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.
SMARTER HEATING
Heat Pump Technology
An air source heat pump can help reduce your hot tub’s heating costs by up to 70% compared with a conventional electric heater. All new models come heat pump ready, giving you the option to add this energy saving upgrade.
How does it work?
A heat pump transfers warmth from the outside air into your water, helping reduce heating costs. Savings depend on the heat pump, outdoor temperature, electricity tariff, insulation and usage.
Our team can advise on compatibility, installation and whether a heat pump is right for you.
