A bathroom renovation in Toronto in 2026 can cost anywhere from $15,000 to $80,000 or more. That is a wide range, and it is not helpful on its own. This guide breaks down exactly what drives that number, what the typical cost is for each type of project, and what you should watch out for when comparing quotes.
What Actually Drives the Cost of a Bathroom Renovation
The single biggest factor is scope. A cosmetic refresh new tile over existing substrate, new vanity, new fixtures is a fundamentally different project from a full gut renovation where you demo everything to the studs, rebuild the waterproofing, and start from scratch. The labour, the materials, and the timeline are all different.
After scope, the factors that matter most are:
- Waterproofing quality Wedi Pro certified waterproofing costs more than basic membrane, but it comes with a 10-year warranty and dramatically lower failure rates. This is the one place where cutting corners costs more in the long run.
- Tile selection Large-format porcelain slab costs more than standard tile in both material and labour. The installation is more demanding and requires a properly prepared substrate.
- Plumbing changes Moving a drain, relocating a toilet, or adding a second showerhead adds plumbing labour and usually a permit.
- Structural work Removing or relocating a wall changes the entire scope and cost of the project.
- Fixture quality Vanities, faucets, shower systems, and mirrors vary enormously in price. We help clients balance quality and budget during material selection.
Pricing Breakdown by Project Type
These are realistic ranges based on current market conditions in Toronto and the GTA. They assume professional installation with proper waterproofing.
New tile over prepared substrate, new vanity, fixtures, and accessories. No structural changes, no plumbing moves.
Complete demolition to studs, Wedi Pro waterproofing, new tile, new vanity, all new plumbing fixtures. This is the right approach for bathrooms with existing moisture damage or tile over plaster.
Full gut, walk-in shower, double vanity, heated floors, standard fixtures. Wedi Pro waterproofing throughout.
Full gut, large-format slab tile, custom shower with niche and bench, freestanding tub, double vanity, heated floors, premium fixtures and hardware.
Hidden Costs to Watch For
The gap between a low quote and a final bill is almost always one of these:
- Waterproofing not included Some contractors quote tile installation but leave waterproofing as a separate line item or exclude it entirely. Ask specifically what waterproofing system is included and what warranty it carries.
- Substrate preparation not scoped If the existing floor or walls are not properly prepared, the tile will fail. A proper quote includes the cost of levelling and substrate work, not just the tile itself.
- Permits If your renovation involves plumbing relocation or electrical work, a permit is required. This adds cost and timeline but is not optional. Contractors who tell you permits are unnecessary for plumbing moves are cutting corners.
- Discovery costs What is behind the wall in a Toronto home built before 1980 is often a surprise. Old waterproofing failures, galvanized pipes, knob and tube wiring. A trustworthy contractor documents any discovery and gets your approval before doing additional work.
How to Budget Properly
Set your realistic budget first, then work backward to scope. A common mistake is to set a budget based on what you hope it will cost rather than what it realistically does cost. A $20,000 budget is genuinely great for a small bathroom cosmetic refresh. It is not realistic for a full gut master bathroom renovation.
A 10 to 15 percent contingency on top of the quoted price is standard in renovation budgeting. Not because contractors are unreliable, but because Toronto homes particularly pre-war and post-war builds regularly produce surprises behind the walls.
If your budget is tight, the best approach is to do fewer rooms but do them properly. A single bathroom done right with Wedi Pro waterproofing will outlast three bathrooms done cheaply.
Getting an Accurate Quote
A good renovation quote is line-by-line. It lists demolition, waterproofing system, substrate preparation, tile material and installation, plumbing work, electrical work, fixtures, and any structural changes as separate line items. If a quote is a single number with no breakdown, you have no way of knowing what is included and what is not.
