Caldera Spas Marino Hot Tub Review

Posted by Alex Clamp in on 1st July 2026

Watch our 2026 full review of the Caldera Spas Marino, a mid-range six-seater in the Vacanza Series, and now an incredible 12-time WhatSpa? Best Buy Award winner.

In this experience-led review, Dave explores the Marino’s clean, modern design, from its EcoTech™ cabinet and subtle interior lighting to its practical layout and family-friendly footprint.

With 35 adjustable jets powered by dual ReliaFlo pumps, the Marino delivers strong, consistent hydrotherapy across a range of seating positions, including a comfortable full-body lounger and well-balanced upright seats. The simple, no-diverter setup ensures every seat benefits from equal jet power, making it a great option for social use as well as relaxation.

On the tech side, the FreshWater Salt System offers a low-chemical, softer-feeling water experience, while the optional smart app connectivity allows you to control temperature, jets, and maintenance schedules remotely. Combined with a dedicated circulation pump and efficient filtration, it’s built to keep water care simple and convenient.

Add in industry-leading efficiency, with CEC-certified performance and full-foam FiberCor® insulation, and the Marino delivers impressively low running costs for a spa of this size.

But does it still deserve its long-standing reputation in such a competitive market? Watch the full review to see our no-nonsense WhatSpa? verdict.
