The answer to 'types of faucet installation' is there are several common types of faucet installation, including deck-mounted, wall-mounted, and vessel-style faucets. Deck-mounted faucets are the most common, installed directly into the sink or countertop. Wall-mounted faucets are attached to the wall above the sink, while vessel-style faucets are designed for sinks that sit above the countertop.
The type of faucet installation you choose will depend on the configuration of your sink and countertop, as well as your personal style preferences. Deck-mounted faucets are generally the easiest to install, while wall-mounted and vessel-style faucets may require more complex plumbing work. It's important to carefully measure your sink and countertop before selecting a faucet to ensure a proper fit.
