Getting your Spa water back to pristine condition - and keeping it there...

In order to effectively maintain the optimal water chemistry & pH, our experience tells us your Spa needs to be checked and balanced ~every 2 weeks - our team includes all water checks, filter cleaning, and system operation testing with each visit.

Has it been a while since you used your Spa? Did last weekend's 'Chillin & Grillin' party wrap up with 12 people in a 6 person Hot Tub? Let us take the system from Party back to Therapy with our RepHresh program for your Spa, which we perform based upon water level readings.
Our team will source, ship, store & install the exact type of filter needed for your Spa (and due to our national purchasing power, we are typically able to do all of this for less than the filter retail price you'd pay!)

TheraSpa has designed & implemented water chemistry programs specifically tailored for rental properties to insure your tenants are happy and your bottom line is secured.

TheraSpa Service Group combines our knowledge of Water Chemistry & focus on Wellness to design our company's unique Spa Operation & Maintenance plans.
Most standard Spa maintenance practices utilize:
The resulting product provides limited physiological value to our bodies – and in certain cases, ends up doing more harm then good.
Our team has over 28 years of experience in Water Chemistry specific to high-temperature applications, allowing us to effectively transition ineffective & unsanitary hot tubs to Therapeutic Spas.
We proudly serve as the largest & top ranked Water Care Service Provider in the Southwest, having established our headquarters in Scottsdale, AZ.
In February 2026, TheraSpa will be launching in both Henderson, NV & Las Vegas, NV to proudly serve the Hot Tub & Spa communities there, just as we have in Arizona since 2019!!

Our company conducts Spa & Hot Tub Water Maintenance & Service to keep Spas operating at optimal pH & overall water chemistry levels.
Proper monthly water maintenance & service helps to deliver consistent hydro-therapy to users of all ages, with varying degrees of therapy needs - from avid fan to professional athletes, and everyone in-between. Imagine having access to a massage therapist 24/7, just steps into your backyard -
a well-tuned Spa can be exactly that.
TheraSpa Service Group also has the technical expertise on hand to transition standard hot tubs to TheraSpa Certified Spas with our RepHresh Program, which can be accomplished in as little as 48 hours
Please reach us at wellness@theraspaservicegroup.com if you cannot find an answer to your question.
The terms hot tub and spa are often used interchangeably, but technically a hot tub is a small pool of heated water, while a spa usually has jets for massage and hydrotherapy.
(Good news is we can service both!)
Spas require regular cleaning, balancing of chemicals, and monitoring of water levels and circulation - based upon standard bell curve usage of a Spa, ~2 weeks is the optimal interval for formal water chemistry balancing, filter cleaning, and system checks that balances water maintenance with cost for our customers (i.e. keeping cost low while maintaining high quality spa water).
It is also recommended to have a water exchange & internal plumbing flush every 6 months at the latest (we call this a Spa Rephresh). Why 6 months? Industry standards state that at this stage, the culmination of skin cells and oil, lotions, hairsprays, detergents, and residual chemicals congealing in hot water will start to impact the ability for the Spa to truly provide therapeutic value.
The TheraSpa Team does it a little differently, as we recognize each customer's usage profile varies; we track the water health, TDS levels, and saturation points with every visit to determine the optimal point to exchange the water via a Spa Rephresh. After a number of service intervals, where chlorine, shock, etc is being added to the water, the Saturation Point will occur where the water can’t hold the chemicals anymore and needs to be replaced with non-saturated water. (Spa RepHresh’s are similar to an oil change for your car, or a deep clean for your grill) .
Nothing! Another benefit of our Wellness program is how all actions are governed by tracked data - including the optimal window for when your Spa RePhresh should be scheduled; your monthly service manager reviews your TDS each trip, and when your water is approaching the Saturation threshold, a notice is passed to your Spa RepHresh Manager & Customer Integration Team to reach out to coordinate the water exchange workings (i.e. you don’t need to keep track of it, we will do that for you)
1. Don’t wash your swimsuit every time you use it; instead, run your swimsuits under cold water and allow to air dry. This minimizes the introduction of detergent into your Spa water
2. Minimize usage of lotions, hair products et al when using your Spa (it is optimal to rinse off before entering your Spa to, again, minimize introduction of these chemicals into your water)
3. Run your Spa for a full 15 minutes (or the equivalent of a filter cycle) when you use it – this both runs the water through the filter cycle and allows enough time for the warm water to bring its intended benefit
4. Allow your Spa to vent during the day when we see 105+ degree days (higher ambient temperatures = variant effects on the chemical reaction process = quicker timeframe for water to become imbalanced)
5. Add the chemicals your Monthly Service Manager leaves for you during the week TheraSpa isn’t on site; these will be pre-measured for you, all you need to do is remember to add them to the water (no additional charge for bi-monthly customers for chemicals).
