Developed in collaboration with medical experts, Jacuzzi® Infrared and Red Light therapy is designed to maximise the clinically supported benefits of infrared treatment.
These benefits include:

The Jacuzzi® J-509™ Hot Tub (8-9 person) delivers a deeply immersive hydromassage experience centred around its dual side-by-side loungers, creating focused full-body coverage. Carefully positioned Jacuzzi® PowerPro® jets target the back, shoulders and legs with controlled intensity, while dedicated reflexology jets in the footwell enhance lower-body stimulation.
A calibrated blend of FX, FX-R, MX and RX jet formations works across key muscle groups to produce a high-volume, low-pressure massage that feels smooth on the surface and purposeful in delivery.
At the core of every Jacuzzi® hot tub is our Aqualibrium® formula, balancing air and water through the ideal pump-to-jet ratio to ensure hydromassage remains powerful, consistent and refined.
Combining 70 years of world-leading innovation with advanced engineering, the J4™ Collection showcases patented Jacuzzi® jet technology designed for precision and reliability.
Hydrotherapy benefits include:
- Muscle relaxation: Helps ease tension and muscular stiffness.
- Joint comfort: Supports reduced impact on joints during movement.
- Improved circulation: Encourages healthy blood flow.
- Stress reduction: Promotes relaxation and overall wellbeing.
- Better sleep: Supports improved sleep quality.
- Mobility support: Helps maintain flexibility and range of motion.
- Skin cleansing: Warm water immersion helps open pores.
- Reduced muscle tightness: Supports post-activity comfort.
- Mental clarity: Encourages focus and relaxation.
Through decades of engineering expertise, we’ve refined our approach to creating the most energy-efficient hot tubs available today. By combining advanced control systems, SmartSeal™ multi-layer insulation and precision manufacturing, Jacuzzi® continues to set the benchmark for energy-saving hot tubs.
Unlike other brands, Jacuzzi® can accurately provide estimated average running costs for each model using exclusive SmartTub® technology, based on real-world usage data.
All Jacuzzi® hot tubs undergo rigorous testing by the California Energy Commission (CEC), which has found that, on average, they perform 22% more efficiently than the strict standards they set out.
Using our SmartTub® app, we gather anonymised real-world usage data showing that the average Jacuzzi® UK customer consumes approximately 5 kWh per day – equivalent to a family of four taking a 10-minute shower daily.*
*All °C temperatures are rounded to the nearest whole degree. This information was collected over two years from UK Jacuzzi® hot tubs connected to SmartTub® energy monitoring. The data shown represent the median and are based on the recorded sample size.
Built to the highest standards of quality and durability, every J4™ hot tub is supported by a comprehensive Parts and Labour warranty, giving you complete confidence in your investment for years to come.

Infrared + red light therapy
Experience the next evolution of wellness. Four precisely positioned light panels work in harmony with soothing heat to gently penetrate deep into the body, helping to ease muscle tension, support circulation and promote natural rejuvenation. Set within the dedicated therapy seat, this advanced feature transforms every soak into a restorative, full-spectrum experience that goes far beyond traditional hydrotherapy.
True Water® System
True Water® redefines how spa water should feel. Using advanced nanobubble technology, it infuses the water with billions of ultra-fine, oxygen-rich bubbles that continuously refresh and clarify – keeping it 99.9% chlorine-free. The result is beautifully clear water that feels softer on the skin, smells fresher and remains inviting day after day, with significantly reduced reliance on traditional chemicals.
Immersive Experience Modes
Five immersive experience modes bring together hydromassage, lighting and therapeutic features in perfect balance. Each mode is expertly composed to create a distinct atmosphere for calm, relief or renewed energy. With a single touch, the spa adjusts around you, delivering a seamless, fully coordinated session designed to feel considered, refined and deeply restorative.
Personalised for Each User
Dedicated user profiles allow each person to save their preferred jet intensity, lighting ambience and therapy settings, creating a truly individual experience every time. With one touch, your ideal session is ready before you step in, while SmartTub® insights help you refine and perfect your routine over time.
Exclusive J5™ SmartTub® System
Reserved for the J5™ collection, the most advanced SmartTub® subscription brings a new level of intelligent control to your spa. Select immersive modes, manage user profiles and monitor therapy usage with precision. Real-time connectivity keeps you informed wherever you are, while enhanced performance insights give you greater command over energy efficiency and day-to-day operation. It’s connected control, elevated to J5 standards.
Digital Topside Controls
The J5’s redesigned digital topside control is crafted for clarity and confidence. Its refined, high-resolution display offers intuitive navigation across temperature, jets, lighting and therapy settings from a single, elegantly integrated interface. Responsive and beautifully executed, it ensures every adjustment feels immediate, precise and sophisticated.
Illuminated Dual Waterfall
Twin illuminated waterfalls introduce a striking visual centrepiece and a calming sensory layer to your spa. Broad, glass-like sheets of water cascade smoothly into the spa, accompanied by a gentle, tranquil sound. Subtle lighting enhances the movement, creating depth and atmosphere that elevate both the design and the overall soaking experience.
