How is the Single-Shell swim spa series different from the Original Endless Pool?

Our single-shell, molded acrylic models arrive pre-plumbed, pre-wired and do not require assembly. The modular Original Endless Pool features components that can fit through standard doorways and down stairs for installation in existing spaces.

How much do your Single-Shell swim spas cost?

We have a range of different models in this series starting at $19,900. Call our Design Representatives at 866-558-7946 for details.

How easy is it to install an Endless Pool Single-Shell swim spa?

All Endless Pool Single-Shell swim spas come pre-plumbed, pre-wired and ready to use. All you need to do is fill it with water and hook up the electricity. Should you require help with this or if you need to prepare the site we have a nationwide network of Factory Trained Installers who are available to install your Endless Pool. If you are handy, you can do it yourself. For more details, call our Design Representatives at 866-558-7946.

Where can I install an Endless Pool Single-Shell swim spa?

An Endless Pool Single-Shell swim spa can be installed indoors or outside. Outdoor spaces are particularly suitable: the model is placed in position, and you can be swimming that day. Indoor installations in existing spaces are possible if you have a large opening such as a garage door or a large patio door. Alternatively, these models can be installed in virtually any room with new construction. Our installation options include fully above ground, partially in-ground, or fully in-ground.

Can I try a pool before I buy?

Yes. Although our pools are shipped factory direct worldwide, we have a network of demonstrator pools where you can try an Endless Pool. If you would like to take a swim please contact our Design Department at 866-558-7946.

How much does it cost to operate?

The ability to enjoy all the benefits of warm water year-round, at low cost, is one of the real advantages of an Endless Pool. The operating costs are about the same as for a hot tub. Costs can be controlled by utilizing the appropriate level of insulation for your geographic location, maintaining an ambient temperature in the pool room, and keeping the pool covered when not in use, etc.

What maintenance is required?

Unlike a traditional pool, an Endless Pool Single-Shell swim spa requires very little maintenance, on average a few minutes each week to test the water and add some regular household bleach. Also, the Endless Pool cartridge filter needs to be replaced every three to six months, depending upon pool use. Every Single-Shell swim spa uses an ultraviolet water purifier to reduce the amount of chemicals needed to maintain sparkling clear water.

What about humidity for indoor installations?

Humidity is always a concern when you bring a body of water indoors. Because the Endless Pool is small in size, it is easy to control humidity by keeping the pool covered when not in use. Our Single-Shell swim spa series offers two cover options: the Watkins bi-fold cover/lifter and, for added security, the VacuSeal™ System. Both security covers can control 100% of the humidity when in place and are designed for easy of use by one person. Click Here for more on humidity.

Does the Endless Pool really work?

It really works! You really can swim or exercise in place against a current set at a speed you select, for as long as you like. No more trips to a membership pool. Imagine the convenience of being able to swim in the privacy, comfort and safety of your home anytime day or night. Because the current holds you in place, you never reach the end of your Endless Pool. This unique swim-in-place feature allows the Endless Pool to be much smaller than a conventional pool, while providing all of the benefits of a full-size pool. The Endless Pool is so carefree it even maintains your favorite water temperature automatically!

Is it difficult to keep the pool clean?

Our dual water purification system combines bacteria-killing UVC lighting with eco-friendly Ozone to tackle viral and fungal contaminants. With its 24/7 circulation and hourly water turnover, you get ease of maintenance in a fresh smelling, low-chlorine system.
The Endless Pool uses an ultraviolet water purifier to help sanitize the pool water. This system uses ultraviolet light to destroy bacteria, viruses and algae. You must still use a small amount of chlorine to oxidize the contaminants. In most installations, a cup or less of unscented household bleach after each swim is sufficient. This amount of chlorine is substantially less than the amount needed in a typical chlorinated pool.

How fast is the current?

The Original Endless Pools current can go as slow or as fast as you want with the touch of a button. At top speed, the equivalent swim would be 1:08/100 yards or a mile without turns in 20 minutes.
Our SwimCross Exercise System features a 5-speed jetted current, which adapts for most users.
We should emphasize that the swim spa is primarily a constant swimming machine, not a sprint machine. Because you never reach the end of an Endless Pool and you are swimming against a current, the swim tends to be "more concentrated" than in still water because you swim at a constant pace.

How often do I have to change the pool water?

The Endless Pool is filled with a garden hose. The water is changed every one to two years, depending upon use.

Is there architect and designer support from Endless Pools?

Our in-house staff of architects, professional designers, and engineers are available to help plan the pool of your dreams. If you can take a photo of your proposed pool site, we can send you an "After" photo with a pool superimposed on your photo. We can even provide a drawing of your proposed pool in AutoCAD or as a PDF.

Can I do water aerobics?

Yes, all Endless Pools models are excellent for aquatic exercise. We offer models with a range of depths to accommodate a diversity of sizes and uses. Our 58” deep swim spas can accommodate our optional Underwater Treadmill; that gives you both the standard water depth and the treadmill area, which is elevated by 4”.

How does the Endless Pool compare to a lap pool?

Personal lap pools are usually one lane wide, about 3'-6' deep and usually require a 50' to 75' length to satisfy most serious swimmers. The Endless Pool takes up much less space, is simpler to install (particularly indoors), easier to maintain and more economical to run than a traditional lap pool.

Is it hard to swim in the Endless Pool?

It usually takes only a few seconds to learn how to swim "against the current." Most first-time swimmers are so thrilled by seeing how easy it is that they pop up and say with a big smile, "this thing really works!"

What sizes are available?

The Endless Pool Single-Shell Series consists of multiple swim spa models. Visit our Products page to view your current options.

How does the swim current operate?

The signature Endless Pools swim current is generated by a 16" propeller inside a protective acrylic case that is driven by a hydraulic motor. The current is totally adjustable in speed from zero to a racer's pace. With the best swim current on the market, the Endless Pool can move a huge amount of water - up to 5,000 gallons a minute - under low pressure from a large opening (21"x16") producing a river-like current.
Our Swim Cross Exercise System features our jetted swim current. Specially designed for these entry-level swim spas, the current features 5 jets, 5 speeds, and minimal turbulence. When used with our swim tether, you get gentle resistance for exercise that’s as effective as it is enjoyable.

Can I get trapped in the current?

The current of every Endless Pool is confined to the center of the pool. If you want to get out of the current, all you have to do is take one step sideways out of the current into calm water. The pool has been tested by NSF and is VGB 2008 compliant to ensure that it is has been rigorously tested to prevent suction entrapment.
