What Affects the Cost?
Plumbing Relocation
Moving drains, supply lines, or adding fixtures adds $2,000–$6,000. Keeping fixtures in place significantly reduces cost.
Tile Selection
Basic ceramic tile is the budget option; large-format porcelain or natural stone can cost several times more with labour. Budget $2,500–$8,000 for a typical bathroom.
Fixture Quality
A basic toilet costs a few hundred dollars. High-end models with bidet seats and soft-close features cost many times more.
Waterproofing
Proper waterproofing (Kerdi, Wedi) adds $1,000–$2,500 but is essential to prevent moisture damage behind walls and under floors.
Licensing in Ontario
Bathroom renovations require licensed plumbers (Skilled Trades Ontario) for any plumbing changes and ESA-licensed electricians for electrical work. GFCI outlets are required by Ontario code in all wet areas.
Frequently Asked Questions

A simple update takes 1–2 weeks. A full gut renovation typically takes 3–6 weeks, depending on complexity and material availability.
