From underneath the sink, install the mounting hardware onto the faucet's threaded shank in the following order: stabilization ring, rubber gasket, and then the metal washer. Thread the basin nut onto the shank. Before tightening the nut completely, insert the two basin screws into the nut. Hand-tighten the basin nut, then use a basin wrench to make it snug. Finally, use a Phillips screwdriver to tighten the two screws evenly, which will firmly secure the faucet in place.

Goal: Fasten faucet to the sink

  • Insert the basin screws into the basin nut before threading the nut onto the faucet. This makes them easier to access and tighten.

FAQs

How long should a beginner expect to spend replacing a two-handle bathroom faucet and drain?

For a beginner, this project typically takes 2-4 hours, assuming no major complications like seized nuts. The difficulty is rated as 'beginner' because it involves straightforward steps, but patience is key, especially when working in tight under-sink spaces.

Are there any essential tools I might not already have that are crucial for this faucet replacement?

Yes, a basin wrench (like the Husky 1-1/2 in. Quick-Release Telescoping Basin Wrench) is invaluable for reaching and loosening nuts in tight spaces under the sink. You'll also want a quality adjustable wrench, tongue and groove pliers (Channellock 442), and a reliable flashlight (Panther Vision FLATEYE F-310) for visibility.

What are the critical preparation steps and safety precautions before I start disconnecting anything?

Always begin by shutting off both the hot and cold water supply valves under the sink, then turn on the old faucet to relieve pressure and drain residual water. Have a bucket (Unger 6 Gal. Heavy-Duty Plastic Bucket) and a rag (Better Trends Hugo Collection Bath Rug) ready to catch any spills and protect your cabinetry.

What are the most common reasons for leaks after installing a new faucet or drain, and how can I prevent them?

Leaks often occur from loose supply line connections or improper sealing of the drain assembly. Ensure all connections are hand-tightened, then given an additional quarter to half turn with a wrench. For the drain, properly apply plumber's putty (Oatey 14 oz. Plumber's Putty) around the flange before seating it.

Next we're going underneath the sink. With the sink, the mounting kit is going to go in this order. Stabilization ring, gasket, washer, bass and nut, bass and screws. Put your bass and screws on before you put your bass and nut on. Since it's a little tight underneath the sink to get a camera there, I'm going to show how this is mounted with the sink mixer in my hand. First, stabilization ring goes on with the circle side down, followed by the gasket, then our washer. I put the bass and screws into the bass and nut before the bass and nut goes on. As a bro tip, put the screws flush to the bass and nut, and that just threads on to the brass piece. When your bass and nut is tight, you'll use a bass and wrench to make it snug and then a Phillips driver to make it really tight.
