Jacuzzi is an American private company that manufactures and markets hot tubs, pools, and other bath products.^[1] It is best known for the Jacuzzi hydrotherapy products.^[2][1] The company is headquartered in Irvine, California. It is the largest hot tub manufacturer in Europe^[1] with eight factories, the largest being in Italy.^[3]

The company was founded in 1915 by seven Italian immigrant brothers from the Jacuzzi family in Berkeley, California.^[4] It developed a variety of products including pumps for agricultural use. In 1948, Jacuzzi created water pumps to treat a family member's rheumatoid arthritis.^[5] The water pumps were a niche medical product until they were integrated into a recreational hot tub in 1968. As the popularity of hot tubs grew, Jacuzzi created more models that were more advanced. Jacuzzi was family-run until 1979, after which it then changed hands several times, before being bought by its current owner Investindustrial in 2019.

The Associated Press Stylebook lists Jacuzzi as a trademark brand for products like hot tubs, whirlpool spas, and whirlpool baths^[6] and it may not be legal to use the name in a commercial context without permission.

Jacuzzi was founded by seven siblings in the Jacuzzi family: Giocondo, Frank, Rachele, Candido, Joseph, Gelindo and Valeriano, who were from Casarsa della Delizia in northern Italy.^[7] Their original last name was Iacuzzi, but when the first two brothers emigrated from Italy to the US in 1907, immigration staff misspelled their name as "Jacuzzi".^[8] All seven siblings had emigrated by 1910.^[8] More family members emigrated to the U.S. when the brothers won a contract to provide propellers to the U.S. for World War I planes.^[9]

Jacuzzi began as a machining company.^[10] The brothers worked on a citrus farm owned by an early aviation inventor.^[8] They offered to help develop aviation products, creating an early wood propeller that was curved instead of flat^[8] and was used in World War I.^[11] One of the first propellers they made is now either in storage at or on loan from the Smithsonian Institution.^[8] They also developed one of the first fully-enclosed cabins for airplanes, called the Jacuzzi J-7, which was used to transport mail.^[8]

In 1921, a mail plane crashed, killing all of the passengers on board, including Giocondo Jacuzzi.^[8] The siblings subsequently abandoned the aviation industry and experimented with several other products, the first successful one being a water pump created by Rachele Jacuzzi in 1926.^[12] The product line expanded into a variety of pumps.^[13]

In 1948, Candido Jacuzzi developed an improved full body hydrotherapy pump, the J-300, to treat his son's (Ken Jacuzzi) rheumatoid arthritis between hospital visits, after noting his positive response the smaller Hubbard tank at the Herrick hospital in Berkeley.^[14] He patented the pump in 1952^[10] and began marketing it between 1955 and 1956 as a therapeutic aid.^[14] The pump was a portable device that could turn any regular bathtub into a spa.^[15]

From 1968, a whirlpool bath was produced, which included jets that mixed air and water. This product (called the Roman Bath) was developed by Roy Jacuzzi, a 3rd-generation member of the family.^[16] This is considered the first whirlpool tub designed for relaxation, rather than for medical use.^[17] Jacuzzi used celebrity Jayne Mansfield and others to market the tubs, which initially gained popularity among Hollywood movie stars.^[14] In the 1970s, Jacuzzi products were featured on Queen for a Day and other TV shows and grew in popularity in California.^[9] The company started developing larger models that could fit more than one person. They also added filters and heaters, so the tub didn't need to be drained with each use.^[18] From 1970, family-sized spas were producted.^[19]

By 1989, Jacuzzi had 2,200 employees.^[13] Initially, Jacuzzi primarily sold through contractors and builders, but in 1993 it started selling through retailers.^[20] In the 1990s Jacuzzi entered markets outside the US, especially in Italy and Spain. By the end of the 1990s, half of its sales were outside the US.^[18]

Jacuzzi was influential in the trend towards larger and more luxurious bathrooms.^[12]

By 1979,^[9] there were 257 Jacuzzi family members involved in the Jacuzzi brand and there was a growing number of disputes among them.^[20] Then the business was acquired by Kidde for $70 million.^[9] Most of the Jacuzzi family members left the company, except Roy Jacuzzi, who stayed on as the head of the hot tub and bath division.^[21] In 1987, Kidde was acquired by Hanson PLC.^[22] In 1995 Hanson spun off Jacuzzi and other brands into a public company called U.S. Industries.^[18] USI renamed itself Jacuzzi Brands in 2003.^[23] This was in turn bought out by Apollo Management,^[2] and then by Investindustrial in 2019.^[24]

Acquisitions since the 1990s have included Haugh Products^[20] (above-ground pools), Sundance Spas,^[20] Gatsby Spas,^[20] Zurn Industries (toilets, sinks), Hydropool (hot tubs), Liners Direct (bath products), BathWraps (shower and bathtub renovation).^[25] In the 1990s, Jacuzzi had taken on too much debt and sold more than $600 million worth of businesses.^[18] The business segment producing industrial, irrigation, well water, submersible, and centrifugal systems was sold to Franklin Electric in 2004. The plumbing division, Zurn Industries, was sold in 2007 for $950 million.^[26] Current brands include ThermoSpas, Sundance Spas, and Dimension One.
