Hot tubs are quickly becoming a hot commodity worldwide, but the market for them is particularly strong in the United States, where general availability and overall income increases have made hot tubs affordable to a much wider range of buyers. The hot tub manufacturing industry is a strong subset of the American market, with many top manufacturers making high-quality tubs domestically. In this guide, you will find key data regarding the domestic production scale, brand output, and industry capacity of hot tubs in the United States.

The State of U.S. Hot Tub Manufacturing in 2026

In 2026, the U.S. hot tub manufacturing industry is projected to be on the cusp of escalating revenue increases. After a large surge in demand for hot tubs during the COVID-19 pandemic, which pushed revenue up to approximately $1.2 billion in 2022, the industry currently sits at $1.1 billion in revenue for 2026 [1][2]. When including imports in the equation, this number rises to about $2.8 billion in revenue [1][2].

Industry trade data suggests that Americans own anywhere between 5.8 and 7.3 million hot tubs [3]. While data suggests that sales and new construction trends are slowing slightly, the hot tub market has maintained revenue through an increase in service and remodeling requests, and trends indicate that a main driver behind new purchases is the health and wellness vertical, particularly in regards to the pairing of cold plunge spas with hot tubs and other spa products [2][4][5].

Industry cost pressures largely have to do with hot tub regulations and import tariffs, including on components such as pumps, compressors, valves, and fittings, which utilize highly-tariffed steel and aluminum [6]. Environmentally-friendly legislations such as California’s gas-heater ban and variable-speed pump requirements also impact revenue [7].

Domestic Production Scale

Total U.S. Hot Tub Units Produced Annually

Domestic production of hot tubs accounts for a sizable portion of annual market composition. Recent estimates are difficult to track, but the most recent available pre-pandemic study, done in 2019, found that there were 225,000 units sold in 2018 [8]. Post-pandemic, hot tub sales experienced a brief decline, but are now rebounding, and current estimates suggest that anywhere from 210,000-250,000 units are manufactured annually [9][10].

Share of Imports vs. Domestic Production

Publicly-available data suggests that, as of 2025, the U.S. market share estimate for hot tubs was nearly 60% domestic manufacturing and approximately 40% imports, which can be broken down into about 31% fully-imported finished goods and about 9% imported components that are subsequently used in U.S.-made units [10][11].

The market share of imported goods or components is heavily-impacted by import tariffs, while the domestic market has been slightly negatively affected by lower prices, supply chain disruptions, and increased overseas production [10][11].

Among the many U.S.-based hot tub manufacturers, LPI, Inc. is the largest hot tub manufacturer in the country. Employee-owned and founder-led, LPI manufactures over 20,000 units a year in the U.S. across a variety of high-quality brands, including Catalina Spas, Dr. Wellness, Whisper Spas, Plug & Power, Tuff Spas, Hudson Bay. Through its subsidiary dealers, Aqua Living (soon to be rebranded Whisper Outdoor in 2026) and HotTub.com, LPI delivers factory-direct pricing on all of its models and offers exceptional brand reliability and full-coverage warranties, as well as financing for low and no-credit buyers.

Industry Capacity and Growth Trends

As the national hot tub market in the U.S. expands and develops, various factors influence its capacity and growth trends. Some of the major factors affecting how the market is growing include:

 

  • Factory Footprint: Manufacturing space and factory footprint influence the overall capacity of the industry. As manufacturers expand their factory space, they enhance capacity and can effectively manufacture more units, driving up supply to meet increasing demand [12].


  • Employment and ESOPs: Employee Stock Ownership Plans (ESOPs) are slowly becoming part of the hot tub manufacturing industry, spearheaded by employee-owned manufacturers such as LPI. This trend reflects a growing interest in adapting the hot tub market away from private equity and Fortune 500 manufacturers towards employee-led ventures. 


  • Year-Over-Year Growth: Signs of recovery from the brief decline in hot tub sales across 2020-2023 indicate that the industry is poised to expand year-over-year, with expected revenue increases of about 4.9% estimated over the next 12 months [13].

Patented Innovations from US Manufacturers

Manufacturer Number of Patents
LPI, Inc. 7
Bullfrog Spas 11
Master Spas ~20–50

U.S.-based hot tub manufacturers continually innovate in the market by applying for patents pertaining to their individual technologies and features. Some examples of high-quality patented innovations by LPI, the leading U.S. hot tub manufacturer, include:

 

  • Heat-Flow Manifold: Allows for the natural heating of water through generated friction, rather than the use of a heater.


  • Tuff Top: Insulated, hard-shell cover that is crack and tear-resistant, with a lifetime guaranteed warranty.


  • AnyTemp Chiller: Used for setting chilled water temperatures for the purposes of cold-water hydrotherapy and exercises.


  • Aqua Rejuvenation: LED Light Therapy system that reduces inflammation, stimulates collagen production,  and promotes cellular repair.

Why Domestic Manufacturing Matters

The domestic manufacturing of hot tubs has a huge impact on the U.S. market, affording buyers a greater degree of freedom, transparency, and availability when it comes to products and prices. Crucially, U.S.-based manufacturing acts as an employment generator for local workers, expanding economic growth beyond the market [14].

Manufacturing in the U.S. also affords customers greater assurance of quality and accountability, as local dealer networks can offer extensive post-sale support and can be directly accountable to buyers in regards to issues [10]. Local manufacturing also allows for greater supply chain resilience due to a lack of tariffs and potential shipping delays due to international disputes [10]. Finally, U.S.-based manufacturing allows customers to purchase hot tubs at better price points, avoiding costly fees and hidden markups [7].
