Natural lighting is not required in which room if adequate ventilation is provided?

Natural lighting is not mandated in a bathroom if adequate ventilation is supplied. The primary concern in bathroom design is moisture control and airflow, which helps prevent issues like mold and mildew. Adequate ventilation can typically be ensured through the use of exhaust fans, operable windows, or a combination of both.

In many building codes, rooms such as living rooms, kitchens, and bedrooms are generally required to have natural light for comfort, safety, and aesthetics, contributing to quality living environments. However, bathrooms are often treated as unique spaces where privacy is paramount, and the focus shifts towards functionality and health rather than natural light. This is why providing sufficient ventilation can suffice in meeting the requirements for these spaces without the necessity of natural light.
