    H2X Fitness Therapool 15 – Space to Exercise, Relax and Enjoy

    The H2X Fitness Therapool 15 is the largest model in the Therapool Series, offering an expansive open-water area for exercise, relaxation and family fun. Designed as a versatile, year-round alternative to a traditional swimming pool, it allows you to enjoy the benefits of water from the comfort of your own garden.

    Two powerful Flow Stream jets create continuous resistance for aquatic exercise, water walking and gentle swimming. The included H2Xercise™ Fitness System adds even more variety, with rowing equipment and resistance tubing for effective low-impact strength and full-body workouts.

    After exercising, relax in the contoured therapy seating and enjoy targeted hydrotherapy from 28 stainless-steel jets. The adjustable water temperature means the Therapool 15 can be used for energising workouts, soothing recovery or simply unwinding with family throughout the year.

    With its generous exercise area, energy-efficient insulation and heat-pump-ready design, the Therapool 15 combines the versatility of a pool with the comfort and hydrotherapy of a premium spa.

    Why Buy American? Why Master Spas?

    Every Master Spas hot tub we sell is designed and built at their own American factory — real American manufacturing, not just an American badge. Here's what that actually means for you.

    Fort Wayne, IN

    Headquarters & manufacturing home

    45 Acres

    State-of-the-art manufacturing campus

    Designed & Built

    Engineered and assembled in the USA

    No. 1

    Largest portable spa manufacturer in the world

    Genuinely American-designed and built. Master Spas is the world's largest portable spa and hot tub manufacturer, engineering and assembling every spa at its own 45-acre campus in Fort Wayne, Indiana. As with most manufacturers, some individual components are sourced globally — but the design, engineering, assembly, and quality control all happen in-house, in America.

    That matters: every spa is built and tested under one roof, to consistent American manufacturing standards, rather than outsourced to third-party assembly. It's also why Master Spas hot tubs meet the strict CEC (California Energy Commission) efficiency standards few manufacturers can achieve.

    As an official UK retailer, we bring that same genuine American design and build quality to your garden — at a price that reflects buying direct from an authorised dealer, not an import markup.

    An incredible built in sound system that’s fully controllable from the easy to use remote control. With built in speakers and a subwoofer you can easily connect your smartphone or tablet via Bluetooth and enjoy listening to your favorite music collection whilst enjoying your swim spa session.

    Class Leading Energy Efficiency

    All of our hot tubs and swim spas exceed the strict standards set by the CEC (Californian Energy Commission). Very few spas or indeed manufacturers are able to meet these standards and Master Spas pride themselves on their high quality Icynene insulation which translates to low running costs for the hot tub owner.
