Water Onyx 4-inch centerset faucet

The Kingston Brass NB5610AL Water Onyx is a single-hole lavatory faucet supplied with a deck plate for three-hole sinks. Its black nickel finish meets ASTM B117 and ASTM B368 corrosion requirements. High-quality brass construction and a quarter-turn washerless cartridge provide drip-free operation. The included brass pop-up drain completes the installation.

Brass build and washerless cartridge headroom

Solid brass body and handles resist daily wear in busy bathrooms. The quarter-turn ceramic cartridge eliminates rubber washers that degrade over time, delivering consistent shut-off. Black nickel coating passes salt-spray and humidity tests per ASTM B117 and ASTM B368. The pop-up drain assembly is brass, not plastic, for longer service life.

Upgrade from two-handle or plastic-cartridge units

Replaces widespread two-handle faucets when a cleaner, single-lever look is preferred. The deck plate covers existing three-hole cutouts without a new countertop. Builders who need a widespread eight-inch spread or a wall-mount layout cannot use this centerset model. The jump is worth it when durability, a modern finish, and single-hole simplicity are priorities.

Questions about this item

Will the 4 inch centerset footprint cover the existing three-hole cutout in my vanity top?

Yes, the included deck plate bridges the outer holes so the single-hole mono block body mounts cleanly over a standard 4 inch spread.

How do I verify the quarter-turn washerless cartridge is functioning correctly after installation?

Turn each handle a quarter turn; water should start and stop instantly with no drips from the spout or around the cartridge housing.

Does the package include the pop-up drain assembly or must I purchase it separately?

The brass pop-up drain with matching Black Nickel finish is supplied in the box; no separate drain purchase is required.
