The enjoyment of warm therapeutic waters, ultimately leading to the creation of modern day hot tubs, has an interesting history!

• Early hot tubs were held in calderas or volcanic craters and used as baths carved of solid granite.
• 1700s – Native Americans embraced the healing waters in various parts of the United States.
• 1800s to early 1900s – Resort spas begin popping up in Europe and the US.
• mid 1900s – Post WWII, wooden spas became popular, some even made of wine barrels!
• 1960s – Concrete spas with jets enter the scene at a high cost.
• 1960s – 1970s – Acrylic spas gain popularity.
• 1979 – Sundance Spas opens manufacturing in Costa Mesa, CA and creates industry firsts such as: recessed jets, Whirlpool Therapy Jets, Rigid Bond shell construction (still used today), and many specialized hydrotherapy jets.
