About Master Spas

Master Spas is based in Fort Wayne, Indiana. Operating out of a state-of-the-art, 45-acre campus, we are the largest swim spa manufacturer in the world, and largest hot tub manufacturer that builds 100% of our spas in the USA. Our management team has over 200 years of spa manufacturing success, and one of the strongest track records in the industry.

In a crowded hot tub market, most people notice that there's something different about Master Spas. It is hard to define but easy to recognize. It begins with the way we treat our customers—like family.

That means we always give you the best service, the best prices and, of course, the best products.

For over 25 years, Master Spas has proudly manufactured all of our hot tubs and swim spas in the United States. We believe it makes a noticeable difference in the overall quality of our products and gives customers yet another reason to choose Master Spas.
