Replacing your shower head is one of the quickest, simplest upgrades you can make to your shower. Our shower heads feature a wide range of styles and innovations, and install in less than 20 minutes - no special tools required. Delta h2okinetic showers look different because they are different. Using advanced technology, h2okinetic showers sculpt water into a unique wave pattern, giving you 3x the coverage of a standard showerhead.* the result is a shower that provides more coverage, more warmth, and more intensity for a truly drenching shower experience. So go ahead and indulge, because now you can enjoy the feeling of more water without using more water. The pause setting gives you ample space for shaving, lathering, and other shower tasks, then easily restart the water with the temperature where you left off. This spray setting helps you conserve water, so you can worry less about depleting your supply of hot water - and you help the environment too. *coverage measured by EPA water sense specification for showerheads, march 4, 2010.
