Bathroom renovation timeline in Toronto: week by week

The overall picture

The single most common frustration we hear from homeowners who have renovated with other contractors is that the project took far longer than they were told. The honest answer to "how long will my bathroom take?" depends heavily on the scope — and most estimates undercount the time required for tile work and the lead times on fixtures and fittings.

As a reliable baseline: a standard bathroom renovation — a main bath or secondary ensuite with straightforward tile work and in-stock fixtures — runs 4 to 8 weeks from demo to completion. A large primary ensuite with custom tile patterns, a freestanding tub, a large-format shower, and a custom vanity is more realistically 8 to 14 weeks. If that number surprises you, read the tile section below — it will explain why.

These timelines assume permits where required, which is standard practice for any plumbing or electrical work. They also assume that all material selections are finalized and products are on site before demo begins. That last point is not a small assumption — it is one of the most important variables in whether your project finishes on time.

Why tile takes longer than people expect

Tile work is the reason bathroom renovations take as long as they do, and it is the phase most commonly underestimated by homeowners — and, frankly, by some contractors. Understanding why it takes time will help you plan more accurately and recognize when a quote is unrealistically fast.

Several factors compound to make tile installation inherently time-intensive:

• Large-format tiles require more precision. A 24x48" porcelain slab is far less forgiving than a 4x4" ceramic tile. The substrate must be absolutely flat — any variation over the tile's surface will cause lippage (one edge sitting higher than the next). This means more time on floor and wall prep, and more precise back-buttering to ensure full coverage behind each piece.
• Custom patterns multiply labour. A herringbone, chevron, or stacked vertical pattern requires cutting at angles, careful alignment, and significantly more cuts per square foot than a running bond or grid layout. What looks like a modest bathroom can take three to four times as long to tile as a simpler layout would suggest.
• Grout requires 72 hours to cure before sealing. This is not a step you can rush. Sealing grout before it has fully cured traps moisture and leads to efflorescence, cracking, and premature failure. In practice, this means that after the tile work is complete, the bathroom cannot be finished for at least three days.
• Natural stone requires sealing before and after grouting. If you are using marble, travertine, slate, or another natural stone, the sealing process adds additional time and cannot be skipped.

Week-by-week breakdown

The following timeline applies to a mid-complexity bathroom: a 60–90 sq ft space with a tiled shower, new flooring, new vanity and toilet, and a glass shower enclosure. Adjust the tile phase upward for more complex scopes.

Week 1 — Demo and discovery

Demolition is satisfying to watch and relatively quick to execute, but it is also the moment of truth for every bathroom renovation. Once the tile comes off the walls and the drywall or cement board is exposed, you find out what has been happening behind the surfaces for the past 20, 30, or 50 years.

Common discoveries during demo include:

• Failed or absent waterproofing — moisture damage to framing behind the shower that must be remediated before proceeding
• Cast iron drain stacks or supply lines that are corroded, scaled, or sized below current code, requiring replacement
• Electrical that is undersized, improperly grounded, or missing the GFCI protection required by code in wet areas
• Mould in wall cavities that requires proper remediation and drying time before enclosure

A good contractor frames these discoveries as information, not a problem, and addresses them methodically. The risk of skipping remediation to "save time" is a bathroom that fails again within a few years — often in a more expensive way.

Week 2 — Rough-in plumbing and electrical

With the walls open, your plumber and electrician do their rough-in work: repositioning drain locations if the layout is changing, running new supply lines, installing the shower valve rough-in, and running electrical for exhaust fan, lighting, heated floor if specified, and any in-floor heating thermostat. This is also when the city inspection for rough-in work is booked and completed.

Inspection timing is worth noting: Toronto and GTA municipalities vary in inspector availability. In some jurisdictions rough-in inspections can be booked within a day or two; in others you are waiting a week. This is a genuine schedule variable outside the contractor's control, and it can idle the project while you wait. An experienced contractor books the inspection as early as possible and sequences other preparatory work to fill the gap.

Weeks 2–3 — Cement board substrate and waterproofing membrane

This phase is invisible once the tile goes on, which is exactly why it matters so much. The cement board substrate provides the rigid, stable, moisture-resistant surface that tile needs to adhere properly over the long term. Standard drywall behind tile — still seen in older renovations and some budget builds — will absorb moisture, soften, and eventually cause tile failure.

Over the cement board, a full waterproofing membrane is applied to the entire shower enclosure: walls, floor, and critically, the seams and corners where water is most likely to find its way through. The industry standard systems — Schluter KERDI, Wedi, or equivalent — are bonded membranes that form a continuous waterproof layer. These systems cannot be rushed: the membrane must be installed correctly with proper overlap at seams and full coverage at transitions, and it needs to cure fully before tile begins.

Do not let any contractor skip or abbreviate this phase. A bathroom that leaks into the floor assembly or adjacent wall cavity is one of the most expensive renovation failures you can encounter — and it is entirely preventable with proper waterproofing executed correctly the first time.

Weeks 3–5 — Tile installation

This is the longest single phase of the renovation, and for good reason. Tile installation is slow, precise, physical work. Shower walls typically come before the floor to allow for proper height setting of floor tile. Each area — shower floor, shower walls, main floor, any feature walls — is a separate sequence of layout, cutting, setting, and curing time before grouting can begin.

For a primary ensuite with a large shower, feature wall, and custom floor pattern, five weeks is not unusual for the tile phase alone. A simpler main bath with subway tile and straightforward floor tile can complete tile work in one and a half to two weeks. The range is genuinely wide, and any contractor who quotes a flat two weeks for all tile work without knowing your specific selections and layout is guessing.

Weeks 5–6 — Vanity, fixtures, and glass enclosure installation

With tile complete and grout sealed, the bathroom starts to look finished very quickly. The vanity is set and plumbed, the toilet is installed, the shower valve trim is fitted, towel bars and accessories go in, the mirror is hung, and lighting is connected. For heated floors, the thermostat is wired and programmed.

The glass shower enclosure is the notable exception to the "things happen fast now" feeling of this week. The glass enclosure cannot be measured until tile is complete — the measurement must be taken off the finished tile surface, not off drawings. Once measured, a custom-cut frameless or semi-frameless enclosure typically has a 3–4 week fabrication and delivery lead time. This is why the glass needs to be ordered immediately after tile is complete, and why the overall project timeline accounts for this lead time rather than treating it as a surprise.

Weeks 6–7 — Punch list, paint, trim, and final clean

The final week covers touch-up paint on walls and ceiling, installation of door trim and baseboard if disturbed during demo, caulking at all tile-to-fixture junctions (tub deck, toilet base, vanity backsplash), and a professional clean. A thorough punch list walkthrough with the client identifies any remaining items — a grout line that needs touching up, a fixture that needs adjustment — and these are resolved before the project is considered complete.

What causes bathroom renovations to overrun

Most bathroom renovation delays fall into a small number of predictable categories, all of which are avoidable with proper planning:

• Tile backordered or discontinued. The tile you selected at the showroom is not always immediately available. Tile ordered from overseas suppliers can take 6–10 weeks to arrive. If you finalize your tile selection after demo begins, you are potentially waiting weeks with an unusable bathroom for a container to arrive.
• Custom vanity lead time. Custom cabinetry for a vanity — any vanity that is not a standard stocked unit — typically requires 6–12 weeks from order to delivery. If the vanity is ordered after demo, you are adding months to the timeline. Order it the moment the design is finalized, before a single tile is touched.
• Glass shower enclosure lead time. As noted above, 3–4 weeks from measure to installation. The measurement cannot happen until tile is complete. This is not something you can accelerate — it is a fixed lead time with the fabricator. Plan for it from day one.
• Plumbing surprises behind the walls. Old cast iron drain stacks that need sectional or full replacement, supply lines in copper that have pinholed, blocked venting — these are not rare in Toronto's older housing stock. Discovery during demo adds time that cannot be compressed.
• City inspector availability. This is outside the contractor's control, but an experienced contractor builds it into the schedule rather than treating it as an unexpected event.

How to prevent delays: the selections rule

The single most effective thing you can do to keep a bathroom renovation on schedule is to finalize every single selection before demolition begins. Every tile, every fixture, every accessory, the vanity, the mirror, the lighting — all of it.

This sounds obvious but is regularly ignored. Homeowners often treat the renovation start date as the beginning of the selection process. In practice, selections should be complete and products should be ordered 6–8 weeks before demo. This gives time for overseas tile to arrive, for the custom vanity to be fabricated, and for any discontinued or backordered items to be identified and substituted before they become schedule problems.

• Finalize all tile, fixtures, and fittings at least 6–8 weeks before demo
• Order the custom vanity the moment the design is signed off
• Have the glass shower enclosure measured immediately after tile installation is complete, and order it the same day
• Confirm stock availability on all specified products before demo begins — discontinued items discovered mid-project cause the worst delays

Managing without a bathroom during the renovation

If the bathroom being renovated is your only bathroom, sequencing matters enormously. A contractor who understands this will prioritize getting a functioning toilet restored within the first few days of rough-in plumbing — not a finished bathroom, but at minimum a toilet connected and operational while the rest of the work proceeds.

Full restoration of a functioning bathroom — shower or tub, sink, toilet — comes after tile is set and cured, which means there is typically a period of one to three weeks where you will need to make other arrangements. This is worth discussing explicitly with your contractor before the project begins so the sequencing is planned around your household's needs, not treated as an afterthought.

Kopman Build's approach to scheduling

At Kopman Build, we do not start a bathroom renovation until all selections are finalized and key long-lead items are ordered. It is a non-negotiable part of how we run projects, and it is the main reason our bathrooms finish on time. We track inspector bookings, glass lead times, and delivery windows from the beginning of the project — not as reactive firefighting, but as a standard part of project management.
