Overview
Single-handle faucets control both temperature and flow with one lever or knob. Twist or lift to turn on, swing left for hot, right for cold.

Single-handle faucets mount through one hole and work with deck plates on multi-hole sinks.

Top Brands for Single-Handle Faucets
Sizing & Selection
Single-hole faucets need a 1-3/8 inch mounting hole. Deck plates cover 3-hole (4-inch spread) or 4-hole configurations. For bathroom sinks, check whether you need a centerset (4-inch) or single-hole. Measure spout height and reach to ensure the water stream hits the center of the basin.
Installation
Feed supply lines and mounting hardware through the sink hole. Secure with a mounting nut from below (basin wrench needed). Connect hot (left) and cold (right) supply lines to shut-off valves. Hand-tight plus quarter turn. Remove the aerator, flush debris, then reinstall. 30-60 minutes for most installations.
Maintenance
- Replace the cartridge when dripping starts -- -25 and 15 minutes of work.
- Clean the aerator every 6-12 months by unscrewing and rinsing sediment from the screen.
- Wipe the handle and base dry regularly. Water pooling at the base causes mineral buildup and eventual corrosion.
- Tighten the handle set screw if the handle feels loose -- usually an Allen screw under a cap.
Buying Tips
- Ceramic disc cartridges are the gold standard -- smoother operation and longer life than ball valves.
- Brass or zinc alloy bodies outlast plastic. Lift the faucet in the store -- heavier is better.
- Matching accessories (soap dispenser, side sprayer) from the same brand ensure finish consistency.
- Widespread bathroom faucets look better than centerset on larger vanities, but single-handle centerset is fine for smaller sinks.
