2. Disconnect the old shower hose
Remove the showerhead from the holder and unscrew it anti-clockwise. If the connection is tight, you may need to use a pair of pliers with a rag wrapped around the hose joints to prevent damage. Take care not to lose the hose washer. If it’s in good condition, you can reuse it. Then, disconnect the hose from the water outlet, unscrewing it anti-clockwise, ensuring you keep the washer safe. Some residual water may pour out of the hose at this stage.
