WALL-MOUNT - Wall-mounted models have become increasingly popular, even though they are the most difficult to install of all lavatory faucets. Moving the faucet off the counter reduces clutter, simplifies cleanup, and addresses the height required by above-counter basins.

SINGLE-HOLE - Installation of the sleek single-hole faucet is relatively easy, as is maintenance. With just one part piercing the countertop or sink, there are fewer details to collect soap and soil.

WIDESPREAD - The separate valves on a widespread faucet can be placed 8 to 16 inches apart, requiring a three-hole installation. Most high-end faucets are widespread.

CENTER-SET - The least expensive lavatory faucets fall into this category — the valves and spout are joined in a single unit. A two-hole center-set unit like this is the simplest faucet to install.

MINI-WIDESPREAD - Bridging the gap between center-set and cleaner-looking widespread configurations, mini-widespread faucets are separate visually, and the valves are just 4 inches apart.
