Small Bathroom Renovation Cost in Ontario (2027 Prices)
Planning a small bathroom renovation in Ontario for 2027? Expect the bill to surprise you. Tiny rooms don’t come with tiny price tags, because demolition, waterproofing, plumbing and permits cost roughly the same whether the room is 35 or 70 square feet.
No Ontario contractor has published 2027 rate cards yet. The figures below come from current 2026 pricing for Mississauga, Toronto, Vaughan, Milton and the wider Greater Golden Horseshoe, which is the most reliable starting point for a project booked next year.
What is a small bathroom renovation?
A small bathroom renovation updates a bathroom of about 40 square feet or less, such as a 5×8 main bath, a 4×7 condo bath or a two-piece powder room. Scope runs from a cosmetic refresh with a new vanity, toilet and lighting to a full gut that replaces the shower or tub, waterproofing, tile and fixtures.
The 5×8 layout is the Ontario standard. A typical Toronto condo bathroom measures 5 by 8 feet, or 40 square feet, and many post-war houses use the same footprint.
Size matters less than you’d think. Small bathrooms nearly always cost more per square foot than large primary ensuites, since permits, demolition and waterproofing are close to fixed costs regardless of room size. Labour drives most of the spend: in a typical mid-range Ontario bathroom, labour and trade services account for 55 to 65 percent of the total, with fixtures and materials making up the rest.
How much does a small bathroom renovation cost in Ontario?
Most small bathrooms in Ontario cost $12,000 to $25,000 before tax. A cosmetic refresh starts near $12,000, a full gut of a 4×6 or 4×7 bath runs about $15,000 to $22,000, and condo units cost 10 to 15 percent more. Relocating plumbing or choosing premium finishes moves a project into the $30,000-plus range.
| Project scope | Typical Ontario cost (2026 baseline for 2027) | What it usually covers |
|---|---|---|
| Powder room, full gut | $8,000 to $14,000 | Floor tile, vanity, toilet, lighting, drywall |
| Cosmetic refresh, same layout | From about $12,000 | New vanity, fixtures, lighting, tile, paint |
| Full gut, 4×6 or 4×7 bath | $15,000 to $22,000 | Demolition, waterproofing, tub or shower, tile |
| Condo bathroom | Add 10% to 15% | Board approvals, elevator deposits, limited work hours |
| Layout change or premium finish | $30,000 to $60,000 | Moved plumbing, heated floor, custom vanity |
Sources for these ranges include Toronto pricing that puts a small 4×6 or 4×7 full gut at $15,000 to $22,000, powder rooms at $8,000 to $14,000, and condo bathrooms about 10 to 15 percent higher, along with Leedway Group’s 2026 Mississauga range of $12,000 to $50,000+, depending on scope.

Bathroom remodel cost by trade
Tile and plumbing eat the budget. In 2026, Toronto plumbers charge $95 to $140 an hour and tile setters $12 to $20 per square foot installed, so basic tile work alone in a small bathroom reaches $3,000 to $5,000. Heated floors add more: an electric system for a typical small bathroom costs $1,500 to $3,000 installed.
Shower renovation and bathtub replacement
A tub-to-shower conversion is the most common shower renovation in compact homes. Toronto contractors quote $2,500 to $6,000 at the lower end and $4,000 to $8,000 including demolition, plumbing changes, waterproofing, tile, glass and fixtures at the higher end. A straight bathtub replacement is similar: Toronto bathtub installation averages $2,500 to $5,000.
Think before removing your home’s only tub. Losing the bathtub can turn off some future buyers, especially families with young children.
HST, permits and the real bathroom renovation price
Every quote should add Ontario’s 13% HST, as set out by the Canada Revenue Agency. That turns a $25,000 project into $28,250.
Permits depend on what moves. Most projects that relocate a sink, tub or shower need a City of Mississauga building permit, while like-for-like replacements usually don’t. Fees are modest next to the build: Milton charges a flat $264.20 for new plumbing, and Vaughan permits for plumbing or structural changes typically run $200 to $500.

How does compact bathroom design keep a bathroom remodel on budget?
Compact bathroom design saves money by keeping the toilet, sink and shower drain where they already sit, since relocating plumbing is the single largest cost driver. Smart fixture choices, such as a floating vanity and a frameless glass panel, make a 40-square-foot room feel bigger without moving a single pipe.
Keeping the existing layout is the cheapest way to renovate a bathroom, according to Leedway’s Mississauga guide. From there, a few design moves stretch the space: leedwaygroup
- Swap a bulky cabinet for a wall-mounted bathroom vanity to expose more floor
- Pair it with a wall-hung toilet for a cleaner sightline
- Replace a framed tub door with a fixed glass panel, since sliding tracks visually cut the room in two
- Choose porcelain floor tile, which resists water and scratches better than ceramic at a similar price leedwaygroup
The Vaughan guide notes that sliding glass tub doors break up a small room visually, and pairs a wall-hung toilet with a floating vanity for tight spaces.
Get three quotes. Honest bids for the same scope usually differ by 10 to 15 percent, and a $7,000 quote for a full bathroom renovation is unrealistically low in 2026. Cash deals with unregistered contractors carry real risk; the CRA’s guidance on the underground economy and hiring contractors explains what to check.
Federal tax credits worth checking
Accessibility work can earn money back. The Home Accessibility Tax Credit on line 31285 applies when the person benefiting is 65 or older at year end or eligible for the disability tax credit, with up to $20,000 per year in eligible expenses. At the 14% lowest federal rate used for 2026, a full $20,000 claim could cut federal tax by up to $2,800. Upgrades done mostly to raise home value don’t qualify.

Frequently Asked Questions
1. How much does a small bathroom renovation cost in Ontario in 2027?
Based on current 2026 Ontario pricing, a small bathroom costs about $12,000 to $25,000 before 13% HST. Powder rooms run $8,000 to $14,000, condo bathrooms add 10 to 15 percent, and projects that move plumbing or use premium tile can climb to $30,000 or more.
2. Do I need a building permit to renovate a small bathroom in Ontario?
Permits are usually required when a sink, tub or shower moves or new plumbing is added. Like-for-like replacements of a vanity, toilet or tile normally need no permit. Municipal fees are modest; Milton charges a flat $264.20 for new plumbing, while Vaughan typically charges $200 to $500.
3. Is a tub-to-shower conversion cheaper than a full bathroom remodel?
Yes. A tub-to-shower conversion in the Toronto area costs roughly $2,500 to $8,000, compared with $15,000 to $22,000 for a full gut of a small bathroom. The conversion keeps the drain location, so most of the savings come from avoiding new plumbing runs and full-room demolition.
4. How long does a small bathroom renovation take in Ontario?
A cosmetic small bathroom update in Mississauga usually takes one to two weeks once materials are on site. Full guts and permit-based work take longer, and custom vanities or shower glass can add lead time, so order long-lead items before demolition starts.
5. What are the best ways to lower a bathroom renovation price?
Small changes add up quickly:
- Keep the toilet, sink and shower drain in their current spots
- Choose a stock bathroom vanity over custom cabinetry
- Use porcelain tile instead of natural stone
- Collect three written quotes and compare scope line by line
- Check whether accessibility work qualifies for federal tax credits
