Bathroom Renovation Cost in Toronto (2026 Guide)
Bathrooms are deceptively expensive. A 5x8 space can easily cost $25,000 to renovate in Toronto in 2026 — that's almost $625 per square foot. Why so much? Because behind every bathroom wall is plumbing, electrical, waterproofing, ventilation, and a lot of skilled labor. Here's what you actually need to know before you start.
2026 Toronto bathroom renovation costs
Honest pricing for bathroom renos this year, broken into the four most common types:
| Bathroom Type | Budget | Mid-Range | High-End |
|---|---|---|---|
| Powder room (2-piece) | $8K – $14K | $15K – $25K | $28K – $45K |
| Standard 3-piece | $15K – $25K | $28K – $45K | $50K – $80K |
| Standard 4-piece | $20K – $32K | $35K – $58K | $65K – $110K |
| Master ensuite (5-piece) | $30K – $48K | $55K – $85K | $95K – $200K+ |
Quick definitions if you're not sure what these mean:
- Powder room (2-piece): toilet + sink only
- 3-piece: toilet + sink + shower OR tub
- 4-piece: toilet + sink + shower + tub (or shower-tub combo)
- Master ensuite (5-piece): double sink + toilet + standalone shower + standalone tub
Why bathrooms cost so much per square foot
People always ask "why does a small bathroom cost almost as much as a small kitchen?" Here's why:
- Plumbing density: A kitchen has 1-2 water connections. A bathroom has 4-6. More plumbing = more labor + materials.
- Waterproofing requirements: Shower walls need proper waterproofing (Schluter, Kerdi, or equivalent). Mess this up and you get mold/rot in 2 years.
- Tile labor: Bathroom = lots of tile = lots of skilled labor. Tile setters charge $8-15/sqft just for installation.
- Ventilation: Required by code, must vent outside (not into attic), often involves running new ducting.
- Electrical complexity: GFCI outlets, dedicated circuits, exhaust fan wiring, lighting, sometimes heated floors.
- Demolition is messy: Old tile, old shower pans, sometimes lead pipes — disposal alone can be $500-1500.

The 7 most expensive mistakes Toronto homeowners make
1. Skimping on waterproofing
This is THE most common mistake. Bad waterproofing = water gets behind tiles = mold and rot within 2-3 years. We've torn out 5-year-old bathrooms because the waterproofing was done wrong (or skipped entirely). Always use proper systems (Schluter Kerdi or equivalent) under tiled showers. Never accept "we'll just use cement board" as the entire waterproofing strategy. Cement board is the substrate, not the waterproofing.
2. Cheap exhaust fan or no exhaust fan
Toronto winters mean lots of hot showers. Without proper ventilation, all that humidity goes into your walls and ceiling — leading to mold, peeling paint, and a soggy bathroom forever. Get a proper Panasonic fan (90+ CFM, vented outside), not the $50 builder-grade Home Depot special.
3. Not running plumbing for future fixtures
Doing a bathroom and don't have budget for the freestanding tub or rainfall shower? Run the plumbing for them anyway. Capped off behind drywall costs $200 now vs $3,000+ to retrofit later.
4. Choosing trendy tile that ages badly
Subway tile from 2015 still looks great. Hexagon mosaic backsplash from 2018 already looks dated. Go timeless: white/neutral tile, simple patterns, classic finishes. Add personality through paint and accessories you can swap.
5. Putting a small bathtub when you have space for big
Bathtubs sell homes. If you're doing a master ensuite, get the freestanding tub. Even if you'll mostly shower, the tub adds resale value disproportionate to cost.
6. Forgetting storage
Plan vanity drawers, medicine cabinets, niches in the shower for shampoo. Adding storage after tile is installed is expensive and often impossible.
7. Cutting corners on plumbing rough-ins
Cheap PEX, plastic shutoffs, no shutoff valves at fixtures — these are nightmare scenarios when something leaks. Pay for quality copper or premium PEX, brass shutoffs, easy access valves.
Timeline: How long a Toronto bathroom reno takes
- Powder room: 1-2 weeks
- Standard 3-piece: 2-3 weeks
- Standard 4-piece: 3-4 weeks
- Master ensuite (luxury): 4-6 weeks
Realistic breakdown for a standard 4-piece:
- Week 1: Demo + plumbing rough-in
- Week 2: Electrical + framing + drywall + waterproofing
- Week 3: Tile + grout + paint
- Week 4: Vanity + toilet + plumbing finish + final electrical + walk-through
If you only have ONE bathroom in the house — plan accordingly. We've had clients shower at the gym for 3 weeks. Some go stay with family. Some get a portable toilet rental. Plan ahead.
Do I need a permit for a Toronto bathroom reno?
The short answer: usually yes. Specifically:
- Moving plumbing locations → permit required
- Adding new electrical circuits → permit required (ESA)
- Modifying structural elements → permit required
- Adding a brand new bathroom where none existed → permit required
- Like-for-like swap (same toilet location, same shower location, just refresh) → technically no permit needed but check with your contractor
⚠️ Skip permits at your peril. If you sell your house and the inspector finds unpermitted plumbing or electrical, the buyer can demand you rip it out and redo it with permits. We've seen sales fall apart over this. The $500-1500 permit cost is cheap insurance.
What you can save money on (and what you can't)
Smart places to save:
- Vanity: IKEA Godmorgon is genuinely great and 1/3 the price of custom
- Toilet: $400 toilets work as well as $1,500 ones for most families
- Mirror: Frameless mirror from Home Depot ($150) looks identical to designer ($800)
- Standard tile: Cheap subway tile installed well looks better than expensive tile installed badly
- Standard chrome fixtures: Last forever, never look dated
Don't cheap out on:
- Waterproofing (already covered — non-negotiable)
- Exhaust fan (already covered)
- Shower valve/cartridge (cheap ones fail in 5 years, expensive in your wall)
- Floor tile installation labor (bad floors crack; redo costs $4-8K)
- Plumbing labor (one leak destroys ceilings, costs $5-15K to fix)

Bathroom renos return roughly 60-70% of cost in resale value in Toronto. Less than kitchens (which return 70-90%), but still positive.
The real return isn't pure ROI — it's:
- You enjoy the bathroom for X years
- House sells faster with updated bathrooms
- Buyers don't lowball as hard if bathrooms are done
- Master ensuites in particular are make-or-break for higher-end Toronto buyers
The renovations that don't pay back: ultra-luxury master ensuites in mid-range homes (overbuilding for your neighborhood). A $80K spa bathroom in a $1.2M home is overbuilt. The same in a $3M home is appropriate.
How to choose a Toronto bathroom contractor
Bathroom renos are specialty work. Beyond general contractor qualifications (see our hiring guide), ask specifically:
- "How many bathrooms have you done in the last year?" (Want 10+)
- "What waterproofing system do you use?" (Schluter Kerdi is gold standard)
- "Are you using a licensed plumber for the rough-in?" (Must be yes)
- "How do you handle the exhaust fan venting?" (Must vent outside, not into attic)
- "Can you show me 2-3 bathrooms you've done in the last year?" (Recent work matters)
The bottom line
Toronto bathroom renos in 2026 are not cheap, but they're one of the best investments you can make in your home — both for your daily quality of life and for resale.
The mistakes that cost the most are invisible: bad waterproofing, weak ventilation, poor plumbing. The mistakes that cost the least are visible: trendy tile, gold fixtures, fancy mirrors. Spend on what's hidden, save on what's swappable.
