Bathroom vanity installation cost in BC depends on the type of vanity — and on one practical question.
Does the plumbing stay where it is?
A swap that keeps the drain and supply lines in place is a cabinet job. A swap that moves them is a plumbing project with a vanity attached — a very different invoice wearing the same name — and the ranges below include the cabinet, the top, the sink and faucet, and the labour to install them.
The short version: a basic single vanity installed runs $900–$2,500. A mid-range single or basic double lands at $2,000–$5,500. A quality double vanity with a stone top runs $4,500–$9,000, and a floating wall-mounted vanity reaches $6,000–$12,000+.
1. Prices by Vanity Type

2. Why Doubles and Floating Vanities Cost More
The jump from single to double is the biggest step in the table.
And it is not just an extra sink — it is a wider cabinet, a longer stone top with two cutouts, two faucets, and a drain layout that has to handle two sinks without crowding behind the doors, every pipe and tailpiece negotiating for space in a cabinet that was never as roomy as the showroom made it look.
Floating vanities sit at the top for a structural reason — several, stacked. The wall framing has to be reinforced to carry the load. The drain and supply lines have to hide cleanly inside the wall. There is no floor contact to hide a slightly uneven wall. Every part of the install has to be precise.
And precision costs money.
3. The Vanity Share of a Full Renovation
A vanity replacement rarely happens on its own.
In most Abbotsford and Fraser Valley bathroom projects it is one line inside a larger renovation — one line among twenty — and for a typical mid-range bathroom renovation, the vanity usually accounts for 10–20 percent of the full project cost:
- A $15,000 bathroom remodel will carry a $2,000–$3,500 vanity.
- A $30,000 ensuite overhaul can absorb a $5,000–$8,000 double vanity with a stone top and still stay in proportion.
The vanity decision also affects other lines. A wider vanity eats into shower or toilet clearances. A double vanity in a bathroom plumbed for a single means new drain lines in the wall. A vessel sink on a floating vanity changes where the drain exits. If the vanity is part of a bigger renovation, choose it early — before the plumber roughs in, before anything is sealed behind drywall — because moving drain stubs after the fact is expensive, the kind of expensive that comes from undoing finished work. Our bathroom renovation cost guide for Abbotsford lays out how the other components compare, so the vanity can be weighed against tile, plumbing and electrical.
4. Labour by Type
Singles. The cabinet, top and sink come together, the plumber disconnects the old fixture, the new one drops in, and connections are made to the existing drain and supply stubs — drain to drain, supply to supply, nothing moved, nothing rerouted. Labour typically runs $500–$1,200 when nothing moves.
The cabinet drives the range.
A builder-grade 30-inch unit from a big-box store sits at the low end, while a 48-inch semi-custom single — quartz top, undermount sink, quality hinges that close like they mean it — lands in the middle, and most half bathrooms and smaller main bathrooms in older Abbotsford ranches take a 30–36 inch single, which keeps both material and labour modest.
Doubles. Allow about 60 inches of clear wall for the cabinet, plus room to open drawers. Room to stand. Room for two people to glare at each other over toothpaste. The installation adds a second faucet connection and a drain setup with two sink tailpieces tying into one drain line — two sinks, one exit, a small plumbing negotiation behind the cabinet doors — and you budget roughly $800–$1,800 in labour for a like-for-like swap, more if the drain has to be repositioned. The cost surprise with doubles is usually the top: two sink cutouts in a stone slab mean more fabrication, and if the cabinet is 72 inches, the slab may need a seam.
Floating vanities. The wall needs solid blocking or a reinforced section of framing behind the cabinet, which usually means opening the drywall — there is no faking this part, because the cabinet, the top, the sinks and two people’s morning leaning all hang off that wall — and the drain and supplies route inside it and exit at exact heights, a quarter inch being the difference between hidden and humiliating. The cabinet hangs level on a cleat system and the top goes on with no visible support. Labour alone can run $1,500–$3,000 for a floating installation that starts with opening the wall, before the cabinet and top. The payoff: the floor reads continuous, cleaning is easier, and a floating vanity makes a small BC bathroom feel noticeably bigger. It is not the budget pick.
5. DIY vs Hiring a Plumber
The cabinet work on a vanity swap is DIY-friendly.
The plumbing connections are the part that carries risk.
If the new vanity is the same width and the drain and supply stubs stay exactly where they are, a competent DIYer can handle the swap: shut off the water, disconnect the supply lines and drain, remove the old cabinet, set and level the new one, attach the top, reconnect, check for leaks. The tools are basic — a wrench, a bucket, patience. The risk is not.
The risk is a slow leak at a supply connection inside a closed cabinet — a drip a minute, behind the shampoo bottles — which can go unnoticed for months in a wet coastal climate, and by the time the cabinet base swells, the floor underneath is usually damaged too, quietly, expensively, in the dark.
Hire a professional when any of these apply:
- The drain or supply lines move at all.
- The new vanity is wider than the old one and the plumbing has to shift.
- The shutoff valves are old or corroded, which is very common in pre-2000 Fraser Valley homes.
- A floating vanity needs wall reinforcement.
- The bathroom sits over finished living space, where a leak would cause real damage.
A plumber’s vanity rough-in and hookup typically costs $500–$1,500 on its own. A common split — the split half the Valley seems to land on — is the homeowner handling the cabinet as a DIY project and a licensed plumber handling the final connections. Many installers work that way.
6. What Moves the Price
- Plumbing movement. Nothing affects the bill like relocating the drain. Keeping the vanity in its existing footprint is the single biggest cost control on this project.
- Cabinet construction. Stock flat-pack units, semi-custom plywood cabinets, and fully custom vanities are three different price worlds — and the gap widens with width.
- Top material. Cultured marble or solid surface at the low end, quartz in the middle — where most budgets land, and land happily — natural stone at the top. Every sink cutout adds fabrication cost.
- Sink style. An undermount sink bonded into the top costs more to fabricate than a drop-in, and a vessel sink on a floating vanity changes the drain geometry.
- Hardware and finish. Soft-close drawers, solid brass faucets and finished interiors add up. Worth it on a daily-use fixture, but budget them honestly.
- Wall condition. Rot or mould behind the old vanity, discovered on removal, has to be remediated before the new cabinet goes in. Budget a contingency of 10–15 percent for this.
Frequently Asked Questions
How much does bathroom vanity installation cost in BC?
For 2026, plan on $900–$2,500 installed for a basic single vanity, $2,000–$4,500 for a mid-range single, $4,500–$9,000 for a quality double vanity with a stone top, and $6,000–$12,000+ for a floating wall-mounted vanity. Labour typically adds $500–$1,800 on top of the fixture when plumbing stays in place. All figures are planning ranges. Not quotes.
How much does a double vanity installation cost?
A basic 60-inch unit typically runs $3,500–$6,500 in BC, and a quality version with a quartz top and soft-close hardware runs $4,500–$9,000. The labour is higher than a single vanity because of the second faucet connection, the dual-sink drain layout and the longer stone top with two cutouts.
Can I replace a bathroom vanity myself?
Yes — with a caveat. A large one. If the new vanity is the same width and the drain and supply lines do not move, a competent DIYer can handle the cabinet swap — and many homeowners hire a plumber just for the final supply and drain connections, the twenty minutes where the risk actually lives — while any plumbing relocation, floating vanity wall reinforcement, or work in a bathroom over finished living space means hiring a professional, full stop.
Do I need a permit to replace a bathroom vanity in BC?
A like-for-like vanity swap with no plumbing or electrical changes generally does not require a permit. Moving drain or supply lines, adding an electrical circuit for lighting or outlets at the vanity, or opening walls for structural work generally does need permits and inspections in BC. Confirm with your municipality before work starts, since the rules vary.
How long does it take to install a bathroom vanity?
A straightforward swap takes a day. A single vanity with new shutoff valves and a stone top typically runs one to two days once materials are on site. A double vanity with plumbing adjustments takes two to three days, and a floating vanity — wall opened, blocking in, drywall repaired and finished around it — can stretch to a week when drywall repair and finishing are included.
Planning a Bathroom Vanity Installation in BC?
Start with the plumbing footprint.
If the drain and supplies can stay where they are, most of the budget goes into the cabinet and top — which is where it should go on a fixture used every day, twice a day, by everyone in the house — and if they have to move, get a plumber involved before ordering anything — before the cabinet, before the top, before the faucets you have already picked out — and order the vanity early so the rough-in matches the fixture instead of the other way around.
