Tighten the showerhead with a wrench or apply plumber’s tape to the threads before reattaching it. If the leak persists, replace the washer inside the showerhead.

Remove the old seal, clean the track, and insert a new seal by pressing it firmly into place along the door edges.

Check for flow restrictors that can be removed or adjusted, clean mineral deposits from the head, and ensure your home's water pressure meets the shower head's requirements.
