What should I expect to pay for a double vanity upgrade in a Port Coquitlam bathroom?

A double vanity upgrade in a Port Coquitlam bathroom typically costs $3,000 to $8,000 fully installed, covering the vanity unit, countertop, two sinks, two faucets, plumbing connections, and any necessary modifications to accommodate the wider cabinet. The final cost depends heavily on the vanity style, countertop material, and whether your existing plumbing can support two sinks without major rough-in changes.

The vanity unit itself ranges widely in price. A stock 60-inch double vanity from a bathroom showroom or supplier runs $1,000 to $3,000 including the countertop and sinks. A 72-inch unit offers more counter space and runs $1,500 to $4,000. Semi-custom or custom vanities — built to specific dimensions for your bathroom — run $2,500 to $6,000+. Floating (wall-mounted) double vanities are popular in modern renovations and cost $1,200 to $4,500 for the unit, but require blocking installed in the wall framing to support the weight, adding $200 to $500 for the structural reinforcement.

Countertop material is a major cost variable. If your vanity does not come with an integrated top, you will need to select one separately. Quartz countertops for a 60 to 72-inch double vanity run $600 to $1,500 installed. Cultured marble or solid surface tops cost $400 to $1,000. Natural stone (granite or marble) runs $800 to $2,000. Laminate is the budget option at $200 to $500 but is not recommended for high-moisture bathrooms in Metro Vancouver's humid climate.

Two faucets are needed for a double vanity, obviously, and quality bathroom faucets run $150 to $600 each installed. Budget $300 to $1,200 for the pair. Widespread faucets (with separate handles and spout) are the most popular choice for double vanities and cost slightly more than single-hole or centerset styles.

Plumbing is where costs can escalate. If your current bathroom has a single vanity with one set of supply lines and one drain, adding a second sink requires running a new hot and cold supply line and adding a second drain connection. In Port Coquitlam homes — most built between the 1970s and 2000s with copper supply and ABS drain piping — this plumbing work typically costs $800 to $2,500 depending on how far the new drain and supply lines must travel. If the existing drain stack is directly behind the current vanity location, adding the second sink on the same wall is relatively straightforward. Moving to a different wall is significantly more expensive.

A licensed plumber is required for any plumbing rough-in work under BC code. If you are adding new drain or supply connections, a plumbing permit from the City of Port Coquitlam is required (typically $100 to $250). If you are simply connecting two sinks to existing rough-in points that were already stubbed in — common in newer Port Coquitlam homes where the builder roughed in for a double vanity — no permit is needed and a qualified installer can handle the connections for $300 to $600.

Electrical considerations often come up during a double vanity upgrade. A wider vanity usually means upgrading the vanity light fixture to a longer bar light or installing two separate lights above each mirror. New light fixtures add $200 to $800 installed. If the vanity is moving to a different wall or expanding significantly, you may need to relocate or add a GFCI electrical outlet — a licensed electrician should handle this at $200 to $500.

Space requirements matter. A 60-inch double vanity needs a bathroom at least 8 feet wide to allow comfortable clearance on both sides, and you need a minimum of 30 inches of centre-to-centre spacing between the two sinks. Many Port Coquitlam bathrooms from the 1980s and 1990s are 5 feet by 8 feet or 5 feet by 9 feet, which can accommodate a 60-inch double vanity along one wall but may feel tight. Measure carefully before purchasing.

For a budget double vanity upgrade keeping existing plumbing locations, expect $3,000 to $4,500. A mid-range upgrade with a quality vanity, quartz countertop, new plumbing connections, and updated lighting runs $5,000 to $7,000. A premium upgrade with a custom or semi-custom vanity, natural stone or premium quartz top, widespread faucets, and associated plumbing and electrical work reaches $7,000 to $10,000+.
