A basin wrench (like the Husky 16PL0127) is indispensable for reaching and loosening mounting nuts under the sink. An adjustable wrench, a headlamp or flashlight (like the Energizer Vision HD Pro), and a putty knife are also critical for an easier, more efficient installation. Don't forget a bucket and towels for spills.

Always begin by shutting off both hot and cold water supply lines underneath the sink. Turn on the old faucet to drain any residual water and depressurize the lines. Place a bucket (like the Unger 6 Gal. Heavy-Duty Plastic Bucket) and towels under the work area to catch drips and spills, and consider wearing safety glasses.

For a beginner, this project is rated as 'beginner' difficulty but can still take 1 to 3 hours, especially if you encounter stubborn nuts or need extra time for cleaning. Patience is key, and taking your time to ensure proper connections will prevent leaks later. The cost typically involves just the new faucet and some basic supplies like Teflon tape.

A common mistake is forgetting to use Teflon tape on threaded pipe connections, or overtightening/undertightening supply lines. Always apply Teflon tape clockwise on male threads, hand-tighten connections first, then give an extra quarter to half turn with a wrench. Thoroughly check all connections for leaks after turning the water back on, and be prepared to tighten slightly if needed.
