Familiar geometries and subtle curves in the Tetra™ Bath Collection combine to bring a sleek, architectural look and feel to the bath. Delta® showers with Monitor® pressure-balance valves are engineered to make sure you don't 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. Integrating separate controls on one trim with the MultiChoice® Integrated Shower Diverter allows you to simply set the water at your preferred temperature and turn the shower on or off with the volume control handle - without interrupting your set temperature. You can install with confidence, knowing Delta® products are backed by our Lifetime Limited Warranty.
