What Is a Bathroom Faucet?
Bathroom (lavatory) faucets control water flow and temperature at a sink, and are categorized primarily by mounting configuration: single-handle faucets combine hot/cold control in one handle over a single mounting hole; centerset faucets have two handles and spout mounted on a single base plate over a 4-inch hole spread; widespread faucets have separate hot, cold and spout components connected by flexible supply lines, mounted on wider hole spacings (commonly 8 inches) for a more custom, upscale appearance.
Internal valve type determines durability and feel: ceramic disc cartridges are the current standard, offering smooth operation and long service life resisting mineral buildup and wear far better than older compression (washer) valves. Faucet and sink hole spacing must match exactly — a widespread faucet cannot mount to a single-hole sink and vice versa — so confirming the sink's existing hole configuration (or specifying it for new construction) is the first step before selecting a faucet.

| Spec | What It Means | Why It Matters |
|---|---|---|
| Mounting Configuration | Single-hole, centerset (4 in), widespread (8 in) | Must match the sink's actual hole spacing — configurations are not interchangeable |
| Valve Type | Ceramic disc, compression (washer), ball | Ceramic disc offers the longest service life and smoothest operation of common valve types |
| Flow Rate | Typically 1.2-1.5 GPM per WaterSense/code | Many jurisdictions mandate a maximum GPM for water conservation compliance |
| Finish | Chrome, brushed nickel, matte black, bronze | Cosmetic and corrosion-resistance choice matched to the bathroom's fixtures and water hardness |
| Drain Assembly | Pop-up drain often included or sold separately | Confirm whether the faucet includes a matching drain or one must be purchased separately |

FAQ
Bathroom Faucets Questions, Answered
How do I know if I need a centerset or widespread faucet?
Measure the existing sink or countertop's pre-drilled hole spacing: a single hole takes a single-handle faucet, holes spaced 4 inches apart (center to center) take a centerset faucet, and holes spaced 8 inches or more apart take a widespread faucet. These configurations are not interchangeable, so confirm the actual hole spacing before ordering, especially when replacing a faucet on an existing sink or countertop.
What's the advantage of a ceramic disc cartridge over a compression valve?
Ceramic disc cartridges use two hardened ceramic discs that rotate against each other to control flow, resisting mineral buildup and wear far better than older rubber-washer compression valves, which require periodic washer replacement as they wear and are more prone to dripping over time. Most current faucets use ceramic disc cartridges as the standard.
Do I need to check my local plumbing code for maximum flow rate?
Yes — many US states and municipalities mandate a maximum flow rate (commonly 1.2 or 1.5 GPM for bathroom faucets) for water conservation, sometimes stricter than the federal WaterSense baseline, so confirm the applicable flow rate limit for your jurisdiction before specifying a faucet, particularly for new construction or renovation permits.
Does a widespread faucet come with the supply lines and drain included?
This varies by manufacturer and product line — some widespread faucet kits include matching supply lines between the handles and spout, while others require these purchased separately, and pop-up drain assemblies are also sometimes sold separately from the faucet itself. Check the specific product's included-components list before ordering to avoid a missing-parts installation delay.
Can I replace just the cartridge instead of the whole faucet if it's dripping?
In most cases yes — a dripping single-handle or two-handle faucet is commonly caused by a worn cartridge, and replacing just the cartridge (matched to the faucet's specific brand and model) is a standard, lower-cost repair rather than replacing the entire faucet, provided the faucet body itself isn't damaged or corroded.
