How Long Does a Bathroom Remodel Take? Realistic Timeline

The planning and procurement phase is the most variable and most commonly underestimated part of a Canadian bathroom renovation timeline. It begins the moment you decide to renovate and ends when your contractor starts demolition. Everything in between - finalising the design, selecting and ordering all materials, applying for permits, and scheduling your trades - must be completed before a single wall is opened.

Material lead times are the primary variable in Canadian markets in 2025-2026. Standard tile from Canadian suppliers like Centura, Olympia Tile, and Tile Town is typically in stock and available in one to two weeks. But vanities with specific finishes, frameless glass shower enclosures (custom sizes), rainfall shower fixtures, and specialty items like zellige tile or apron-front bathroom sinks can run four to twelve weeks from order to delivery. Ordering these items before confirming your contractor start date - and building your start date around the longest lead-time item - is the single most effective timeline management action a homeowner can take.

Demolition is the fastest phase and the one that most frequently reveals surprises. A standard full bathroom gut - removing tile from floors and walls, pulling the vanity, toilet, and tub, and stripping walls to studs - takes one to two days for an experienced crew. A cosmetic-only renovation with no tile removal is measured in hours. The speed is real; the surprises that demolition uncovers are also real.

In Canadian homes built before 1985, demolition is the point at which asbestos-containing materials (floor tile backing, pipe insulation, ceiling texture) may be discovered. In Ontario, British Columbia, and Alberta, any asbestos-containing material discovered during a renovation must be managed by a licensed asbestos abatement contractor - the general contractor cannot proceed with demolition of that material. An asbestos assessment adds $300-$800 CAD, and remediation (if required) adds $1,500-$5,000+ CAD and typically one to two weeks to the timeline. Mould in wall cavities (common in Canadian bathrooms with inadequate exhaust ventilation) is the second most common demolition discovery, adding similar remediation time and cost.

Rough plumbing is the work your plumber does before walls close: repositioning supply lines (hot and cold), relocating the drain stack connection if the toilet or shower is moving, roughing in the new shower valve position, and running any new supply to a walk-in shower ceiling mount or second shower position. This work must be completed and inspected before tile backer goes up - plumbing buried behind closed walls without a rough inspection is a building code violation in all Canadian provinces.

The duration depends entirely on how much the layout is changing. A renovation where every fixture stays in its existing location requires only supply and drain reconnection - typically one day of plumber time. A renovation that includes a walk-in shower conversion (tub removed, new drain location, new shower valve supply rough-in) or any fixture relocation runs two to three days of plumber time for the rough-in alone, with a separate service call for fixture connection after tile is complete. Plumbers in most Canadian urban markets (Toronto, Vancouver, Calgary) bill at $100-$175 CAD per hour - the total plumbing labour cost is a function of hours worked, which is directly tied to the amount of layout change.

Rough electrical in a bathroom renovation covers installing or upgrading the exhaust fan wiring, running the GFCI circuit for vanity outlets, positioning lighting boxes at the correct locations above or beside the mirror, and - if in-floor radiant heating is in scope - running the 120V or 240V circuit for the heating mat and thermostat. In Canada, all electrical work in a bathroom must be performed by a licensed electrician, and all bathroom outlets within 1.5 metres of a water source must be on a GFCI (ground fault circuit interrupter) protected circuit under the Canadian Electrical Code.

A standard bathroom electrical rough-in for a renovation without significant changes (same outlet positions, same lighting locations, upgraded exhaust fan) takes half a day to a full day of electrician time. A renovation that adds a dedicated circuit for a steam shower generator, relocates the vanity lighting position, or installs in-floor heating with a new 240V circuit runs one to two days of electrician work. The electrician returns for a second visit after drywall and tile are complete to install the vanity light fixture, outlet covers, switch plates, exhaust fan unit, and thermostat.

The rough inspection is a mandatory visit from the municipal building inspector to confirm that the rough plumbing and electrical work meets Canadian code requirements before the walls are closed with drywall or tile backer. In most Canadian municipalities, this inspection must be booked through the building department portal, with availability typically running one to three business days from the booking date. An experienced contractor books the rough inspection as soon as the rough work is substantially complete - a contractor who waits until the morning of completion to book the inspection adds unnecessary days to the timeline.

If the inspector identifies deficiencies (a plumbing pressure test failure, a missing GFCI circuit, or an electrical box at the wrong height), the deficiency must be corrected and a re-inspection booked - which adds another one to three day wait. Most deficiencies on a professionally executed rough-in are minor and correctable in hours; the re-inspection wait is the time cost. Once the rough inspection passes, walls can close and tile work can begin.

After the rough inspection passes, walls close with cement board (or moisture-resistant drywall in low-splash zones), and the tile setter installs the waterproofing system before any tile goes up. This is the most technically critical phase in the renovation - a waterproofing membrane failure discovered years later is far more expensive to remediate than the cost of doing this correctly the first time. The Schluter Kerdi system, Laticrete Hydro Ban, or equivalent membrane must cover all shower surfaces - floor, all four walls to the full tile height, and the inside of any recessed niche - before a single tile is set.

If the shower floor is curbless, the floor substrate must be sloped during this phase - the mortar bed or self-levelling compound is applied at the required ¼-inch-per-foot slope toward the drain before the waterproofing membrane goes down. This slope must be set correctly before the membrane is applied, because it cannot be adjusted after. On existing Canadian wood subfloors (common in all pre-2000 construction), a self-levelling compound application is typically required to bring the floor to the flatness tolerance required for large-format tile - this adds one day to the substrate phase and must fully cure (typically 24 hours minimum) before tile begins.

Tile installation is the longest single phase of a bathroom renovation and the one most subject to quality variation between tile setters. The duration depends on the total tile area, the complexity of the pattern, and the tile format - a bathroom with a herringbone feature wall, a mosaic shower floor, and large-format field tile takes significantly longer than one with straight-set subway tile throughout. A standard 5×8 bathroom with a tub-shower surround and a tile floor typically runs four to six days of tile setter time from first tile to finished grout. A larger bathroom with a walk-in shower enclosure, floor-to-ceiling tile on multiple walls, and a built-in niche runs seven to ten days.

The cure times embedded in this phase are the most commonly rushed steps in Canadian bathroom renovations - often at the insistence of homeowners eager to get their bathroom back, and sometimes at the decision of contractors managing tight schedules. Thinset adhesive must cure for a minimum of 24 hours (48 hours for large-format tile) before grout is applied. Grout must cure for a minimum of 72 hours before the shower is used with water. Sealing must be applied to natural stone or cement grout after full cure and before first use. Rushing any of these three steps produces grout failure, adhesive failure, or staining - all of which require expensive remediation.

Once tile is fully cured and grouted, the bathroom comes together quickly. The plumber returns to connect the vanity supply lines and drain, install the faucet, set the toilet, connect the shower valve trim and showerhead, and make final connections. The electrician returns to install the vanity light fixture, outlet covers, switch plates, and exhaust fan unit. The GC or carpenter installs the vanity cabinet, mirror, towel bars, toilet paper holder, and any other accessories. Paint touch-ups, caulking at all tile-to-fixture transitions, and final cleaning round out the phase.

This phase is where the "it's almost done" feeling collides with the reality that the last 20% of a renovation takes 40% of the coordination. The plumber and electrician each need a separate service call - scheduling them in the correct sequence (plumber first to set the vanity and toilet, electrician to wire fixtures that require cabinet or wall access, plumber again if any connections need adjustment after cabinet installation) requires active project management. A GC handles this coordination as part of their fee; a homeowner acting as their own GC must manage it directly.

The final inspection is a return visit from the municipal building inspector to confirm the completed work matches the approved permit scope and meets all applicable codes - plumbing, electrical, ventilation, and structural. The exhaust fan CFM rating is verified against code minimum (50 CFM for a bathroom, 100 CFM for a combined bathroom-toilet room in most Canadian provinces). GFCI outlet protection is tested. The plumbing connections are checked for leaks. Once the inspector signs off, the permit is closed and the renovation is formally complete.

A permit that is never closed - because the homeowner skips the final inspection - creates a disclosure obligation when the home is sold and can trigger complications with home insurance if a claim arises related to the renovation work. The final inspection costs nothing beyond the permit fee already paid and takes 30-60 minutes of the inspector's time. It is the step most commonly skipped and the one that creates the most legal and financial risk when it's absent.
