Yes, showers and tub/shower diverter valves frequently benefit from or require water hammer arrestors. Because modern single-handle shower mixing valves and ceramic cartridges close instantaneously to shut off high-velocity water flow, they generate severe hydraulic shock waves (water hammer) that rattle internal wall pipes. Installing dedicated water hammer arrestors on the hot and cold supply lines near the shower valve absorbs this shock wave, protecting your plumbing infrastructure from premature joint failure. Verification: Inspect access panels behind shower fixtures to see if arrestors are installed.
