Typical Duration
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.
