The dining room boasts the original Federal-style mantle with a mirror on top, along with a small section of the wall that still maintains the early 19th-century hand-painted decoration. The room is furnished with several pieces of furniture that were owned by the Johnstons, including a large cherry china press from the mid-18th century, a walnut pie safe from around 1850, a sideboard from the late 1800s, and a cherry banquet table from between 1820 to 1840, which has two half-moon extensions. One of the extensions was created in the 1950s by a local cabinet maker named Harvey Niday to replace the original. The room features eight mahogany Empire-style chairs from the 20th century and a modern oriental-style carpet that matches the period. The lighting fixture was installed during the restoration period and is also of the same period.
