Wainscoting is a decorative wall treatment that involves installing wooden panels along the lower part of a wall. It adds elegance and character to a room while also protecting the walls from damage. Traditionally, wainscoting was made from solid wood, but today it can be found in various materials, including MDF and plywood, making it more accessible and affordable for homeowners. This design element can be painted or stained to match the room's decor, allowing for endless customization. Wainscoting is often used in dining rooms, hallways, and living rooms, creating a classic look that enhances the overall aesthetic of a space.
