What is the minimum requirement for restroom facilities in an establishment?

The minimum requirement for restroom facilities in an establishment is that there must be at least one restroom that meets specific health department standards. These standards are established to ensure that restroom facilities are safe, sanitary, and accessible to all individuals using the establishment.

Having one restroom that complies with health department regulations ensures that it is equipped with proper sanitation features, including adequate cleanliness, proper plumbing, and sufficient supplies such as soap and paper towels. This focus on compliance is essential for public health and safety, as well as for the overall reputation of the establishment.

The other options do not meet the full requirements necessary for restroom facilities as dictated by health standards. For instance, the option mentioning a restroom with no water supply fails to provide basic hygiene requirements. A restroom that only has cold water may not meet the expectations for comfort and cleanliness in many establishments, while the option that specifies two restrooms with hot and cold water exceeds the minimum requirement, making it unnecessary as a baseline standard. Hence, the best answer emphasizes compliance with health department criteria.
