AfterHow Much Does Bathroom Vanity Installation Cost in Los Angeles?
Bathroom vanity installation in Los Angeles costs between $945 and $3,540, with most homeowners landing somewhere in the $1,400-$2,200 range depending on vanity size, plumbing complexity, and whether the existing substrate needs work before the new unit goes in. That range covers labor, basic materials, and standard connection to existing supply and drain lines – it does not include the vanity cabinet itself if you’re supplying your own, or tile work around the installation area.
Bathroom Vanity Installation Cost Breakdown (2026)
Below is how the cost typically stacks up across the main line items Rowan Construction Group prices before any work starts. Every figure reflects the Los Angeles market as of 2026 – labor rates here run higher than national averages because of prevailing wage pressure, permit processing fees, and the licensed-and-insured crew standard that protects your home.
| Line Item | Typical Range (LA Market) | Notes |
|---|---|---|
| Single vanity, standard swap (like-for-like) | $945 - $1,480 | Same footprint, no plumbing relocation, no tile work |
| Single vanity with minor plumbing adjustments | $1,250 - $2,100 | Supply line extensions, drain repositioning up to 6 inches |
| Double vanity installation | $1,650 - $2,800 | Two sinks, two drain connections; wider cabinet handling adds time |
| Vanity with new countertop and sink | $1,800 - $3,200 | Countertop supply and set, undermount sink mounting, silicone seal |
| Full vanity installation with backsplash tile | $2,400 - $3,540 | Tile demo, waterproof membrane, new tile set behind vanity area |
| Substrate repair or wall prep (if needed) | $180 - $540 additional | Drywall replacement with moisture-resistant board, mold remediation if minor |
| Permit (City of Los Angeles, plumbing work) | $180 - $390 additional | Required when drain or supply lines are relocated; pulled by Rowan |
The single biggest swing factor is plumbing. A straight swap – same vanity width, same drain location, no surprises behind the wall – sits at the low end. Once the drain or supply lines need to move, even by a few inches, you’re into a licensed plumber’s territory in Los Angeles, and that adds both labor time and permit cost. In older homes throughout Silver Lake, Echo Park, and Highland Park, we regularly open a wall for a vanity replacement and find galvanized pipe that’s 50-plus years old. Replacing a corroded section while the wall is already open is almost always worth doing; ignoring it means a second visit – and a second disruption – within a few years.
Vanity cabinet cost is separate. If you’re sourcing from Kohler, Toto, or a custom cabinet shop, budget $400-$2,500 on top of installation depending on size and finish. If you want Rowan to supply the unit, the quote will include the cabinet at trade pricing from our vetted supplier network – the same written price, same written scope, before anyone touches a tool.
What Affects Bathroom Vanity Installation Pricing in Los Angeles
- Vanity size and configuration. A 24-inch single-sink cabinet in a powder room moves faster and costs less than a 60-inch double-sink vanity in a primary bath. Larger units require two-person handling, longer countertop cuts, and two separate drain connections – each of which adds time.
- Plumbing relocation. Los Angeles building code requires a licensed plumber for any work that moves a drain or supply line, and those permits go through the Department of Building and Safety before the inspection. That’s appropriate and protects the homeowner – but it does add $180-$390 to the permit side and typically one additional trade visit.
- Wall and substrate condition. Bathrooms in homes built before the 1980s – and there are a lot of them in Los Feliz, Culver City, and Leimert Park – often have regular drywall behind the vanity instead of cement board or moisture-resistant gypsum. When we pull an old unit and find that, it needs to come out before the new vanity goes in, or you’ll be back in the same spot with water damage in three years.
- Countertop material. A cultured marble top costs $150-$320 for the material; a Cambria quartz slab cut to fit runs $480-$1,100 before installation. If you want undermount sink mounting in natural stone, the fabricator adds a polished cutout charge on top of that.
- Existing tile condition. If the floor tile runs under the current vanity, removing the old cabinet sometimes chips or lifts those tiles. In bathrooms with continuous tile floors – common in mid-century homes across Hancock Park and Brentwood – the written quote will note whether the vanity sits on top of tile or on subfloor, because that affects demolition cost and whether tile repair is needed afterward.
- Los Angeles labor market. Licensed, background-checked, insured crews in LA cost more per hour than in many other markets. That’s not a markup – it’s the cost of operating legally and carrying the insurance that protects your home. Quotes from unlicensed crews that undercut by 30% routinely create the substrate and plumbing problems that bring homeowners back to Rowan for a second installation.

AfterHow to Save on Bathroom Vanity Installation in Los Angeles
The biggest savings come before anyone shows up with tools. Here’s where the money is actually saved – or lost.
Choose a like-for-like swap when the layout works
If the existing vanity is the same width as the one you want and the plumbing lines up, a direct swap is the most straightforward job in bathroom renovation. You’re not paying for plumbing relocation, extra permit fees, or substrate repair beyond what’s necessary. Measure the existing vanity’s width, the distance from center drain to the wall, and the supply line stub-out locations before you shop. Bring those numbers to the Rowan estimate and you’ll get an accurate flat price right away.
Combine work when the wall is already open
If you’re planning a larger Bathroom Vanity Installation in Los Angeles as part of a bathroom update, combining it with light plumbing or tile work in the same visit reduces total labor cost compared to scheduling two separate jobs. The crew is already there; the wall is already open. Adding a shutoff valve upgrade or a new backsplash at the same time costs less than returning for a second mobilization.
Supply your own vanity cabinet
Rowan installs customer-supplied vanities. If you’ve already found the unit you want at a big-box store, a specialty plumbing showroom, or a cabinet shop, bring the specs to the estimate call. We’ll quote installation only, and you keep whatever margin you negotiated on the cabinet. The one thing worth confirming: make sure the unit ships fully assembled or note the assembly time, because flat-pack assembly on-site adds time to the installation quote.
Get a second opinion on any written estimate you already have
Rowan offers a Free Second Opinion on any written estimate. Bring a competitor’s quote and Grant Rowan’s team will review it line by line at no charge – no pressure, no obligation. It’s a straightforward way to confirm whether a price is reasonable for the scope, or whether something is missing from the scope that will show up later as a change order. Call (213) 652-7670 to set that up.
Don’t skip the substrate inspection
This sounds counterintuitive as a savings tip, but it’s the most common way homeowners overpay long-term. A vanity installed over damaged drywall or corroded pipe will need to come out again. Paying for a proper substrate assessment upfront – it’s part of every Rowan site visit – costs nothing extra and avoids a second full installation charge inside a few years.
Understand what’s in the permit
In the City of Los Angeles, a simple vanity swap with no plumbing changes often doesn’t require a permit. Once drain lines or supply lines are relocated, a plumbing permit is required by code. Some contractors skip the permit to keep the quote low – which saves you $200 today and creates a disclosure problem when you sell the house and the work shows up unpermitted on a buyer’s inspection. Rowan pulls the permits that are legally required and notes in the written scope which trades are permitted and which aren’t. That’s not optional; it’s Clause 1 of the Haven Standard in practice.
Bathroom Vanity Installation Cost vs. Full Bathroom Remodel: When Does It Make Sense to Go Further?
A vanity installation is a contained scope. But homeowners in Los Angeles frequently ask whether it makes sense to stop there or fold the vanity into a broader update.
A small bathroom remodel in Los Angeles costs $5,900-$14,160 and typically covers the vanity, toilet replacement, new tile, and updated fixtures. A full bathroom remodel runs $10,620-$33,040 and includes layout changes, a new tub or shower, and finish work throughout. If the vanity is the only thing that needs replacing and the rest of the bathroom is in solid shape, the $945-$3,540 installation is the right answer. If the tile is cracked, the shower pan is soft, or the floor has moisture damage, doing the vanity in isolation means you’ll be tearing it out again in two or three years when you address the bigger issues. Rowan’s site visit will document exactly what we find – photo record included as a standard deliverable – so you can make that decision with real information in front of you, not a gut feeling.
For homeowners considering a walk-in shower installation alongside the vanity work, that scope runs $5,310-$14,160 in Los Angeles depending on pan size and tile selection. Combining trades on a single mobilization is almost always more cost-efficient than scheduling sequentially.
What the Installation Process Looks Like
Written price before anything starts
Under Clause 1 of the Haven Standard, no work begins until you have a written flat price and a written scope in hand. That means the quote is not “approximately” or “starting at” – it’s the number. If site conditions change what the crew finds (unexpected pipe corrosion, for example), nothing changes until you’ve reviewed and signed a change order. That administrative step is the reason Rowan’s projects have finished within a few percent of the agreed price across 4,000-plus jobs since 2007.
Day-of-installation sequence
The crew arrives uniformed and background-checked. They photograph the existing conditions before touching anything – that photo record goes to you as a standard deliverable. Demolition of the old vanity typically takes 30-60 minutes. Substrate inspection follows; if the wall behind the old unit shows water staining or soft board, that’s documented and a change order is presented before repair work starts. The new vanity is set, leveled, and secured to wall studs. Supply lines are connected, the drain is set and sealed, and the countertop is siliconed in place. A full single-vanity swap usually runs 3-6 hours. Double vanity or a job with tile work behind it runs 6-10 hours.
365-Day Done Right Promise
Every vanity installation Rowan completes is covered by the 365-Day Done Right Promise. If it’s not done right – a slow drain connection, a countertop seal that didn’t hold, a cabinet door that wasn’t aligned – Rowan makes it right. That’s not a handshake; it’s backed by the Haven Standard, and the terms are on the website. The customer doesn’t need to remember a phone number or dig up a business card; the photo record and written scope from the original visit document exactly what was done and when.
Los Angeles Neighborhoods We Serve
Rowan Construction Group works throughout Los Angeles, including Silver Lake, Echo Park, Highland Park, Los Feliz, Hancock Park, Brentwood, Culver City, Leimert Park, West Adams, Koreatown, Mid-City, and the west side communities from Santa Monica to Playa Vista. Bathroom conditions vary noticeably by neighborhood and building era. Homes in Highland Park and Boyle Heights built in the 1920s and 1930s frequently have cast-iron drain stacks and original plaster walls behind the vanity – both of which affect installation time and substrate prep in ways that a flat rate without a site visit can’t account for. That’s exactly why the written price comes after a site visit, not before.
Homes in newer construction throughout Playa Vista and Marina del Rey tend to have PVC drain lines and cement board substrate already in place, which means installation is faster and the price typically sits in the lower third of the range. The site visit confirms which situation you’re in before the number is written down.
FAQs: Bathroom Vanity Installation Cost in Los Angeles
How much does bathroom vanity installation cost in Los Angeles?
Bathroom vanity installation in Los Angeles costs $945 to $3,540, with a typical single-vanity swap landing around $1,200-$1,800 when no plumbing relocation is needed. Double vanities and installations that include a new countertop and backsplash tile run toward the higher end of that range. Call (213) 652-7670 for a written flat-price estimate – it’s free and specific to your bathroom’s actual conditions.
Does vanity installation require a permit in Los Angeles?
A simple like-for-like vanity swap with no changes to the drain or supply lines typically does not require a permit in the City of Los Angeles. Any work that relocates plumbing – even moving a drain a few inches to accommodate a different vanity width – requires a licensed plumber and a plumbing permit through the Department of Building and Safety. Rowan pulls every required permit and notes in the written scope which work is permitted and which is not, so there’s no ambiguity when you sell the home.
How long does vanity installation take?
A standard single-vanity swap takes 3-6 hours from demo to cleanup. A double vanity or a job that includes new tile work behind the cabinet typically runs 6-10 hours. If substrate repair is needed – replacing water-damaged drywall with moisture-resistant cement board, for example – that adds 2-4 hours and is documented in a change order before work proceeds.
Can I supply my own vanity cabinet and just pay for installation?
Yes. Rowan installs customer-supplied vanities and the quote covers labor, connection to existing plumbing, and any substrate work that’s needed. The one thing to confirm before the installation date is that the unit’s drain and supply rough-in dimensions match your existing rough-in locations, or that you’ve accounted for the plumbing adjustment cost if they don’t. Bring the manufacturer’s spec sheet to the estimate visit and the written quote will reflect the actual scope.
Is it cheaper to install a vanity during a full bathroom remodel?
Usually, yes. When a vanity installation is part of a broader bathroom remodel in Los Angeles (which runs $10,620-$33,040), the per-item cost of individual scopes tends to drop because mobilization, permit fees, and demo are shared across multiple line items rather than dedicated to one. If you know the broader bathroom work is coming in the next year or two, it’s worth at least getting a comparison quote for the combined scope before committing to the vanity installation alone. Rowan can quote both scenarios at the same site visit so you have real numbers to compare.
What brands of vanities does Rowan install?
Rowan installs vanities from Kohler, Toto, KraftMaid, Wellborn, and most major plumbing and cabinetry brands, as well as custom cabinet shop units and big-box store cabinets. The installation process and warranty coverage are the same regardless of where the cabinet came from. What changes is the substrate assessment – some flat-pack units require additional on-site assembly time, and some custom cabinets need shimming or scribing to fit older walls that aren’t perfectly plumb. Both are documented before they affect the price.
