This Cassidy TempAssure 17T Series 1-Handle Volume and Temperature Control Valve Trim Kit in Champagne Bronze (Valve Not Included) is the obvious choice for a timeless, traditionally-styled bath. 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. Inspired by an 1800s ad for a Victorian corset, elegant details add visual tension. The Cassidy collection's classical design plays off of the hugely popular Victorian-esque architecture. Material: Metal.
