There are many types of 4 inches lavatory faucets on the market. These faucets are usually four inches long from handle to handle. The faucet's width varies depending on the manufacturer. You can choose between single-handle faucets and dual-handle faucets. Some faucets also feature an escutcheon plate.

One type of four inches lavatory faucet is the centerset faucet. This faucet type is easy to install and requires only three holes on the sink or mounting surface. The faucet also requires only one base and is available in single-lever versions. The deckplate will cover all three holes and the hot and cold water inlet tubes will be installed through the middle hole.

For bathrooms with small sinks, 4 inches lavatory faucets are best suited. For larger bathrooms, an 8-inch faucet would work perfectly. Nevertheless, some sinks may be too small to accommodate a widespread faucet. You can also look for 4-inch centerset faucets or mini widespread faucets.
