Cost to Replace a Bathroom Vanity

Replacing a bathroom vanity is one of the highest-impact, lowest-cost upgrades in a bathroom. The walls, floor, and shower stay untouched, so you get a fresh cabinet, a new top, and a new faucet without the disruption or budget of a full remodel. But the price homeowners quote each other — "a couple hundred bucks for the cabinet" — is only one line on the bill. The top, the sink, the faucet, the plumbing reconnect, the removal and disposal, any wall repair, and the labor all stack on top, and a couple of those items can quietly double the total.

This guide breaks the cost down honestly, by tier and by line item, so you can build a realistic budget before you shop. It is written from the perspective of a master bathroom remodel in a Northern California home, where slab-on-grade foundations, 1960s–80s ranch plumbing, and hard water all shape what the reconnect actually costs.

The three price tiers, at a glance

Vanity cost sorts cleanly into three tiers, driven almost entirely by the cabinet you choose. These are installed ranges for a standard 30-to-48-inch single vanity in the Sacramento-Placer market where the sink stays in its existing location:

• Stock / big-box — $900 to $1,800 installed. A ready-made vanity from a home center ($200–$800 for the cabinet), usually sold as a combo with a cultured-marble top and integrated bowl, plus a mid-grade faucet and a same-spot plumbing reconnect. The fastest, cheapest path, and a genuinely good look if you pick carefully.
• Semi-custom — $2,000 to $4,500 installed. A better cabinet ($800–$2,500) with a solid-wood face, soft-close drawers, and a separately fabricated quartz or granite top, an undermount bowl, and a name-brand faucet. This is the tier most Placer County remodels land in.
• Custom — $5,000 to $10,000+ installed. Cabinetry built to your wall and finish ($2,500–$6,000+), a premium stone or slab top, high-end fixtures, and often a floating design or relocated plumbing. Chosen when the vanity is the centerpiece of the room.

The jump between tiers is not just the cabinet — it is the top material, the faucet grade, and how much plumbing has to move. The next sections show exactly where the money goes.

Why homeowners replace a vanity — and when it makes sense

A vanity swap earns its place when the cabinet is water-damaged at the toe kick, the cultured-marble top is stained or cracked, the storage no longer works for the household, or the whole thing simply looks dated against a bathroom you otherwise like. Because nothing structural changes, it is the rare bathroom project that delivers a near-total visual refresh for a modest, predictable budget.

It makes the most sense as a standalone job when the surrounding room is in good shape. If the flooring and lighting are also on their way out, folding the vanity into a larger scope saves on mobilization, drywall, and paint. If you only want to change the surface and keep the cabinet, the cheaper move is a vanity-top-only replacement, which skips the cabinet and most of the labor. The rest of this guide assumes you are replacing the whole vanity.

The full line-item cost breakdown

Here is every item that lands on a vanity-replacement estimate, with realistic 2026 ranges for our service area. Add the lines that apply to your project to build your own total:

• Vanity cabinet: $200–$800 stock, $800–$2,500 semi-custom, $2,500–$6,000+ custom, for a 30-to-48-inch box. The single biggest variable in the whole project.
• Countertop + sink: $150–$400 for a cultured-marble combo top with integrated bowl; $300–$1,500 for a separately fabricated quartz or granite top with an undermount bowl, templated and installed.
• Faucet: $80–$350 for a solid mid-grade fixture; $350–$800+ for premium finishes and widespread configurations.
• Plumbing reconnect (same location): $200–$500 for new supply stops, a P-trap, and the faucet and drain hookup.
• Plumbing rough-in changes (relocate drain/supply): $600–$2,000 when the sink moves or a floating design forces the lines to a new height, including the drywall work to open and close the wall.
• Removal & disposal of the old vanity: $75–$250 to disconnect, demo, and haul the old cabinet, top, and sink.
• Wall repair behind the old cabinet: $100–$600 to patch, texture, and paint the wall the old vanity was hiding — almost always needed.
• Installation labor: $400–$900 to set and level the cabinet, set the top, mount the faucet, and connect the plumbing.
• Permits & inspection (only if plumbing/electrical moves): $150–$600 depending on jurisdiction.

Total ranges by tier for a standard 30–48" vanity

Stack the line items and the three tiers settle into these installed totals for a same-location single vanity in the Sacramento-Placer market:

• Stock / big-box: $900 – $1,800. Combo top, mid-grade faucet, same-spot reconnect, removal, and a light wall touch-up. Often a one-day job.
• Semi-custom: $2,000 – $4,500. Solid-wood cabinet, fabricated quartz top with undermount bowl, name-brand faucet, reconnect, removal, and wall repair. Spans two visits when the stone is templated.
• Custom: $5,000 – $10,000+. Built-to-fit cabinetry, premium stone, high-end fixtures, and frequently a floating design or relocated plumbing that adds rough-in and blocking labor.

If any of your plumbing has to move, add the $600–$2,000 rough-in line to whichever tier you are in — that is the item most likely to carry a project from one tier's total into the next.

What drives the price up or down

• Whether the sink moves. Reusing the existing drain and supply keeps the plumbing line at $200–$500. Relocating rough-in inside the wall is the single fastest way to add $600–$2,000 to the job.
• Single vs. double vanity. A double is a second sink, not just a wider box, so a second drain, vent, and supply have to be roughed into the wall. That is why a single-to-double conversion runs several thousand dollars more than a like-for-like single swap.
• Floating / wall-mount design. A wall-mount cabinet needs solid blocking added inside the wall and often a lowered or relocated drain, adding $300–$1,200 over a comparable freestanding vanity.
• Countertop material. A cultured-marble combo top is the cheapest path; a separately fabricated quartz or granite top with an undermount bowl adds material, fabrication, and one to two weeks of lead time.
• Slab-on-grade foundation. Most Sacramento ranch homes sit on a slab, so any drain relocation routes through the wall rather than dropping into a crawl space — more labor than a raised-floor home.
• Corroded pipe and valves. Sacramento's hard water is rough on galvanized supply and old shutoff valves. If the wall opens and the pipe is failing, replacing it while access is easy is smart but adds cost.
• County. Placer County labor (Roseville, Rocklin, Lincoln, Auburn) tends to run a touch higher than parts of Sacramento County, and permit fees differ by jurisdiction.

How a vanity replacement actually runs

• Planning: Measure the wall and the existing drain height, choose the cabinet, top, and faucet, and confirm whether any plumbing has to move (which decides whether a permit is needed).
• Removal: Shut off the water, disconnect the supply and drain, pull the old top and cabinet, and haul it out.
• Wall prep: Patch, texture, and paint the wall the old vanity was hiding, and add blocking if the new cabinet is wall-mounted.
• Set & connect: Level and secure the new cabinet, set the top and bowl, mount the faucet, and reconnect supply and drain with new stops and a fresh P-trap.
• Stone lead time (if applicable): A custom quartz or granite top is templated after the cabinet is set and installed one to two weeks later, so the job spans two visits.

A like-for-like swap with a combo or prefab top is usually a single day. A fabricated stone top spans two visits, and any plumbing relocation or floating design stretches it to two or three working days because the wall has to be opened, inspected, and refinished. This work is one piece of a broader bathroom vanity replacement scope and coordinates cleanly with flooring, lighting, and the rest of a full remodel.

When to call a pro — and getting an accurate estimate

A same-spot cabinet swap with a combo top is within reach of a confident DIYer. The line where it pays to call a pro is anywhere plumbing moves: relocating a drain or supply, hanging a floating cabinet, fabricating a stone top, or opening a wall that turns out to hide corroded galvanized pipe. Those are the items that leak, fail inspection, or blow the budget when they are guessed at.

The reason no two of these projects price the same is that the biggest variable — whether your plumbing can stay put — often can't be judged until the old vanity is out. The reliable way to get a real figure is a quick in-home look at the cabinet and the existing rough-in.
