What Is a Shower Head?
A shower head is a fixture that disperses water into a controlled spray pattern for bathing. It attaches to a flexible hose, fixed arm or riser rail and connects to a standard threaded fitting. Shower heads are available in various designs such as handheld heads, rainfall plates, multifunction spray units and fixed jets. Each design offers specific benefits for comfort, coverage and water efficiency.
Different shower heads are constructed from materials such as ABS plastic, chrome plated metal or stainless steel. Plastic models are lightweight and affordable, while metal units provide increased durability and better resistance to long term heat exposure. Understanding the material affects both longevity and maintenance requirements.
Shower heads influence the overall showering experience through spray pattern, nozzle design and flow regulation. Hard water minerals can clog nozzles over time, reducing performance and altering spray direction. Replacing the shower head provides an immediate solution to many flow related problems.
How Does a Shower Head Function?
A shower head functions by directing water through internal channels and nozzles that shape the spray pattern. Water enters through a threaded connector and flows into an internal chamber that balances pressure. The number of nozzles, their placement and their shape determine the intensity and coverage of the spray. Small precision holes create powerful jets, while wide nozzles create soft rainfall like sprays.
Many modern shower heads include flow restrictors that limit water usage. These restrictors reduce water consumption while maintaining spray comfort by controlling pressure. Aerated shower heads mix air with water to increase volume without increasing flow rate. Over time, minerals from hard water can accumulate around internal parts, reducing efficiency and causing uneven spray.
Silicone nozzles or flexible jets help prevent limescale buildup. These nozzles can be rubbed clean manually, restoring proper spray shape. Understanding how the shower head functions helps users identify issues such as pressure loss, uneven spray patterns or blockages inside the head.
