The newly redesigned Water Rainbow waterfall with its curved edge creates a dramatic cascade of water. It casts a brighter light on the water than ever before, adding to the calming effect and visual beauty of your hot tub.
The newly designed J-300 Signature Collection lighting system (available on select models) uses LED technology to produce more light per watt than incandescent bulbs. LED’s emit coloured light without the use of colour filters, and focus more intensely and brightly.
They also last longer and cost less to use than other types of bulbs.

Fasten-your-seat-belt jet power: standard with every J-400 Collection hot tub. Jacuzzi Hot Tubs perfected the bubbling, warm-water home spa session, but they are famous for the big, bold, hydrotherapeutic massage. The Jacuzzi PowerPro System™ drives all of the jet action, soft or strong, with a high volume, but at a low-pressure. Besides delivering versatility and power, the PowerPro System is energy efficient and durable.
Jets and Jacuzzi go way back. The jets featured in Jacuzzi hot tubs are based on the design of the first Jacuzzi jet created 50 years ago. That jet was the predecessor of today’s PowerPro jets, which deliver a 50/50 air-to-water mix that massages deeply and gently at the same time.
Technology shows its sensitive side. Different muscle groups demand different types of massaging jet action. Each of the versatile jets in the J-400 hot tubs delivers a full range of massages, from robust and stimulating to gentle and rejuvenating. Selected adjustable jets let you control the way they perform just by turning their “faces” or nozzles.
Water in motion - Jet diverter valves activate water going to groups of jets on either side of the spa, in the middle, or split the pressure between groups. They also allow you to adjust water pressure up or down, and control the flow of water to jets in the seats.
Soft feel, yet sturdy, and are generously sized with colour co-ordinated LED illumination.
The energy-wise circulation system is engineered to perform. 56-frame pumps and a dedicated circulation pump provide an entire energy-efficient system that powers the jets and the water features. The control system senses the water temperature and automatically ensures that it is controlled to the desired comfort level. The quiet-running pumps allow you to enjoy the refreshing and soothing sounds of moving water, from inside and outside the spa.
J-300 hot tubs include these unique ways to keep water clean and clear. The Circulation System and a sophisticated, yet simple, three-step process help maintain the water’s purity with fewer chemicals and less maintenance than other spas.
1. Two 60 sq. ft filters drive the ProClear filter system. One filter is dedicated to the 24 hour circulation pump, turning the water over up to 30 times each day. The second filter works during normal use for maximum purification when the water needs it the most.
2. 24 hour circulation pump operates on 5 amp (same as standard light bulb) slowly and efficiently moving water through the system. This pump is ideally balanced to work effectively with all components in the system.
3. The energy saving non-immersion heater features an ultra low watt density, energy conserving stainless steel heating element. This system allows water to pass over the heater slowly; increasing the efficient transfer of heat to water and reducing mineral build up.


Inside the ProClear filter is an in-built chemical dispenser designed to steadily dose your spa with your desired sanitiser to your preferred level. This feature eliminates the customers need to dose the spa each day, by hand, and provides a safer, more enjoyable bathing experience.
