Why does a kitchen cabinet require two measurements? What does re-measurement mean?

Re-measurement means taking the actual dimensions again after the plumbing, electrical work, walls, and flooring are completed. The first measurement is used for the preliminary plan, and the second re-measurement is used to confirm the sink and water supply/drainage positions, gas and socket locations, the range hood exhaust path, and the reserved positions for the dishwasher and refrigerator, ensuring that the cutouts match the cabinet body dimensions. It is recommended to schedule the re-measurement after the plumbing and electrical positioning is completed, to avoid mismatches between dimensions and locations. (On-site measurement is free; no measurement fee is charged.)
