Designed to look like new for life, Brilliance finishes are developed using a proprietary process that creates a durable, long-lasting finish that is guaranteed not to corrode, tarnish or discolor. While other products may gather unsightly mineral build-up over time, Delta soft rubber Touch-Clean spray holes allow any mineral residue to simply be wiped away for an instantly refreshed look � with no need for soaking or the aid of chemical cleaners. Delta pressure-balance valves use Monitor Technology to protect you and your family from sudden temperature changes. This glossy finish provides a delicate elegance that can make almost any room pop. The polished surface reflects back deep shadows from your space, creating contrast within the pale gold tones which takes on a new light from every angle.
