An adjustable platform assembly for raising an appliance includes a platform with various spaced vertical leg members. Each of the leg members has a first mounting aperture for fixing an appliance to the platform, and a second mounting aperture for fixing an adjustable caster to the leg member. A consumer can adjust the platform assembly to a desired height by altering the height of the caster members. A decorative faceplate is provided which removably attaches to the front of the platform assembly to give the appliance a built-in look.
