How Long Does It Take to Replace a Faucet?

Quick Answer

Replacing a faucet takes 30–90 minutes in most cases. A simple kitchen or bathroom faucet swap where the new faucet matches the existing hole configuration takes about 30–45 minutes. Corroded fittings, hard-to-reach connections, or switching to a different faucet type can push the job to 90 minutes or longer.

Time by Faucet Type and Location

Faucet Type	Location	Time Estimate	Difficulty
Single-handle bathroom	Bathroom sink	20–40 minutes	Easy
Center-set bathroom (two handles)	Bathroom sink	30–50 minutes	Easy
Widespread bathroom (three pieces)	Bathroom sink	45–75 minutes	Moderate
Single-handle kitchen	Kitchen sink	30–60 minutes	Easy–Moderate
Kitchen with pull-down sprayer	Kitchen sink	40–70 minutes	Moderate
Kitchen with separate sprayer	Kitchen sink	45–90 minutes	Moderate
Pot filler	Above stove	60–120 minutes	Difficult
Bathtub faucet	Tub	60–120 minutes	Difficult

Kitchen vs. Bathroom Comparison

Factor	Kitchen Faucet	Bathroom Faucet
Average time	45–75 minutes	25–50 minutes
Access difficulty	Harder (deep cabinet)	Easier (open pedestal or vanity)
Water line connections	Often larger, more complex	Usually straightforward
Sprayer/hose	Common, adds time	Rare
Garbage disposal connection	May interfere with access	N/A

Kitchen faucets generally take longer because reaching the mounting nuts under a kitchen sink requires working in a cramped space around the garbage disposal, dishwasher hose, and drain pipes.

Step-by-Step Time Breakdown

Step	Time
Turn off water supply valves	2–3 minutes
Disconnect supply lines from old faucet	5–10 minutes
Remove old faucet mounting nuts	5–15 minutes
Lift out old faucet and clean surface	5–10 minutes
Apply plumber's putty or gasket to new faucet	3–5 minutes
Set new faucet and hand-tighten mounting nuts	5–10 minutes
Connect supply lines	5–10 minutes
Turn on water and check for leaks	5 minutes
Total	35–70 minutes

Common Complications and Added Time

Complication	Added Time	Solution
Corroded mounting nuts	15–30 minutes	Basin wrench, penetrating oil, or hacksaw
Seized supply line connections	10–20 minutes	Penetrating oil, adjustable wrench
Different hole configuration	30–60 minutes	Deck plate cover or drilling new holes
No shut-off valves under sink	20–40 minutes	Install new shut-off valves
Corroded supply lines	15–25 minutes	Replace with braided stainless lines
Leaks after installation	10–20 minutes	Re-tighten or re-seat connections

The single most common delay is corroded mounting nuts on the old faucet. A basin wrench is essential for this job — it is specifically designed to reach nuts in the tight space behind a sink. Applying penetrating oil (such as PB Blaster) and waiting 10–15 minutes often saves significant frustration.

Tools Required

• Basin wrench (essential for under-sink nuts)
• Adjustable wrench
• Channel-lock pliers
• Bucket and towels
• Plumber's putty or silicone
• Flashlight or headlamp
• Penetrating oil (for stubborn connections)

When to Call a Plumber

Faucet replacement is one of the most accessible plumbing DIY projects. However, calling a professional is recommended when shut-off valves need to be installed, when switching from a two-handle to single-handle configuration requires modifying the sink or countertop, or when supply lines show signs of corrosion that could lead to a leak behind the wall. A plumber typically charges $150–$350 for a faucet installation and completes the job in 30–60 minutes.
