Kitchen cabinets are typically not directly attached to the floor. Instead, they are typically installed on the wall and supported by a combination of wall studs and a suspension rail or cleat system. This installation method allows for easier access to the floor for cleaning purposes and provides flexibility in terms of cabinet placement and adjustment.
The base cabinets, which rest on the floor, may have a toe kick space at the bottom for ergonomic purposes and to allow for easy cleaning. The toe kick space is usually a recessed area beneath the cabinet doors that provides a comfortable space for your feet when standing at the countertop.
However, it's worth noting that there are certain instances where kitchen cabinets may be secured to the floor for stability and additional support. This is more common in situations where there is a need for extra reinforcement, such as in areas prone to earthquakes or where heavy appliances are installed within the cabinets. In such cases, the cabinets may be anchored to the floor using brackets or screws.
Ultimately, the specific installation method may vary depending on the design, construction, and requirements of the kitchen cabinets and the individual preferences of the homeowner or installer.
