Description
The Strong Spas G2B is one of the most reliable, low-maintenance and durable hot tubs on the market — designed specifically for holiday lets, rentals, and busy family homes. Engineered in the USA by Strong Spas, the G2B delivers exceptional strength, simple operation and outstanding performance, making it a top choice for anyone who needs a spa that can handle heavy, everyday use.
Built with Strong Spas’ signature DURA-SHIELD hardcover, the G2B features an integrated, insulated cover that is lockable, weatherproof and virtually maintenance-free. This eliminates the need for lifting covers, reduces wear and tear, and significantly lowers running costs — ideal for rental properties and commercial environments.
Inside, the G2B offers comfortable seating, efficient hydrotherapy jets, LED lighting and a user-friendly control system, making it perfect for guests and owners alike. Its durable, rotationally moulded construction ensures longevity, while the simple water management system keeps maintenance quick and straightforward.
If you’re looking for a robust, energy-efficient and hassle-free hot tub designed to withstand constant use, the Strong Spas G2B is the perfect solution for holiday homes, Airbnbs, rentals or families wanting reliability above all else.

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.

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.
