A Cabinet
The dry sink was essentially a rectangular cabinet that facilitated washing just as the kitchen sink is used today, It was used in the kitchen or on the back porch to wash dishes, utensils, fruits and vegetables.
The Basin
A large steel or tin basin was placed on top. It would be filled with water from the well or the main water spigot of the home. Soap would be added if dishes were to be cleaned.
Storage
The cabinet had storage underneath to house supplies. Some cabinets had storage on the top back of the cabinet as well. Ikard said towels, other supplies and food would often be stored below.
Backsplash
Most dry sinks had a backsplash and rimmed sides to prevented spillage. It also kept walls, or anything behind the sink, from getting wet while washing.
Water Resistent
Some dry sinks had copper- or tin-lined surfaces. This prevented water from remaining on the wood and damaging it. However, Ikard said, most dry sinks had a simple wood surface.
