Benchmarking Bathroom Sink Faucets — What Architects Need to Know
Covering compliance, WaterSense flow targets, touchless controls, ADA, tempering, serviceability, and documentation. Here is a focused comparison of five leading brands bathroom sink (lavatory) faucets for commercial and hospitality projects —
Introduction
Lavatory faucets in public and hospitality restrooms are high‑touch (and increasingly touchless) interfaces that affect water safety, occupant health, accessibility, and conservation. For architecture and MEP teams, bathroom sink faucets must be specified with attention to certification (cUPC, NSF/ANSI 61 & 372), efficiency (EPA WaterSense), ADA reach/operability, mixing and scald protection (ASSE 1070/CSA B125.3), and long‑term serviceability. This guide benchmarks five widely specified brands through a faucet‑specific lens and links directly to authoritative resources for submittals.
