Abstract: The portable shampoo sink is a sterilizable apparatus that permits bedridden individuals to have their hair shampooed while lying down. The apparatus may be used in a hospital or at home. A rolling cabinet on wheels has a sink shaped with a semicircular depression for receiving the neck or head of the individual. The cabinet stores both hot and cold water in tanks disposed within the cabinet. A motorized heater heats the water in one tank. Water is pumped up to a spray nozzle via a flexible conduit as controlled by a control on the sprayer and hot and cold water spigots. The wastewater collected in the basin drains through a conduit into a waste/drainage collection tank disposed under the basin. Two side doors permit access to the tanks, heater and pump. The sides of the cabinet have shelves for placement of washing accessories such as shampoo and the like.
