Which of the following is NOT a must-have in resident bathrooms?

In the context of resident bathrooms within nursing homes, minimal decoration is not considered a mandatory requirement. The primary focus in these spaces is on safety, accessibility, and function. Options like safety alarms are essential to enhance resident safety, while a working door ensures privacy and security, and accessible height vanities facilitate easier use for residents with mobility or height challenges.

While minimal decoration may contribute to a pleasant environment, it does not hold the same level of importance as the other features listed, which directly impact the health, safety, and well-being of the residents. Therefore, while it's ideal to create a homely atmosphere, the presence or absence of minimal decoration does not affect the essential operational standards for resident bathrooms.
