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

Each of the other options are considered essential requirements for a barrier-free washroom in a commercial building. Grab bars provide support and stability for individuals who have difficulty standing or balancing. A barrier-free entrance allows for easy access for individuals with mobility aids such as wheelchairs. A sink with knee clearance allows individuals who use a wheelchair to comfortably approach and use the sink. However, a bathtub with a built-in seat may still present obstacles and difficulties for individuals with mobility limitations. For this reason, it is not considered a requirement for a barrier-free washroom. Instead, a barrier-free shower with a bench or seat is typically recommended.
