Advanced PowerPro® Hydrotherapy
The J-375™ incorporates specialised FX, MX and PowerPro® therapy seats, each engineered to provide a distinctive style of hydromassage.
Strategically positioned jets target areas including the neck, shoulders, back, legs and feet. Adjustable PowerPro® jets allow users to personalise their massage, while FX and MX jet configurations provide varied rotational, pulsating and broader massage sensations.
The result is a comprehensive hydrotherapy experience with multiple seating positions designed to target different areas of the body.
ProAir™ Full-Body Lounge
One of the defining features of the J-375™ is its extended ProAir™ Lounge. Exclusive to selected J-300™ lounger models, this ergonomically sculpted seat provides hydromassage from the upper body through the legs and feet.
Targeted PowerPro® jets combine with pulsating FX rotational jets and exclusive bubbling BX jets to provide a varied full-body massage experience. The generous length of the J-375™ lounge makes it particularly comfortable for taller users who want to fully stretch out and relax.
HydroSoothe™ Head Massage Pillow
The J-300™ HydroSoothe™ head massage pillow creates a gentle cascade of water over the neck and shoulders without splashing or spraying.
Combined with surrounding hydromassage jets and the soothing sound of flowing water, it creates an immersive relaxation experience designed to help you switch off and unwind.
Dedicated Foot Hydrotherapy
A jetted foot dome positioned at the base of the spa completes the full-body hydrotherapy experience. Carefully positioned jets provide targeted hydromassage for tired feet while allowing users seated around the spa to enjoy additional therapy.
The Jacuzzi® Aqualibrium® Experience
Renowned Jacuzzi® hydrotherapy is engineered around the patented Aqualibrium® formula, carefully balancing air and water with precisely engineered pump-to-jet ratios.
This allows PowerPro® jets to deliver high-flow, low-pressure hydromassage that feels powerful while remaining comfortable against the body. Different jet designs provide a range of massage sensations, from stimulating rotational movement to gentler, more soothing hydromassage.
Drawing on more than 65 years of Jacuzzi® innovation, the J-300™ collection incorporates advanced patented jet technology designed to deliver a personalised hydromassage experience.
