HeatSave wraps the entire shell in multiple layers of thermal protection. Each panel has a reflective insulating lining, and the acrylic shell has several layers of insulation that prevent heat loss and recycle latent heat. Touch-screen models (Maluku, Ovaka, Tinian, Kiribati, Palau) get HeatSave3, which adds a high-density foam barrier for even better retention. The result is predictable running costs year-round.

The Cayman is the most advanced swim spa in the ReefSpa range. At 19 feet, it features T3 Truwave Turbine Technology for a smooth, natural counter-swim current. Three hydrotherapy massage seats at the rear complete the experience.
The Cayman takes a different approach to swim current. Instead of river jets, it uses a T3 TruWave Turbine that pushes a wide, smooth column of water across the full width of the swim lane. The result is a current that feels closer to open-water swimming, with less turbulence and more consistent resistance.
At 580 x 228cm and 150cm deep, the swim area is generous. Six cascade waterfalls line the edges, and one turbine pump plus one massage pump keep the system simple and efficient. The Balboa control system handles speed, temperature and filtration. HeatSave insulation and a steel-braced, maintenance-free cabinet protect the unit year-round.
Built for swimmers who want the cleanest possible current in a home swim spa. Runs on a 32A supply.

Every Pulsar jet is individually adjustable for both direction and intensity. They are engineered to target specific muscle groups: neck, shoulders, back, calves and feet. You control the pressure at each position, so the massage suits your body rather than a factory default. The flagship Ovaka runs 97 Pulsar jets across its six seats.
Learn moreReefSpa uses the Balboa Spa Touch 3 control system, the most widely trusted platform in the industry. Touch-screen models give you a colour display for temperature, pumps, lighting and audio. Push-button models keep things simple. Wi-Fi is optional for app-based remote control. Holiday let models use a dummy topside overlay that restricts guest access to jets and lights only.
Learn moreEvery ReefSpa sits on a steel frame that is 250% stronger than traditional wooden alternatives. It is corrosion-protected, will not rot or warp, and provides a rigid base for decades of outdoor use. The maintenance-free composite cabinet panels look and feel like real wood but need no painting, staining or sealing.
