WhatSpa? Verdict

New for 2025, the Onyx from Platinum Spas’ Premium Range is a powerful and stylish five-seater designed for serious hydrotherapy fans. With two luxurious loungers and three comfortable bucket seats, it’s perfect for families who want both space and performance. Four two-horsepower pumps drive a high-pressure jet system that delivers a deeply invigorating massage, while water features and LED lighting add to the ambience. The Onyx also includes a Bluetooth® sound system and optional Wi-Fi app to control your spa from anywhere in the world. A premium bather experience from top to bottom. Top kudos!
