Colour changing mood light system consisting of:


  • 1 x 125mm 55way LED colour change Chromotherapy unit.



Structural Construction:

We have designed this model exclusively for indoor use and therefore we form the shell from our Bath Acrylic.

This has significant cost savings and is perfect for indoor use though will not withstand the high UV levels found in the outside environment.

All the other structural and performance components are the same as our Manhattan "Standard" model.

The revolutionary shock absorbing pillar supports, one piece integrated floor pan, composite cabinet and treated perimeter frame all still come as standard just like all our other models..

Shell: 5 layer composite consisting:

  • Vacuumed formed from Snow White bath acrylic

  • A second layer of ABS polymer that substantially increases the impact strength.

  • A robotically applied reinforcement layer of proprietary high density polyurethane polymer.

  • An additional thick layer of lower density polymer that provides built-in high "R2" value insulation.

  • imbedded shock absorbing mounts for the multi point reinforced "zero-stress" pillar support system


  • High strength Perimeter frame

  • High grade UV stable textured cabinet

  • Recycled formed ABS impervious floor pan

Insulation/energy management:

10mm Styrofoam insulation around the cabinet and floor pan combined with our integrated shell insulation provides a very high level of both acoustic and thermal insulation for any indoor situation.

Heat loss from the water surface is much less in an indoor situation, so we provide a floating thermal foil cover rather than the bulky external covers of the garden spas.

Thermal Barrier system consisting of:

  • 10mm double layer reflective perimeter barrier cabinet/base layers

  • 10mm polyurethane shell spray insulation

  • Electronic Overheat vents in cabinet

  • Heat capture from finned bodied pumps

  • Balboa solid state programmable controller

  • 3mm floating thermal foil blanket

Electrical supply:

240v single phase 50Hz. This powerful spa needs to be wired directly to your electricity consumer unit via an isolator switch. This is a straightforward job for any professional electrician.
