This project outlines the steps to replace your shower trim. It begins by emphasizing safety and turning off the water supply. Next, you remove the existing handle, often secured by a setscrew requiring an Allen wrench. After the handle is removed, the escutcheon and any additional trim pieces are carefully removed, sometimes requiring unscrewing or prying. Then, you install the new trim components according to the manufacturer's instructions, typically screwing or fastening them into place. Finally, the water supply is slowly turned back on, and all connections are checked thoroughly for leaks. If leaks are detected, connections are tightened, or components are disassembled and reassembled as needed. A qualified plumber should be contacted for persistent leaks.
