While you may know that salt systems are available for swimming pools, did you know they’re also available for hot tubs?
At Energy Center Manhattan Pool, we appreciate the benefits of saltwater hot tubs and know they can help you relax and enjoy your wellness routine without spending too much time on maintenance.
In this article, we look at what you need to know about saltwater hot tubs to make an informed decision.
What is a Saltwater Hot Tub?
Unlike traditional hot tubs that use chlorine or bromine to sanitize the water, saltwater hot tubs utilize a salt system to generate natural chlorine.
Combining the soothing benefits of warm water therapy with advanced water care technology, saltwater hot tubs offer a luxurious and simplified spa experience.
But what exactly makes them so special, and why are so many homeowners making the switch?
Here’s what you need to know about saltwater hot tubs, especially when considering models like the ones we carry from Hot Spring® Spas.

Meet the FreshWater® IQ System
The FreshWate® IQ System combines two innovative technologies, the FreshWater Salt System and Hot Spring Spa’s Smart Monitoring System.
FreshWater IQ is a smart, in-line water care system that automatically tests your spa water and displays clear instructions to simplify water maintenance.
Now, you can tell at a glance when chemicals are needed. This takes the guesswork out of keeping your spa water balanced and ready to enjoy.
The FreshWater® IQ System converts salt into chlorine, maintaining clean, fresh-feeling water without the harsh effects often associated with chemical sanitizers.
The result? You get crystal-clear water that feels softer and gentler on your skin, eyes, and hair.
(Made for Hot Spring Spas, FreshWater IQ is available on Highlife® Collection and Limelight® Collection spas.)

Enjoy Simplified Water Care
One of the standout advantages of a saltwater system is its ease of use. Traditional hot tubs often require frequent testing, adjusting, and adding chemicals to maintain balanced water chemistry.
Hot Spring’s FreshWater® IQ system takes the guesswork out of water care.
This smart technology automatically monitors your hot tub’s water quality, tests the water every hour, and provides alerts when it needs attention. This means you can spend more time enjoying your hot tub and less time worrying about maintenance.

Benefit from Softer, Natural-Feeling Water
The biggest difference users notice is how the water feels.
Saltwater hot tubs deliver a more natural, silky-smooth soaking experience. The absence of heavy chlorine reduces skin irritation, dryness, and that familiar “pool chlorine smell.”
Saltwater hot tubs are free from chloramines, a potentially irritating byproduct produced in hot tubs when chlorine interacts with ammonia or other substances.
If you have chloramine sensitivity, a saltwater hot tub system is a perfect solution.
So, whether you are recovering from a workout or simply looking to relax after a long day, the gentler water enhances your comfort and relaxation.
Experience Improved Health & Wellness Benefits
Hydrotherapy is already known for reducing stress, easing muscle tension, and improving sleep quality. Saltwater hot tubs take this a step further by offering a more pleasant and rejuvenating soak.
The water’s softness can also help reduce flare-ups for people with sensitive skin or conditions such as eczema. Plus, continuous clean water contributes to a healthier spa environment overall.
In addition, saltwater increases the buoyancy of the water. Many people find this helps them relax better.
Have Longer-Lasting Water
Another reason homeowners love saltwater systems is their ability to extend the life of the water. Traditional hot tubs may require draining and refilling every three to four months to keep the water fresh.
With the FreshWater® Smart Salt System, water can stay clean and balanced for up to a year with normal use. This means you use less water and spend less time on maintenance.
Benefit from Cost Savings Over Time
Although saltwater hot tubs can carry a higher upfront investment due to advanced systems like FreshWater® IQ, they can save you money in the long run.
You’ll spend less on chemicals and water because you aren’t regularly draining and refilling your hot tub. Additionally, Hot Spring® spas are designed with energy efficiency in mind, further reducing your ongoing operational costs.
Appreciate the Eco-Friendly Approach
Reducing chemical usage and conserving water contribute to a more eco-friendly spa experience. Hot Spring®’s saltwater hot tubs help limit your environmental impact while still providing premium hydrotherapy.
Their Energy Smart® system further enhances sustainability by improving insulation and heat retention. Your water stays warm and ready while saving energy.
Experience Exclusive Hot Spring® Features
Hot Spring® takes salt water hot tubs to the next level by integrating the FreshWater® Smart Salt System directly into many of their models. In addition to the salt system, Hot Spring® spas offer:
- Advanced Filtration: 100% of the water is continuously filtered, ensuring superior water clarity.
- Legendary Massage Jets: Strategically designed jet systems offer targeted hydrotherapy for deep muscle relief.
- Smart Monitoring Technology: The FreshWater® IQ system provides real-time feedback and guidance via the spa’s control panel, streamlining spa management.
