A single hole bathroom faucet combines the spout and the mixing valve in one body that drops through a single opening in the sink or counter. One lever or knob sets both temperature and flow. It is the simplest layout to install and to keep clean, and it suits powder rooms, small vanities, vessel sinks and anyone who wants a minimal counter. This compact range of under 20 faucets covers brass, chrome, gold and black options, including waterfall spouts and tall vessel styles.
How a One-Hole Mixer Works
Inside most of these faucets sits a ceramic disc cartridge. Lifting the lever opens the discs for more water; turning it left or right blends hot and cold. Ceramic cartridges are durable and drip resistant, and when one eventually wears, the cartridge alone can usually be replaced. Titles here often say basin mixer or hot and cold water mixer, which describes this same single-valve design.
Will It Fit Your Sink?
Start with the holes already in the vanity top.
- One hole: any faucet in this range fits directly.
- Three holes at 4 inches (centerset): you can still use a one-hole model with a matching deck plate that covers the outer holes. Check that the plate spans 4 inches.
- Three holes at 8 inches or wider: most deck plates are too small; a two-handle design from our widespread bathroom faucets is the better match.
- No holes (vessel bowl on a counter): pick a tall spout that clears the bowl rim.
The standard faucet hole is about 1 3/8 inches across, and most mounting shanks fit counters up to roughly 1 1/2 to 2 inches thick, which covers typical stone and quartz tops.
Standard Height, Vessel Height and Waterfall Spouts
Spout height matters more than many buyers expect. A standard bathroom single hole sink faucet is short and meant for undermount or drop-in sinks. A single hole vessel sink faucet is much taller, so the spout clears a bowl that sits on top of the counter; measure from the counter to the rim of the vessel and add a few inches of hand space.
A waterfall single hole bathroom faucet uses a wide, open spout that releases a flat sheet of water. It looks striking, but the flow can splash in shallow basins, so pair it with a sink that has some depth. Check spout reach, too: the water should land near the center of the bowl, not at the back near the drain overflow.
Finishes: Chrome, Brass, Gold and Black
Chrome is bright, very hard wearing and the easiest finish to match with existing fixtures. Brushed and antique brass finishes give a warm, vintage look; a single hole antique brass bathroom faucet suits traditional vanities and furniture-style cabinets. Gold reads more polished and glamorous; for the widest choice in that tone, browse our gold bathroom faucets. Matte black is the most graphic choice and suits modern rooms; see more in our black bathroom faucets. A few titles also mention spot-resistant brushed nickel, which hides water marks well.
Single Lever vs Two Handles
A single hole single handle bathroom faucet is quick to use with one hand and easy to set at a steady temperature. Two-handle faucets take up more deck space and need more holes, but give finer separate control of hot and cold, and many people prefer their traditional look. For a compact sink or a pared-back modern look, one lever is the practical pick.

Installing a Single Hole Bathroom Faucet
- Shut off the hot and cold valves under the sink and open the old faucet to drain the lines.
- Disconnect the supply lines and the drain linkage, then remove the old faucet and clean the deck.
- Thread the supply hoses onto the new faucet, set the gasket or deck plate, and feed the hoses through the hole.
- Tighten the mounting nut from below, keeping the spout aligned with the bowl.
- Connect the hoses to the valves, install the drain if included, and run water for a minute to flush the lines before fitting the aerator.

Single Hole Bathroom Faucets FAQ
Can I put a single hole faucet on a three-hole sink?
Yes, if the outer holes are 4 inches apart. Use a deck plate (escutcheon) that covers both outer holes. For holes spaced 8 inches or more, a widespread faucet is a better choice.
Is a single hole sink faucet good for a vessel sink?
Only if it is a tall vessel model. Standard-height faucets will not clear the rim of a raised bowl. Measure the bowl height before ordering.
Do these faucets come with a drain?
Some include a pop-up or push drain and some do not. Check the listing details, and make sure the drain style suits a sink with or without an overflow hole.
How do I stop a waterfall faucet from splashing?
Turn the lever only part way, since waterfall spouts release a lot of water at full flow. A deeper basin and a spout that lands near the bowl center also reduce splashing.
What flow rate should a bathroom faucet have?
Federal rules cap bathroom faucets at 2.2 gallons per minute, and water-saving models run around 1.5 gallons per minute or less. Reduced flow rates still feel comfortable for hand washing.
