What is the typical depth of base cabinets, not including the countertop?

Base cabinets are an essential component of kitchen and bathroom design, typically serving as support structures for countertops and storage solutions. The standard depth of base cabinets, without including the countertop, is generally 24 inches. This dimension is widely accepted in the industry and allows for adequate space for kitchen appliances, plumbing, and work areas.

Choosing a depth of 24 inches provides sufficient interior space and ensures that the base cabinets align well with countertops, which are usually 25 to 26 inches deep when accounting for overhang. This standard depth also accommodates common kitchen applications, such as the requirement for knee space underneath countertops for seating, as well as the integration of standard appliances.

Although options for 18, 20, and 22 inches might exist for specialized cases or custom builds, they do not reflect the typical industry standard for base cabinets. Therefore, the depth of 24 inches is recognized as the norm, making it the correct choice in this context.
