## Description

For a bathroom vanity or RV sink that needs a dark, modern update, the Cobbe CB-11003B pairs a matte black finish with an open waterfall-style spout and two separate lever handles.

Its 4-inch centerset design is listed for 2- or 3-hole sink setups. The package includes a pop-up drain and hot- and cold-water supply hoses, so it covers several of the main parts needed for a faucet replacement.

Would the waterfall shape suit a sink you use every day? It gives the faucet a more distinctive look than a conventional enclosed spout, while the dual handles let you adjust hot and cold water separately.

## Tech summary
- Model: CB-11003B
- Type: Deck-mount bathroom faucet with waterfall spout
- Finish: Matte black
- Material: Stainless steel
- Mounting: 4-inch centerset, listed for 2- or 3-hole sinks
- Flow rate: 1.2 gpm
- Spout height: 5.24 inches
- Spout reach: 6 inches
- Included: Pop-up drain, two 24-inch hot- and cold-water hoses, instruction manual

## Compatibility & requirements
The faucet is intended for bathroom sinks, vanities, powder rooms, and RV use. Its listed installation hole diameter is 1.06–1.5 inches, and the maximum deck thickness is 1.6 inches. Compare those measurements and the centerset layout with your sink before choosing it, a faucet’s hole pattern and deck clearance matter as much as its appearance.

The supplied 24-inch hoses connect the hot and cold sides, and the two lever handles sit on either side of the spout. That layout is suited to a traditional two-handle setup rather than a single-control faucet. The stated 1.2 gpm flow rate is a useful point of comparison if you are replacing a faucet and want to consider its listed water output.

## Getting the most from it
The open spout makes the waterfall profile the main visual feature, while the black finish can work with modern or farmhouse-style decor. In a powder room, it can make the sink area feel more deliberate, in an RV, the compact centerset arrangement may suit a sink with the matching hole layout. The included pop-up drain also keeps the drain style coordinated with the faucet.

Buyers often praise the straightforward installation and the handles’ solid feel. Feedback is less consistent on water flow, and some buyers report dripping after shutoff or peeling of the black finish during regular use. Those reports are worth weighing alongside the faucet’s appearance and included parts, especially if long-term finish condition and leak-free operation are your main priorities.

## When it makes sense
It’s a great fit if you want a two-handle, matte black waterfall faucet for a compatible 4-inch centerset sink and value having a drain and supply hoses included. Compared with a more conventional spout, this design puts more emphasis on the visible water flow and the sink’s look. You may want to skip it if reports of finish wear or post-shutoff dripping would outweigh the styling benefits for your household.
