What is the cost of installing a new vanity and sink in a New Brunswick bathroom?

Installing a new vanity and sink in a New Brunswick bathroom costs $600-$3,500 for materials depending on what you choose, plus $300-$800 for professional installation if you're hiring a plumber or handyperson for the fixture connections. For a complete supply, installation, and finishing job (vanity, sink, faucet, supply lines, P-trap, and mirror), budget $1,200-$5,000 depending on the quality level.

Vanity pricing in NB covers an enormous range. A ready-to-assemble (RTA) stock vanity from a building supply or big-box store runs $300-$900 for a 24-36 inch cabinet with a laminate or cultured marble top. Mid-range vanities with solid wood or plywood-box construction, dovetail drawer joints, and soft-close hardware run $800-$2,000 in the 24-48 inch range. Semi-custom or fully custom vanities ordered through a kitchen and bath dealer run $2,000-$5,000+ depending on size, wood species, and finish. Floating (wall-mounted) vanities have become popular in NB bathroom renovations — they create the illusion of more floor space, are easier to clean under, and look contemporary. They cost $800-$2,500 for the vanity unit and require wall blocking or a properly located stud for mounting support.

Countertop and sink choice significantly affects the final cost. Cultured marble integrated sink-and-top combinations (common on stock vanities) are functional and affordable, typically included in vanity pricing at the lower end. Quartz countertops with an undermount sink run $600-$1,500 for a bathroom-scale slab, custom-cut and installed — a worthwhile upgrade in a master ensuite or a bathroom where the counter sees heavy use. Vessel sinks sit on top of the vanity counter and have become a popular design choice; they run $150-$600 for the sink itself but require a taller vanity height and a specific type of faucet (a taller vessel faucet), so budget the full combination together.

Faucet selection matters both aesthetically and functionally. A quality single or widespread faucet from Moen, Delta, or Kohler runs $150-$500 — these brands offer solid warranties (Moen's lifetime warranty is particularly strong) and replacement parts that will still be available in 10+ years. Budget faucets from off-brand sources frequently have ceramic cartridge failures within 3-5 years in NB's mineral-rich water conditions, so the upgrade to a reputable brand pays for itself.

For installation, if your existing plumbing rough-in (the supply lines and drain rough-in in the wall) is already in the right location for your new vanity, installation involves connecting the water supply lines (from shut-off valves to faucet), installing the P-trap from the drain to the wall rough-in, and ensuring everything is sealed and leak-free. A confident DIYer can do this work above the shut-off valves — it's genuinely learnable and doesn't require a licence. If you need to relocate the drain, raise or lower the supply line height, or change the rough-in configuration, that's licensed plumber territory requiring a TSANB inspection in NB.

If the old vanity has been in place since the 1980s or earlier, it's common in NB homes to find that the shut-off valves are seized, the supply lines are galvanized steel with corrosion buildup, or the drain P-trap is an old chrome trap that crumbles when touched. Budget $300-$600 to have a licensed plumber replace shut-off valves and supply lines while the vanity is being changed — this is inexpensive insurance against a leak problem in a finished wall.

Installation timeline for a vanity swap is typically a half-day to full-day job once the old vanity is out. Demolition and disposal of the old unit takes an hour or two; setting, levelling, and connecting the new vanity and faucet takes 2-4 hours depending on complexity. If tile work around the vanity needs patching or the backsplash is being updated at the same time, add another half-day.
