An access floor with removable panels is designed primarily to facilitate the easy routing of electrical, telecommunications, and HVAC systems. The clear advantage of these access floors is that they provide flexibility for configurations and adaptations in office and commercial environments.

Plumbing, however, is not suited for installation in access floors with removable panels. This is due to the potential for leaks and the need for plumbing systems to be more securely integrated into the building's infrastructure to prevent water damage, which could occur from the frequent access or movement associated with removable floor panels. Additionally, plumbing installation typically requires proper venting and drainage that cannot be effectively managed in a system designed for quick access and modification.

In contrast, HVAC components, electrical conduit, and computer cables are all generally acceptable within access floors, as they often require adjustments or reconfigurations and benefit from the ease of access that the floor system provides.
