Choosing a bathroom sink faucet is not only about finish and style. The number of mounting holes in your vanity determines which faucet will fit, how it will look, and how easy it will be to install. Two common choices are a 3-hole bathroom sink faucet and a single-hole faucet.
What Is a 3-Hole Bathroom Sink Faucet?
A 3-hole bathroom sink faucet uses separate openings for the spout, hot-water handle, and cold-water handle. The handles may sit close to the spout in a centerset layout or farther apart in a widespread layout.
This configuration provides independent hot and cold control and creates a balanced appearance for medium and large vanities.
What Is a Single-Hole Bathroom Faucet?
A single-hole faucet combines the spout and control handle into one compact fixture. It is popular for small sinks, modern bathrooms, and minimalist interiors.
3-Hole vs Single-Hole: Key Differences
Installation
Check the existing hole pattern before buying. If your sink has three holes, a 3-hole faucet is usually the most direct replacement. A single-hole faucet may require a deck plate to cover unused openings.
Temperature Control
A double-handle faucet lets you adjust hot and cold water separately. A single-handle faucet is faster to operate with one hand.
Cleaning and Style
Single-hole models have fewer gaps to wipe around. Three-hole faucets suit classic, transitional, and statement vanities. Matte black creates strong contrast against white stone, porcelain, and light wood.
How to Measure Before You Buy
- Count the mounting holes under or behind the sink.
- Measure between the centers of the two outer holes.
- Check the spout reach so water lands near the basin center.
- Confirm clearance for handles and the backsplash.
- Review supply connections and countertop thickness.
Widespread faucets commonly use 8-inch outer-hole spacing, but always measure your actual vanity.
Which Should You Choose?
Choose a 3-hole bathroom sink faucet when your vanity has three openings, you prefer separate temperature controls, or you want a substantial focal point. Choose a single-hole faucet when space is tight, easy cleaning is the priority, or you prefer a minimalist look.
