Hello Ali! The only determining factor on the trim you can replace this model with, would be the set screw placement. If the set screw is on the back of your spout, then any current T27 roman tub trim will work with either rough in valve. If you have an anti swivel pin in the front, many models could also work, however they may not fully cover the existing hole in the deck. The R2707 utilizes jack screws which can be adjusted above the deck. If you do not see a silver washer with a screw below it after removing the handles, then you have the R2700 rough valve.
