The Sink Cabinet has a main countertop with a cutout for the sink that is the same width as one wall or window panel. It has a middle shelf that is removable and the canvas body folds flat for storage. A hanging bracket attaches to the threaded inserts on the side panel. The counter top fits over the bracket and a clamp on the middle shelf engages the side panel ‘D’ ring to secure the counter cabinet. An optional sink top can be used. It comes with a collapsible sink and faucet. The sink is a modified collapsible tub with a drain assembly added. A standard 2 gallon pressure sprayer tank can be used for a water reservoir plumbed to the faucet. The tank can be hand pumped to provide water pressure to the faucet.
