The Backyard Dilemma That Keeps a Lot of Arizona Homeowners Stuck
You want a pool. But a pool in Scottsdale or Gilbert means permits, excavation, six-figure costs, a multi-month build process, and a water feature that’s too cold to enjoy in January and too hot to use comfortably in July without shade infrastructure.
You also want a hot tub. But the hot tub alone doesn’t give the family the swimming and exercise space they’d actually use. And two separate products mean double the footprint, double the maintenance, and double the investment.
This is exactly the gap a swim spa fills. One installation. One water system. One maintenance routine. And a product that genuinely serves both fitness and relaxation purposes across every season Arizona offers. For homeowners in Scottsdale, Gilbert, and Mesa, the swim spa is increasingly becoming the answer that makes both problems disappear.
What a Swim Spa Actually Is, and What It Isn’t
A swim spa is a large, self-contained water unit, typically between 12 and 19 feet in length, that combines a swimming area powered by a continuous adjustable current with a heated relaxation section equipped with hydrotherapy jets.
It is not an above-ground pool with a pump attached. The current systems in quality swim spas produce a wide, smooth, laminar flow that allows continuous swimming in place, similar in physical demand to open-water lap swimming. The swimming zone is sized so that a full arm stroke completes without hitting the walls.
The relaxation section functions as a dedicated hot tub, with targeted jets positioned for shoulder, back, and leg hydrotherapy. The temperature in this section is independently maintained from the swim zone in dual-temperature models, allowing one person to swim while another soaks.
This distinction from a simple inflatable or entry-level pool model is significant. Southwest Spas and Pools carries the Sundance Swim Spas line, which represents the engineering quality that makes a swim spa genuinely useful rather than a compromise.
Year-Round Use: The Advantage Arizona’s Climate Actually Gives You
In most of the country, outdoor swim spas have a usable season. In Arizona, they don’t. The temperature is warm enough to use a swim spa comfortably for outdoor swimming 10 to 11 months of the year, and the winter months that require heating are mild by national standards.
In summer, the swimming zone can be cooled below ambient temperature and used as a refreshing counterpoint to the heat. In winter months, the heating system maintains comfortable water temperatures without the energy load required in colder climates. The result is a product that gets used, consistently, across 365 days.
For Arizona buyers who are weighing a swim spa against a traditional pool, this year-round usability is a meaningful factor. A pool in Scottsdale sits unused in the cooler months. A swim spa doesn’t.
How the Summer Heat Affects Swim Spa Use
Properly insulated swim spas like the Sundance models we carry maintain water temperature with minimal energy input even in Arizona’s summer. Many owners cool the swim zone temperature down to 82 to 86 degrees in July and August, using the spa as a cooling station after work. The insulation that holds heat in winter also slows heat absorption from the ambient air in summer, which keeps cooling costs manageable.
The Fitness Application: What You Can Actually Do in a Swim Spa
The athletic applications of a quality swim spa extend well beyond swimming strokes. Here is a representative range of what regular users incorporate:
- Continuous swimming: all standard strokes, including front crawl, breaststroke, and backstroke, against an adjustable current
- Water walking and jogging: low-impact cardiovascular conditioning with the resistance of water
- Aqua aerobics: structured movement routines using the water’s resistance for muscle conditioning
- Strength training: resistance-based exercises using the jet current or handheld equipment
- Rehabilitation exercise: movement therapy for joint conditions or post-surgical recovery
- Yoga and stretching: the buoyancy of water makes many flexibility exercises more accessible and more effective
For buyers who want their outdoor water feature to contribute to fitness goals rather than just recreation, the swim spa delivers a scope of physical activity that a traditional hot tub cannot and a pool accommodates less conveniently.
The Relaxation Section: Full Hydrotherapy in the Same Unit
The relaxation section of a Sundance Swim Spa is not an afterthought. These models are engineered with the same hydrotherapy jet architecture as the dedicated hot tub line, which means the spa end of the unit delivers genuine therapeutic benefit.
Jets are positioned for lumbar, shoulder, neck, and lower leg muscle groups. Water temperature in the spa end of dual-zone models is maintained independently, allowing it to remain at therapeutic temperatures (100 to 104 degrees Fahrenheit) while the swim zone is cooler.
For families, this creates a dynamic that works well: children swim while adults soak. Athletes recover while a partner relaxes. The physical space accommodates multiple activities simultaneously, which is something neither a hot tub nor a traditional pool can offer on its own.
Sundance Swim Spa Models at Southwest Spas and Pools
We carry three primary Sundance Swim Spa configurations, each designed for a different buyer profile.
12 Splash: The Right Scale for Smaller Backyards
The 12 Splash seats nine adults in the relaxation section and uses a 35-jet system for hydrotherapy. Its 12-foot footprint works well in Gilbert and Mesa backyards where outdoor space is more limited. The swim current is adjustable and suitable for walking and moderate swimming.
Surf 17: Built for Serious Swimmers
The Surf 17 is a 17-foot model engineered specifically for swimming performance. Its 48-jet system powers a high-volume current that supports continuous lap-style swimming at speeds appropriate for trained and developing athletes. The lounge seating configuration in the relaxation section makes it equally effective for recovery.
Stream 17: The Balanced All-Rounder
The Stream 17 shares the 17-foot footprint with the Surf but uses a different current configuration that is slightly more accessible for recreational swimmers, water walkers, and families with younger children. The 48-jet spa section delivers the same quality hydrotherapy as the Surf in a layout better suited for mixed household use.
Installation Considerations for Scottsdale and Gilbert Properties
A swim spa installation requires more planning than a standard hot tub but considerably less than an in-ground pool. Here are the key practical considerations for Arizona homeowners.
Footprint and access: A 17-foot swim spa requires a clear path from the delivery point to the installation location. Standard installations use a crane when direct access is not available. Our delivery team assesses this at the site visit prior to delivery.
Foundation: A reinforced concrete pad designed for the weight of a filled swim spa (typically 15,000 to 22,000 pounds) is required. This is a larger pour than a standard hot tub pad and should be quoted specifically. The pad also needs to be accessible from the water source and electrical panel.
Electrical: Swim spas require a 240-volt, 50-amp dedicated circuit, similar to a standard hot tub. Some models with dual heating systems require a 60-amp circuit. A licensed electrician should assess your panel before ordering.
Water care: Swim spas use similar chemistry to hot tubs but with a higher water volume. The filtration systems on Sundance models are designed to handle the load efficiently, and Arizona’s warm climate keeps the chemistry more stable than in colder regions.
Frequently Asked Questions About Swim Spas in Arizona
Is a swim spa a good alternative to a pool in Scottsdale?
For many homeowners, yes. A swim spa delivers year-round aquatic fitness, family recreation, and hydrotherapy from a single installation at a fraction of the cost of an in-ground pool. If your priority is exercise and relaxation rather than large-scale social swimming, a swim spa often delivers more value per dollar.
Can children use a swim spa safely?
Yes, with appropriate supervision. The swim zone is typically shallower than a full pool, making it more manageable for younger children. Many families use the swim spa current as a tool for children learning to swim, since the adjustable resistance allows progression at a controlled pace.
How often does a swim spa need maintenance?
Swim spa water chemistry should be tested two to three times per week, similar to a hot tub. Water changes are typically required every three to four months. The filtration systems on Sundance models are designed to handle daily use with minimal manual intervention.
How loud is a swim spa when the current is running?
Sundance Swim Spas produce a moderate ambient sound level during swim sessions, comparable to a household appliance. Many owners describe it as white noise rather than intrusive sound. Neighbors are rarely impacted at standard backyard distances.
