Updated October 2026
Car washes have become one of the most talked-about small business investments of the past decade, driven by the rise of express tunnel washes and unlimited monthly memberships. They can be very profitable, but they’re also capital-intensive, and the industry has been reshaped by private equity and consolidation. This guide covers what a car wash franchise costs in 2026, how the economics work, and lower-cost ways into the car care business.
Types of car wash businesses
Table of Contents
| Type | How it works | Investment level |
|---|---|---|
| Express tunnel | Cars ride a conveyor through an automated tunnel in a few minutes; free vacuums; membership model | Highest |
| Flex-serve | Express tunnel plus optional interior cleaning and detailing | Highest |
| In-bay automatic | The car stays still while equipment moves around it; often at gas stations | Moderate |
| Self-serve bays | Customers wash their own cars with coin or card-operated equipment | Lower |
| Mobile detailing | Detailers travel to customers’ homes and workplaces | Lowest |
How much does a car wash franchise cost?
Tommy’s Express, the largest franchised express tunnel system in the US, is the clearest benchmark. According to its 2026 Franchise Disclosure Document (FDD), as summarized by 1851 Franchise:
| Tommy’s Express format | Estimated initial investment |
|---|---|
| World Model tunnel | About $3.48 million to $4.16 million |
| Flex Model tunnel | About $9.14 million to $11.85 million |
| Initial franchise fee | $50,000 |
Franzy’s summary of the 2026 FDD reports a combined investment range of about $4.98 million to $8.52 million and an average gross revenue of about $2.2 million per location from the FDD’s Item 19. These figures include land and ground-up construction, which is why they’re so high; the brand’s purpose-built tunnels, queuing lanes and vacuum stations require large sites.
Tommy’s Express has grown rapidly, passing 200 locations nationwide by 2025, with developers committing to multi-site territories.
Where the money goes
- Land, often the biggest variable.
- Site work: grading, paving, utilities, drainage and stacking lanes.
- Building construction.
- Tunnel equipment, conveyors, dryers and chemical systems.
- Water reclamation and treatment systems, increasingly required.
- Pay stations, license plate recognition and membership technology.
- Vacuum stations and canopies.
- Working capital and grand opening marketing.
How express tunnel economics work
Express washes make money through volume and memberships:
- Unlimited wash clubs let members pay a monthly fee to wash as often as they like. Memberships create predictable recurring revenue and are the core of most express wash business plans.
- Fast throughput lets a well-run tunnel wash many cars an hour with a small staff.
- Automation keeps labor costs relatively low compared with full-service washes.
The risks are high upfront costs, site selection, weather, and increasingly crowded markets as new tunnels open nearby.
Example: how memberships drive revenue
Imagine an express wash with 2,500 members paying an average of $30 a month. That’s $75,000 a month, or $900,000 a year, in recurring membership revenue before any single-wash sales. Retaining members matters as much as signing them up: losing even a small percentage each month means constantly replacing them through marketing and promotions. Operators track membership sign-ups, cancellations and wash frequency closely, and price memberships so that heavy users don’t erase the margin.
This example is illustrative; real membership numbers vary widely by market.
What running an express wash involves
- Equipment maintenance. Conveyors, brushes, dryers and chemical systems need daily checks and regular service; breakdowns on a busy Saturday are expensive.
- Staffing. Fewer staff than full-service washes, but you still need attendants, membership sales staff and a skilled maintenance technician.
- Chemical and water management to keep quality consistent and costs controlled.
- Customer experience: clean vacuums, fast lanes and quick resolution of damage claims build loyalty.
- Marketing focused on membership growth and retention, including local partnerships and promotions in slow seasons.
Environmental rules and water use
Car washes must manage wastewater, which contains soaps, oils and road grime. Most connect to sanitary sewers under local discharge permits, and many areas now require or encourage water reclamation systems that recycle part of the wash water. Rules vary by state and city, and drought-prone regions often have stricter requirements. Professional washes generally use far less water per car than washing at home, which can be a selling point. Check environmental and permitting requirements early, since they affect both cost and timing.
A consolidating, more competitive industry
The express wash boom attracted heavy private equity investment, and the market has consolidated quickly:
- Mister Car Wash, the largest chain by location count, operates hundreds of company-owned sites and doesn’t sell franchises.
- Driven Brands sold its car wash portfolio (formerly Take 5 Car Wash) to Whistle Express in 2025 in a deal worth about $385 million.
- ZIPS Car Wash, once a fast-growing consolidator, became a cautionary tale about over-expansion and went through bankruptcy restructuring.
For a new investor, this means more competition for the best sites and more pressure on membership pricing in crowded markets. Careful market analysis matters more than ever.
Lower-cost ways into car care
If a multi-million-dollar tunnel isn’t realistic, consider:
- Mobile detailing, which needs a vehicle, equipment, water and supplies, and can start for a small fraction of a tunnel’s cost. Ceramic coatings, paint correction and fleet contracts raise average tickets.
- Self-serve or in-bay automatic washes, often bought as existing businesses.
- Buying an existing wash with a track record, which reduces construction risk but requires careful due diligence on equipment age and real revenue.
- Detailing shops in a leased bay.
- Fleet washing for businesses with trucks and vans, often done on site after hours under a recurring contract.

Starting a mobile detailing business: a quick checklist
- Form your business and get insurance, including liability and coverage for customers’ vehicles. See our state LLC guides.
- Buy equipment: pressure washer, water tank, generator or power source, vacuums, extractors, polishers and quality products.
- Check local rules on water runoff; some cities restrict washing that drains into storm sewers, so use water-capture mats or waterless methods where required.
- Set packages and prices, from basic washes to full details and coatings. Use our pricing calculator.
- Build recurring revenue with maintenance plans and fleet or dealership contracts.
- Collect reviews and before-and-after photos to market your work.
How to evaluate a car wash investment
- Traffic counts and access: high daily traffic with easy entry and exit.
- Competition within a few miles, including planned openings that haven’t broken ground yet.
- Population and income in the trade area.
- Climate: regions with snow, road salt, pollen or dust support more frequent washing and stronger memberships year-round.
- Zoning and environmental permits, including water discharge rules.
- Membership pricing and penetration in comparable markets.
- Total investment and financing costs, especially with high land prices.
Financing a car wash
Car washes are often financed with SBA 504 or 7(a) loans, conventional commercial real estate loans, equipment financing and, for larger developers, sale-leaseback arrangements. Lenders look for real estate value, experience and conservative revenue projections. See SBA loans and how to finance business growth.
Example: starting with mobile detailing
An entrepreneur who can’t fund a tunnel starts a mobile detailing business with a van, pressure washer, water tank, vacuums and supplies. By offering monthly maintenance plans to busy professionals and contracts with local dealerships, they build recurring revenue and learn the market. After a few years, the business could expand into a fixed detailing shop or partner on a larger wash.
This example is illustrative.
Frequently asked questions
Can I buy a Mister Car Wash franchise? No. Mister Car Wash owns and operates all of its locations, so there’s no franchise to buy.
Why are express tunnels so expensive? Most require land, ground-up construction, specialized equipment and large sites with stacking lanes and vacuum areas.
Is it better to build new or buy an existing car wash? Building new lets you choose the location and equipment but carries construction and ramp-up risk. Buying an existing wash gives you revenue history from day one, but inspect the equipment, water systems and real financial records carefully, and check for new competitors planned nearby.
How long does it take to open an express tunnel? Often a year or more, including site selection, zoning approvals, environmental permits and construction.
Are car washes recession-resistant? Memberships and frequent washing in harsh climates provide steady revenue, but discretionary spending can fall in downturns and competition is rising.
