Typical bathroom renovation costs in Ontario
Bathroom renovation costs in Ontario vary significantly based on the size of the space, scope of work, materials chosen, and what gets discovered once the walls come open. These are realistic ranges from actual project experience — not marketing numbers designed to get you to call.
New fixtures, vanity, toilet, and paint. Updates the look and function without touching tile, plumbing, or layout.
New tile, shower or tub replacement, vanity, and flooring. Full cosmetic overhaul with some plumbing work — the most common type of bathroom renovation.
Complete strip-out, new layout, custom tile, all new fixtures. Everything is replaced; often includes waterproofing and plumbing relocations.
Converting a bedroom or closet space into a new bathroom. Involves new plumbing rough-in, framing, electrical, and full finishing.
Factors that drive bathroom renovation costs
Size of the space
A powder room renovation costs less than a primary ensuite. More square footage means more tile, more materials, and more labour.
Tile selection and quantity
Tile is one of the largest material cost variables. Large-format tiles, natural stone, and custom patterns cost significantly more than standard ceramic or porcelain — and typically require more skilled installation.
Plumbing changes
Moving plumbing is expensive. If your renovation keeps fixtures in the same locations, costs are lower. Relocating a toilet, tub, or shower drain adds significantly to both labour and materials.
Hidden conditions
In older homes, opening walls often reveals mold, rot, failing waterproofing, or out-of-code wiring. These need to be addressed before rebuilding and add cost that could not be foreseen in the original estimate. An experienced contractor identifies risk areas before quoting.
Waterproofing quality
Skimping on wet area waterproofing is the most common way bathroom renovations fail years later. Proper membrane installation adds modest cost upfront and prevents far more expensive water damage down the road.
Fixture and vanity choices
Builder-grade fixtures are available at much lower price points than designer or imported options. Both can look excellent — the difference is longevity, finish quality, and personal preference.
Why a quote matters more than an average
Online cost estimates are a starting point, not a plan. The only way to get an accurate number for your specific bathroom is to have an experienced contractor walk through it, assess the existing conditions, and scope the work honestly.
