Designed to fit to a standard shower arm, the HydroRain Two-in-One Shower Head installs in minutes. Once installed, it provides you with a luxurious shower experience and complete control over your water with a pivoting rain can and the option to use the rain can on its own, the shower head on its own, or both together. Upgrading to a new Delta shower head is a great weekend DIY project. Innovative Pause feature allows you to conserve water while lathering up.
