Thank you for your inquiry! As long as the screw holes on your large round escutcheon plate are at the 1 and 7 o'clock positions and you do not have a push button shower diverter directly below the off and on handle, then any of the Delta tub and shower trim kits that start with a T17, except for the T17T series trim kits will interchange for you and you do not have to replace the valve behind the wall. The Delta Victorian Shower Trim kit T17255-SS would be a correct closest matching finish model number for your original unit. The cartridges that come with the new trim kit will not fit your valve body, so you will need to reuse your existing cartridge (RP32104).
