Installing cabinets on a floating floor is not recommended, as the weight of the cabinets can compromise the floor's ability to expand and contract. This is especially true for base cabinets, which should be avoided altogether. Kitchen cabinets can be installed on a floating floor, but it is best to place them first and then install the floor around them. If you are using CoreTec as a floating floor, you will need to install the cabinets first and have the floor outline them.
When remodeling a kitchen, it is best to install the floor before the cabinets. Unless there are drastic changes in relative humidity, the floor won't move much and kitchen cabinets can be installed directly above it. If you are working with an empty space, it is easier to place the entire surface without hassle and then install the cabinets. Cabinets should be hung from the wall by a system of railings, which bear most of the weight.
Adjustable legs on the front of the cabinets help level and support them. It should be noted that any damage that may be due to reasons other than the installation of the cabinet and the problem area is where the cabinets are located (i.e., scratches, etc.).
