Car Wash Industry Growth: What the Numbers Say for 2025–2026
The car wash industry has had a strong run, and the data for 2025 and into 2026 reflects a market that continues to expand — even as it evolves in ways that require operators to pay closer attention to how they run their businesses.
Market Size and Scope
Grand View Research estimated the global car wash service market at $36.29 billion in 2025, with growth expected to continue through the decade. North America remains the dominant region, holding approximately 40.76% of global market share, according to Mordor Intelligence.
In the United States, the International Carwash Association estimates approximately 62,750 car wash and auto detailing outlets operating nationally. New site development has continued at a pace of 600 to 700 new locations per year.
Express tunnel washes have become the industry's growth engine. Research from Persistence Market Research puts the express tunnel segment at roughly 51% of U.S. industry revenue, growing at a 6.1% compound annual growth rate.
Membership Revenue Is Now the Story
Perhaps the most significant structural shift over the past several years has been the rise of membership programs. Rinsed's Q4 2025 quarterly report, tracking data from more than 3,000 locations, found that membership revenue grew 11.3% year-over-year — while retail revenue declined 8.4% over the same period.
That divergence matters. In Q4 2025, Mister Car Wash, the largest U.S. chain with approximately 550 locations, reported that subscription revenue represented 79% of total wash sales — up from 72% in Q2 2024.
At the industry level, mature tunnel washes typically report memberships accounting for 40 to 60% of revenue, with top performers reaching 70 to 75%. The direction is clear: membership-based revenue is becoming the foundation, and retail is becoming secondary.
Member Satisfaction Is High — But So Is Churn
The ICA CAR WASH Pulse report for Q4 2024 found member satisfaction at its highest recorded level — 83% of members described themselves as "very satisfied," and 93% said they intended to renew their membership. The Q1 2026 ICA Pulse found that nearly 79% of customers said they would accept a price increase from their car wash.
Those are strong numbers. But they exist alongside a monthly churn rate of 7.6%, per the Rinsed Q4 2025 report — a figure that remains well above the cross-industry subscription average of approximately 3.4%, as measured by Recurly Research across 2,200+ subscription businesses.
The implication: the industry has enthusiastic members, but turnover remains high. The gap between satisfaction and retention suggests that a portion of churn is driven by operational factors — equipment performance, wash quality consistency, service gaps — rather than dissatisfaction with the concept of membership itself.
Market Saturation Is Becoming a Concern
The ICA's Q1 2026 Pulse found that market saturation and site density is now the top strategic concern among car wash operators — a shift from prior years, when customer acquisition and membership growth led the list.
As more sites are built, especially in high-growth markets, competition for the same pool of members intensifies. This makes retention increasingly important: when acquiring new members is harder because the market is more crowded, holding the ones you have becomes a larger proportion of the growth equation.
What High-Performing Washes Do Differently
Rinsed data from Q4 2025 reveals a clear performance gap based on membership scale. Sites with more than 4,000 members converted retail customers to memberships at a rate of 15.6%. Sites with 2,000 to 4,000 members converted at 10.3%. Sites with fewer than 2,000 members converted at under 3%.
That gap isn't just about marketing. Larger, more established membership programs tend to have the operational infrastructure — inspection processes, maintenance schedules, consistent onboarding experiences — that reinforce the value of membership in the first few visits.
The ICA's ICA's Bob Klein, summarizing the Q4 2024 Pulse data, noted that the highest-performing operators delivered "consistent quality and a strong experience" — and that members who had that experience were far more likely to stay and to upgrade their plans.
The Takeaway for Operators
The industry is healthy and growing. But the growth is concentrated among washes that have figured out how to convert and retain members at scale. For the majority of operators — particularly those under 4,000 members — the opportunity is significant, and the lever is operations: delivering a consistent, high-quality experience across every shift so members stay longer and tell their friends.
