The Delta® MultiChoice® Integrated Shower Diverter consolidates custom shower design with its consumer-preferred streamlined style eliminating the need for an additional diverter valve. The contemporary round style is a smooth take on modern geometrics, offering a fresh look which can complement a wide range of decor. With three popular style choices to coordinate with any bathroom décor, it provides you the flexibility to select the type of custom shower functionality you prefer. With the MultiChoice® Universal system, you have the freedom to upgrade style and functionality later. And, because there’s no need to alter plumbing behind the wall, you save time, effort and money on future renovation updates. 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 in order to remain consistent shower after shower.
