What is the maximum number of resident rooms that a toilet room can serve if adjacent to resident rooms?

In Indiana's health facility regulations, the design and configuration of toilet facilities are essential to ensuring resident privacy and comfort. A toilet room that is located directly adjacent to resident rooms can optimally serve up to two resident rooms. This limit is based on the principle that maintaining a manageable number of residents per toilet helps to uphold sanitary standards and provides sufficient access without congestion.

Having more than two resident rooms sharing a toilet would likely lead to conflicts over usage and create potential hygiene issues. The design standards aim to enhance residents' quality of life by providing adequate facilities without overcrowding, thus striking a balance between efficiency in facility design and the needs of residents.

The other options suggest serving too few or too many residents, which does not align with the established guidelines to promote dignity and accessibility for individuals living in the facility.
