A barrier-free washroom in a commercial building is designed to accommodate individuals with disabilities, ensuring that everyone can access and use the facilities comfortably and safely. The requirements for such washrooms are guided by regulations that specify essential features to enhance accessibility.

Grab bars are crucial in providing support for individuals with mobility challenges, particularly when using toilets or transferring from wheelchairs. A barrier-free entrance is also mandatory, allowing individuals to enter and exit the washroom without encountering obstacles. Additionally, a sink designed with knee clearance is fundamental, enabling wheelchair users to access the sink comfortably.

The requirement for a bathtub with a built-in seat, however, is not universally mandated for all barrier-free washrooms, particularly in commercial contexts. Many commercial facilities may not include bathtubs at all, as the focus often leans more towards shower facilities or simply providing accessible toilets and sinks. Therefore, while a bathtub can enhance comfort for some users, it is not a standard requirement, making this option the correct response in identifying what is not required for a barrier-free washroom in a commercial setting.
