Is a 15,000 sq ft laundromat realistic to build?
Yes — mega laundromats exist across the U.S. and are increasingly common in high-growth Sun Belt markets. Success requires thorough feasibility analysis: strong demographics (25-40% renters), institutional demand (hotels, hospitals, universities), minimal modern competition, and adequate commercial real estate with heavy utility infrastructure.

Scale economics: per-machine costs decrease as size increases, commercial contracts provide predictable base revenue, WDF processing at volume achieves 40-60% gross margins, and the customer experience advantage (zero wait times, premium amenities) commands higher vend prices. Well-managed mega stores deliver 20-35% annual cash-on-cash returns.
