When people talk about relaxing in a bubbling hot tub, they often call it a Jacuzzi, even if it is not made by the Jacuzzi brand. But where did the name come from, and why has it become so widely used?
The Origin of the Name
The term Jacuzzi comes from the Jacuzzi family, Italian immigrants who moved to California in the early 1900s. The family initially worked in aviation and agricultural pump manufacturing. In the 1950s, one of the brothers, Candido Jacuzzi, designed a portable hydrotherapy pump to help treat his son’s rheumatoid arthritis.
This pump could be placed into a bathtub to create a therapeutic whirlpool effect, circulating warm water and providing relief for sore muscles and joints. The invention became so popular that the family began producing built-in whirlpool baths, and the Jacuzzi brand was born.

From Brand Name to Common Term
Over time, the Jacuzzi brand became so well known that people started using the name to describe all hot tubs and whirlpools, regardless of who made them. This is an example of generic trademarking, where a brand name becomes the everyday term for a type of product, much like people say “Kleenex” for tissues or “Hoover” for vacuum cleaners.
The Modern Jacuzzi
Today, Jacuzzi is a global brand that manufactures hot tubs, swim spas, bathtubs, and saunas. The name is still strongly associated with relaxation, luxury, and hydrotherapy. While there are many brands of hot tubs, the Jacuzzi brand continues to be a market leader known for quality, innovation, and comfort.
Final Thoughts
It is called a Jacuzzi because it was invented and popularised by the Jacuzzi family. Their innovation in hydrotherapy transformed the bathing experience and created a product that became a household name around the world. Even though not every hot tub is a Jacuzzi, the name has become a universal symbol of warm, bubbling relaxation.
