There are four types of showerhead: fixed, handheld, adjustable, and combination. Fixed heads are the most common. They usually mount in a wall above the shower valve, or sometimes in the ceiling for a rainfall effect. Handheld showerheads give you the fixed-head spray but also can be dismounted to scrub feet, legs, pits, and of course, the family pet. Adjustable fixtures incorporate an articulated arm, which is good for changing the angle on different body types. Combination showers have both a fixed head and a handheld fixture that works independently.
