Adding a custom bathroom vanity is one of the highest-return upgrades an Ontario homeowner can make to a primary or ensuite bathroom. A new vanity changes the entire visual identity of the room, adds meaningful storage, and — when paired with a quality countertop and sink — delivers results that compete with a full bathroom renovation at a fraction of the cost.
Blackwood Kitchens designs and installs custom bathroom vanities across Cambridge, Kitchener, Waterloo, Guelph, Brantford, and Woodstock. Our cabinetry team builds vanities to the exact dimensions of your bathroom — not to standard box-store sizing — with the same furniture-grade quality we apply to custom kitchens and walk-in closets.

Bathroom Vanity Cost in Ontario 2026
Bathroom vanity costs in Ontario depend on the cabinet source (stock, semi-custom, or fully custom), countertop material, sink configuration, and installation complexity. Here is a practical breakdown for Ontario homeowners in 2026:
Stock Vanity Supply and Installation: $800–$3,000
Stock vanities — pre-built in fixed widths (24", 30", 36", 48", 60") — are available at big-box retailers and carry the lowest price point. Supply cost runs $400–$1,500 depending on size and finish quality. Professional installation adds $400–$1,500. The key limitation of stock vanities is sizing: older Ontario homes with non-standard alcove dimensions end up with filler panel gaps or awkward countertop overhangs. Stock vanities also use lower-grade materials (MDF doors, particleboard boxes) more susceptible to bathroom moisture.
Semi-Custom Vanity Supply and Installation: $2,500–$6,000
Semi-custom vanities allow selection of width (often in 3" increments), door style, and finish, but are manufactured in standard box configurations. They offer better quality than stock — typically solid wood doors and plywood boxes — but still carry sizing limitations and finish restrictions. Installed cost ranges from $2,500–$6,000 for a single vanity.
Fully Custom Bathroom Vanity Supply and Installation: $5,000–$15,000+
A fully custom bathroom vanity is built to your bathroom's exact dimensions — width, height, depth, and drawer configuration — with solid wood and plywood box construction. Every detail is specified: door style, finish colour, internal organization, drawer heights, soft-close hardware throughout, and specialty items (pull-out hampers, integrated outlets, custom toe kicks). Single vanity installed cost: $5,000–$9,000. Double vanity installed cost: $7,500–$15,000+. Ranges include supply, countertop, undermount sink, and professional installation.
Bathroom Vanity Types: Which Suits Your Ontario Bathroom?
Floating (Wall-Mounted) Vanities
Floating vanities are mounted directly to the wall with no floor contact. They create a modern, open look that makes bathrooms read as larger — particularly valuable in Ontario's older housing stock where bathrooms tend to be compact. They require solid blocking in the wall to carry the load. Floating vanities are the most popular choice for primary ensuite upgrades in Waterloo, Guelph, and Cambridge's newer housing segments.
Freestanding Vanities with Legs or Cabinet Base
Traditional freestanding vanities rest on the floor on legs or a closed cabinet base. Easier to install in existing bathrooms (no wall blocking required), they offer more storage and tend to suit traditional and transitional design styles. They dominate main-floor bathroom renovations in Cambridge, Kitchener, and Guelph's older home segments.
Double Vanities
Double vanities — two sinks on a shared countertop and cabinet run — are the standard expectation in primary ensuites for Ontario homes above the $600,000 price point. A well-sized double vanity typically runs 60"–72" wide. Custom double vanities from Blackwood Kitchens are built to the exact alcove width of your ensuite, eliminating gaps and sizing compromises of standard double units.
Corner Vanities
Corner vanities are built to fit diagonally into a bathroom corner, freeing floor space in tight powder rooms and compact bathrooms. They require full custom construction to match your specific corner geometry — stock and semi-custom corner vanities are rare and poorly proportioned.
Vanity Countertop and Sink Options
Quartz Countertop with Undermount Sink
The most popular choice for Ontario bathroom vanity upgrades. Quartz countertops are non-porous (no sealing required), highly stain-resistant, available in a wide colour range, and easy to clean. Undermount sinks provide a seamless look and easy countertop cleaning. Installed cost for a quartz countertop with undermount sink on a standard single vanity: $900–$2,200 depending on grade and width.
Solid Surface (Cultured Marble or Acrylic)
Solid surface countertops come in integrated sink configurations — sink and countertop are one seamless unit with no seam to clean around. Cost-effective at $600–$1,200 installed, but offer less visual appeal than quartz and are more susceptible to yellowing and scratching over time.
Natural Stone (Marble, Quartzite)
Natural stone is specified in high-end primary bathroom renovations in Waterloo, Guelph, and Cambridge. It requires annual sealing against moisture and cosmetic staining but delivers an irreplaceable material look. Installed cost: $1,800–$4,500+ depending on stone selection and vanity width.
Why Blackwood Kitchens for Bathroom Vanity Installation in Ontario
We build custom vanities using the same construction standards as our custom kitchen cabinetry: solid wood door frames, plywood box construction, soft-close drawer slides and hinges throughout, and finishes applied under controlled factory conditions — not painted on-site. Because we supply the cabinet, countertop, and sink as a coordinated package, you get one point of contact for the complete installation rather than coordinating between a cabinet supplier, countertop fabricator, and plumber separately. We handle countertop templating, coordinate the sink cutout, and reconnect plumbing as part of the service.

Frequently Asked Questions: Bathroom Vanity Installation Ontario
How much does it cost to install a bathroom vanity in Ontario?
Installed bathroom vanity cost in Ontario ranges from $800–$3,000 for a stock unit, $2,500–$6,000 for semi-custom, and $5,000–$15,000+ for a fully custom vanity with quartz countertop and undermount sink. The biggest cost driver is whether the cabinet is stock, semi-custom, or built to your exact dimensions.
How long does bathroom vanity installation take?
Replacing a stock or semi-custom vanity can be done in a single day. A fully custom vanity requires 4–6 weeks of production lead time, plus two installation visits (cabinet and countertop), with the full project typically complete within 6–9 weeks of the initial consultation.
Can a bathroom vanity be installed without a plumber?
Basic vanity swaps — where the new vanity uses the same plumbing rough-in locations as the old one — do not require a separate plumber. We handle plumbing reconnection (shut-off valves, drain, supply lines) as part of our installation service. Moving the drain location, adding new supply lines, or making permit-required changes requires a licensed plumber.
What bathroom vanity width should I choose?
Single vanities for powder rooms and main bathrooms typically run 24"–48". Primary ensuite double vanities run 60"–72". The main advantage of a custom vanity is that it is built to your exact available width — critical in older Ontario homes where bathroom alcoves rarely conform to the standard widths stock and semi-custom units are built around.

Yes. We install custom bathroom vanities across Cambridge, Kitchener, Waterloo, Guelph, Brantford, and Woodstock. Free in-home consultations are available in all locations. Call (519) 281-1000 to book yours.
