Final answer:
Grab bars may be required to be installed in residential dwelling unit toilets or bathrooms to provide stability and support for people with disabilities.
Step-by-step explanation:
In residential dwelling units, grab bars may be required to be installed in toilet or bathrooms.
Grab bars are structural supports that can be installed in bathrooms and toilets to provide stability and support for people with disabilities or those who may have difficulty maintaining balance. They can help prevent falls and provide assistance for individuals who have difficulty sitting down or standing up.
The specific requirements for grab bars vary by jurisdiction and may be outlined in accessibility codes or guidelines. In the United States, for example, the Americans with Disabilities Act (ADA) provides standards for accessibility in public accommodations and commercial facilities.
