Inspired by the sleek lines of contemporary European design, this Grail Single-Handle Valve Trim in Chrome combines an urban look with a delightfully intimate feel. Delta's dual-function thermostatic valve cartridge keeps water temperature consistent (within 3.6?) by actually measuring and monitoring the temperature of the water and automatically adjusting the water mix to maintain a more precise water temperature. Temperature can be set in order to remain consistent shower after shower.
