On May 4, 2026, Perspire Sauna Studio opened its hundredth location in Del Mar, California. Founder Lee Braun called it a proud moment for a brand that started with one Costa Mesa storefront in 2010. Four months later, three franchisees in New York signed on to build twelve SweatHouz studios across Lower Manhattan and Brooklyn, starting with a Tribeca flagship at 30 Warren St.
Anyone reading that expansion news and asking how much it costs to open a cold plunge and sauna recovery studio gets a number back fast: fifty thousand dollars. That figure tops nearly every cost guide on the first page of Google.
It’s off by an order of magnitude for the kind of studio those franchisees are actually building. Perspire’s own franchise disclosure document puts a single studio at $565,538 to $989,638. SweatHouz lists $631,798 to $1,314,102 on its franchise page. The $50,000 number describes a different business that happens to share the same search query.
Opening a cold plunge and sauna recovery studio costs anywhere from about $18,000 for a towed mobile unit to $1,314,102 for a franchised build-out, and the spread exists because three unrelated businesses are hiding behind one keyword. Which number applies to you is settled before you price a single sauna, by whether you plan to sell sessions, memberships, or bookings.

Quick answers
How much does it cost to open a cold plunge and sauna recovery studio?
Between $18,000 and $1,314,102, depending on format. A towed mobile sauna and plunge setup starts near $18,000. An independent storefront studio runs $50,000 to $350,000. A franchised studio from SweatHouz or Perspire costs $565,538 to $1,314,102 per location, per their franchise disclosure documents.
Is a cold plunge studio profitable?
Profitable, yes, but slowly. Perspire’s corporate studios reported an 18.4% net margin on $615,358 in average revenue, about $112,940 a year. Against a build cost starting at $565,538, that’s five years to repay the construction alone, and the bottom quartile of franchised studios takes closer to nine.
How much do sauna franchises cost to open?
SweatHouz quotes $631,798 to $1,314,102 with a $45,000 franchise fee and 6% to 8% royalties plus a 3% brand fee. Perspire’s 2025 filing shows $565,538 to $989,638 with a $50,000 fee and 7% royalty. Restore Hyper Wellness runs $762,448 to $1,236,588.
How much does it cost to open a cold plunge and sauna recovery studio?
The honest answer is a range of $18,000 to $1,314,102, and the reason the published estimates disagree so wildly is that they’re pricing different businesses. A single 8-by-10 private suite with one sauna and one plunge is a piece of equipment in a leased room. A SweatHouz studio is a multi-room build-out with mechanical work, a membership funnel, and a franchise agreement attached.
The widely circulated $50,000 to $500,000 figure, published by Contrast Therapy Finder, isn’t wrong for independent operators. It breaks down cleanly: a commercial infrared sauna at $5,400 to $20,000, a commercial cold plunge at $4,990 to $24,000, leasehold improvements at $15,000 to $150,000, electrical at $500 to $3,000, plumbing at $300 to $2,000, and three months of reserves at $25,000 to $75,000.
What that range omits is that almost nobody building a studio in 2026 is building at the bottom of it. The growth in the category is coming from franchise groups signing multi-unit deals, and their filings are public.
Demand is real, which is why the capital is showing up. The Global Wellness Institute put the wellness economy at $6.8 trillion in 2024 in its Global Wellness Economy Monitor released November 19, 2025, with the spa sector growing 14.6% year over year and thermal and mineral springs up 11.1%. That’s the tailwind every pitch deck in this category cites.
One sentence worth holding onto: the studio format you pick determines your cost, and the cost determines how many paying bodies you need through the door every week for the rest of your lease.
The three studio formats and what each one really costs
There are four viable formats, and they sort by capital rather than by concept. Mobile units test demand. Single-suite studios sell sessions. Open-community studios sell memberships. Franchises sell a system.
| Format | Startup cost | Space needed | How it earns | Best for |
|---|---|---|---|---|
| Mobile trailer | About $18,000 for the unit | None, plus storage | Around $225 per booking, 14 bookings a month | Proving local demand before you sign anything |
| Single private suite | From $12,000 in equipment, $50,000 all in | 8 by 10 feet minimum, 300 sq ft studio | $60 to $150 an hour, or $25 to $75 drop-ins | Adding recovery to a gym, spa, or clinic you already run |
| Open-community studio | $100,000 to $350,000 | Up to 3,000 sq ft | Memberships near $199 a month, one staffer on shift | Markets with an existing social-bathing crowd |
| Franchise | $565,538 to $1,314,102 | Leased multi-room build-out | $615,358 to $1,031,755 average annual gross | Buyers with $550,000 liquid who want a playbook |
The mobile numbers come from a public planning calculator rather than a filing, so treat them as a starting sketch. At $225 a rental, 14 rentals a month, and roughly $740 in monthly running costs, a trailer pays for itself in seven or eight months. That’s the cheapest way to learn whether your town wants this before you commit to five years of rent, and it’s the same logic behind starting a mobile bar business instead of leasing a venue.
The open-community model deserves more attention than it gets. LIT Method’s operator guide prices an equipment package for up to 600 members at $100,000 to $250,000 and notes that one staff member can run the whole floor. At a $199 community rate, 400 members produce $79,600 a month. The catch is the layout ratio: roughly one cold plunge per five sauna users, which means plunge capacity, not sauna capacity, is what caps your peak-hour throughput.
Othership is the clearest proof that the social version of this business attracts real money. The Toronto company raised $8.5 million through a SAFE from 57 investors, has taken in more than $10 million in total venture funding, and counts the founders of SoulCycle and Daybreaker among its backers. Its saunas hold up to 70 people per session at 175 to 185 degrees, with plunges at 32 to 40 degrees. That’s a communal experience business, closer to the loneliness economy than to a spa.
How much do sauna franchises cost to open?
Between $565,538 and $1,314,102 for a single location, with franchise fees of $44,500 to $50,000 and ongoing fees of 9% to 11% of gross revenue. These are not estimates. They come from Item 7 of each brand’s franchise disclosure document, the filing the Federal Trade Commission requires before anyone can sell you a franchise.
SweatHouz states its range as $631,798 to $1,314,102 on its own franchise page, with a $45,000 franchise fee, royalties of 6% to 8%, a 3% brand fee, and a minimum liquidity requirement above $550,000. The company lists 59 locations open or in construction, 38 franchise groups, and 478 available territories. Its Manhattan and Brooklyn group was quoted a slightly older range of $569,757 to $1,193,974, which tells you these numbers move between FDD editions.
Perspire’s 2025 filing breaks the build down further: a $50,000 franchise fee, $67,000 to $87,000 in equipment, $341,000 to $585,000 in leasehold improvements, and $25,000 to $60,000 in operating capital for the first three months. Royalty is the greater of 7% of gross revenue or $600 a month, plus a 2% brand fund. Restore Hyper Wellness sits highest at $762,448 to $1,236,588 with a $44,500 fee, 7% royalty, 2% ad fund, and a mandatory $600 monthly technology fee.
Notice where the money goes. In Perspire’s own breakdown, leasehold improvements are six to eight times the equipment cost. The saunas and plunges are the cheap part. You’re paying for drainage, dedicated electrical service, ventilation, waterproofing, and the contractor who knows how to put a commercial plunge on the second floor of a retail building.
Add the recurring fees and the drag is permanent. On a studio grossing $817,000, which is the per-unit annual revenue reported for SweatHouz, an 11% combined royalty and brand fee takes about $89,870 off the top every year before rent, payroll, or utilities. If you’re weighing a franchise against building your own, the factors worth evaluating before investing in a franchise matter more here than in most categories, precisely because the build cost is so high. Operators shopping the lower end of the market should compare against low-cost franchises before committing this much capital to one address.
Is a cold plunge studio profitable?
Yes, at a roughly 18% net margin, and that margin is the most useful number in this entire category because one franchisor published it. Perspire’s 2025 filing discloses that its corporate and affiliate studios averaged $615,358 in revenue with net profit of $112,940.33, an 18.4% margin. Almost no franchisor in wellness discloses net profit at all.
Now run that margin against the build cost, which is the calculation the cost guides skip. At 18.4% on $615,358, a studio clears about $112,940 a year. Against Perspire’s own minimum build of $565,538, that’s five years to repay construction, before debt service and before the owner takes a salary.
The quartile data is where it gets uncomfortable. Perspire’s Item 19 disclosure, covering 50 studios open for the full 2024 year, reports franchised averages of $719,928 for the top quartile, $595,633 for the second, $488,351 for the third, and $340,875 for the bottom.
Read that bottom number again. A studio in the weakest quarter of the system grossed $340,875 for the year, which is $224,663 less than the cheapest version of the same studio costs to build. Applying the disclosed 18.4% margin, that studio nets roughly $62,700 a year, putting repayment of the minimum build at about nine years.
The published averages also flatter the category in a way worth naming. Restore Hyper Wellness reports average gross sales of $1,031,755 across 207 franchised studios open twelve months or more, with 254 active memberships per location. That average excludes 13 permanently closed studios, and the same system saw 49 franchised outlets cease operations between 2023 and 2025 against a peak of 216 outlets in 2023, a 7.1% closure rate. Averages in franchising are survivor figures.
Per-unit economics are kinder. Commercial chiller suppliers put a single plunge’s payback at 6 to 9 months in a high-traffic facility and 18 to 24 months in a low-traffic one, at $10 to $25 a session. That’s why adding a plunge to an existing gym is a sound bet and building a studio around one is a real estate decision wearing wellness clothing. The same distinction sank a lot of hype-driven consumer plays, including Prime Hydration: demand for the category is not demand for your location.
Do you need a license to open a recovery studio?
Yes, in most jurisdictions, and it’s usually a public bathing permit rather than a spa licence. A commercial sauna, steam room, or cold plunge is typically regulated as a bathing establishment, which means a health department permit, engineer-stamped plans, and periodic inspection.
New York City is the cleanest example because the fees are published. The Bathing Establishment without Pool permit, which covers saunas, steam rooms, and spray grounds, costs $1,120 to apply for and $260 a year to renew. It’s issued by the Department of Health and Mental Hygiene’s Office of Public Health Engineering under Article 165 of the NYC Health Code and the New York State Sanitary Code. Getting it requires a Certificate of Occupancy, a floor layout plan prepared by a New York State licensed engineer or architect, PHE Forms 100 and 88, proof of workers’ compensation and disability insurance, and no outstanding Health Code violation fines.
The permit fee is trivial. The engineer-stamped floor plan and the construction inspection phase are not, because they’re what turn a six-week fit-out into a five-month one while rent accrues. New Jersey issued separate cold plunge guidance in December 2025 under its public recreational bathing rules, which is a signal that state regulators are writing plunge-specific requirements rather than treating the tubs as furniture.
Check three things with your local health department before you sign a lease: whether plunges are classified as public bathing, what water disinfection and testing records you’ll have to keep, and whether an attendant must be on site during operating hours. Staffing rules change your payroll model more than any equipment choice will.
Four line items that wreck the budget
Four costs consistently run over: mechanical work, utilities, pre-opening marketing, and the gap between signing the lease and taking the first payment.
Mechanical and leasehold work is the big one. Perspire’s filing puts leasehold improvements at $341,000 to $585,000 and SweatHouz’s at $365,600 to $719,000. The independent range from Contrast Therapy Finder tops out at $150,000. That gap is the difference between putting equipment in a room that was already plumbed and building a wet facility from a shell.
Utilities are the cost people forget. Running saunas at 175 to 185 degrees and chillers at 32 to 40 degrees, all day, in the same building, puts monthly utilities at $800 to $3,500 for an independent studio. That’s before you discover your suite’s electrical panel needs a service upgrade.
Pre-opening marketing is budgeted at $10,000 to $40,000 in SweatHouz’s filing, and it’s real spend, not padding. A membership business with no members on opening day has no revenue. LIT Method’s three-tier pricing ladder exists for exactly this reason: roughly $99 a month for founding presale members, about $149 for the opening rate, then $199 as the standard. You’re discounting to fill the room before you’ve built it.
Then there’s the dead period. SweatHouz budgets $20,000 to $60,000 for three months of rent and deposits and another $20,000 to $40,000 in additional funds. Contrast Therapy Finder recommends $25,000 to $75,000 in reserves. Whichever number you use, hold it separately from the build budget. Operators who fold the reserve into construction run out of cash in month four, which is the single most common way these studios die.
What to settle before you sign a lease
Settle four questions in this order: format, throughput, permit class, and reserve. Everything else follows.
Start with format, because it sets your capital requirement, and the capital requirement is what you actually have to finance. If you can’t put $550,000 of liquid capital behind a franchise, that path is closed regardless of how good the brand looks, and SweatHouz says so plainly in its own disclosures.
Then calculate throughput backward from your build cost. Take your total investment, divide by the 18.4% margin Perspire disclosed, and you get the annual revenue you need to repay construction in a given number of years. On a $600,000 build repaid over five years, that’s roughly $652,000 of annual revenue, or 273 members at $199 a month. Ask yourself whether your trade area has 273 people who will pay that every month for five years. That question, answered honestly, kills most of these projects, and it should.
Confirm the permit class with your health department in writing before the lease is signed, not after. A plunge classified as public bathing changes your plumbing spec, your records obligations, and possibly your staffing floor.
Last, fund the reserve as a separate line. Three months minimum, six if your market has a seasonal dip.
If the math doesn’t work, the honest move is the trailer. An $18,000 mobile unit generating $2,400 a month in profit tells you in one summer what a five-year lease would take three years and $600,000 to teach you. Test before you build, the same way you would with any other facility-based business. Given how much capital a studio locks into a single address, 2026’s case for staying lean applies here with unusual force, and the underlying shift in how people approach wellness is what makes the category worth testing in the first place.
Perspire has delivered more than 5 million sessions since 2010 and awarded over 280 franchise licenses across 27 states. The demand is not in question. Whether it exists within a ten-minute drive of the specific storefront you’re about to lease is a different question entirely, and it’s the only one that decides whether a cold plunge and sauna recovery studio is worth what it costs.
