The Zura design is a precise marriage of rounded, rectangular and triangular elements and offers innovative, geometric styling to complement our current contemporary lineup. All Delta tub and shower faucets are engineered to keep the water temperature within a safe 3.6 F (1.7 C)*. This technology makes sure your family doesnt experience a sudden and possibly unsafe change in water temperature as a result of running water elsewhere, such as using a dishwasher, flushing a toilet or running a washing machine. Installing a Delta MultiChoice Universal Valve makes it faster, easier and less expensive to upgrade style, finish and functionality later.
