Bathroom renovation options and costs in Markham
Bathroom renovations in Markham typically fall into a few clear categories, and your choice of scope is what most strongly drives price. Markham’s housing mix matters: about 18.5% of homes in the area were built before 1981, which often means older drain layouts, dated venting, and finish materials that may conceal asbestos-containing components in certain floor or wall products. On top of that, Markham has a large share of homeowners—90,545 homeowner households (81.7% of households own)—so there’s steady demand for longer-term upgrades like better waterproofing, upgraded exhaust, and modern plumbing fixtures.
In the Toronto market, costs are shaped less by “weatherproofing the bathroom” and more by labour intensity and the reality of opening walls and floors in older homes. Skilled trades in the GTA command premium hourly rates, and work like tiling, custom shower builds, and plumbing rerouting is time-consuming. Toronto-area homes built in the post-war to 1980-era window can also require bringing drainage/venting and shut-offs up to current Ontario code when lines are disturbed. That’s why a project that looks similar on paper can land in very different budgets once contractors confirm hidden conditions.
In practice, the busiest renovation activity is commonly around established neighbourhoods in Markham such as Unionville, where older homes are frequently updated for comfort and resale. Use the table below to line up typical options with realistic GTA pricing, then you can compare quotes apples-to-apples before you commit.

What affects the price of bathroom renovation in Markham
Even when homeowners describe the “same bathroom,” quotes in the Toronto economic region can vary by 30–50%. The main reasons aren’t cosmetic choices—they’re labour rate differences, how much demolition is needed, and what hidden issues appear once walls are open. In Markham, older housing stock is a bigger driver than climate alone: when work starts in homes from earlier eras (including the 18.5% built before 1981), contractors may find cast-iron or undersized drain components, dated copper supply lines, and ventilation that’s insufficient for modern moisture loads.
Toronto-area labour is also premium, and bathroom work is inherently labour-intensive. Tiling, custom waterproofing details, and plumbing rough-in take more hours than many homeowners expect. That’s why an “average” full renovation commonly sits in the $12,000–$30,000 band for Markham, with complex plumbing or electrical updates pushing toward the upper end. In real builds, discovery of asbestos-containing materials—such as in some older vinyl floor tiles or legacy drywall compounds—can trigger abatement requirements and add $1,500–$5,000+ to the budget, depending on scope and access.
Here are a few local examples of cost swings in Markham: (1) If you move the vanity and require drain reconfiguration, you may add significant rough-in and backfill labour before tiling can restart; (2) switching from standard ceramic to large-format porcelain can raise material cost and increase labour due to layout and flatness requirements; (3) adding a second shower head or relocating the valve can force additional plumbing work. Conversely, keeping the existing layout and using straightforward finishes can keep you closer to the mid-range end of the $12,000–$20,000 range.
| Price Factor |
Why It Matters |
Cost Impact |
| Layout change — moving drain or supply lines |
Requires rough-in work, patching, and often more framing and floor prep |
Typically adds several thousand dollars depending on distance and access |
| Tile selection — large-format porcelain vs. mosaic vs. ceramic |
Large tiles require a flatter substrate and more precise setting; mosaics are labour-heavy |
Often shifts the job by a mid-range to high-end difference in labour and materials |
| Fixture tier — builder-grade vs. mid-range vs. designer brands |
Higher-tier trims and valves can require specific installs and upcharge for compatibility |
Can add hundreds to a few thousand dollars, especially with premium valves and glass |
| Subfloor condition — rot or unlevel concrete adds scope |
Unlevel floors demand additional underlayment and patching before tile can be installed |
May add material plus labour and extend the schedule |
| Electrical — adding GFCI outlets, exhaust fan, heated floor circuit |
Baths require upgraded safety and proper circuit protection; heated floors add wiring and controls |
Commonly adds to labour and permit-related tasks; heated floors cost more than a fan swap |
| Waterproofing method — membrane type and extent |
Better systems require proper prep, full coverage, and compatible thinset/thickness planning |
Usually increases material cost but reduces long-term moisture risk |
| Older-home surprises — asbestos tile, cast-iron drains, galvanized pipes |
Discovery can change the entire work plan and require licensed remediation |
Can add $1,500–$5,000+ or more depending on what’s found and how much is removed |
| Bathroom size — sq ft drives tile and labour time directly |
More square footage increases tile setting, grout lines, waterproofing area, and cleanup |
Increases cost roughly proportionate to surface area and time |
Permits & regulations in Ontario
In Ontario, many bathroom updates are treated as “finishes-only” work, which typically means no permit is required. For example, swapping fixtures like a toilet, vanity, or mirror, retiling surfaces without altering plumbing routes, replacing a like-for-like tub trim, and repainting are usually not permit-triggering. However, several common renovation steps do require a permit—especially when you change the plumbing or add new electrical components. In practice, Markham homeowners should expect permits/inspections when there’s (1) relocation of plumbing—moving drains or water supply lines, modifying rough-in, or changing shut-offs; (2) new exhaust fan venting that requires electrical work and/or vent modifications; and (3) any structural wall changes or opening that affects framing or load paths.
Electrical work must meet Ontario code and be performed by a licensed electrician. Steps that typically require a licensed electrician include adding or relocating a GFCI-protected outlet, installing a new exhaust fanheated floor
To verify a contractor in Markham, ask for: (1) their Ontario trade licence details (and confirm it’s active via the appropriate online registry or the contractor’s documentation), (2) a current certificate of insurance showing liability coverage, and (3) proof of workers’ compensation coverage—often shown as WSIB/WCB clearance or registration documentation. Ensure the certificate matches the contractor’s legal name and address, and keep copies for your records before work starts.
Choosing tile, waterproofing and fixtures for your Markham bathroom
In Markham, three material decisions consistently shape your budget: tile choice, waterproofing system, and fixture tier. First, tile. Entry-level ceramic tile can be a cost-effective way to refresh a tub surround, but it’s often more forgiving on patterning and less expensive than porcelain. Porcelain tile is denser and typically performs better for floors, but it can require more careful substrate prep and layout. Natural stone (marble, travertine, slate) looks premium but tends to involve higher material cost, more specialized finishing (sealing/maintenance), and careful install to avoid unevenness or staining.
Second, waterproofing. Ontario bathrooms see frequent moisture from showers and humid air, and the wrong system is a common cause of grout failure and mould. A paint-on membrane can work for some situations, but wet-area success depends on proper prep and coverage. Bonded sheet membranes or well-installed systems (including modern engineered approaches) often provide more robust protection, especially for shower floors and walls with higher tile loads.
Third, fixtures. Builder-grade taps and trims cost less upfront, while mid-range and designer brands often deliver better valve performance, finishes, and longevity—plus they may simplify maintenance. If resale is a goal in Markham’s homeowner-heavy market (81.7% own), choosing a solid mid-range fixture tier is often the sweet spot.
Example: upgrading a standard tub surround to full-height porcelain with a premium waterproofing method might move you toward the mid-to-upper end of the $12,000–$30,000 full-renovation band. But if you skip waterproofing quality to “save a few thousand,” you can lose that value quickly when cracks or moisture issues appear.

How to choose a bathroom renovation contractor in Markham
Choosing a bathroom contractor in Markham should start with verification and then move to written clarity. For licensing, request the contractor’s Ontario trade licence information and confirm it’s active (don’t rely on a photo taken last year). For liability, ask for a certificate of insurance that lists the contractor’s legal business name and includes sufficient coverage for renovation work. For workers’ compensation, ask for WSIB/WCB clearance documentation—this matters because you don’t want the project sitting in limbo if a subcontractor isn’t properly covered.
Next, get 2–3 itemised written quotes—not a single lump-sum number. You want a breakdown that separates labour for demo, framing/patching, tile setting, waterproofing, electrical/plumbing allowances, disposal, and materials. Carefully review what’s excluded: for example, does the quote include permit pulling, if required, and municipal inspection costs? Is asbestos abatement included only if discovered, or is there an allowance? Confirm whether waste removal and dump fees are included.
Then compare warranty terms. A workmanship warranty should specify length and coverage (often tied to waterproofing/tile performance). Product warranties may be provided by manufacturers; ask whether they’re transferable to you if you sell. Finally, payment schedules should be controlled—never pay more than about 10–15% upfront. Use a holdback until the job is complete and deficiencies are corrected, and ensure the start date and completion estimate are in writing so schedule slips are documented.
- Verify Ontario licence details before deposit; confirm it matches the legal business name on invoices.
- Request liability insurance and confirm dates and coverage limits on the certificate.
- Confirm WSIB/WCB clearance for the contractor (and that subs are covered).
- Demand itemised labour and materials: tile, thinset, waterproofing, fixtures, and glass hardware.
- Check whether disposal/dump fees are included in the quote price.
- Clarify permit responsibility: who pulls permits and who pays the fees.
- Ask how asbestos/old-material discoveries are handled and whether there’s an allowance.
- Confirm waterproofing scope (wet-area coverage, membrane type, and how seams are treated).
- Require a written start date and a realistic completion window.
- Get fixture/model numbers (not “or equivalent”) so you can compare like-for-like.
- Review warranty length for workmanship and products; ask if warranties are transferable.
- Use staged payments tied to milestones; keep a holdback until close-out items are finished.
Red flags in Markham include contractors who won’t provide proof of insurance or WSIB/WCB, quotes that are not itemised (especially for waterproofing and electrical), vague scope statements like “tile and finish” without specs, promises of “no permit required” when plumbing/electrical is being changed, and payment requests that exceed 10–15% upfront without a signed agreement and schedule.
Frequently asked questions — bathroom renovation in Markham
Do I need waterproofing behind the tile?
In most Markham bathrooms, yes—waterproofing behind the tile is strongly recommended, especially in tub/shower surrounds and any wet-area wall. The reason is simple: steam, soap residue, and repeated wet-dry cycles can drive moisture behind grout if the system isn’t designed to be water-resistant at the wall plane. For a typical full renovation, waterproofing is usually part of the mid-range scope that sits around $12,000–$20,000 in the GTA, and it’s also common in the higher-end builds. In older Markham homes (including those built before 1981), you may also uncover weak substrates, so a contractor should address prep and sealing details—not just add tile.
How do I compare bathroom renovation quotes?
Start by comparing quotes line-by-line, not just the final number. In Markham, the biggest differences usually come from labour scope (demo, framing/patching, tile setting), waterproofing method, and plumbing/electrical allowances once walls are opened. Ask each contractor to list the waterproofing system, tile type (ceramic vs porcelain), fixture models, and whether disposal and any permit handling are included. If one quote is near $12,000–$30,000 but another is much lower, check whether it’s missing essential items like exhaust fan electrical, GFCI provisions, waterproofing extent, or drain/vent rework allowances. Only compare “apples to apples” after you confirm specifications and inclusions.
Can I live at home during a bathroom renovation in Markham?
Sometimes yes, but it depends on how disruptive your chosen scope is. A cosmetic refresh (paint/fixtures/accessories) is often manageable without fully shutting down the home, but a full renovation usually requires wall and floor opening, plus drying time for waterproofing and tile set. In Markham, many homeowners choose a “partially live-in” approach: the crew may work on the bathroom while another bathroom remains functional, or there’s temporary access to plumbing for a short phase. If you’re converting a tub to a walk-in shower, expect the project to run closer to the 2–3 week window and plan around potential water shutoffs. Your contractor should provide a written schedule and explain how they’ll maintain safety and debris control.
What's the best bathtub material for a Markham home?
For most Markham homeowners, acrylic tubs are a practical choice because they’re relatively lightweight, clean well, and install efficiently. If your renovation is a “bath replacement” without major layout changes, bathtub replacements often sit around the $1,200–$3,500 band for materials and basic install, with more for surround work and waterproofing upgrades. If you’re dealing with an older layout or substrate issues, your contractor may recommend more robust underlayment and proper waterproofing at the tub surround to protect against moisture. If you’re converting to a shower, the best “material” is usually the shower pan system and waterproofing detail—not just the fixtures—because it’s the wet-area assembly that determines long-term performance.
Is it worth renovating a bathroom before selling in Markham?
Often, yes—especially if your bathroom is outdated, poorly ventilated, or shows signs of moisture damage. Markham’s large homeowner base means buyer expectations commonly include modern waterproofing, updated fixtures, and an exhaust fan that actually clears humidity. That said, the return depends on whether you upgrade the right items without overspending on luxury finishes that don’t match nearby comps. A mid-range full renovation (commonly in the $12,000–$20,000 range) tends to be the safest “value-focused” option because it updates core systems and finishes. If your home has older plumbing or possible hidden issues, spending on correct waterproofing and code-ready rough-ins usually improves buyer confidence more than high-end decorative upgrades alone.
How do I plan a bathroom renovation on a tight budget in Markham?
Plan by narrowing scope first, then choosing the right “budget wins.” If you’re tight on funds, consider keeping the layout and focusing on finishes that deliver impact: fresh tile in the wet area, a new vanity/lighting, and a reliable exhaust fan upgrade. Conversions and rerouting are where budgets blow up because they add rough-in and electrical/plumbing labour, especially in older homes where drain or vent work may be needed. A cosmetic refresh can start lower than a full reno, but for durable results aim for correct waterproofing and proper substrate prep. As a benchmark, full renos in Markham often land between $12,000–$30,000, so your strategy is usually “stay closer to the mid-range” by limiting layout changes and selecting mid-range fixtures while still paying for quality waterproofing and workmanship.
