Prepare yourself for the feeling of more water with h2okinetic technology. H2okinetic provides a truly better shower experience. The warm, drenching water coverage is the result of a denser water pattern and larger droplets that retain their heat longer to soothe and revitalize. Delta's dual-function thermostatic valve cartridge keeps water temperature consistent (within 3.6) by actually measuring and monitoring the temperature of the water. Temperature can be set to remain consistent shower after shower.
