For installation in an employee restroom, a urinal requires not less than a _____ -inch clearance from the center line of the fixture to a wall or partition.

The requirement for a urinal to have a minimum clearance from the centerline of the fixture to a wall or partition is critical for ensuring accessibility and proper usage. A clearance of 15 inches allows sufficient space for individuals to approach and use the urinal comfortably. This measurement is based on industry standards that take into account the average space needed for users to avoid any obstruction and to accommodate different body sizes and mobility aids.

This clearance ensures not only comfort but also compliance with accessibility guidelines for restrooms. The standardization of such measurements helps in promoting a functional and user-friendly environment in public and employee restrooms, aligning with best practices in plumbing installations.
