The Inspo is 62″ tall, and The Dupe is 65″ tall. Both have similar depths/widths.
The obvious difference here, beyond how terrible my Photoshop skills* are on The Inspo, is the base. The Inspo looks a marble roll of toilet paper, and The Dupe has a traditional brass cap.
*Click through The Inspo and tell me this wasn’t a hell of Photoshop job!
