Bathroom Renovation Cost: What Really Drives the Price

Any single number for “a bathroom” is close to useless, because two bathrooms of the same size can need completely different work. That is why we price every bathroom after a free visit. What we can tell you is exactly what moves the number, so you know what to expect before anyone comes out.

Want a ballpark for the tile part of the job right now? Our tile cost calculator gives you one in under a minute.

Scope and timeline

Scope What it involves Typical time
Floor tile only Remove old floor, level, membrane, tile 2–3 days
Tub surround retile New backer and waterproofing, wall tile 3–4 days
Full tiled shower Membrane, sloped base, niche, full-height tile 4–7 days
Full gut renovation Everything, plus vanity, toilet and fixtures 2–3 weeks

What moves the number

Subfloor condition. This is the single biggest unknown. In homes built between the 1970s and 1990s, we regularly pull up flooring to find a plywood subfloor that has been through thirty-plus Ontario winters. If it flexes, it has to be stiffened before tile goes down, because tile is rigid and cracks over a floor that moves.

Tile format. Large format tile costs more to install than standard, not because the tile is dearer but because the labour is. Every piece needs back-buttering, the subfloor has to be flat within 1/8 inch over 10 feet, and levelling clips go on every joint. Read more in our guide to large format tile installation.

Layout pattern. A straight lay is the baseline. Diagonal adds roughly 15 percent to labour and waste. Herringbone can add 30 percent or more.

Waterproofing. Non-negotiable, and if it is missing from a quote you are not comparing like with like. See our explainer on shower and wet room tiling.

Where the money actually goes

On a typical full bathroom, labour is the biggest share, then materials including tile, then fixtures, vanity, disposal and permits where required. Tile itself is rarely the biggest line item, which surprises most people.

Three ways to reduce cost without regretting it

  • Keep the plumbing where it is. Moving a toilet or shower drain means opening the floor, and it is one of the biggest single cost jumps in a bathroom.
  • Choose a mid-range porcelain. On a small bathroom floor the difference between a basic and a mid-range porcelain is small. Real marble costs more to buy and commits you to sealing it every one to three years.
  • Do not economise on waterproofing or membrane. These are the cheapest parts of the job and the most expensive to fix later.

What we would not cut

Waterproofing membrane, a properly sloped shower base, and an uncoupling membrane over plywood. Every failed shower we have been called in to repair skipped at least one of these.
