The answer to 'which is better faucet installation or' is that faucet installation is generally better than faucet replacement for most homeowners. Faucet installation allows you to completely upgrade your faucet and plumbing hardware, providing more customization options and a higher-quality finished product. It typically requires more skill and labor, but the end result is a more seamless, long-lasting faucet setup.
In contrast, faucet replacement is a simpler, more DIY-friendly option that involves swapping out an existing faucet with a new one. This is a good choice if your current faucet is outdated or damaged, but you're happy with the existing plumbing configuration. Replacement is generally faster and more affordable, but doesn't allow for as much customization or improvement to the overall plumbing.
