In Australia, the installation of floors or the kitchen depends on personal preference, but generally, it is recommended to install the flooring first. Installing the flooring before the kitchen allows for a more seamless and stable installation of the cabinetry and appliances. It also makes it easier to install the flooring around the kitchen cabinetry, rather than having to cut the flooring to fit around the cabinets. Additionally, installing the flooring first can help protect the floors from scratches or damage during the kitchen installation process. However, if you are planning a major kitchen remodel that involves moving walls or changing the layout significantly, it may be better to consult with a professional to determine the best order of installation.
