Quick Answer
A single-hole bathroom faucet mounts through one hole and usually has one handle. A centerset faucet mounts through three holes at 4-inch spacing and combines the spout and two handles on one base.
Hole Count and Layout
Single-hole needs one opening. Centerset needs three openings with 4-inch spacing between the outer holes.
Handle Options
Single-hole faucets usually have one handle but can have two handles on a shared base. Centerset faucets have two handles with a center spout.
Look and Installation
Single-hole reads modern and is easier to install. Centerset is a classic, budget-friendly look that is also straightforward to install.
Which Should You Pick?
Choose single-hole for a clean modern vanity. Choose centerset if you have a standard three-hole sink with 4-inch spacing and want a traditional two-handle design.
