The J508™ embodies the pinnacle of Jacuzzi® innovation – precision engineering, immersive performance and elevated design. Every detail has been carefully considered, from its refined construction and material finish to J5-exclusive User Profiles and SmartTub® connectivity, with integrated True Water™ nanobubble technology included as standard – reflecting disciplined engineering and assured design throughout.

Thoughtful jet placement ensures each position delivers purposeful hydromassage in a setting that feels considered, social and fully immersive.

Engineered to deliver the full intent of J5™ hydrotherapy within a refined open-seating configuration, the J508™ is built around depth, precision and balance.
Across the interior, a carefully calibrated mix of Jacuzzi® PowerPro® jet formations – including FX, RX, NX and VX (with rotational variants) – creates clearly defined massage profiles from seat to seat, while the central foot dome provides concentrated foot and lower-leg hydromassage that anchors the experience.
Each therapy position is designed with purpose, allowing hydromassage to feel structured, immersive and distinctly J5™ in character.
Renowned hydrotherapy in a Jacuzzi® hot tub is achieved through our Aqualibrium® formula, creating the precise balance of air and water with the ideal pump-to-jet ratio for optimal hydromassage performance.
Combining 70 years of world-leading innovation with advanced engineering, the J5™ collection showcases our most refined patented jet technology. Versatile Jacuzzi® PowerPro® jets deliver a variety of adjustable high-flow, low-pressure massage options, from deep and invigorating to smooth and restorative, allowing for targeted hydromassage exactly where it’s needed.

Through decades of engineering expertise, we have 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 J5™ hot tub is supported by a comprehensive Parts and Labour warranty, giving you complete confidence in your investment for years to come.

Features
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.
