On my checklist for 'must include' in bathroom remodels is the hand shower. For those who have never used a hand shower, many ask 'Why do I need a hand shower, I've been just fine without one?" Good question! Just think of the hand shower as a parallel to the sprayer in your kitchen sink. A hand shower is connected to the wall via a hose so you can 'hose' down particular areas of the tub/shower in cleaning as well as hose yourself down without having to strategically stand in 'the spot.'
These are added features to the real benefit - hand showers can be used for people of different heights such as the taller of our species as well as the small ones we refer to as children. Hand showers can be used by people who are sitting down whether on a bench or in a wheel chair. They allow YOU, the person holding the hand shower to direct the water to or away from your body. Many hand showers have a selection of shower styles, from forceful to raindrop style (ala Northwest), so you can imagine yourself at the base of Mount Saint Helen during the blast or naturally moisturizing yourself in the produce section of your local grocery store. There is a shower style that fits everyone. And with a hand shower, everyone can shower.
