A hand-washing apparatus configured to simultaneously wash hands includes an enclosure with openings for each hand, and members for finger support and thumb support. The finger support member extends upward from the enclosures base and the thumb support member extends along a direction different from the finger support member. The finger support has a surface for receiving and orienting fingers of both hands at corresponding locations inside the enclosure. Similarly, the thumb support has a surface for receiving and orienting both thumbs. The finger-support surface has two recess sets, each of which receives fingers of one hand. First and second spray-nozzles are directed to irrigate the fingers and thumbs respectively.
