What is the minimum height for a sink installed in a residential bathroom?

The minimum height for a sink installed in a residential bathroom is considered to be 30 inches. This measurement is established to ensure that the sink is at a comfortable height for both adults and children.

In the context of residential plumbing standards, a height of 30 inches helps facilitate good ergonomics for everyday use, such as washing hands and face, which is crucial in a bathroom setting. This height also aligns with industry practices, making it a common choice for residential sink installations. Heights lower than this can lead to discomfort over extended use, while much higher installations may not be practical for users.

Understanding the standard height ensures compliance with local building codes and can also improve the accessibility of the bathroom, making it a suitable design choice in family homes or spaces that children or elderly individuals may frequently use.
