The prismatic faceting of the Trillian Bath Collection is an evolution of modern style that creates an edgy look which catches the light as well as the eye. Delta showers with Monitor pressure-balance valves are engineered to make sure you dont 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. With separate handles for volume and temperature control, this Delta valve provides a more refined showering experience. 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 that Delta showers are backed by our Lifetime Limited Warranty.
