What are the four types of laundry services?
The standard four-type classification: (1) Self-service laundromats (you wash your own at coin-operated machines, 50-150 THB/load in Bangkok). (2) Wash-and-fold (drop off, staff wash and fold, you pick up; 60-200 THB/kg). (3) Dry-cleaning (chemical solvent for structured suits and delicate fabrics; per-item pricing). (4) Mobile pickup-and-delivery (rider collects from your hotel, returns clean; 200 THB/kg + 100 pickup fee at premium tier). Each serves a different need — most Bangkok tourists use (4) for convenience and (1) only when budget is tight.
