Kitchen faucet installation cost in Los Angeles typically runs $150–$450, with most straightforward swaps landing between $180 and $320. The faucet itself is only part of the bill — what actually moves the price is whether your existing shutoff valves still turn, how many holes are already in your countertop or sink, and whether the new faucet needs a sprayer or soap dispenser hookup. A clean swap on working valves is the cheap end. Corroded shutoffs, a mismatched hole count, or supply lines that have to be replaced push it toward the top.
This guide breaks down pricing by scenario, the factors that actually drive cost up or down, faucet types, when the job crosses into plumbing territory, and the mistakes that turn a one-visit job into two.
Kitchen Faucet Installation Cost by Scenario
| Scenario | Typical Cost | Why |
|---|---|---|
| Like-for-like swap (same hole count, working shutoffs) | $150–$250 | Disconnect old faucet, connect new supply lines, seal and test |
| Swap with a different hole configuration | $220–$350 | May need a deck plate, escutcheon, or sink modification |
| New faucet with corroded or seized shutoff valves | $280–$450+ | Valves often need replacing before the faucet can go in — sometimes a plumber call |
| Pull-down or touchless faucet with new supply lines | $250–$400 | Heavier unit, weighted hose, sometimes a dedicated outlet for touchless power |
These ranges assume a standard under-sink kitchen setup with reasonable access. Tight cabinets, a garbage disposal in the way, or an integrated soap dispenser line add time on top of any bracket.
What Affects Kitchen Faucet Installation Cost
A handful of factors move the price on nearly every kitchen faucet job we quote.
1. Shutoff Valve Condition
This is the single biggest swing factor, and it’s invisible until we’re under the sink. Working shutoffs mean a quick, contained job. Valves that are seized, drip when turned, or won’t fully shut off water need replacing first — that’s extra parts and time, and sometimes means shutting off water to the whole house temporarily.
2. Faucet Type and Weight
A basic single-handle faucet installs faster than a heavy pull-down model with a weighted retraction hose or a touchless sensor faucet that needs battery access and sometimes an outlet nearby.
3. Hole Count and Deck Plate Fit
Sinks are drilled for one, two, or three holes. A single-hole faucet going into a three-hole sink needs a deck plate to cover the extra holes. A widespread three-piece faucet going into a single-hole sink usually isn’t possible without countertop or sink modification — worth checking before you buy.
4. Supply Line Length and Material
Braided stainless supply lines are the standard now and usually swap in cleanly. Older rigid or corroded lines sometimes need full replacement, which adds a small parts cost and a few extra minutes of work.
5. Sprayer and Soap Dispenser Hookups
A side sprayer or built-in soap dispenser means an extra hole to fill or connect. If you’re adding a feature your old faucet didn’t have, that’s additional hardware and hookup time.
6. Countertop and Sink Material
Granite, quartz, and stainless sinks are straightforward to work around. Older cast-iron or enameled sinks in pre-1960s LA homes can have tighter clearances or chipped mounting surfaces that need extra care.
Kitchen Faucet Types and How They Change the Price
| Type | Typical Install Time | Notes |
|---|---|---|
| Single-handle, single-hole | 30–60 min | Fastest, most common swap |
| Two-handle, three-hole | 45–75 min | More connection points, deck plate sometimes needed |
| Pull-down/pull-out sprayer | 45–90 min | Heavier, weighted hose routing takes extra care |
| Touchless/sensor | 60–100 min | Battery pack or transformer placement, sometimes an outlet |
| Commercial-style/pot-filler add-on | 75–120 min+ | Often needs its own shutoff and supply line — closer to a plumbing job |
Higher-end faucets aren’t necessarily harder to install — a well-packaged pull-down faucet with clear instructions can go in as fast as a basic model. The install time usually tracks the plumbing underneath, not the price tag on the box.
Single-Hole vs. Three-Hole vs. Widespread Installations
Most modern kitchen faucets are single-hole, with the handle and spout combined into one unit. Three-hole sinks (common in homes built before the 2000s) fit either a single-hole faucet with a deck plate, or a separate two-handle faucet. Widespread faucets — separate hot, cold, and spout pieces — need more spacing than most kitchen sinks provide and are far more common in bathrooms. If you’re replacing a faucet and buying a new one online, matching hole count to your existing sink saves a trip back to the store and avoids a surprise deck-plate charge.
Corroded Shutoff Valves: The Hidden Cost in Older LA Homes
Homes in Pasadena, Silver Lake, and other pre-1960s neighborhoods often still have the original shutoff valves under the kitchen sink. Decades of hard water and mineral buildup can seize a valve shut, or worse, cause it to keep dripping after it’s “closed.” We test both shutoffs before disconnecting anything. If a valve won’t hold, we’ll quote replacing it as part of the job — it’s routine handyman work, but it does add to the estimate you got based on the faucet alone.
When Kitchen Faucet Installation Becomes a Plumbing Job
Most kitchen faucet swaps stay squarely in handyman territory. Call a licensed plumber first if:
- Supply lines need to be rerouted through the wall or cabinet framing
- There’s an active leak in the main line feeding the sink, not just at the faucet connection
- You’re adding a pot filler or instant-hot dispenser that needs a new supply line run
- The sink itself is being replaced or the countertop is being cut for a new configuration
We’ll flag it upfront if a job crosses into plumbing scope — better to make one extra call than install a fix that doesn’t hold.
DIY vs. Hiring a Pro for Kitchen Faucet Installation
A straight swap — same hole count, working shutoffs, standard supply lines — is a doable weekend project for a confident DIYer with basic tools and a flashlight. Here’s where it’s worth calling a pro instead:
- Working in a cramped cabinet. Kitchen sink cabinets are often tighter than bathroom vanities, especially with a garbage disposal or filtration system already installed.
- Shutoff valves that won’t cooperate. A seized valve that gets forced can crack, turning a faucet swap into an emergency shutoff at the main.
- Mismatched hole configurations. Buying the wrong faucet type for your sink is one of the most common DIY mistakes we get called to fix.
- You want it done in one visit. A rushed under-sink connection is one of the more common sources of slow leaks that show up weeks later, not immediately.
If you’re not sure which category your job falls into, our general handyman services page covers what we handle — and we’ll tell you upfront if a job needs a specialist instead.
Common Mistakes That Drive Up Cost Later
- Buying a faucet that doesn’t match the hole count. Returning it or buying a deck plate after the fact costs more than checking beforehand.
- Over-tightening supply line connections. Too tight can crack a compression fitting; too loose causes slow drips at the joint. Either way, it’s a return trip.
- Skipping plumber’s putty or silicone under the base. A faucet base without proper sealant will eventually let water seep under the sink deck.
- Ignoring a slow drip after install. A small leak under the sink often gets worse before it gets noticed. Catching it in the first day, not the first month, saves cabinet floors.
How to Save Money on Kitchen Faucet Installation
- Check your hole count before buying. Matching a new faucet to your existing sink configuration avoids a deck-plate surcharge or a return trip to the store.
- Buy your own faucet if you have a preference. We’re happy to install a faucet you’ve already purchased — you pay for labor, not markup on the fixture.
- Bundle it with other kitchen fixes. If you’re also swapping a garbage disposal or fixing a cabinet, bundling saves a trip charge versus separate visits.
- Mention shutoff valve age when you book. If your home is older and you’re not sure the valves still work, flagging it upfront helps us quote accurately from the start.

Frequently Asked Questions
How long does kitchen faucet installation take?
A straight swap on working shutoff valves usually takes 30–75 minutes. A job that needs new shutoffs, a deck plate, or a touchless power hookup takes longer.
Can I install a kitchen faucet myself?
If your shutoff valves work and the new faucet matches your sink’s hole count, a straight swap is a doable DIY project for many homeowners. Seized valves or a mismatched hole configuration are where it’s worth calling a pro.
Why is my new kitchen faucet leaking at the base?
The most common cause is a missing or uneven bead of plumber’s putty or silicone under the base plate. It’s an easy fix for a pro, but frustrating to diagnose blind from on top of the counter.
Is faucet replacement cost different from installation cost?
They’re usually quoted together — “faucet replacement cost” typically means the same labor as installation, since replacing an old faucet is the most common reason for the job. The faucet itself (bought separately) is on top of labor.
Do I need a permit to install a kitchen faucet in Los Angeles?
A like-for-like swap is routine maintenance and doesn’t need a permit. Work that alters supply lines through walls or adds new plumbing runs can cross into permit territory — a licensed plumber will handle that if your project reaches that point.
What’s the difference between a pull-down and pull-out kitchen faucet?
Pull-down faucets have a spray head that pulls straight down out of a tall gooseneck spout. Pull-out faucets have a shorter spout with a head that pulls out toward you. Both install about the same way — the choice comes down to sink depth and personal preference.
