What is the minimum clear and unobstructed finish-width for an access and egress opening for a shower?

The minimum clear and unobstructed finish-width for an access and egress opening for a shower is 22 inches. This dimension is crucial for ensuring that individuals can enter and exit the shower space safely and comfortably. A width of 22 inches allows for ease of access, particularly for individuals with mobility challenges or when assistive devices are needed.

This measurement is established to comply with building codes and safety standards, which aim to prevent hazards such as slips and falls that can occur in cramped spaces. Ensuring that this opening is sufficiently wide not only promotes safety but also enhances user experience by allowing for sufficient space to maneuver within the shower area.
