A disciplined expression of modern geometry.

The Keystone Knob Wall Mount Bathtub Faucet brings sculptural restraint to contemporary bath environments. Its crisp cylindrical knob and horizontal projection create a composition rooted in proportion and clarity, offering a clean architectural line that transforms daily ritual into a moment of intentional design. Minimal yet expressive, it complements interiors where simplicity carries visual weight.

Craftsmanship in every detail.

Crafted in the USA from solid brass or bronze, Keystone is engineered for permanence. Available in a wide range of Sherle Wagner finishes, each piece is hand-plated and hand-polished by artisans in our Fall River, Massachusetts workshop.

Design with clarity and poise.

Designed for wall-mounted installation, this bathtub faucet delivers full, immersive flow for a luxurious bathing experience. Its carefully proportioned spout creates visual balance across a range of wall-mounted configurations, while precision ceramic valve technology ensures smooth, reliable control. Engineered for enduring performance, the design brings architectural clarity and effortless function to the bath.

Part of a larger story.

Pair the Keystone Knob Wall Mount Bathtub Faucet with other modern Sherle Wagner collections such as Dorian, Modern, or Prism to create a unified contemporary suite.
