I want to use aromatherapy oils in my spa. Will using these oils void my warranty?

We do not recommend using any type of oils or bath salts in your spa because they tend to gum up the filters and damage the electrical components in the spa. Using these products does not void the spa’s warranty, but any service needed to repair the spa because of damage caused by the use of non-approved chemicals is not covered by the warranty. Those can be expensive repairs, so we recommend checking with us before you use any new chemical or oil in your spa.

The first thing is to determine what spa sizes you are considering. Some spas do not offer the option of 110v service. It also depends on how you plan to use the spa. Basically, having a spa hooked up for 230v service means that the jets and the heater can operate at the same time.

With a 110v unit, the heater will not come back on until you turn off the jets. If your new spa is going to be “party central” with several people in and out of the spa over a few hours, you might be happier with a 230v hookup. If your spa is going to be a quiet refuge for one or two people who enjoy a hot water soak with no jets, then a 110v unit might be best. Also, you need to consider whether you are installing your spa indoors or outdoors and whether you plan to use it year-round. Since many different factors go into this decision, call or text us at 303-296-7727. We will be glad to provide the information you need to make the best decision for your spa enjoyment.

This question is best asked of your child’s pediatrician or other medical professional. Small children are sometimes less tolerate of exposure to hot water, so ask your doctor before allowing young children to use a spa.

Hot Spring spas carry several different certifications that ensure the spa is safe to use. Some code enforcement personnel mistakenly believe that public pools and private residential spas require the same code compliance and barrier requirements. If you have questions about barrier requirements in your community or region, contact IHT to obtain the information you need. You may also call the Hot Spring Customer Service team to get help you find this information.

Yes. We can order parts directly from Watkins, the manufacturer of Hot Spring Spas. If they do not carry the original component, a replacement component of equal or better quality will be provided. We can also provide a replacement cover for your spa that fits the corners and cover locks.


Swim spas are a great option for someone who wants a swimming pool, a spa and a home gym – all in one. Most swim spas include a jet or propulsion system that creates a continuous current. This makes it possible to swim in place. In addition to swimming, you can also use a swim spa for low-impact exercise and relaxation. In an Endless Pools® Fitness System with an optional underwater treadmill you can also run or walk without impact.

A SWIM SPA focuses on swimming, with the added benefit of spa seating (usually). When shopping for a swim spa, its important to learn about the swim current system. A swim jet system that uses air to produce force will be far more turbulent than a swim jet system that uses a boost effect to draw in more water. Learn about why SwimCross™ Exercise Systems uses a boost effect to draw in more water for a low-turbulent jetted swim.

AN EXERCISE POOL provides an environment for aquatic exercise, but it’s typically smaller and not suitable for swimming. Exercise pools sometimes include spa seating, but not always. Learn why the SwimCross Exercise Systems X200 or X500 are great alternatives to a typical exercise pool.

A FITNESS SYSTEM provides the best environment for swimming, aquatic exercise and relaxation. With the leading Endless Pools Swim Machine, the only hydraulically-run underwater treadmill, built-in anchors for aquatic fitness equipment and comfortable hydromassage spa seating, Endless Pools Fitness Systems are the ideal mix of a swim spa and an exercise pool with a beautiful style that compliments any home. Get more info here.

The Endless Pools® Fitness Systems offers four models:

  • E2000: 20-feet x 89 inches

  • E700: 17-feet x 89 inches

  • E550: 15-feet x 94 inches

  • E500: 15-feet x 89 inches

The SwimCross® Exercise Systems offers three models:

  • X2000: 20-feet x 89 inches

  • X500: 15-feet x 89 inches

  • X200: 12-feet x 89 inches

The RecSport® Recreation Systems offers two models:

  • R500: 15-feet x 89 inches

  • R200:12-feet x 89 inches

Because Endless Pools® Fitness Systems are smaller in size than a pool, maintenance is relatively simple. However, there’s still work involved. Regular care and maintenance will ultimately determine how long your Fitness System and its components will last.

Swim Spa Maintenance Considerations

Water Maintenance

This is one of the most important areas of Fitness System ownership. Your dealer will guide you through maintenance orientation, but some pointers to know:

  • Test your water with a test strip once per week, or each time the Fitness System is used

  • Dispense water care products into the water as needed, to maintain water chemistry balance

  • Change 50% of water every year, however this really depends on how often it’s used so consult with your local dealer

  • A weekly or monthly super chlorination may be required, depending on use

Filter Cycles

Your personal usage, including frequency and the number of occupants, will all determine how often to clean your filters. We recommend checking and cleaning the filters, once every two to four weeks to ensure proper filter flow.

The filter cycle can be adjusted on your control panel to run up to two times a day for as long as 12 hours per session. You have the option of changing the days, start times, and length of time.

Other Maintenance

  • Clean your Fitness System’s acrylic shell regularly with water and a soft rag or nylon scrubber — you may also want to use a Stain and Scale Inhibitor if your Fitness System has a high concentration of dissolved minerals

  • Remove and clean pillows whenever the Fitness System shell is being cleaned

  • Regularly clean the Fitness System cabinet with a mild soap and water solution

  • Rinse dirt or debris off the vinyl cover once per month.

We will provide a swim spa maintenance orientation when you purchase your Fitness System; of course, you should also consult your owner’s manual for more detailed information or call or text us at 303-296-7727.

Your Fitness system is designed for year-round use in any climate; however, if not in use or not winterized properly, extremely cold temperatures could cause damage. Additionally, outdoor Fitness Systems have weather-related considerations, and those who live in colder climates need to take extra precautions. Please call or text us at 303-296-7727 for help with proper winter use of your Fitness System.

First, you’ll need to make sure you have the space for a swim spa installation! The Endless Pools® Fitness Systems, the SwimCross®  Exercise Systems, and the RecSport®  Recreation Systems come in several models and sizes, allowing you to find the right one for your needs.

Second, consider where you’ll be installing your system.

  • Is your surface structurally sound?

  • Is it level?

  • Is there drainage?

  • Do you have enough space around it for steps or decking?

  • Do you need electrical upgrades?

  • Will it be place indoors or outside?

In 1988, Endless Pools® founder James Murdock built his first continuous current swimming machine. Nearly 30 years later, we’ve installed more than 22,000 swimming machines for people aiming to improve their health and stay active. In 2015, Endless Pools® joined Watkins Wellness and created the Endless Pools® Fitness Systems, marrying the best swim-in-place technology with the best in spa manufacturing. Together, we’re redefining swim spas.

Endless Pools® Swim Machine is unmatched amongst all other swim spa manufacturers in the industry. We’re proud to offer:

  • Superior Design: We have high standards for our Fitness Systems, and work to ensure all models are nothing short of superior. The revolutionary shell design offers a beautiful look, and the bar top flows gracefully from the spa seats to the swim-current generator. Stunning lighting, with a blue LED illumination bar, provides visual appeal at night, and the water is backlit for added elegance. You’ll be proud to show off your Fitness System in your backyard!

  • Strength: Endless Pools Fitness Systems and SwimCross™ Exercise Systems are built on a durable steel frame and ABS base pan for strength, so you can feel confident that your purchase will last for years to come.

  • Energy Efficiency: All Fitness Systems are also insulated to conserve heat, enhance the energy efficiency, and lower operating costs. The three layers of the Tri-Thermic™ Barrier System include a three-quarter inch, two-pound density EPS (Expanded Polystyrene) foam and reflective film attached to the inside of the cabinet, combined with a two-inch thick heat blanket made of high quality recycled textile fibers and foil film, attached on the inside of the steel frame. Together these materials provide maximum thermal protection.

  • Practical Features & Add-Ons: We keep the athlete in mind for all aspects of the design. Teal accents guide you as you swim, acting like a swim lane marker. In addition to the aquatic exercise accessories offered, we understand the need for relaxation as well. Perfectly-positioned spa seats and four jet types enhance your experience when you’re ready to take a breather.

Yes we do. Our underwater treadmill works by a hydraulic power unit (HPU) that pumps biodegradable vegetable oil to the treadmill’s underwater motor. This innovative design is energy efficient and eco-friendly while still providing maximum power.

The treadmill varies from a walking to running pace with a speed range of 0 to 5.5 MPH, so it can be easily adjusted for any workout level. Customers are typically drawn to the underwater treadmill because of the extra versatility and benefits it gives to their in-home Fitness System.

The underwater treadmill gives you a full-body, low impact workout. You can also create a more challenging workout by turning on the swim current, which increases water resistance for an impactful core, leg, or upper body workout. The underwater treadmill can be used as alternative for people who find that running on land is hard on their joints. It also eliminates other environmental distractions, such as traffic, other pedestrians or runners, and pavement cracks.

With an underwater treadmill as part of an in-home fitness pool, you can benefit from all of the physical and mental benefits of exercise in the comfort and privacy of your own backyard. Whether you depend on the underwater treadmill to be your full-time workout equipment or want to add it is an alternative to shake up your regular fitness routine, the benefits help motivate you to exercise more and have fun while doing it.

A swim spa heats up at about 1 to 2 degrees per hour.

“SilkBalance™ For A Relaxing Silky Spa Experience”

SilkBalance™ was formulated with a unique technology that immediately begins to adjust the water’s properties, removing excess minerals and metals, which if allowed to build up over time can be detrimental to filters and pumps. It was also formulated to be mild on your skin and contains mineral salts that leave your skin feeling silky smooth and invigorated. It does not leave a lingering odor of strong chemicals but rather a clear refreshing wonderful water scent.

Protecting Your Spa Equipment

SilkBalance™ will extend the lifetime of your spa equipment components by breaking down existing lime scale deposits the first time you use it and then continuously inhibiting further build up that comes into spas from tap water.

SilkBalance™ instantly changes the properties of the spa water by making it difficult for existing lime scale to attach itself to anything in the spa and then releases it to be captured by the filters.

Improving and Maintaining Performance

By eliminating existing limes scale deposits and continuously inhibiting the excess calcium build up it allows water to flow freely throughout the spas’ internal plumbing and jet fixtures. Stronger flowing Jets deliver the intended power of hydrotherapy to your body and muscles. Other components, such as the internal water heater will last longer.

“SilkBalance™ benefits…

  • Simple to use. It is a self-adjusting water care formula. JUST- * “Shake and Pour” one application per week! It automatically balances the water’s pH, Alkalinity, and Calcium hardness and eliminates water testing. No other spa water maintenance product works like SilkBalance for Spas. We’ll even save you time by shipping right to your door.

  • Feels great! You instantly notice the water feels different; luxuriously soft and your skin will experience a silky smooth feeling. And, no more dry and itchy skin after leaving your hot tub. Sensitive skin is free from irritation.

  • Pure and Clean. You can trust SilkBalance to provide a safe bathing environment in the Hot tub.

  • No chemical smell. It has a fresh, clean scent instead of a chemical odor and is an environmentally friendly formula.

  • Environmentally Friendly. It is safer and easier on the environment than the chemicals used in many spas. When you drain your spa, there are no precautions required.

  • Protects Equipment. It breaks down limescale deposits and inhibits the build up of excess calcium from the water, preventing problems in your hot tub.
