Quad Stone Insert Knob Faucet – Luxury Bath Fittings
Geometry enriched with natural texture.
The Quad Stone Insert Knob Faucet blends crisp architectural form with the warmth of a hand-polished stone insert. Each square knob features a refined geometric silhouette softened by natural material contrast. Modern and tactile, it elevates daily ritual through bold shape and understated luxury.
Craftsmanship in every detail.
Made in the USA from solid brass, Quad is engineered for permanence. Quad is available in a large range of finishes, from chrome to platinum and from unlacquered brass to gold plate. Sherle Wagner platinum, brass, and gold finishes contain 24K gold in our proprietary formula. All finishes are hand-plated and hand-polished by artisans in our Fall River, Massachusetts workshop.
Design with clarity and poise.
Designed with refined intention, this faucet balances sculptural form with intuitive control. Precision ceramic valve technology ensures smooth, deliberate operation, while carefully considered proportions create visual harmony within the space. Engineered for lasting performance, the design unites architectural clarity with confident, effortless function.
Part of a larger story.
Pair the Quad Stone Insert Knob Faucet with coordinating Quad fittings, accessories, or other modern Sherle Wagner collections such as Prism, Modern, or Molecule for a cohesive architectural suite. For Extraordinary Living. Since 1945.
