In this video
Take the new faucet assembly and carefully feed the attached hoses and wires down through the mounting hole in the countertop. Ensure the faucet base is seated correctly on the countertop surface. From underneath the sink, slide the plastic mounting bracket up over the hoses and onto the faucet's threaded shank. Follow this with the large brass mounting nut, threading it onto the shank by hand. Use the included plastic tightening tool to fully tighten the nut, securing the faucet assembly. Check the faucet's alignment from above to ensure it is straight. Finally, use a Phillips head screwdriver to tighten the two screws on the mounting bracket, which will clamp it against the underside of the counter and prevent the faucet from rotating.
Goal: Secure the new faucet to the countertop
- Have someone hold the faucet in the correct position from above while you tighten it from below to ensure proper alignment.

FAQs
What should I do if I can't locate the shut-off valves for my bathtub, or if they don't work?
If individual tub shut-off valves are missing or malfunctioning, you'll need to turn off the main water supply to your entire house. The main valve is usually located where the water line enters your home, often in a basement, utility closet, or near the water heater. After turning off the main supply, open a lower-level faucet to drain water from the pipes before proceeding with the tub faucet replacement.
Beyond the adjustable wrench and screwdriver, are there any other tools that might make this tub faucet replacement project easier?
While the basic tools will suffice, a deep socket set (specifically for valve stems) or a basin wrench can be incredibly helpful for accessing and loosening nuts in tight spaces. You might also want a utility knife or scraper for removing old caulk or plumber's putty, and a flashlight for better visibility under the tub.
As a beginner, how much time should I allocate for replacing my tub faucet, and what's the typical cost for a new one?
For a beginner, this project typically takes between 1 to 3 hours, depending on how easily the old components come apart. The cost of a new tub faucet can vary widely, from around $50 for a basic model to several hundred dollars for high-end designer fixtures, so choose one that fits your budget and style.
What are the most common mistakes people make when replacing a tub faucet, and how can I avoid leaks after installation?
Common mistakes include not completely turning off the water, overtightening connections, or failing to use enough plumber's putty or thread sealant where required. To prevent leaks, ensure all connections are snug but not overtightened, apply plumber's putty consistently under the new faucet base, and always test for leaks thoroughly before closing up any access panels.
