Thank you for your questions. The Delta Leland Tub Shower Trim T14478-SSSHCCER model comes with the non-metal pull-up diverter tub spout RP42915SS. The RP41591SS is a metal tub spout assembly and is available for ordering separately. You would need to order a Delta MultiChoice Universal Rough-In Valve R10000-UNBX separately to complete the unit installation. A back-to-back installation is two shower or tub shower units are sharing a wall or being installed back to back.
