Install Internal Cabinetry and Shelving

What happens here

Once the main frames are stable, proceed with installing any internal shelving or partitions that will define the storage areas or provide support for specific components like sinks or small appliances. For a wet bar setup, consider reinforcing the section designated for a sink and its associated plumbing. Ensure these internal structures are securely fastened to the main frames. This step also involves fitting the cabinet backings if they are part of the internal structure.

Goal: Integrate internal shelving and structural elements within the assembled bar frames to create functional storage compartments and supports for appliances.
