What is a filler in the context of kitchen planning?

In kitchen planning, a filler is specifically defined as wood or veneer strips that are inserted to fill gaps or spaces that exist between cabinetry and walls, appliances, or other cabinetry units. These fillers are essential for achieving a seamless and polished look in kitchen design, ensuring that every area is neatly finished without unsightly gaps. They can also serve functional purposes, such as allowing for slight adjustments in cabinetry alignment or accommodating the installation of trim.

This concept is important in kitchen design, as it highlights the attention to detail necessary for creating a cohesive and aesthetically pleasing space. The other options do not align with the specific role and function of fillers in this context. A decorative item, kitchen appliance, or specific type of cabinet does not serve the structural and finishing purpose of fillers in cabinetry layouts.
