The Neptune’s high-performance swim jets create a smooth, adjustable current that lets you choose your pace, from easy strokes to a challenging workout.

Two Swim Jets (Splash)

Our entry-level propulsion system uses a single swim pump and two focused jets to create a smooth, gentle current. Ideal for light exercise or simply enjoying your swim spa as an above-ground pool.

Three Swim Jets (Advanced)

Our advanced propulsion system powers 3 swim pumps and 3 focused jets, creating a stronger current that’s great for recreational swimmers or families teaching kids water confidence.

Four Swim Jets (Pro)

Engineered with 4 swim pumps and 4 precision jets, the Pro Swim Series produces an elite-level current designed for serious training and performance.

Swim Spa Layout Explained

Experience full-body relief with precision-engineered hydrotherapy. From powerful jets that target your back and legs, to dedicated neck and shoulder massage seats and deep foot jets that soothe from the ground up—every seat is designed to deliver the perfect blend of relaxation, recovery, and revitalisation.

  • Single zone Vs Dual Zone

    Single Zone Swim Spas give you one big space to swim, exercise, and relax together. Dual Zone Swim Spas add flexibility with separate swim and spa ends - each with its own temperature, so you can work out and unwind at the same time.

    Work hard, relax harder. The spa end of your swim spa is the perfect spot to unwind after a swim or workout. Slip into the soothing jets, let your muscles recover, and enjoy the ultimate balance of fitness and relaxation, all in one spa!
  • Swim End

    Make every day a swim day. The swim end of your spa is designed for all ages and abilities. Whether it’s gentle exercise, family fun, or a challenging workout, it’s always ready when you are.

Intelligently Designed for Lower Running Costs
