Ontario Building Code Practice Exam

Which of the following is not a requirement for an accessible washroom in a commercial building?

1. Grab bars

2. Barrier-free entrance

3. Sink with knee clearance

4. Bathtub with built-in seat

The correct answer is: Bathtub with built-in seat

An accessible washroom in a commercial building is designed to be usable by individuals with various disabilities, ensuring that they have access to essential facilities. While grab bars, barrier-free entrances, and sinks with knee clearance are critical features that support accessibility, the inclusion of a bathtub with a built-in seat is not typically a requirement for accessible washrooms in commercial settings. In most cases, accessible washrooms are focused on providing facilities such as toilets, sinks, and hand dryers rather than bathing facilities. The presence of bathtubs is generally more associated with residential settings or specific types of facilities where bathing is a primary function, such as healthcare or rehabilitation centers. Thus, while it might be beneficial to have a bathtub with a built-in seat in certain contexts, it does not meet the standard requirements for accessibility that apply to commercial washroom design as outlined in building codes.
