PRODUCT FEATURES
The Delta® Bonacci™ Bath Collection brings the tranquility of nature into your home with soft lines and elegant curves. Purposefully designed to simplify installation and enhance everyday use, this nature-inspired collection stands up to daily life and works beyond its beauty. The Delta MultiChoice® Integrated Shower Diverter provides a sleek, streamlined style for your shower while eliminating the need for an additional diverter valve.

With the MultiChoice Universal system, you also have the freedom to upgrade style and functionality later. Complete the look in your shower with a Delta shower head and hand shower, available with a variety of sprays and innovative features. You can install with confidence, knowing that Delta products are backed by our Lifetime Limited Warranty and highly trained, live customer support.

The specifications mention a Stainless “finish”, but what is the trim actually made of? Plastic, aluminum, etc..
Hello,
Thank you for contacting Delta Faucet Company! I am sorry this information was not readily available, and I am happy to help you!
Our Delta faucets are made of several materials and may depend on which model you have. We can't provide that level of detail every time and specific amounts are considered proprietary (trade secret).
But in general, the faucet may contain:
Bronze
Brass (36000, 260) (hub, handle, body, tube, fittings)
Zinc (escutcheon, hub, handle)
Stainless Steel (undercover plate, seat liner, set screw)
Copper (tubing)
PEX-C (puck and tubing)
Silicone (gaskets)
Synthetic rubber - EDPM, Santoprene (hoses)
Vinyl (hoses)
Nylon
Plastics
Our SS- Stainless steel is a PVD finish, PVD (Physical Vapor Deposition) is a process used to create a very durable, corrosion and tarnish-resistant finish. This process is commonly used for bathroom fixtures and entry hardware, which are exposed to frequent moisture and/or salt air.
