Abstract: A modular faucet assembly is configured for installation upon a conventional sink top having left and right hot and cold water control valve passages and a central faucet assembly passage. The present modular assembly includes a single, central faucet and mixer control valve, with all water lines extending through the central sink top passage and the left and right sink top passages remaining free of any water supply lines. The present assembly makes use of these otherwise unused passages by having left and right faucet base passages which align with the corresponding sink top passages, and serve to secure the faucet assembly to the sink top and accept various accessories removably installed therein. The accessories may comprise a liquid soap dispenser pump, a retractable spray nozzle, or other device(s) as desired. A cap(s) may be installed at the accessory passage(s) when no accessory or accessories are installed.
