Ontario Building Code Practice Exam

Which of the following is not required for a barrier-free 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

A barrier-free washroom in a commercial building is designed to be accessible and usable for all individuals, regardless of their physical abilities. As such, it should have features such as grab bars for support, a barrier-free entrance for easy entry, and a sink with knee clearance for ease of use while seated. However, a bathtub with a built-in seat is not necessary for a barrier-free washroom. This is because a bathtub may be difficult for individuals with mobility issues to get in and out of, and a separate shower with a handheld showerhead is often a more appropriate and accessible option. Additionally, a built-in seat may not provide enough support or stability for individuals with disabilities. Ultimately, a bathtub with a built-in seat is not required for a barrier-free washroom and may actually hinder accessibility for some individuals.
