HOTWORX

The 2026 FDD estimates the total initial investment at $288,890–$830,380, including the $19,950 initial franchise fee. The substantial range reflects differences in studio development costs, equipment, construction and other startup expenses.

HOTWORX’s current franchise website describes a typical single-unit studio as a 1,500–2,200-square-foot location with six to 10 infrared saunas. The exact number of saunas and the size of the facility influence the investment required.

The company does not currently publish an official average investment figure. For a franchise profile, therefore, the FDD investment range is more appropriate than calculating a midpoint and calling it an average.

HOTWORX combines infrared heat, infrared energy and exercise through its patented 3D Training concept. Members can choose 30-minute isometric workouts such as Hot Yoga, Hot Pilates and Hot Barre, or 15-minute HIIT sessions.

The studios also include an FX Zone for functional training with equipment such as weights, resistance bands and ropes. Virtual instructors deliver the sauna workouts, allowing the studios to operate with relatively limited staffing compared with conventional gyms.

The membership model is designed around recurring revenue. Members receive 24-hour access, while the studio can accommodate multiple sessions throughout the day. HOTWORX says a 10-sauna studio can provide up to 576 group sessions and 1,728 individual sessions per day.

The latest FDD-based figures provide a more useful benchmark than the promotional figures sometimes cited online. For 700 franchised studios that were open during all 12 months of 2025, average gross revenue was $379,298, while median gross revenue was $354,221.

The same reporting group had a revenue range extending from approximately $163,899 to $901,879. This illustrates the variation between individual studios and means the average should not be treated as an expected result for a new location.

The FDD also reports EBITDA information, but revenue and EBITDA should not be confused with the owner’s personal income. The financial-performance disclosure does not include every cost a franchisee may incur, so candidates need to model rent, payroll, debt service, taxes and other operating expenses separately.

Unlike many restaurant and fitness franchises that calculate royalties as a percentage of sales, HOTWORX’s 2026 FDD lists a flat $695 monthly royalty per studio. This means the royalty does not increase directly with gross revenue.

The 2026 FDD-based data also identifies a $1,800 monthly technology fee. Because recurring fees can change between FDD editions, prospective franchisees should verify the complete current Item 6 fee schedule before signing.

The current HOTWORX franchise website confirms the $19,950 single-unit franchise fee. For multi-unit/Area Developer agreements, the published structure is $39,950 for three licenses, followed by $15,000 for one additional license and $10,000 for each additional license of two or more.

HOTWORX passed 900 open studios worldwide in September 2026, according to the company and the International Franchise Association. The network has more than 400,000 members across the United States, Canada, Ireland and Dubai, with further international markets in development.

For a U.S. franchise database, however, I would use the FDD’s outlet count rather than the current worldwide headline figure. The 2026 filing shows 797 franchised outlets and 15 company-owned/managed studios at the end of 2025.
