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 Sumatra brings the warmth of its namesake to your Hampshire garden. A well-rounded ReefSpa model with generous seating and Pulsar jets that deliver deep, satisfying hydrotherapy. Built on steel, backed by a 5-year frame warranty.
The Sumatra is a five-seat plug-and-play hot tub that runs from a standard 13A household socket. No electrician, no dedicated circuit. Plug it in, fill it up, wait for it to heat. Three upright seats and two full-length loungers give the whole family somewhere comfortable to sit.
One of the two loungers is shorter, designed so smaller adults or teenagers can lie flat without sliding forward. 43 Pulsar jets target shoulders, back, legs and feet. HeatSave2 insulation and a steel-braced, maintenance-free cabinet keep running costs manageable on a 13A supply.
The easiest route into a proper hydrotherapy hot tub. No trenching, no rewiring. Just a garden, a hose and a plug socket.

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.
