Spectra Lights
Transform your hot tub into a stunning centrepiece with the magic of Spectra Lights. With 8 different colour options available, either choose one to fix your mood or allow the colours to rotate as you immerse yourself in these stunning visual effects illuminating the interior of the spa, control panel and footwell.

Designated Step
All Earth Spas have been designed with a flat internal step. Combined with added tread, this feature allows a safer and easier passage when entering and exiting your spa.

LED Laminar Water Feature
Sit back, relax, and let all your troubles trickle away with the stunning LED laminar three-way intersecting waterfall feature. Either enjoy on full blast alongside the activated jets or simply switch to tranquillity mode and unwind in peace.

Reflective Foam Insulation
Designed to optimise energy efficiency, the inside cabinet of the Mariana features several layers of foam insulation, covered by a layer of foil. This not only throws back the heat generated from the pumps and heaters, but also reuses the same energy to heat the cabinet and water in the tub repeatedly. Simultaneously, any external cold air trying to penetrate the mechanics of the spa is reflected away.

Interlocking Cabinet
Strong, lightweight and durable, Earth Spas cabinets are built with the highest quality materials, designed to withstand continual exposure to the elements. Featuring a flush interlocking design, this produces the ultimate airtight, sealed environment within the spa, maximising the use of all energy created.

85 Hydrotherapy Jets
Strategically positioned to target the whole of the body, Earth Spas invigorating hydrotherapy jets are featured in the hybrid lounger, both deep bucket seats and both side seats. Each seat features a different jet configuration to allow a well-deserved deep-tissue massage, no matter which area it is that you wish to target.

Deep Blue Sounds
Earth Spas’ state-of-the-art Deep Blue Sound system with integrated Bluetooth allows you to create the ultimate atmosphere. Featuring two speakers alongside a subwoofer for extra bass, this system is sure to set the mood, whether you are enjoying a quiet night alone or hosting.
