The Jacuzzi® J-408L™ Hot Tub (5-6 person) features our exclusive Infrared + Red Light therapy system, integrating targeted Infrared heat into a dedicated therapy seat to complement powerful hydromassage. The J4™ Collection utilises two integrated Infrared emitters, focused on the lumbar region to deliver concentrated warmth to the lower back, while surrounding PowerPro® jets provide adjustable massage across the body.
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:
- Pain relief: Helps increase circulation to support muscle and joint comfort.
- Improved skin health: Encourages collagen production and skin elasticity.
- Repairing properties: Supports natural tissue repair and cellular renewal.
- Wellbeing: Promotes relaxation, improved mood and better sleep quality.
- Improved range of motion: Helps muscles feel looser and more flexible.
- Regeneration: Encourages healthy cellular activity and energy production.
The Jacuzzi® J-408L™ Hot Tub (5-6 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 our revolutionary Infrared and Red Light Therapy system, designed to work in harmony with hydromassage for a deeper, more restorative soak. Targeted light gently warms the lower back, supports circulation and helps ease deep muscular tension. Seamlessly integrated into the dedicated therapy seat, it enhances traditional hydrotherapy with the proven benefits of therapeutic infrared and red light.
True Water® System
True Water® transforms the way spa water feels and performs. This groundbreaking nanobubble technology releases billions of ultra-fine, oxygen-rich bubbles that continuously refresh and clarify the water, keeping it 99.9% chlorine-free. The result is water that looks clearer, feels softer on the skin and remains beautifully inviting, with significantly reduced reliance on traditional chemical sanitising.
Full-Featured Modern Design
The J4™ collection blends contemporary design with purposeful engineering. Clean, sculpted lines, premium finishes and ergonomically contoured seating create a spa that feels both striking and welcoming. Every element, from precision jet placement to refined detailing and integrated lighting, has been carefully considered to deliver comfort, performance and visual impact.
SmartTub® System
Patented SmartTub® technology brings intelligent control to spa ownership through the SmartTub® subscription. Adjust temperature, lighting and hydromassage remotely, monitor performance and receive real-time notifications wherever you are. Seamless integration between the app and the spa’s topside control ensures smooth, responsive operation, giving you greater convenience and reassurance.
Digital Topside Controls
An intuitive, refined digital topside control panel provides access to your spa’s core features. The clear, modern display makes it easy to manage temperature, jet functions and lighting with precision. Designed for simplicity and reliability, it allows you to tailor each session effortlessly while maintaining the clean aesthetic of the J4™ collection.
Infinity Edge Waterfall
The Infinity Edge waterfall introduces a distinctive design feature and a calming sensory layer. A smooth, illuminated sheet of water flows gracefully into the spa, creating gentle movement and a soft, ambient sound. Integrated lighting enhances the effect, adding depth and atmosphere that elevate the overall experience.
