Fixing a shower that lacks hot water requires inspecting the temperature control components. First, remove the shower handle trim and adjust the rotational limit stop (anti-scald ring) to allow a wider mixing arc. If the limit stop is correctly positioned, the internal pressure-balancing cartridge is likely worn out or fouled with mineral scale and must be replaced. Callout type="warning" title="Hygiene Warning": Shut off the main water supply before performing plumbing repairs. Verification: Test the shower water temperature after adjustment or cartridge replacement to confirm hot water is restored.
