve your general state.
2. Fewer chemicals
Salt water systems constantly monitor the chlorine level in the water, thus generating only the amount of chlorine needed. This means that fewer chemicals end up in the water, extending the period of use before the next water change. In addition, the water stays much cleaner and clearer compared with water sanitised using a traditional system.
3. No chlorine smell
Salt water purification systems eliminate the „chlorine smell” that lingers in some pools and hot tubs. The smell is caused by residual chemicals in the water due to inconsistent manual chlorine dosing. Hot tubs with a salt electrolysis water treatment system maintain a constant chlorine level that removes impurities. No chemical residues, no smells!
4. Less irritation
Fewer chemicals also means that salt water spas are less likely to irritate the skin and eyes. With a gentler overall experience, you can relax fully and enjoy all the wellness benefits without any discomfort.
5. Fewer drainings
Hot tubs with a salt-based water treatment system – such as the new FreshWater® Salt System – can be emptied as rarely as once a year, compared with those using traditional chlorine-based sanitising systems, which require draining three or four times a year. This significantly reduces the time spent on maintenance and gains you precious moments to fully enjoy your hot tub.
6. Saving water
Because hot tubs with a salt system require fewer drainings and refills compared with traditional hot tub filtration systems, they use less water. This means that users of hot tubs with a salt electrolysis water treatment system can enjoy the wellness benefits while saving a limited resource.
Hot tubs with a salt electrolysis water treatment system are easier to use
Salt systems for hot tubs have been on the market for several years and successfully sanitise the water with a minimum of chemicals. But one of the most recent innovations, the salt electrolysis water treatment kit called the FreshWater Salt System, has made salt water spas even simpler to use. In addition to the benefits already listed, here is how the new salt water systems make spas even easier to maintain and use.
7. Affordable price
Thanks to its superior design and carefully selected materials, the FreshWater Salt System kit costs less than other chlorine-generating salt systems.
8. Replaceable titanium cartridges
The FreshWater Salt System uses titanium cartridges to convert salt into chlorine. They are designed to last four months with normal spa use and can be bought in sets of three, so that a single set can keep the water clean for a whole year.*
*Factors such as the number of users or the chemical composition of the water can influence how long the water lasts before it needs changing. With adequate hot tub maintenance, a pack of 3 cartridges together with the FreshWater Salt System will keep the water clean and fresh for a whole year.
9. No tools needed
Designed for easy handling, replacing a cartridge can be done in just a few seconds. Simply remove the old cartridge from the top of the spa, throw it away and replace it with a new one. No tools or technical assistance from a dealer required.
10. Simple instructions to follow
The FreshWater Salt System offers a simple way of maintaining the hot tub water by displaying easy-to-read prompts on the control panel. The hot tub will tell you when a cartridge needs replacing or the disinfectant level needs adjusting, giving you the chance to focus on relaxation and wellbeing rather than on water chemistry.
The basics of the FreshWater Salt System are simple. Consult the start-up guide for easy steps to follow.
11. Factory pre-assembled
Integrated into all the Caldera® Utopia® and Caldera® Paradise® spa series, the FreshWater Salt System is pre-assembled, with no additional or unsightly plumbing required. Only a start-up kit is needed to begin using the system. This guarantees quality, preserves the aesthetic value of your tub and keeps the cost of maintaining the system affordable.
The FreshWater Salt System delivers the Pure Comfort® experience to spa users, giving the guarantee that the water is always clean and ready to use. In addition, by simplifying water maintenance, you will be able to use the hot tub more often. Consistent use of a hot tub increases the wellness benefits of hydrotherapy, reducing stress and improving mood and sleep.
