Which of the following is not a requirement for a barrier-free washroom in a commercial 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 Grab bars, barrier-free entrance, and sink with knee clearance are all requirements for a barrier-free washroom in a commercial building. Grab bars provide support and stability for those with mobility disabilities, a barrier-free entrance allows for easy entry and exit for individuals using wheelchairs or mobility aids, and a sink with knee clearance allows for wheelchair users to comfortably use the sink. B: A barrier-free entrance is a requirement for a barrier-free washroom in a commercial building, so this option is incorrect. C: A sink with knee clearance is a requirement for a barrier-free washroom in a commercial building, so this option is incorrect. D: This is the correct answer. A bathtub with a built-in seat is not a requirement for a barrier-free washroom. In fact, having a bathtub may even hinder accessibility for individuals with mobility disabilities. A barrier-free washroom should have an open shower area with a handheld showerhead for ease of use.
