Bathroom Renovation in Toronto
Full remodels, wet rooms, and ensuite builds.
Space, slope and old cast iron are what make bathroom renovation in Toronto harder than the tile samples suggest. Many pre-war houses were built with a single bathroom upstairs, tucked under a sloping roof or over the kitchen, served by a cast-iron stack and supply lines patched for decades. Condo bathrooms bring the opposite problem: tidy rooms where the building's risers and rules set what can move.
Nexon Build handles full bathroom remodels, primary ensuites and new bathrooms in Toronto, with waterproofing, tile, plumbing, electrical and glass managed by one team on a fixed-price contract. Our Yonge Street bathroom, with its curbless walk-in shower and emerald feature wall, shows how we approach the details that decide whether a bathroom lasts: the subfloor, the membrane and the drain, long before the finishes.

Second-floor bathrooms in Toronto's older houses
Upstairs bathrooms in Victorian and Edwardian houses hide the most water damage. Decades of failed grout and leaking tub drains often leave joists soft or notched, and floors are rarely level. We open the floor, sister or replace damaged joists and re-level before waterproofing, because tile laid over a moving floor cracks. Old cast-iron stacks and galvanized lines are replaced back to sound pipe, and fans are ducted outdoors rather than into the attic, where moisture rots sheathing. Our guide to what old Toronto houses hide explains how we budget for it.
Curbless showers and waterproofing: the Yonge Street bathroom
Waterproofing is where a bathroom's durability lives, along with much of its cost. On our Yonge Street bathroom we built a curbless walk-in shower behind a glass screen, with a stacked emerald-tile feature wall, large-format stone-look tile and a walnut floating vanity. A curbless shower in an old house means recessing or sloping the subfloor so water drains without a curb, which takes joist work and careful detailing, not just a different tray.
A durable shower is waterproofed as a system: membrane, sealed penetrations and a correctly sloped drain, all before tile goes on the wall. Heated floors, new fans and lighting add circuits, so our licensed electrical contractor files an ESA notification for that work and ESA inspects it, separately from any plumbing permit. Glass enclosures go in last, once the tile has cured.
Condo bathroom remodels and ensuite renovation in Toronto
Condo bathrooms are compact, and the building controls the services. Drains and supplies connect to risers you can't move far, water shut-offs need the property manager, and many corporations require approved drawings and proof of insurance before demolition. In houses, an ensuite renovation often means converting a bedroom corner or closet, and adding new drains and supply lines is plumbing work that needs a permit. A basement bathroom also needs a plan for sewer backup, covered on our basement renovation in Toronto page.
Bathroom remodel costs and permits in Toronto
Our 2026 Toronto range is about $15,000 to $25,000 for a standard bathroom and $35,000 to $60,000+ for a primary ensuite with custom tile, heated floors and frameless glass. Tile labour and waterproofing account for much of the cost. Permits follow the plumbing: replacing a toilet, vanity or tub in place is exempt, while new or relocated drains need a building permit. The Toronto bathroom renovation cost guide has the detail, and our Toronto area page covers the City's process.

Common questions
Do I need a permit to renovate a bathroom in Toronto?+
Only if you change the plumbing system or the structure. The City exempts repairing and replacing plumbing fixtures, so swapping a vanity, toilet or tub in the same place needs no building permit. Moving a toilet, adding a shower drain, building a new bathroom or altering joists or walls does. Electrical work for heated floors or new lighting needs an ESA notification either way.
Can I put a curbless shower on the second floor of an old Toronto house?+
Often yes, but it's a structural job as much as a tile job. The floor under the shower has to drop or slope so water drains without a curb, which usually means modifying or reinforcing joists and sometimes adding blocking or headers. We check joist size, span and condition before committing to curbless, and confirm whether the structural change needs a permit.
What's different about renovating a bathroom in a Toronto condo?+
The building decides more than you do. You'll need the corporation's approval, usually with drawings and insurance details, and the property manager to shut off risers. Toilets and drains stay close to existing stacks, working hours follow the building's rules, and flooring often needs an approved acoustic underlay. We handle the submissions so the board's review doesn't delay the start.
How much does bathroom renovations cost in Toronto?+
A bathroom renovation in Toronto runs about $15,000–$25,000 for a standard bathroom, and $35,000–$60,000+ for a full primary ensuite with custom tile, heated floors, and frameless glass.

About $15,000–$25,000 for a standard bathroom, and $35,000–$60,000+ for a full primary ensuite with premium tile, heated floors, and glass.
How long does a bathroom renovation take?+
A standard bathroom renovation takes 3–5 weeks. A full primary ensuite build can take 6–10 weeks.
Why does waterproofing matter so much?+
It's what keeps water out of your framing and the rooms below for decades. We install proper membranes and inspect the waterproofing before any tile goes on — it's the step you never see but always rely on.
