Mineral deposits and debris can significantly restrict water flow. Carefully remove your shower head and soak it in a solution of white vinegar overnight to dissolve buildup. Alternatively, use a commercial cleaner like CLR, following the product instructions carefully.

If cleaning the shower head doesn't solve the problem, check your shut-off valve. Locate the valve under the shower and ensure it's fully open. A partially closed valve will drastically reduce water pressure.

If the pressure remains low, it’s time for a new shower head. Look for models specifically designed for low water pressure. Features like smaller nozzles or air injection technology can significantly increase the perceived water pressure. Consider your budget and preferred shower experience (rain shower, massage, etc.) when making your selection.
