Bathroom Renovation Cost in Markham: 2026 Price Guide

Budget $15,000–$30,000 for a full bathroom renovation in Markham as of 2026. Most standard full-scope projects land between $16,000 and $24,000 — that covers demolition, new waterproofing, porcelain tile, a new tub or shower, vanity, toilet, and lighting, all within the existing layout.

Around that core number:

• Powder room: $6,000–$12,000
• Standard 3-piece family bathroom: $15,000–$30,000
• Primary ensuite: $28,000–$45,000 typical; $35,000–$75,000+ with a walk-in shower, freestanding tub, and double vanity
• Luxury rebuilds with layout changes: $50,000–$70,000+

Per square foot, GTA bathrooms run $250–$450, and Toronto-area pricing overall sits about 15–20% above the Ontario average. Two comparison rules before you sign anything: confirm whether 13% HST is included, and confirm whether the price assumes plumbing stays where it is — moving a toilet or tub drain adds $2,000–$6,000. Our bathroom renovation cost guide lays out the full line-item breakdown.

The refresh tier, $8,000–$15,000, is cosmetic: new vanity, toilet, lighting, paint, maybe a tub refit — over existing, intact waterproofing. It suits a Cornell or Greensborough bathroom from the 2000s that works fine but looks like the year it was built.

The full renovation tier, $15,000–$30,000, takes the room to the studs and replaces the parts you cannot see — the waterproofing membrane, the substrate, the valve — along with everything you can. Original bathrooms in Milliken and Armadale homes from the 1980s–90s are squarely in this territory. So are 1960s–70s Thornhill bathrooms, usually with extra line items we cover below.

The rebuild tier, $30,000–$50,000+, changes the room: tub-and-stall becomes an oversized walk-in shower, single vanities become doubles, heated floors go in at $1,500–$3,000 and frameless glass at $2,000–$4,000. Markham's larger two-storey homes from the 1990s and 2000s were built with ensuites smaller than their bedrooms deserved, which is why this tier is our most quoted in Berczy and Unionville-area streets.

Markham's renovation budgets track its building eras closely.

Thornhill's Markham side built up through the 1960s and 70s, which puts it inside both the aluminum wiring window (1965–1976) and the asbestos-era finish window. Aluminum is insurable once copper pigtailing is done under an ESA permit; asbestos in drywall compound or vinyl flooring is a test-before-demolition situation ($300–$800 for lab work). Neither is a reason to panic — both are reasons to carry a proper contingency.

The historic cores around Unionville Main Street and Markham Village are older still. Renovating a bathroom in a century home means plaster walls, possible galvanized plumbing, and framing that predates modern fixture weights — all workable, all worth pricing honestly rather than optimistically.

Milliken and Armadale (1980s–90s) and the newer communities — Berczy, Cornell, Greensborough, Cathedraltown — are largely free of hazmat history. The one check we always run in 1995–2007 builds and condos: Kitec plumbing, the orange-and-blue piping with brass fittings. Its class-action claims window has closed, remediation is out-of-pocket, and insurers ask — so if it is in your walls, replace it while they are open.

Labour runs about a third of the total; materials and their installation take the rest.

Tile is the anchor. Standard porcelain installs at $10–$25 per square foot, while large-format porcelain, natural stone, and marble start around $40. A full bathroom tiling package typically costs $2,500–$8,000, with tile setters billing $80–$125 per hour — and patterns like herringbone earning the top of that range.

The supporting lines at mid-range pricing: vanity with countertop $1,500–$3,500 installed; shower or tub package $2,500–$5,000; plumbing rough-in and connections $3,000–$5,000; electrical and lighting $1,500–$3,000; frameless glass $2,000–$4,000.

This is also where quotes diverge. One contractor prices a $12 tile with standard waterproofing; another prices a $45 stone with a full membrane system and in-floor heat. Both can honestly call it a bathroom renovation and land $15,000 apart. Why renovation quotes vary so much between contractors is mostly a story about scope and specification — insist on itemized bids so you are comparing the same room.

Markham applies the standard Ontario Building Code tests. No permit for like-for-like work: new fixtures in existing locations, tile, paint. A City of Markham building permit is required when plumbing moves or is added, structure changes, or a new bathroom is created — and complete residential applications run on the province's legislated 10-business-day first review, with real-world timelines depending on drawing quality. Electrical work sits outside the municipal permit entirely: your licensed electrical contractor files an ESA notification, typically $90–$300.

Beyond permits, the quiet multipliers deserve room in the budget: plumbing relocation at $2,000–$6,000, layout changes at $2,000–$5,000, hazmat handling in pre-1990 Thornhill homes, and Kitec replacement in 1995–2007 builds. Then there are the costs nobody itemizes — dumpster and disposal, parking, protection of finished floors, design time. Our rundown of the hidden soft costs in a renovation covers the lines that surprise first-time renovators most. A good contract shows all of them before work starts, not after.

Let the house set the contingency. Berczy, Cornell, Greensborough, Cathedraltown: 10% on top of your base budget is normally enough. Milliken and Armadale: 10–15%. Thornhill's 1960s–70s streets and the Unionville and Markham Village historic cores: 15–20%, because era-related discoveries are likelier and worth fixing properly while walls are open.

Choose the refresh tier only when the waterproofing is known-good and recent. Choose the full renovation when the bathroom is 20+ years old or showing water signs — hollow tiles, persistent damp grout, soft spots near the tub. Choose the rebuild when the layout, not the finishes, is what fails you every morning.
