Car Wash Insurance Cost: Ranges + Calculator
A car wash holds customers' vehicles in its care all day — in the tunnel, on the conveyor, in the detail bay — which makes garagekeepers legal liability the defining line: antenna snapped, mirror caught, paint scratched, all yours. Around it sit general liability for the wet-surface slip exposure, equipment breakdown on the wash line that IS the business, and workers' compensation for the crew.
As an industry-typical estimate, a small wash commonly runs roughly $3,000–$9,000+/year across GL, garagekeepers and equipment coverage. No insurance bureau publishes car-wash premiums, so every dollar here is an estimate; each fact is sourced to a named authority (IRMI, III, NCCI, OSHA).
