In Ottawa, bathroom vanity installation labour costs $350 to $900 in 2026 for a straightforward swap where the new vanity matches the old footprint and the plumbing stays in place. Including the vanity itself, most homeowners spend $900 to $2,200 for a standard 30- to 48-inch unit with a stock top, and $2,500 to $5,500 for a 60- to 72-inch double vanity with a quartz top and undermount sinks. Add $250 to $600 if the drain and supply lines need to be relocated, $150 to $400 for a new faucet install, and $200 to $500 for wall-mounted or floating vanities that require blocking inside the wall.

Labour is priced by complexity, not by the price of the vanity you bought. A like-for-like replacement of a 30- or 36-inch freestanding vanity — remove the old unit, set the new one, connect the P-trap and supply lines, caulk and seal — takes a plumber or carpenter two to four hours and runs $350 to $650 in Ottawa. A 48- to 60-inch unit takes longer and typically costs $500 to $850. A double vanity of 60 to 72 inches with two drains and two faucets runs $700 to $1,200 in labour. Wall-mounted flo...
If the plumbing is not moving and the vanity is freestanding, an experienced handyman or carpenter is usually sufficient and cheaper. If drains or supply lines are being relocated, if you are converting to a floating unit, or if the existing shutoff valves are seized or corroded, hire a licensed plu...
The unit itself is usually the larger half of the budget. Stock 24- to 30-inch vanities with a cultured marble or engineered top from a big-box retailer start around $300 to $700 in Ottawa. A 36- to 48-inch mid-range unit with soft-close doors, a plywood box, and a quartz top typically costs $800 to $1,800. Semi-custom and Canadian-made cabinetry in the same width runs $1,500 to $3,500. Double vanities of 60 to 72 inches range from $1,200 for basic stock units to $4,500 or more for solid-wood co...
Most vanity projects go over budget for predictable reasons. The first is size change: swapping a 30-inch vanity for a 48-inch one leaves unfinished flooring, unpainted wall, and often a mismatched backsplash where the old unit sat, adding $200 to $800 in patching, painting, and flooring work. The second is plumbing position — a wider or narrower cabinet frequently means the existing drain no longer lines up with the new sink, requiring the drain to be moved inside the wall at $250 to $600. The ...
If you are also replacing the toilet, faucet, flooring, or lighting, do it all in one visit. Trades charge a call-out and mobilization each time they attend, so combining tasks into a single appointment typically saves $150 to $400 compared with booking them separately over several months.
Replacing a bathroom vanity in the same location with no change to the plumbing rough-in does not require a City of Ottawa permit — it is treated as a fixture replacement. A plumbing permit is generally required when you relocate or add drains, vents, or water supply piping, which is common when converting a single vanity to a double or shifting the sink to a different wall. Ontario's plumbing code governs trap arm length, venting, and fixture clearances, and a properly installed vanity needs ad...
Decide first whether you are doing a straight swap or a reconfiguration, because that single choice roughly doubles the labour. Measure the existing vanity width, depth, and the drain height and horizontal offset from the wall before shopping, and confirm the new unit's plumbing cut-out will clear your existing rough-in. When requesting quotes, tell each contractor the current and new vanity sizes, whether plumbing is moving, whether you need old-unit disposal, and whether faucet, mirror, or lig...
Labour alone runs $350–$900 in Ottawa for 2026, depending on size and whether plumbing moves. Including the vanity, most homeowners spend $900–$2,200 for a standard 30- to 48-inch unit and $2,500–$5,500 for a 60- to 72-inch double vanity with a quartz top.
A like-for-like swap of a 30- to 36-inch vanity costs $350–$650 in labour, a 48- to 60-inch unit costs $500–$850, and a double vanity costs $700–$1,200. Floating wall-mounted vanities run $800–$1,500 because they need in-wall blocking and a relocated drain.
Not always. If the vanity is freestanding and the plumbing stays put, an experienced handyman or carpenter can do it. Hire a licensed plumber if drains or supply lines are moving, if you are installing a floating vanity, or if the existing shutoff valves are old and likely to fail.
No permit is needed for a straight fixture replacement in the same location. A plumbing permit is generally required if you relocate or add drains, vents, or supply piping — for example, when converting a single vanity to a double.
Relocating the drain and supply lines inside the wall typically adds $250–$600 in Ottawa, and more if the wall is tiled or the drain must be re-vented. Replacing seized shutoff valves at the same time adds another $150–$350.
