Here’s the fun part: you probably already own most of this stuff. A bucket (for catching that surprise water), slip-joint pliers (or even your bare hands if you’re brave), and a flathead screwdriver are your main squad.
Oh, and plumber’s putty—it’s like modeling clay for grown-ups that stops leaks. Don’t skip it, or your sink will cry sad drips under the cabinet.
Also, grab some Teflon tape. It’s the duct tape of the plumbing world, but for threads instead of everything else. Trust me, you’ll feel like a wizard wrapping it around.
