How much does it cost to add a kitchen island during a renovation in NB?

A kitchen island addition in New Brunswick typically costs $3,000-$15,000 depending on size, whether it includes plumbing or electrical, and how it's built — a standalone freestanding island is at the low end, while a built-in island with a prep sink, electrical outlets, and seating overhang is at the high end. Getting clear on what you actually want before budgeting is the most important step.

A basic freestanding kitchen island — a standalone cabinet unit with a countertop, purchased as a ready-to-assemble or off-the-shelf unit — runs $1,500-$4,000 including installation in NB. These are a practical option when your kitchen layout doesn't allow for permanent fixture changes, or when you're in a rental or planning to move in a few years. The limitation is that they can't include plumbing and are often less visually polished than built-in options.

A built-in kitchen island framed and finished to match your existing cabinetry is a much more significant project. The cabinetry component alone — whether stock, semi-custom, or fully custom — runs $2,000-$8,000 depending on the size and cabinet quality. Add a quartz countertop (the current standard in NB renovations) at $60-$120/sq ft installed, and a 4×3 foot island top adds another $800-$2,000. If your island design includes a seating overhang for bar stools — extremely popular in NB open-concept kitchens — the countertop extends further and costs more, and you need to confirm the cabinets are designed to handle the cantilevered weight.

Electrical and plumbing additions change the budget significantly. Adding one or two electrical outlets to an island requires running new wiring from your panel — typically $500-$1,500 depending on panel location and access. A pendant light fixture or two over the island adds another $300-$800 for wiring and fixtures. Adding a prep sink with hot and cold supply lines and a new drain stub-up through the floor is the biggest cost jump — plan on $2,000-$4,500 for the plumbing rough-in, fixtures, and connections, plus TSANB inspection. All new electrical circuits and plumbing rough-in require permits in NB, so budget $150-$350 for permits on top of the trade costs.

Most NB kitchen islands run between 4 and 6 feet in length and 3 to 4 feet in width, but your specific kitchen dimensions dictate what's possible. The standard clearance requirement between an island and surrounding cabinets or walls is 42 inches minimum on all working sides — 48 inches is more comfortable. Many NB older homes have kitchens that are too small for a comfortable island, and it's worth getting an honest assessment of your kitchen dimensions before committing to the idea.

From a renovation planning standpoint, the smartest time to add a kitchen island is during a full kitchen renovation when the floor is already open, electrical is already being run, and the trades are on site. Adding an island as a standalone project later is more disruptive and proportionally more expensive because you're paying mobilization costs for each trade separately.
