How much does it cost to finish a basement in Etobicoke with a bathroom and kitchenette?

Finishing a basement in Etobicoke with a bathroom and kitchenette typically costs between $55,000 and $100,000 for an 800 to 1,200 square foot space, placing this squarely in the mid-range to high-end category of GTA basement renovations. The bathroom and kitchenette are the two most expensive components because they require plumbing work, which often means breaking and repairing the concrete floor, along with additional electrical circuits and ventilation.

Let's break this down into its major cost components. The base finishing — framing, insulation, vapour barrier, drywall, electrical, flooring, and paint — runs $35 to $50 per square foot for standard quality, so roughly $28,000 to $60,000 for the overall space. On top of that, a three-piece bathroom (toilet, sink, and shower) costs $15,000 to $30,000 if your Etobicoke home already has a plumbing rough-in, or $20,000 to $40,000 without one. If you want a four-piece bathroom with a bathtub, budget $20,000 to $50,000. The kitchenette — typically including a small counter with sink, cabinetry, under-counter fridge, microwave, and possibly a cooktop — costs $5,000 to $20,000 depending on finishes and the extent of plumbing and electrical work required.

Etobicoke's housing stock is diverse, ranging from 1940s and 1950s bungalows in areas like Long Branch and New Toronto to larger 1970s and 1980s homes in Rexdale and the Kingsway. Older homes near the lakefront face particular challenges — the water table is higher in these areas due to proximity to Lake Ontario, meaning your sump pump runs more frequently and waterproofing is absolutely critical before any finishing work. If you have any signs of moisture, budget an additional $5,000 to $25,000 for waterproofing before the renovation even begins.

The kitchenette brings some specific code and permit considerations. If you're installing a sink, you need proper drain and supply plumbing done by a licensed plumber. If you're adding a cooktop or oven, you'll need a dedicated electrical circuit — and if it's gas, you'll need a licensed gas fitter and a TSSA inspection. The ventilation requirements for a kitchenette include a range hood or exhaust fan vented to the exterior. Your bathroom will also need an exhaust fan vented to the exterior with a minimum 50 CFM capacity — never into the attic or soffit, which is a common and problematic shortcut.

One often-overlooked cost in a kitchen-and-bathroom basement renovation is your home's electrical panel capacity. Many Etobicoke homes built before the 1980s have 100-amp electrical service, and adding a bathroom and kitchenette with their dedicated circuits can push you past that capacity. An electrical panel upgrade to 200 amps costs $3,000 to $5,000 and must be done by an ESA-Licensed Electrical Contractor. Your electrical contractor will assess whether an upgrade is needed during the quoting process.

Don't forget the City of Toronto building permit at $1,500 to $4,000, separate ESA electrical permits, and plumbing permits. Budget a 10 to 15 percent contingency on top of all quoted costs — basements regularly reveal surprises once walls and floors are opened up. For a project of this scope in Etobicoke, you're looking at 8 to 14 weeks of construction time once permits are approved, and permit approval itself can take 4 to 8 weeks through the City of Toronto.
