This product installs in minutes with no special plumbing needed. Use the rain can only, the showerhead only, or both at the same time for a luxurious, spa-like shower experience. Showers look different because they are different. Using advanced technology, H2Okinetic showers sculpt water into a unique pattern, giving you 3x the coverage of a standard showerhead.* The end 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. While other products may gather unsightly mineral build-up over time, Delta soft rubber spray holes allow any mineral residue to simply be wiped away for an instantly refreshed look – with no need for soaking or the aid of chemical cleaners. The pause setting gives you ample space for shaving, lathering and other shower tasks, then easily restarts 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.
