According to the Alberta Building Code, what are the minimum stall dimensions for barrier-free installation?

In the context of barrier-free installations as specified by the Alberta Building Code, the minimum stall dimensions must accommodate the needs of individuals using mobility devices such as wheelchairs. The required dimensions are 1500mm x 1500mm, which provide adequate space for maneuverability and accessibility within the stall.

These dimensions ensure that there is enough room for a wheelchair to turn around and comfortably position itself, allowing for easier access and safer use of the facilities. This standard is crucial for ensuring compliance with accessibility regulations, promoting inclusivity, and enhancing the usability of public and private washrooms.

Other options represent dimensions that do not meet these accessibility requirements. While they might provide more space, only 1500mm x 1500mm meets the minimum regulatory standards outlined in the Alberta Building Code for barrier-free installations.
