Thank you for your question. Your Delta roman tub trim can be changed out without having to change the valve body in your deck of your tub. The way to confirm this is to check your roman tub spout to see if a set screw is on the back of the spout. All of our new trim kits have spouts with set screws on the back. If your spout assembly has a set screw in the front of the spout, no new trim will retrofit on the existing valve. The Ashlyn T2764 will have just the trim kit, not a new valve body.
