Which of the following is not required for a barrier-free washroom in a residential building?

Grab bars
Barrier-free entrance
Sink with knee clearance
Bathtub with built-in seat

The correct answer is: Bathtub with built-in seat

A barrier-free washroom in a residential building is designed to be accessible for individuals with disabilities and mobility limitations. Therefore, options such as grab bars for support, a barrier-free entrance for easy entry, and a sink with knee clearance for easier reach are all required elements. However, a bathtub with a built-in seat is not a requirement as it may not be practical or necessary for all individuals. Additionally, installing a built-in seat may take up more space and potentially limit accessibility for wheelchair users. Therefore, a bathtub with a built-in seat is not required for a barrier-free washroom in a residential building.
