How many days does whole-house customization installation take to complete?

There is really no way to give a definitive answer to how many days installation takes in one sentence; it depends on the number of cabinets and the on-site conditions. The general process is: an on-site measurement is scheduled within 1–7 days, the processing cycle is usually 15–45 days, logistics delivery takes 1–3 days, and only after that does installation begin. Installation itself usually takes one to three days; it will be delayed if there are many cabinet bodies, worktop cutouts for kitchen cabinets, or complex wall finishing. So do not just ask how many days installation takes; factor in the measurement and processing scheduling first, and only then will the overall timeline be reliable.
