What Goes Into a Bathroom Renovation That Lasts?
Bathrooms fail at the waterproofing, so that is where we start: Schluter-KERDI or Wedi systems, sloped mortar beds or linear drains, and uncoupling membranes under tile. Then come the finishes: floating vanities, wall-hung toilets, thermostatic valves and frameless glass from Kohler, Toto, Grohe and Rohl. Primary baths typically run $18K-$65K, powder rooms $12K-$35K and condo baths $15K-$55K.
The parts of a bathroom you never see decide how long it lasts:
- Membrane waterproofing on every shower wall and floor, flood-tested before tile.
- Uncoupling membrane (Schluter-DITRA) under floor tile so it does not crack as the house moves.
- Correct slope and drains, whether a centre drain on a mortar bed or a linear drain at the wall.
- Blocking in the walls for grab bars, glass, vanities and wall-hung toilets on Geberit carriers.
- Ducted exhaust vented outside, not into the attic.
Types of Bathroom Renovations
Primary ensuite
The biggest bathroom project in most homes. Curbless shower, double vanity, heated floor and often a freestanding tub. $18K-$65K depending on size and finishes.
Family bathroom
Durable finishes, a tub-shower combination or a walk-in shower, storage and easy-clean surfaces.
Powder room
Small room, big impact. Wall-hung toilet, a statement vanity, plaster or wallpaper and good lighting. $12K-$35K.
Condo bathroom
Fixed drain and riser locations, strict work hours and board approval. Large-format porcelain and linear drains make small condo baths feel bigger. $15K-$55K.
How Much Does a Bathroom Renovation Cost in Toronto?
| Bathroom | Tier 1 refresh | Tier 2 to the studs |
|---|---|---|
| Powder room | $12K-$20K | $20K-$35K |
| Family bath | $18K-$30K | $30K-$50K |
| Primary ensuite | $25K-$40K | $40K-$65K |
| Condo bath | $15K-$30K | $30K-$55K |
A Tier 1 refresh replaces tile, vanity and fixtures without moving drains. A Tier 2 renovation goes to the studs, moves plumbing where needed and rebuilds the shower from the framing out. For all tiers, see the Toronto renovation cost guide.
When Do You Need a Full Bathroom Renovation?
- Grout keeps cracking or tiles sound hollow when you tap them.
- There are stains on the ceiling below, or soft spots in the floor.
- The tub surround is a one-piece insert you want to replace with tile.
- You want a curbless shower for ageing in place.
- The fan does not clear steam, and paint is peeling.
Any of these usually means water has been getting where it should not, and a Tier 2 renovation is the safer choice.
Curbless Showers: Why They Need Planning
A curbless walk-in shower looks simple, but the floor must slope to the drain while staying level with the rest of the bathroom. That usually means recessing the subfloor between or across the joists, adding a linear drain and extending the waterproofing across the whole floor. In older Toronto homes we check joist size and direction on the site visit, then plan it into the framing. Done right, it is the most accessible and easiest-to-clean shower you can build.
Bathroom and Kitchen Together
Many clients renovate a bathroom at the same time as their kitchen or basement. Sharing design time, permits and trades usually saves money and weeks compared with separate projects, which is how we plan most home renovations in Toronto. Our Yorkville client did a condo kitchen and bath together for $128K, finished on the exact date promised.
