The Story
The Multi-Award Winning Compact Retreat
Voted 'Best Buy' by WhatSpa? for four consecutive years and GQ's 'Best Hard-Shell Hot Tub'. The J-335™ combines a compact footprint with a therapy lounger and the revolutionary new Infrared technology.
Infrared & Red Light Therapy
New for 2025. The FX-IR seat fuses deep-tissue hydromassage with targeted Infrared technology to relieve lower back pain, whilst Red Light therapy stimulates collagen to rejuvenate your skin.
Compact ProAir™ Lounge
Big therapy, smart space. This innovative compact lounger targets your back, wrists, and legs with bubbling BX jets, delivering a full-body massage without sacrificing seating for guests.
42-Jet PowerPro® Performance
Experience the power of 42 premium jets. Featuring spiralling FX jets for the mid-back and adjustable PowerPro® jets, this system delivers a high-flow, low-pressure massage that is never itchy.
Proven Energy Efficiency
Verified by UK user data. Thanks to superior insulation and SmartTub® monitoring, the J-335™ is incredibly efficient, averaging just ~4 kWh usage per day over a 2-year tracking period.
Award-Winning Design
Choose with confidence. Recognised by both industry experts and lifestyle editors, the J-335™ is celebrated for its perfect balance of size, ergonomics, and hydrotherapy performance.
HydroSoothe® Neck Massage
Exclusive to the J-300™ collection. A gentle, non-splashing water cascade flows over your neck and shoulders, melting away stress and tension without wetting your hair or face.
Advanced 6-Stage Filtration
Crystal clear water made simple. The 6-stage filtration system works in harmony with ClearRay® UV technology to neutralise pathogens and trap debris more effectively than standard filters.
SmartTub® & Touch Control
Total control at your fingertips. Manage your settings via the new intuitive touchscreen or use the SmartTub® app to monitor energy and temperature remotely from your smartphone.
