A hand washing station includes a basin assembly having a rear configured for mounting to a wall surface and a front opposite the rear. The basin assembly includes a basin having a trough positioned proximate to the rear of the basin assembly and recessed from an adjacent surface of the basin located forward of the trough, with the trough having a front wall extending downward from the adjacent surface and a bottom wall extending rearward from the front wall. The basin assembly also includes a drain within the trough, formed by a slot extending through the front wall. A drain adapter is mounted on the trough below the basin and includes a passage in communication with the drain and extending through the drain adapter to an outlet for connection to a drain pipe, where the drain adapter receives water exiting the drain and outputs the water to the drain pipe.

A portable sink includes a container for holding wash water, an inlet line to bring fresh water into the container, and an outlet line to remove wastewater from the container. A float valve on the inlet line maintains wash water at a selected level within the container. A faucet attached to the float valve may further provide a separate source of clean water to the user. The outlet line further includes a siphon to draw the wastewater from the container to a selected discharge location. The inlet and outlet lines may form an assembly with an inverted U shape so that the device may straddle the wall of a bucket so that no piping penetrations are made through the wall. The siphon preferably includes an airlock to prevent the ingress of air at the discharge end under conditions of less than maximum flow.
