As an approved Jacuzzi® supplier, we can help you compare the range, plan your installation and find the right model for your home.

The J4™ Collection has been created for people who want more than a standard hot tub. It combines Jacuzzi® hydrotherapy with intelligent water care, straightforward controls and a clean aesthetic that works well in both traditional and contemporary gardens.
Features shared across the range include:
The J404L™ and J408L™ use the same core wellness and water-care technology, allowing your decision to be based mainly on available space, seating capacity and preferred layout.
The J4™ Collection features a dedicated FX-IR therapy seat that brings together hydromassage, Near-Infrared light and Deep Red Light therapy.
Two integrated Infrared emitters focus warmth around the lumbar region of the lower back, while surrounding PowerPro® jets provide adjustable massage. This combination is designed to support circulation, relaxation and muscle comfort as part of your normal wellness routine.
Rather than offering the same sensation in every position, each seat has its own carefully planned jet arrangement. You can move between targeted lower-back hydromassage, broader full-body coverage and gentler relaxation depending on how you feel that day.
True Water® uses nanobubble technology to circulate extremely small, oxygen-rich bubbles through the water. These bubbles help lift away fine contaminants, supporting clearer water and reducing reliance on traditional chemical sanitisers.
Jacuzzi® states that the system keeps the water 99.9% chlorine-free, helping to create softer-feeling water without the strong chlorine smell associated with some traditional water-care systems.
True Water® works alongside the J4™ Collection’s six-stage filtration and ProStream™ pump, helping to make regular water care easier while keeping the hot tub ready for use.
A hot tub needs to retain heat effectively if it is going to remain practical across the seasons. The J4™ Collection uses advanced insulation and intelligent heat retention to help maintain a consistent water temperature while limiting unnecessary energy loss.
An insulated cover helps reduce heat loss while the hot tub is not being used. The J404L™ and J408L™ also have a heat-pump-ready design, giving you the option to discuss a compatible installation with our showroom team.
These features are intended to support efficient year-round performance. Actual running costs will depend on the chosen temperature, frequency of use, weather conditions, electricity tariff and how the hot tub is installed.
SmartTub® technology connects your hot tub through a secure cellular connection, allowing you to monitor and control key functions remotely.
Using the SmartTub® app, you can:
This means you can check the status of your hot tub while away from home or prepare the water before you plan to use it. Smart Heat Mode can also help manage heating around your preferred routine. App access and some connected functions may require a subscription.
Jacuzzi® PowerPro® jets use a high flow of water at lower pressure to provide a controlled hydromassage. Each jet is placed to work on a particular area of the body rather than filling the shell with jets that all provide the same experience.
Depending on the seat you choose, the jets can focus on the shoulders, back, lumbar region, legs or feet. The pressure and functions can be adjusted, helping you shape each session around gentle relaxation or a more focused massage.
The ergonomic seating, lounger positions and varied jet formations make the J4™ Collection suitable for anyone looking to create a personal wellness retreat at home.
The J4™ Collection has a more architectural appearance than many traditional hot tubs. Its clean aesthetics, crisp cabinet lines and wide deck allow it to sit comfortably within a modern patio, landscaped garden or purpose-built spa area.
Interior and exterior LED lights add useful illumination after dark, while the Infinity Edge waterfall creates a smooth sheet of moving water with soft ambient sound.
A refined digital topside control panel provides direct access to temperature, jets, lights and other everyday functions. The interface is clear and straightforward, so you can make adjustments without interrupting your time in the water.
The J404L™ is the most space-efficient model within the Jacuzzi J4 Collection. It seats three to four people and is suited to couples, smaller households or gardens where space needs to be used carefully.
Its compact footprint does not mean losing the main J4™ features. The J404L™ includes lounge seating, Infrared + Red Light therapy, True Water®, SmartTub® control, PowerPro® jets and advanced insulation.
It is likely to suit you if you want:
The J408L™ is designed for five to six people and combines open seating with a full-body lounger. Its larger shell provides more room for families, couples who enjoy entertaining or anyone who wants a wider choice of hydrotherapy positions.
The upright seats target different areas of the back and shoulders, while the lounger provides more continuous massage across the body. Dedicated footwell jets add focused hydromassage for the feet.
It is likely to suit you if you want:
The J404L™ is officially listed for three to four people, while the J408L™ accommodates five to six people.
