A centerset faucet combines the spout and handles on a single 4-inch base, while a widespread faucet uses three separate pieces spaced 8 inches apart. Widespread looks more upscale; centerset is easier to install.
When to choose centerset
Centerset is ideal for smaller bathrooms and standard three-hole sinks drilled 4 inches apart. It is compact, affordable, and quick to fit.
When to choose widespread
Widespread suits larger vanities and gives a custom, high-end look. The separate handles also make it easier to fine-tune hot and cold.
