A portable body-washing apparatus is a self-supported, self-contained hygiene aid directed towards use in care-homes, hospitals, or other facilities typically tasked with assisted bathing of disabled persons. A mobile chassis supports an adjustable armature, a base chair segment, and at least one articulated chair segment to support a subject's body during washing. An onboard pump assembly and connected power supply feeds fluids from at least one fluid source through a plurality of conduits via a fluid selection source, enabling operators to select from various output modes, e.g., water, heated air, body wash, shampoo, et cetera. The plurality of conduits is connected to a plurality of outlet heads distributed across the base chair segment and at least one articulated chair segment to enable a full-body wash without requiring a caregiver to physically maneuver the patient.
