Kallista's new 12-in. Raindome showerhead uses an air-induction system to create a powerful, enveloping spray. The design features Katalyst technology, which injects air into the water drops to improve the shower's performance. The Raindome also features an enhanced nozzle configuration with 102 nozzles for greater coverage and even exposure. Both ceiling and wall-mount shower arm options come in 3-, 6- and 12-in. lengths for installation flexibility, and the air intake system for the Katalyst technology is concealed for quiet operation.
