📜 National Hot Tub Day History

Rome also had its own luxurious spas, with imperial leaders going even further than their predecessors to build magnificent baths. These spas were primarily established to provide medical assistance to weary soldiers who were injured or fell ill during battles.

The term “spa” originated from the Latin phrase “Sanus Per Aquam,” which means “health through water.” Roman spas encompassed various amenities such as sports stadiums, massage parlors, and restaurants.

In 1958, California became known as the birthplace of modern home spas. These early spas were often constructed using old redwood vats and discarded wine barrels. At that time, water purity and filtration systems were not prioritized, leading to the use of wood as a breeding ground for bacteria, mildew, algae, and slime. Fiberglass shell hot tubs were introduced in the late 1970s, replacing cast acrylic tubs. This innovation made it easier for owners to maintain water purity, and manufacturers began using plastic for pumps, filters, control systems, and jets due to its malleability and adaptability. However, it wasn’t until an Italian immigrant named Candido Jacuzzi came along that hot tub design significantly improved.

Candido Jacuzzi, an aircraft engineer, designed a whirlpool bath for his son Ken, who suffered from rheumatoid arthritis several decades ago. Roy Jacuzzi, a third-generation family member, then created and sold the first fully self-contained whirlpool spa. From that point on, the name Jacuzzi became synonymous with hot tubs.
