Sundance Spa Sense™ Explained: Everything You Need to Know
When it comes to hot tubs, Sundance® Spas has long been a leader in innovation, comfort, and hydrotherapy performance. From luxurious seating designs to cutting-edge jet systems to advanced technological innovations, our brand is constantly evolving. One of the most exciting additions to our technological lineup in recent years is the Sundance Spa Sense™ Smart Monitoring System—a platform that combines integration with automation to take the work out of watercare.
Whether you're a long-time Sundance Spas owner or shopping for your first hot tub, understanding what Spa Sense™ is—and how it can transform your spa experience—is key. In this deep dive, we’ll cover exactly what Spa Sense™ does, how it works, and why it’s quickly becoming a must-have for modern spa owners.
What is Sundance Spa Sense™?
Spa Sense™ is a smart water monitoring and diagnostic system integrated into select Sundance Spas hot tubs. It's designed to take the work out of watercare by providing real-time updates, maintenance alerts, and water chemistry recommendations through an advanced mobile app integration.
In simple terms: Spa Sense™ helps you manage your hot tub from your phone, ensuring it's always clean, balanced, and ready to use while providing automatic chemistry testing and personalized reporting.
Key Features of Sundance Spa Sense™
Here’s a closer look at what makes Spa Sense™ such a powerful tool for hot tub owners:
Unparalleled Simplicity
No need for those pesky test strips and hours of research on dosing instructions. Spa Sense™ measures key parameters like chlorine, pH, and alkalinity on a daily basis, reporting them directly back to your smartphone via the SmartTub® system. Simplified testing and streamlined dosing instructions are always within reach, and easy-to-read, up-to-date results are merely taps away on your smartphone.
Technology that Speaks for Itself
Meet the smartest sensor on the market. Spa Sense™ utilizes the only sensor currently available that offers precise recommendations based on your specific spa model and water volume. Just enter your spa’s details into the SmartTub® system, including your product preferences, and you’ll receive daily personalized reports and customized dosing instructions, tailored to your individual needs. If you want to start using a new Sundance Spas product, you can merely scan it and you’ll begin to receive instant usage suggestions based on your personal preferences, directly to your smartphone.
Testing You Can Trust
It’s time you became acquainted with MICROFLUIDIX chip sensing, the only liquid-based reagent sensor on the market. This state-of-the-art microfluidics technology provides the most accurate water testing currently available, helping your maintenance and water care remain as simple as possible from day one and beyond.
Remote Monitoring and Control
Automated alerts ensure you’re always on top of your hot tub maintenance, wherever you may be. If your pH dips too low or sanitizer levels are off, the app will notify you and offer simple, step-by-step guidance to correct the issue. This helps prevent water problems before they start.
Even if you’re away from home, you can:
- Adjust the temperature
- Schedule filtration cycles
- Put the spa in vacation mode
- Receive notifications if power is lost or the spa is in distress
This is especially helpful for vacation homes or rental properties with hot tubs.
How Does Sundance Spa Sense™ Work?
Spa Sense™ relies on integrated MICROFLUIDIX sensors inside your spa’s plumbing and shell to continuously gather data. Paired with the technology of the patented SUTRO Water Monitoring System, these sensors communicate with the onboard Spa Sense™ system, which transmits the data to your SmartTub® app via a secure wireless connection.
The app then analyzes the data and delivers easy-to-understand insights—no chemistry degree required.
Example: A Day in the Life of Spa Sense™
Let’s say it’s Friday afternoon and you’re planning to soak with friends during the night. You open the SmartTub® app and check the water status:
- Sanitizer: Good
- pH: Slightly low
- Temp: 101°F
The app recommends adding a small dose of pH increaser and provides instructions. You make the adjustment and get a thumbs-up 30 minutes later. Problem solved—party on.
Benefits of Using Sundance Spa Sense™
Simplified Maintenance
Maintaining balanced water chemistry is one of the most essential yet time-consuming aspects of spa ownership. Traditionally, this involves regular testing with strips, interpreting unclear results, adjusting chemical levels manually, and hoping you’ve got the mix just right.
With Spa Sense™, these steps are automated. The system uses advanced MICROFLUIDIX chip sensing technology to test your spa water for pH, chlorine, and total alkalinity with lab-like accuracy—no guesswork, no mess. It replaces traditional test strips with precise, liquid-based reagent testing. This means:
- You no longer need to spend time manually checking water levels.
- You avoid the hassle of remembering testing schedules.
- You receive real-time, expert-backed guidance through the SmartTub® app.
Bottom line: Spa Sense™ gives you your time back—so you can spend it relaxing, not researching.

Enhanced and Consistent Water Quality
Nothing ruins a spa soak faster than cloudy, smelly, or irritating water. Maintaining consistently clean, clear water requires constant monitoring and proper dosing—something that’s often overlooked until a problem arises.
Spa Sense™ ensures:
- Consistent Monitoring: The system keeps an eye on water chemistry around the clock, providing up-to-the-minute readings.
- Balanced Dosing: Users receive precise recommendations for chemical adjustments based on the real-time condition of their water and the specific volume of their Sundance Spa model.
- Better Overall Hygiene: By avoiding swings in chemical levels, you're less likely to experience the bacterial growth, scale buildup, or foul odors that can occur with poorly maintained water.
Result: A consistently clean, refreshing, and safe spa environment every time you step in.
Healthier Soaking Experience
Improper water chemistry can lead to skin irritation, red eyes, allergic reactions, and even respiratory discomfort. Spa Sense™actively helps prevent those issues by maintaining a healthy water environment. Since the system keeps pH and sanitizer levels within ideal ranges, you’ll enjoy:
- Softer, gentler water that feels better on your skin.
- Reduced risk of irritation for sensitive users.
- Safer water for children and guests.
If health and wellness are the reasons you own a spa, then Spa Sense™ will only enhance your experience by making your water care safer and more effective.
Prolonged Equipment Lifespan
While the upfront cost of a high-tech monitoring system might seem like an investment, Spa Sense™ actually saves money in the long run.
Here’s how:
- No Overuse, No Waste: Accurate chemical dosing means you only use what you need.
- Fewer Chemical Corrections: Since you're consistently monitoring the water, you avoid the costly process of “resetting” your spa when the water goes bad.
- Reduced Water Changes: Properly maintained water can last longer, minimizing the need for draining and refilling your spa.
Protecting your spa from chemical imbalances also reduces wear and tear on your pump, heater, jets, and other components, saving on maintenance and repair costs down the line.
In short: Smart water care = smarter spending.
How Does Spa Sense™ Compare to Other Systems?
There are other smart spa systems on the market, but Sundance Spa Sense™ stands out for a few reasons:
- An Integrated Solution: Spa Sense™ is built into the spa’s system, not a third-party add-on.
- Proven Reliability: Sundance Spas has a reputation for quality and dependability that spans over four decades.
- Superior Support: With Sundance’s customer service and dealer network, help is always close by if you need it.
Some other brands offer water monitoring, but few combine it with the seamless app experience, predictive maintenance, and remote control flexibility that Spa Sense™ delivers.
