How to Replace a Deck-Mount Garden Tub Faucet · Step 1 of 9
In this video
Gain access to the plumbing behind the tub, typically through an access panel. Carefully disconnect the hot, cold, and shower riser water lines from the back of the old faucet. These connections use swivel adapters that should be unscrewed by hand. Be gentle, as old CPVC pipe is known to be brittle and can crack easily. After the water lines are free, move to the front of the tub. The faucet is held in place by large plastic nuts on the threaded shanks; unscrew these. Once the nuts are off, you can pull the entire old faucet assembly away from the tub surround.
Goal: Remove the Old Faucet Assembly
- Apply steady, even pressure when working with old CPVC pipes to avoid snapping them.

FAQs
Is this project truly intermediate, and what are the main challenges I might face?
Yes, this project is rated intermediate due to the tight spaces often found under garden tubs, potential corrosion on old fasteners, and the critical need for watertight seals. Expect to spend significant time gaining access, maneuvering tools, and meticulously checking for leaks. Patience and preparation are key.
My old faucet seems stuck or corroded to the deck. What's the best way to loosen it?
Corrosion is common. Apply a penetrating oil like KROIL directly to the nuts under the tub deck and allow it to soak for at least 30 minutes, or even an hour. Use a basin wrench for extra leverage in tight spots, as it's designed for these hard-to-reach fittings.
What are the most common reasons for leaks after installing a new deck-mount faucet, and how can I prevent them?
Leaks typically occur from improperly sealed connections or loose fittings. Always apply 2-3 wraps of Teflon tape clockwise to all threaded pipe connections before tightening. For the faucet body, ensure you use a generous but neat amount of plumber's putty around the base to create a watertight seal against the tub deck.
My tub's access panel seems too small or is difficult to open. What should I do if I can't reach the plumbing easily?
Gaining proper access is crucial and sometimes the most challenging part. Use a headlamp for visibility and consider temporarily removing any surrounding trim or cabinet components if necessary. If space is extremely limited, you might need to carefully enlarge the access opening, ensuring it can be neatly covered afterward.
