To fix a shower faucet that won't turn off all the way, start by turning off the water supply to prevent flooding. Next, remove the faucet handle, which usually requires unscrewing it or removing a cover to access a screw. Inspect the cartridge inside for any visible damage; if it's faulty or worn out, replacing the cartridge is your best bet. In cases where the issue is not with the cartridge, check for mineral deposits or debris that might be obstructing the valve's closure, and clean it accordingly.
