A self-contained pet washing and grooming apparatus is disclosed. The apparatus includes a base, a top member which is a grooming compartment, 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 has a power source, and is collapsible such that the drain tray, side support and grooming compartment all collapse and fit within the base. Extension legs attached underneath the base are also collapsible. Optionally, the base has a handle and wheels.
