What is a jacuzzi?

The trade name jacuzzi is a brand of hot tubs, bathing products, and pool equipment. It came into existence during the mid-20th century when the Jacuzzi brothers conceptualized an underwater pump to help arthritis patients.

Jacuzzi vs hot tub: The history

If you have read histories of ancient civilizations, you will know that hot tubs have been around for centuries. They have gradually evolved and improved to become the relaxation set-ups we see today. The first inventor got his idea for a hot tub from natural hot springs. He realized that the same principle could be replicated by using hot stones to heat water. This is how the first versions of hot tubs were created.

However, the concept of jacuzzis came to prominence at a later time. When the Jacuzzi brothers, in 1956, traveled from Italy to California, they invented a hydrotherapy jet pump. This invention then gave rise to the jacuzzis we know today — complete with massage jets and sleek, sophisticated designs.

Although you will find other brands that imitate similar features, jacuzzis still continue to top the list.
