Thank you for your question. Delta does not make an shower arm extension for the shower heads. However, we do manufacture a 16" long shower arm RP61273CZ that would work with the Delta Cassidy Tub and Shower Trim T14497-CZLHP. Please see the below link for the different style available handles (H795CZ, H797CZ and H978CZ) for this model.
