AfterHow Much Does Bathroom Vanity Installation Cost in Orange County?
Bathroom vanity installation in Orange County typically costs $800 to $3,000 in 2026, with most mid-range single-sink vanities landing between $1,200 and $2,200 including labor, basic plumbing hookup, and haul-away of the old unit. The final number depends on vanity size, whether you’re replacing a single or double sink, plumbing modifications, and the condition of the wall behind the old cabinet. A basic swap where the existing plumbing lines align with the new vanity runs toward the lower end; a job requiring new shut-off valves, drain relocation, or drywall repair after water damage pushes toward the top.
We give every homeowner a written price before any work starts, so the number you approve on day one is the number on the invoice. No verbal ballpark that changes when the crew arrives. That’s how we’ve operated under The Kingswell Way since 2004.
Key Takeaways
- Most vanity installations in Orange County cost $800 – $3,000 total in 2026.
- Labor makes up roughly 40 – 55% of the job; the vanity itself covers the rest.
- Double-sink vanities run $1,500 – $3,000+ depending on width and countertop material.
- Plumbing modifications are the biggest cost-driver: moving a drain line or supply line can add $300 – $900.
- Every Penhallow Remodeling job includes a 365-Day Done Right Promise in writing, at no extra charge.
Bathroom Vanity Installation Cost Breakdown (2026)
Here’s how a typical vanity installation project in Orange County breaks down by line item. These ranges reflect what we see across Costa Mesa, Irvine, Fullerton, Huntington Beach, and the rest of the county in 2026.
| Project Component | Typical Cost Range (Orange County, 2026) |
|---|---|
| Stock vanity (36 – 48″, single sink, basic finish) | $300 – $900 |
| Semi-custom vanity (48 – 60″, soft-close drawers, solid wood) | $1,000 – $2,400 |
| Custom-built vanity (any size, any finish) | $2,500 – $5,000+ |
| Labor: removal, installation, basic hookup | $400 – $900 |
| Plumbing modifications (relocate drain, new shut-offs, re-pipe supply lines) | $300 – $900 |
| Faucet and drain assembly | $100 – $500 |
| Countertop (cultured marble or quartz top) | $150 – $1,200 |
| Drywall or backer board repair behind old vanity | $150 – $500 |
| Haul-away and disposal of old vanity | $50 – $150 |
| Permit (required in most Orange County cities when plumbing is moved) | $80 – $250 |
The single biggest variable is whether the existing supply lines and drain line up with the new vanity. In older Orange County homes, especially those built in the 1960s and 1970s in neighborhoods like Westpark in Irvine or Old Towne Orange, drain lines often sit at heights and offsets that don’t match today’s vanities. That’s when a straightforward swap becomes a plumbing job. Most of the cost range above comes down to that one factor.
What Affects Bathroom Vanity Installation Pricing in Orange County
Here’s what moves the needle in Orange County specifically. These aren’t generic factors, they’re the ones we deal with on job sites every week.
- Vanity width and sink count. A 30-inch single-sink vanity is the least expensive to install because it drops into most existing plumbing rough-ins. A 60-inch double-sink vanity usually requires cutting into the wall to widen rough-in spacing, which adds $250 – $600 in labor.
- Plumbing condition behind the old vanity. In Anaheim, Garden Grove, and Santa Ana, we regularly open walls and find corroded galvanized supply lines or a p-trap that’s been slowly leaking for a decade. If we’re replacing those lines, the job costs more because we’re doing plumbing work, not just cosmetic work.
- Wall and floor condition after demo. Removing an old vanity frequently exposes water damage along the baseplate or moisture-stained drywall from a slow faucet or drain leak. That wall has to be repaired before the new vanity goes in, and that adds $150 – $500 depending on how far the damage runs.
- Countertop material. A cultured marble top with an integrated bowl is the most affordable. Quartz tops from brands like Cambria or Caesarstone run higher, but they carry their own lifetime warranty alongside ours, which matters when the vanity is in a bathroom that gets daily use.
- City permit requirements. If the drain location moves, most Orange County cities, including Newport Beach, Costa Mesa, and Huntington Beach, require a plumbing permit. It’s not expensive, $80 to $250 depending on the city, but it has to be pulled. We handle that paperwork as part of the job.
- Upstairs installation logistics. In a two-story Mission Viejo or Laguna Niguel home, a 72-inch double vanity has to be carried up a flight of stairs and around a landing. That’s labor time. It’s straightforward but it’s not free, and an honest estimate accounts for it.
Is It Cheaper to Repair or Replace a Bathroom Vanity?
If the cabinet box is structurally sound and the only issue is a worn finish, a chipped countertop, or a loose door hinge, repair almost always costs less than replacement. Cabinet refinishing in Orange County runs $400 – $1,200, and replacing just the countertop runs $300 – $900 installed. But if the cabinet has water-swollen particleboard, a cracked face frame, or the drawers jam every morning, you’ll spend more propping it up than replacing it. Here’s the honest rule we give homeowners in Tustin and Yorba Linda: if repair cost is past 60% of replacement cost, replace it. You get a warranty that actually means something, and you’re not paying to save a cabinet that’s already failing.
Our 365-Day Done Right Promise covers every repair and every installation we do. If the drawer slide fails or the plumbing leaks inside that first year, we come back and fix it at no charge. That promise is in writing on every project, including the smaller repair jobs.
Can You Install a Bathroom Vanity the Same Day?
Yes, in most cases. A single-sink vanity swap where the plumbing already aligns takes our crew 3 to 5 hours, from removing the old cabinet through caulking the new backsplash. A double-sink vanity with plumbing modifications takes 6 to 9 hours, which usually means one full day on site. If drywall repair or water damage remediation is involved, that part of the job has to dry before we set the new vanity, which can extend the project by a day or two.
We give every homeowner a defined arrival window before the job starts. Not “sometime Thursday.” The Kingswell Way was built on that: say the price before the work, show up in the window we gave, leave the place cleaner than we found it. Our technicians are background-checked and arrive in uniform, so you know exactly who’s walking into your home.
How Much Does a Bathroom Vanity Cost Without Installation in Orange County?
If you’re buying the vanity yourself, here’s what Orange County showrooms and home centers charge in 2026:
- Stock vanity (30 – 48 inches, particleboard box, laminate top): $180 – $750
- Mid-grade (36 – 60 inches, plywood box, soft-close doors): $700 – $1,800
- Semi-custom (any width, solid hardwood, dovetail drawers): $1,500 – $3,500
- Fully custom (built to your dimensions, any species): $2,800 – $6,000+
One thing we see in Laguna Hills and Aliso Viejo almost weekly: a homeowner buys a 60-inch vanity at a big-box store, gets it home, and the drain rough-in doesn’t align. Now they’re paying us to open the wall and re-plumb, and the “deal” on the vanity evaporated. If you’re sourcing the vanity yourself, measure the rough-in before you buy, or call us first. Our bathroom vanity installation service includes a measurement check before we order anything, so mistakes like that never happen on our watch.
Labor Cost for Bathroom Vanity Installation in Orange County
Labor alone for a vanity installation in Orange County runs $400 – $900 for a standard single-sink swap and $700 – $1,400 for a double-sink vanity with plumbing modifications. That labor includes removing the old vanity, assembling the new cabinet, leveling it, reconnecting supply and drain lines, sealing the backsplash, and hauling the old unit away. A licensed plumber in Orange County bills $80 – $150 per hour; a general contractor managing the full job typically charges a project rate rather than hourly, which is what we do.
We’re a general contractor, not a plumbing subcontractor passing through. That means one team handles the removal, the plumbing, the cabinet setting, and the finish work, and one written guarantee covers the whole job. If something fails, there’s no finger-pointing between trades. Call (424) 541-1701 and we’ll give you a written price for the whole thing.
Bathroom Vanity Installation vs. Full Bathroom Remodel: Where’s the Line?
If all you’re replacing is the vanity, the faucet, and the countertop, you’re in vanity-installation territory: $800 – $3,000. If you’re also swapping the flooring, replacing the shower surround, moving a wall, or relocating the toilet, that’s a bathroom remodel, which runs $9,000 – $28,000 in Orange County. A small bathroom remodel in a condo or townhome runs $5,000 – $12,000. The line matters because it changes the permit, the timeline, and the crew.
If you’re not sure which side of the line you’re on, we’ll tell you over the phone or during a free walkthrough. We don’t upsell remodels. If a vanity swap is all you need, that’s what we quote. Our home remodel team handles both, but we’ll never talk you into a $20,000 project when a $1,500 one solves the problem.
How to Save on Bathroom Vanity Installation
Saving money on a vanity installation is about lining up the right variables, not finding the cheapest contractor. Here’s what actually works in Orange County.
- Keep the vanity in the same footprint. If the new vanity is the same width and depth as the old one, and the sink is on the same side, you skip plumbing modifications entirely. That’s $300 – $900 saved before you start.
- Choose a stock-size vanity with a standard top. A 36 or 48-inch vanity with a cultured marble top drops into most rough-ins and costs less for both materials and labor.
- Replace both the vanity and the faucet at the same time. If the faucet is original to the house, it’s going to fail soon anyway. Replacing it while the vanity is out costs less than paying for a separate plumbing service call six months later.
- Buy the vanity from a supplier who measures. We order from brands like KraftMaid and Wellborn, which means the cabinet arrives in the dimensions we specified, and we don’t burn labor hours making a misfit work. A mis-ordered vanity that has to be returned and reordered is the most common avoidable cost we see.
- Get a written price up front. Every Penhallow Remodeling Orange County project starts with a written number, not a range. You’ll know exactly what the job costs before we start, and that number doesn’t move unless you change the scope. Call (424) 541-1701 for a free estimate anytime.
FAQs – Bathroom Vanity Installation Cost
How much should I pay to have a bathroom vanity installed?
In Orange County, expect to pay $800 – $3,000 total for a standard vanity installation in 2026. That includes the vanity, faucet hookup, drain connection, and haul-away of the old unit. A simple 36-inch single-sink swap starts around $800; a 60-inch double vanity with new plumbing runs toward $3,000. Call (424) 541-1701 for a written quote on your specific bathroom.
What does a bathroom vanity cost per linear foot?
A stock or mid-grade vanity runs $20 – $50 per linear foot for the cabinet alone. Semi-custom and custom vanities in Orange County run $60 – $150 per linear foot depending on wood species, drawer construction, and finish. A standard 48-inch vanity therefore costs roughly $960 – $2,400 for a mid-grade to semi-custom cabinet before installation labor.
Does a bathroom vanity installation require a permit in Orange County?
Only if plumbing drain lines or supply lines move. Swapping a vanity in the same footprint with existing plumbing positions does not require a permit in most Orange County cities. If the drain rough-in changes, cities like Costa Mesa, Newport Beach, and Irvine typically require a plumbing permit costing $80 – $250. We pull the permit when it’s needed and include that cost in your written price.
Is it cheaper to install a vanity or replace the whole bathroom?
A vanity installation costs $800 – $3,000; a full bathroom remodel in Orange County runs $9,000 – $28,000. If the rest of the bathroom, the shower, the floor, the lighting, is in decent shape, replacing only the vanity is obviously cheaper. If the floors are failing and the shower tile is cracking, doing everything at once saves you paying for two mobilizations and two sets of permits later.
How long does bathroom vanity installation take?
Most single-sink vanity installations take 3 – 5 hours from removal through final caulking. A double-sink vanity with plumbing modifications takes one full day. If water damage repair or drywall replacement is needed behind the old vanity, add a day or two for drying time. We give every customer a defined arrival window before the job starts and a written schedule before we begin.
Can you install a vanity I bought myself?
Yes, with one important caveat: we’ll measure your rough-in and confirm the vanity will actually fit before we start the job. If the vanity you bought doesn’t align with the existing plumbing, we’ll tell you during the free estimate so you can exchange it before we’re on site. Our written price covers installation labor and hookup, and the 365-Day Done Right Promise covers our work.
Why Orange County Homeowners Choose Penhallow Remodeling
Trevor Nash runs Penhallow Remodeling Orange County, and he’s built the team around a specific observation: most homeowners in this area aren’t looking for the cheapest bid. They’re looking for a contractor who answers the phone, shows up when they said they would, gives a real price instead of a moving target, and stands behind the work after the crew leaves. That’s not a marketing pitch, it’s the entire operating system.

If the vanity door comes loose, the drain leaks, or the caulk line fails inside that year, we come back and fix it at no charge. No re-inspection fee, no service call charge, no argument.
We install vanities with hardware from Kohler, Moen, and Delta, and cabinet lines from KraftMaid and Wellborn. The products behind the work are as solid as the guarantee covering them.
