In the beginning, there was water.
And while itโs integral to our existence, weโve also come to realize it feels pretty good when warm. So good, in fact, that an entire profession emerged to provide everyone the benefits of hot water.
But we all know itโs more than that. To look at a hot tub now is to look at the sum of decades worth of invention and innovation, a history of problem solving and change.
To honor that entrepreneurial spirit, weโre taking a look back at the history of hot tubs. While itโs not comprehensive by any means, it hopefully serves as a friendly reminder that the industry, at such a young age, has accomplished so much.
And the exciting thing? Who knows where itโll go next.
1950s
โข In California vineyards, wine aficionados fill old wine vats, tanks and barrels with hot water to create the earliest hot tubs in American history. Those who were especially cunning took advantage of hot springs to enhance the experience.
1956
โข Two guys wonder if they can harness the power of water to help alleviate a family memberโs arthritis, and thatโs how the hydrotherapy pump was born. When it proves successful, they peddle the invention to hospitals and schools. By the way, the last name of those two gentlemen? Jacuzzi.
1960s
โข A new craze begins to take hold in residential design: the addition of a small body of hot water positioned next to a swimming pool. While these small bodies of water โ which had just one jet at the time โ delighted homeowners, they are seen strictly as accessories to a swimming pool. It will take time before we start to see standalone spas.
โข The Jacuzzi brothersโ hydrotherapy pump is featured as a common prize on game shows, thus bringing hydrotherapy awareness to a national audience.
โข At the same time the upper-class begin enjoying their gunite spas, the first wooden spas hit the California hills. Inspired by the traditional Japanese bathing tubs, they are typically made with materials from wineries. The wooden tubs appeal to a different audience than their gunite counterparts: the classic flower child of the โ60s.
1968
โข Roy Jacuzzi invents the first self-contained whirlpool bath. It has 50/50 air-to-water ratio jets and fully-integrated plumbing. In honor of the ancient society known for its bathhouses, Jacuzzi names his model the โRoman.โ
1970
โข After the success of his whirlpool bath, Roy Jacuzzi tries something new. He attaches a pump, motor, heaters and filtration system to a self-contained vessel and creates a prototype of the modern portable spa.
1970s
โข Around this time, a product and industry are born. Gunite spas in particular surge in popularity, but getting one is a hassle. The installation of a gunite spa requires an assembly line of different craftsmen handling different aspects of installation. Itโs common for the process to take two weeks or more.
โข Len Gordon, a Southern California contractor frustrated by the slow pace of spa production, seeks a faster way to meet demand. He manufactures the first fiberglass spa โ a mold coated with a non-stick separating agent, gel coat and then fiberglass for strength.
โข One inconvenience of early hot tubs: the electrical system. Switches and controls were located a short walk from the tub, a problem everyone tried to solve. Gordon creates a simple solution: an air switch.
โข Throughout the decade, wooden hot tubs dominate the spa market. They are low-cost and better known than fiberglass or acrylic โ yet the other segments were beginning to grow.
1973
โข Baja Products begins producing acrylic spas, which eventually become the champion of the industry.
1974
โข The largest and best known of the wooden tub makers, California Cooperage, begins operations.
1976
โข Baker Hydro creates the spa pack for HydroSpa. An integrated unit fitting under the skirt, it helps streamline the industryโs approach to plumbing.
1979
โข Fiberglass spas grow popular among customers, and everyone wants a piece of the pie. People begin setting up shops in garages to whip out copies of fiberglass spas โ oftentimes doing so by borrowing a hot tub, making a mold from it and using the mold to make new copies. The practice, called โsplashing,โ is deemed illegal.
โข As both reputable and sketchy spa manufacturers flourish, so, too, do complaints and skepticism toward the industry. Problems with poorly-made fiberglass spas plague the industry and force some manufacturers to close โ yet this opens the way for acrylic spas to join the party.
Early โ80s
โข As other manufacturers begin to see problems with surfacing โ blistering, splintering and more โ the Watkins brothers release a spa made of Rovel, a co-extruded material from Dow. An innovation from the boating industry, the material uses vinyl ester resin and acrylic instead of polyester resin, swiftly resolving surface problems.
โข The wooden spa begins its decline in favor of portable spas.
Mid-80s
โข Thanks to their convenience and ease of installation, portable spas begin surging in popularity and soon take the sales lead over ingrounds.
โข Basic controllers begin to appear on hot tub to help manage the various features. More and more, the portable spa begins to resemble what we see today.
1988
โข Spa sales reach a record 280,000.
The โ90s
โข Product turns a corner in reliability and quality. โIn the โ80s, consumers hoped the product would work, and in the โ90s, they expected the product would work,โ says Stan Chambers, AQUAโs West Coast account executive and 30-year industry veteran.
โข While the spa industry has largely been a product of California, it grows to a national level in the โ80s and goes international in the โ90s.
1995
โข Hot Spring debuts the synthetic cabinet. As the cost of redwood increases due to scarcity, this development helps cut manufacturer costs, but it also makes hot tub ownership easier and more convenient for customers.
Mid-90s
โข The industry continues to mature as smaller manufacturers disappear, leaving a core group to grow and dominate the market.
โข The retailer landscape changes, too. Smaller retailers looking to cash in on the hot tub craze fade away, leaving top professional outfits to prosper in local markets โ most of whom are still around today.
โข Cooperative advertising programs between dealers and manufacturers flourish.
โข Portable spas become much more sophisticated and elaborate. โI remember the โ90s as an era of what Iโll call โmore for more.โ There was a significant feature proliferation on products,โ says Mike Dunn, executive vice president at Wakins. More color options became available, more jets were added and horsepower increased. And as these features were added, hot tub prices increased accordingly, Dunn says.
โข New marketing themes emerge. โBack in the โ70s and โ80s, the hot tub was more about relaxation and fun and partying. As we went into the โ90s, there was a much greater focus on the hydrotherapy benefits of the product,โ says Jeff Kurth, president and CEO of Wexco, the parent company of Marquis Spas and Fox Pool Corporation. Manufacturers add more jets to target specific areas of the body and promote the improved health and wellness hot tubs could provide.
2000s
โข The green movement takes hold in the hot tub industry as manufacturers produce tubs that are more energy efficient.
โข Product complexity, especially at the high end of the market, increases dramatically. โThe rate of change increased significantly,โ Kurth says. โThe number of jets, the stereos, the iPod docks, Wi-Fi, flat-screen televisions, lighting systems โ the product is so much more complicated and sophisticated today.โ Dunn describes these add-ons as โexperiential, entertainmentโ features designed to meet the needs of a visual customer base. โWe would have used the phrase โthey buy with their eyesโ to describe them,โ he says.
2007
โข With very little warning, the American economy plunges into a deep and sustained recession. As home valuations dive, home equity financing of hot tubs dries up. Faced with great economic uncertainty, the core market for portable spas โ the American middle and upper middle class โ reigns in spending. Hot tub retailers and manufacturers are hit hard, while hot tub service remains relatively strong as many owners continue to maintain their units.
Present
โข As customer confidence begins to rebound, the sales message in the hot tub industry changes. โBefore, you had to talk โvalue, value, value.โ Now itโs, โYou can have what you want.โ The whole language of selling is much more sunny,โ says Alice Cunningham, co-owner of Olympic Hot Tub Company in Washington.
โข Hot tub controls can now be controlled through computers and smartphones.
โข Water care has advanced with new technologies like ozone and saltwater systems. โAll are aimed at trying to make the ownership experience for a consumer easier,โ Dunn says.
Whatโs next?
Kurth expects the industry will experience slow growth in the coming years, but he also sees one way to gain momentum.
โI think we as an industry have to do a lot more to make the hot tub relevant and top of mind,โ he says. โOver the last several years, as the industry has taken such a downturn, thereโs not a lot of advertising dollars being put into the national media.โ
Cunningham agrees, and cites the boating and RV industries as models to follow.
โThey came together and did these massive campaigns, not about a particular manufacturer, but about the joys of boating, the joys of RV-ing. Hot tubs and spas are in the same category, but the industry has never been able to mount a successful campaign to get into the consumersโ minds,โ Cunningham says.
Yet looking at todayโs hot tub, one thing is certain: โThe products have never been better. Theyโve never been more reliable or efficient,โ Cunningham says.
