The J-300™ Flagship: Largest & Deepest

The J-385™ is the definitive open-seating spa. As the largest and deepest model in the collection, it accommodates up to seven people and features 49 PowerPro® jets—the highest count in the range—alongside the revolutionary new Infrared technology.

Infrared & Red Light Therapy

New for 2025. The FX-IR seat combines deep-tissue hydromassage with targeted Infrared heat to alleviate lower back pain, whilst Red Light therapy stimulates collagen to rejuvenate your skin.

Grand 7-Seat Open Layout

Space without compromise. Designed for taller bathers and large families, the barrier-free seating offers extra depth and legroom, making it the ultimate centrepiece for entertaining.

49-Jet PowerPro® Performance

The most powerful massage in the series. 49 premium jets deliver a customised experience, including dedicated wrist jets and deep-tissue calf kneading for total body recovery.

Therapeutic Foot Dome

Relief from the ground up. The central foot dome provides a powerful reflexology massage accessible from every seat, revitalising tired feet while you socialise.

Proven Energy Efficiency

Verified by UK user data. Despite being the largest model in the range, premium insulation keeps running costs low, averaging just ~5 kWh usage per day in real-world conditions.

HydroSoothe® Neck Massage

Exclusive to the J-300™ collection. A gentle, non-splashing water cascade flows over your neck and shoulders, soothing tight muscles and reducing stress without wetting your hair.

Advanced 6-Stage Filtration

Pristine water, guaranteed. The 6-stage filtration system works in harmony with ClearRay® UV technology to trap fine debris and neutralise pathogens for a safer, cleaner soak.

SmartTub® & Touch Control

Total command. Use the new intuitive touchscreen or the SmartTub® app to monitor energy, adjust temperature, and receive maintenance alerts remotely from your smartphone.
