AfterHow Much Does Bathroom Vanity Installation Cost in Sherman Oaks?
Bathroom vanity installation in Sherman Oaks, CA typically costs between $800 and $3,000, depending on the vanity size, cabinet style, countertop material, and whether the plumbing needs to be relocated. Most single-vanity swaps in Sherman Oaks homes – including labor, a mid-range cabinet, and a new sink – land between $1,100 and $1,800. If you’re replacing a double vanity in a primary bathroom or upgrading to a stone countertop, expect to sit closer to the $2,000-$3,000 range.

Bathroom Vanity Installation Cost Breakdown (2026)
The table below reflects what Rowan Construction Group sees quoted and invoiced across Sherman Oaks bathrooms in 2026. These are not national averages – they’re numbers calibrated to this market, including San Fernando Valley labor rates and the material costs that show up in our written quotes before any work starts.
| Scope of Work | Typical Cost Range (Sherman Oaks, 2026) |
|---|---|
| Basic vanity swap (prefab cabinet, drop-in sink, existing plumbing) | $800 – $1,200 |
| Mid-range single vanity (semi-custom cabinet, undermount sink, new faucet) | $1,200 – $1,800 |
| Double vanity installation (60″-72″ cabinet, dual sinks, stone countertop) | $1,800 – $2,600 |
| Custom or furniture-style vanity with Caesarstone or Cambria countertop | $2,200 – $3,000 |
| Plumbing relocation (adding to any of the above) | $350 – $900 additional |
| Electrical work (new outlet, lighting upgrade, GFCI compliance) | $200 – $600 additional |
| Demolition and haul-away of existing vanity | $150 – $350 additional |
A few things push the number in either direction. On the low end, a straightforward swap – same footprint, same drain location, no tile disturbance – keeps labor hours tight and materials predictable. Sherman Oaks homes built in the 1960s and 1970s (a significant portion of the housing stock in neighborhoods like Magnolia Park and the streets south of Ventura Boulevard) sometimes have outdated galvanized supply lines behind the wall. When we open the cabinet space and find corroded pipe, replacing it is non-negotiable and adds to the written scope. That’s not a surprise charge – it gets documented in a revised change order before anyone touches it.
On the higher end, a floating or furniture-style vanity with a waterfall-edge Cambria quartz countertop requires a different installation method than a standard floor-mounted cabinet. The countertop material alone can run $600-$1,200 for a single-sink configuration in a premium stone. Kohler undermount sinks and Toto fixtures add quality, but they also add cost – usually $300-$700 beyond a builder-grade alternative. We name those brands in the quote so you know what you’re getting and can compare the number honestly.
What Affects Bathroom Vanity Installation Pricing in Sherman Oaks
- Vanity size and configuration: A 24-inch single vanity in a powder room is a fundamentally different job than a 72-inch double vanity in a primary bath. Labor time scales with size, and material cost per linear foot rises when you move into semi-custom or custom cabinet lines like KraftMaid or Wellborn. In Sherman Oaks, primary bathrooms in homes above Moorpark Street tend to run larger, and double vanities are the norm rather than the exception.
- Cabinet grade and construction: Stock prefab vanities from big-box stores cost less upfront but often need additional shimming, filler strips, or finish work to sit flush in older bathroom footprints. Semi-custom cabinets – the KraftMaid and Wellborn lines we source – are built to the specified dimension, which reduces install time and produces a cleaner result. The upfront cabinet cost is higher; the labor to make it fit is lower.
- Countertop material: A standard cultured marble top is priced into the lower end of the cost table above. Caesarstone or Cambria quartz requires fabrication and typically a separate template visit before the slab is cut. Natural marble, if that’s what the design calls for, adds more – both in material cost and in the care required during installation to avoid cracking at the sink cutout.
- Plumbing complexity: When the new vanity footprint matches the old one exactly, the supply and drain connections are straightforward. When the new design shifts the sink position, or when the customer is moving from one sink to two, the plumbing rough-in has to move. In Sherman Oaks, homes built before 1980 frequently have cast iron drain stacks, which require different cutting tools and additional labor compared to ABS plastic. We scope this before quoting, not after opening the wall.
- Tile and wall condition: A vanity removal almost always exposes drywall behind and beside the cabinet. In bathrooms where the original tile runs behind the vanity, removing the old cabinet can pull tile with it – especially if a previous installer used construction adhesive. If the wall needs new cement board or greenboard before the new vanity goes in, that’s a real line item. We photograph what we find and document it in the scope before the work continues.
- Permit requirements: Most straight vanity replacements in Sherman Oaks do not require a permit from the City of Los Angeles. However, if the work involves relocating drain lines, moving the vent stack, or modifying the electrical circuit (adding a new outlet or upgrading to GFCI protection), a permit may be required. We pull whatever permits apply. Work that requires a permit and doesn’t have one creates problems at resale, and that’s a cost to the homeowner that doesn’t show up until the worst possible moment.

AfterHow the Installation Process Works at Rowan Construction Group
Grant Rowan structured our process around one rule: the number in writing before anyone picks up a tool. Under Clause 1 of the Haven Standard, a flat written price with a written scope is delivered before work starts. Every time, on every job. That’s not a selling point – it’s how we’ve kept 4,000-plus projects across Sherman Oaks and the broader Los Angeles area within a few percent of the agreed cost since 2007.
Here’s what the typical vanity installation looks like on our end:
- On-site assessment: We measure the space, note the drain and supply locations, assess wall and subfloor condition, and ask about the countertop material and fixture preferences. If there’s an existing vanity, we look at how it’s connected and whether there’s any water damage behind or beneath it.
- Written quote: You receive a flat price with a line-item scope – cabinet, countertop, sink, faucet, labor, demolition, and any ancillary work identified during the assessment. No range that expands after work starts. No “call for a quote” runaround.
- Signed change order for anything new: If we open a wall and find corroded pipe or a failed water membrane, we stop, photograph it, and present a written change order. No work proceeds on that item until the change order is signed.
- Installation: Background-checked, uniformed crew. Existing vanity disconnected, removed, and hauled away. New cabinet set, leveled, and secured. Countertop and sink installed. Plumbing reconnected. Faucet set. Everything checked for leaks before we leave.
- Documented photo record: Before and after photos of the installation, including any conditions found behind the wall. The customer leaves with a record of what was done. This is included as a standard deliverable, not an upgrade.
The 365-Day Done Right Promise applies to every vanity installation we complete in Sherman Oaks. If it’s not right, Grant Rowan makes it right – and that’s written into the Haven Standard, not offered on a handshake.
How to Save on Bathroom Vanity Installation in Sherman Oaks
There’s a real difference between saving money and spending less – and in a vanity installation, they’re not always the same thing. Here’s where the math actually works in your favor:
- Match the new footprint to the old one. Keeping the same cabinet width and the same drain/supply location eliminates plumbing rough-in costs entirely. If the existing vanity is a 36-inch cabinet and the new one is also 36 inches, positioned the same way, the install is cleaner and faster. If you want to go wider, price out the plumbing relocation before committing – sometimes it’s only a few hundred dollars and worth it; sometimes the wall condition makes it significantly more.
- Choose semi-custom over custom where the standard sizes fit. A KraftMaid or Wellborn cabinet in a standard dimension looks and performs better than most site-built custom cabinetry at a lower total cost. The 30-, 36-, 48-, and 60-inch widths cover the vast majority of Sherman Oaks bathroom layouts.
- Consider quartz over natural stone for the countertop. Caesarstone and Cambria quartz surfaces are non-porous, don’t need sealing, and hold up well to the hard water common in the San Fernando Valley. Natural marble is beautiful but requires ongoing maintenance that adds cost over time. For most Sherman Oaks bathrooms, a Caesarstone countertop is the stronger long-term value.
- Bundle vanity work with other bathroom scope. If you’re already having us address a walk-in shower (typically $4,500-$12,000 in Sherman Oaks) or a broader bathroom remodel ($9,000-$28,000), adding the vanity to the same project reduces the per-trade mobilization cost. The crew is already there, the permits are already pulled, and the scope is already scoped.
- Get a second opinion on any quote you already have. Rowan’s Free Second Opinion offer is standing: bring a competitor’s written estimate and Grant Rowan will review it line by line at no charge. If the numbers are honest, we’ll tell you. If there’s a line item that doesn’t make sense, we’ll explain why. This is a real offer, not a bait-and-switch.
- Don’t skip the assessment to save time. Homeowners who buy a vanity and call for installation-only service sometimes discover that the new unit doesn’t fit the old plumbing or that the wall behind the old cabinet has moisture damage. Paying for a proper assessment upfront and having it reflected in a written scope is cheaper than discovering those issues midway through a job.

Sherman Oaks Bathroom Vanity Projects: What We See in the Field
Sherman Oaks is not a uniform housing market, and the vanity work reflects that. Along the streets north of Ventura Boulevard – Riverside Drive, Dickens Street, Addison Street – we work in post-war tract homes where bathrooms were built small and the plumbing is original. Cast iron drain lines, galvanized supply pipes, and tile that was set directly on wood framing without a waterproofing membrane. In those bathrooms, a vanity swap often reveals something that needs attention before the new cabinet goes in. We price what we find, in writing, and the homeowner decides.
South of the boulevard, in the hillside homes near Beverly Glen and the streets backing up to Mulholland, the bathrooms are larger and more recently remodeled – but that creates its own complications. Previous remodels sometimes used non-standard cabinet sizes or positioned plumbing in ways that make a like-for-like swap difficult. We’ve seen 47-inch vanity openings in homes where the original installer cut the tile instead of using a standard cabinet size. Custom-sizing a new cabinet to that opening adds cost; the written quote reflects it accurately.
The hard water in the San Fernando Valley also matters for fixture selection. Water hardness in this part of Los Angeles County accelerates mineral buildup on faucet aerators and around drain flanges. Kohler and Toto fixtures use ceramic disc cartridges that hold up better under those conditions than the brass ball valves in builder-grade faucets. It’s a real difference, and it shows up in how long the fixture lasts before needing service.
For homeowners considering a full bathroom update rather than just the vanity, the cost context is useful: a small bathroom remodel in Sherman Oaks typically runs $5,000-$12,000, and a primary bathroom remodel runs $9,000-$28,000 depending on tile, fixture grade, and whether the layout changes. A vanity installation at $800-$3,000 is often the most impactful single upgrade in a bathroom that’s otherwise in decent condition.
Bathroom Vanity Installation vs. Full Bathroom Remodel: Which Makes More Sense?
The vanity is often the first thing a buyer notices in a bathroom listing photo and the first thing a homeowner gets tired of looking at. That makes it a high-impact, contained upgrade when the rest of the bathroom is structurally sound. If the tile is in good shape, the floor is level, and the shower or tub is functional, a vanity replacement can refresh the whole room for $1,200-$2,500 without touching the rest.
The calculus changes when the subfloor shows moisture damage, the tile is cracking at the floor-to-wall joint, or the shower pan is leaking. Those conditions mean the bathroom needs more than a vanity – they mean the floor and possibly the wall substrate need to be addressed before any finish work makes sense. Putting a $2,500 vanity on a compromised subfloor is spending money in the wrong order.
Grant Rowan’s approach on an assessment visit is to tell you what we find, describe what it means, and give you the options in writing. If the bathroom only needs a vanity, that’s what we quote. If we find something that changes the scope, it goes on paper before the conversation continues.

FAQs: Bathroom Vanity Installation Cost in Sherman Oaks
How much does bathroom vanity installation cost in Sherman Oaks in 2026?
Bathroom vanity installation in Sherman Oaks costs between $800 and $3,000 for most residential projects. A basic prefab vanity swap with existing plumbing runs $800-$1,200; a mid-range single vanity with a new faucet and undermount sink lands around $1,200-$1,800; a double vanity with a stone countertop typically runs $1,800-$2,600 or higher depending on material selection. Call (213) 221-0788 for a written price on your specific bathroom – the estimate is free.
Is it cheaper to replace or repair a bathroom vanity?
Repair makes sense when the cabinet box is structurally sound and only the countertop, sink, or faucet needs replacing. A countertop-and-sink swap without touching the cabinet runs roughly $500-$1,000 depending on material. If the cabinet itself is damaged – delaminating, showing water damage at the base, or structurally compromised – replacement is almost always the better investment. A damaged cabinet that looks cosmetically repaired still has a failing substrate, and that shows up as a problem again within a few years. The assessment will tell you which situation you’re in.
How long does bathroom vanity installation take?
A standard single-vanity swap in a Sherman Oaks bathroom takes 4-8 hours when the plumbing footprint doesn’t change. A double vanity with a stone countertop that requires a separate fabrication visit runs across two days: one for cabinet installation and plumbing rough-in, and a second visit after the countertop is fabricated and delivered. Plumbing relocation or wall repair adds time. We give you a realistic completion timeline in the written scope – not a range that gets revised after the job starts.
Do I need a permit for vanity installation in Sherman Oaks?
Most straight vanity replacements in Sherman Oaks – same footprint, same plumbing connections, no electrical changes – do not require a City of Los Angeles permit. Permit requirements apply when the work includes relocating drain lines, modifying the vent stack, or adding or upgrading electrical circuits in the bathroom. We identify permit requirements during the assessment and pull whatever applies. Unpermitted work that required a permit is a documented liability at resale, and it’s not a shortcut we take.
Can Rowan Construction Group remove and haul away my old vanity?
Yes. Demolition and haul-away of the existing vanity is a line item in every installation quote – typically $150-$350 depending on vanity size and the complexity of disconnection. It’s priced separately so you see exactly what you’re paying for, and it’s included in the scope document you sign before work starts. We don’t leave a job site with materials on the floor.
What’s included in Rowan’s free estimate for vanity installation?
The free estimate includes an on-site assessment of the existing bathroom, written documentation of the vanity footprint, plumbing configuration, and any conditions observed behind or beneath the current cabinet. You receive a flat written price covering labor, materials (cabinet, countertop, sink, faucet, or any combination of those), demolition, and applicable ancillary work identified during the visit. The number on the estimate is the number on the invoice, with any scope changes documented in a signed change order before they occur. Call (213) 221-0788 to schedule.
