All three variations come with a factory fitted BlueTooth Stereo System, including 2 waterproof speakers as standard. They also all have a multi coloured LED lighting package. With a main underwater light and smaller LED spot lights around the waterline. Finally a set of 4 lighted waterfall jet fountains which will look stunning at night time. The SL (single lounger) and the DL (double lounger) versions have a total of 36 hydrotherapy jets. Furthermore each option has a varied selection of seating positions. All the spas have a ABS base, steel subframe and a Thermal Insulation Pack inside the cabinet. Combine this with the Thermal Hard Cover and the heat loss is reduced to a minimum. Therefore reducing the running costs of the spa. The cabinet is maintenance free and being manufactured from recycled plastics is a bonus.
