How long do new kitchen cabinets take to arrive?

Four to six weeks for semi-custom, eight to twelve for full custom, and days for stock sizes. This is the single number that sets a kitchen renovation schedule, because nothing after demolition can be finished until the cabinets are installed, and the countertop cannot even be measured. Order them before demolition day, not after. A project that starts with the walls coming out and the cabinets still unspecified will sit unusable for a month in the middle.
