One of the biggest differences between a regular and a rain shower head is their placement. A standard showerhead sits at an angle against the wall. But, a rain shower head will be placed parallel to the ceiling so that it sits right atop your head. A rain showerhead is supposed to mimic the gentle but consistent fall of raindrops in nature. These showerheads, therefore, tend to be wider than standard showerheads. While regular showerheads are circular or round, a rain showerhead may be square. This ensures that a wider area is covered within the shower space.  Unlike rain showers, regular showerheads spray water at a higher pressure. They also have more spray settings for a unique shower experience. Rain showers usually only have one spray setting. They are great for a soft, relaxing time in the shower. Their sleek look makes for a truly elegant fixture in one's bathroom. But, they are difficult to install and might require professional help.
