What's the difference between express tunnel and full service economics?
Express tunnel: throughput-optimized, $12–18 ticket, 25–35% EBITDA, 50%+ revenue from unlimited members. Full service: labor-intensive, $25–45 ticket plus detail add-ons, 15–25% EBITDA, sub-10% membership penetration. The customer occasion is fundamentally different.

Why express tunnel won the rollup wave
The recent PE-driven consolidation focused almost exclusively on the express tunnel format because three economic properties scaled well across a chain:
- Recurring revenue — the unlimited membership program converts retail visits into MRR.
- Operating leverage — throughput-optimized labor model means incremental revenue carries minimal incremental cost.
- Site replicability — express tunnel footprints are standardizable across markets, supporting brand consistency and chain-level operations.
Where full service still wins
Full service operations remain strongly profitable in two contexts:
- High-income urban and suburban markets — customer base values hand-finished work and is less price-sensitive.
- Detail-add-on revenue stream — full-service formats often capture $80–150 per detail job on top of the wash ticket.
WashIndex tracks both formats at per-location resolution and surfaces aspect-level customer signals that differ meaningfully across the two formats.
