Shady Shoals looks like most of the other buildings in Bikini Bottom: Tall and metal with windows that look like portholes. It has two rusty-colored smoke stacks on it, one on the top, and one on the lower left side. On the upper right is a periscope. Below it is a fishing pole holding up a sign that says Shady Shoals Rest Home. There is a small, wooden deck leading up to the front door.
Through the front door lies the front lobby. There is a front desk with two doors behind it, one to the left, and one to the right, where visitors sign in.
Through the left door behind the front desk is the main area. There are a few checkerboards, some coral plants, water fountains, a couch and an old T.V. Here is where the residents come to go about their day. They can play checkers, get a drink of water, watch T.V., or just mingle.
Through a door in the back of the main area is the cafeteria. It is where residents come to get their meals. There are tables where the residents eat, and the kitchen where they get their food. The floor has a yellow-and-white checkered pattern. Bingo is also held here.
Through the door to the right of the front desk is the residential area. This is where the residents live. Each room has a couch, an old T.V., and a desk.
