H2O 4500 Series Hot Tub

The 4500 Series is the perfect balance of space, style, and performance — designed to bring people together or create the ultimate personal retreat. With room for up to six, including two full-body no-float loungers, it’s a true crowd-pleaser that turns any garden into a haven of relaxation.

52 precision-engineered hydrotherapy jets and dual 3HP jet pumps deliver a deep, customisable massage — from gentle tension relief to powerful, invigorating therapy. Easy-to-adjust diverters let you tailor the flow exactly to your liking, so every soak feels made just for you.

The 4500 Series isn’t just about hydrotherapy — it’s about atmosphere.

Set the mood with LED waterline and underwater lighting, or unwind beneath three gracefully illuminated fountains that move in time with your favourite tunes, played through the integrated Phantom Bluetooth Audio System and subwoofer.

It’s light. It’s sound. It’s pure escape.
