A vertical plane is any plane where the normal (a line at 90 degrees to the plane) is horizontal. All your walls are vertical planes. The normal to the plane of the Earth's orbit is often used to define "up" and "down" for planet Earth. The Earth's axis is tilted at about 23.5 degrees away from this "vertical" line. Also you could define "vertical" as simply the direction shown by a plumb line. That's the definition which has walls as vertical planes. With either definition there will be more than one plane that is a vertical plane.
In structural geology, pitch is the inclination of a planar feature (such as a bedding plane or fault) measured perpendicular to its strike direction. It describes the steepness of the feature as it dips into the Earth's subsurface. Pitch is often represented as an angle measured from the horizontal plane.
