How much does it cost to build a basement laundry room in Metro Vancouver?

Building a dedicated laundry room in a Metro Vancouver basement typically costs between $5,000 and $18,000, depending on whether plumbing is already roughed in and how much finishing work the space needs. If your home already has washer and dryer hookups in the basement — as many Metro Vancouver homes do — the cost leans toward the lower end. If you are adding plumbing from scratch, the price climbs significantly due to the concrete cutting and drain work involved.

For a basement that already has washer/dryer hookups and basic finishing, creating a proper laundry room involves framing a partition wall to enclose the space, installing a door, adding adequate lighting and electrical outlets, upgrading the flooring, and perhaps installing a laundry sink and countertop for folding. This scope runs $5,000 to $9,000. The breakdown typically includes framing and drywall ($1,500 to $3,000), electrical work for dedicated circuits and lighting ($1,000 to $2,500), flooring ($500 to $1,500 for a small room), a laundry sink if desired ($400 to $1,000 installed), and finishing touches like shelving, paint, and trim ($500 to $1,500).

If you need to add plumbing from scratch — hot and cold water supply lines, a drain connection, and a washer drain box — the plumbing work alone runs $3,000 to $7,000 in Metro Vancouver. This involves cutting the concrete slab to connect to the existing drain stack, running new supply lines, and installing a proper P-trap and drain. If the basement drain is below the main sewer line (common in homes without a gravity-fed basement drain), you may need a sewage ejector pump at an additional $2,000 to $4,500 installed. The total for a laundry room build-out from scratch in an unfinished basement — including all plumbing, electrical, framing, insulation, drywall, flooring, and fixtures — runs $12,000 to $18,000.

Electrical requirements are straightforward but must be done properly. A washer needs a dedicated 20-amp, 120-volt circuit. An electric dryer requires a dedicated 30-amp, 240-volt circuit. A gas dryer needs a 120-volt outlet plus a gas line (gas line work requires a licensed gas fitter with Technical Safety BC certification). You will also want a dedicated circuit for the laundry room lighting and general-purpose outlets. All electrical work must be performed by a licensed electrical contractor and inspected by Technical Safety BC. Budget $1,500 to $3,000 for the electrical component.

Ventilation is a critical detail that gets overlooked in basement laundry rooms. The dryer vent must exhaust to the exterior — never into the basement space, which would dump warm, moisture-laden air into a below-grade environment and create severe mould problems in Vancouver's already humid climate. If the laundry room is in the centre of the basement, running the dryer vent to an exterior wall can be complex and may require routing through the ceiling or up through the floor above. Keep the vent run as short and straight as possible — every elbow and extra foot of ductwork reduces dryer efficiency and increases lint buildup. The BC Building Code requires the vent duct to be rigid or semi-rigid metal, not flexible vinyl.

Flooring choice matters in a basement laundry room. Water-resistant flooring is essential — washer hoses fail, drains can back up, and condensation drips. Porcelain tile ($9 to $20 per square foot installed) is the most durable and fully waterproof option. LVP ($4 to $9 per square foot installed) is a popular and more affordable choice that handles splashes well. Avoid laminate flooring, which swells and delaminates when exposed to standing water. Consider installing a floor drain if one does not already exist — it provides a safety outlet for washer overflows and costs $800 to $2,000 to add in a concrete slab.

A building permit is required from your local municipality for any new plumbing, electrical work, or framing. Plumbing must be done by a licensed plumber and inspected by the municipality. Budget $300 to $800 for permit fees on a laundry room project. Need help finding a contractor for your basement laundry room?
