Evaluating Swim Spa Shell Construction

What I wish I knew before buying a swim spa.
What happens here
Oliver details the structural integrity of the swim spa shell, explaining that many manufacturers use a 'hung shell' design, where the shell is supported from its upper neck with metal pieces or 2x4s. This method can lead to flexing, hairline fractures, and warping over time due to the immense weight of the water (15,000 to 25,000 pounds). In contrast, Master Spas utilizes a 'self-supporting shell,' where the entire footwell area is structurally sound from the ground up, preventing flexing and ensuring long-term durability. Oliver demonstrates this by standing and jumping inside the empty spa, showing its rigidity.
Goal: Understand the difference between 'hung' and 'self-supporting' swim spa shells for durability.
