The latest addition to California Faucets’ popular European-inspired “E” collection, Libretto is clean and minimal. The single lever faucet blends lines and curves, bringing out the softer side of contemporary design, the company notes. The solid brass faucet delivers water in a vertical sheet for a “waterfall” effect. The Libretto is available in two sizes — 12-5/16” size as well as a more compact 6-3/8” size — and 28-plus artisan finishes.
