A pet washing apparatus is disclosed. The apparatus includes a base, a top member, side supports, and a flexible side wall. In various embodiments, a water line brings water in from a water source such as a sink faucet. The water line is attached to a nozzle. A drain tray is placed over the base so that water used within the apparatus drains through the drain tray into the base. A pump is provided in the base to pump water out of the base through a water exit line, for example, into a sink drain. The device is collapsible such that the drain tray, side support, and top member all collapse and fit within the base. Optionally, the base has a handle and wheels.
