Small Bathroom Renovation Cost in Toronto (2026)

A full renovation of a small Toronto bathroom — the classic 5x8, three-piece, 40 sq ft layout — typically costs $15,000-$28,000 as of 2026. That covers demolition, new waterproofing, porcelain tile, a new tub or shower, vanity, toilet, lighting, and finishing, keeping fixtures where they are. Push into heated floors, custom glass, or a plumbing relocation and small bathrooms reach $30,000 and beyond.

Numbers below $15,000 exist, but they describe a different project: a cosmetic refresh — new vanity, toilet, paint, maybe a tub surround — with the original tile and waterproofing left in place. Nothing wrong with that scope; it just should not be compared against full-renovation quotes, which is where a lot of sticker shock starts.

Timeline for a small full reno is 2-3 weeks. Toronto pricing runs roughly 15-20% above the Ontario average, and small rooms do not escape that premium — for the wider market picture, see what a bathroom renovation costs in Toronto across all sizes.

Halving the square footage does not halve the price, and the reason is simple: a small bathroom needs every trade a large one does. The plumber still roughs in and connects a tub, toilet, and sink at GTA rates of $110-$200 per hour. The electrician still handles the fan, lighting, and any new circuit at $95-$150 per hour. The tile setter still waterproofs and tiles the wet area at $80-$125 per hour — and tight rooms with lots of cuts are slower per square foot, not faster.

Each of those trades carries mobilization costs and minimum charges that do not shrink with the room. Labour makes up roughly a third of a bathroom budget, and in a small bathroom the labour share climbs because the material savings are real but the hours barely move.

There is also sequencing. Demo, plumbing rough-in, electrical, waterproofing, tile, then fixtures and finishing — the order does not compress in a small room, and only one trade fits in a 5x8 at a time. That is why a 40 sq ft bathroom takes two to three weeks, not two to three days.

Here is how a mid-range $18,000-$25,000 small-bathroom renovation in Toronto typically breaks down in 2026:

• Demolition and disposal: tear-out to studs, bin, dust control.
• Plumbing rough-in and connections: $3,000-$5,000 — same-location tub, toilet, and vanity hookups.
• Electrical and lighting: $1,500-$3,000 — exhaust fan, vanity lighting, pot light, GFCI.
• Tile and surfaces: $3,000-$6,000 — standard porcelain runs $10-$25 per sq ft installed; large-format and stone cost more.
• Tub or shower, supplied and installed: $2,500-$5,000.
• Vanity and countertop: $1,500-$3,500.
• Waterproofing, paint, trim, accessories, and project management round out the balance.

Every line has a budget and premium version, which is how two honest quotes for the same room can sit $8,000 apart. Add-ons stack from there: heated floors at $1,500-$3,000, frameless glass at $2,000-$4,000, and moving any drain or valve at $2,000-$6,000. We price each line in writing so you can see exactly which choices are moving the total.

Small rooms genuinely save on anything bought by the square foot. Forty square feet of floor tile instead of ninety. One sheet of glass instead of two. A 24-inch vanity instead of a double. This is also where small bathrooms get their one luxury: a splurge tile that would blow the budget in a large ensuite might only add a few hundred dollars across a 5x8 — porcelain that mimics marble, a large-format tile that makes a small bathroom feel bigger, a heated floor covering barely 20 square feet.

What never shrinks: waterproofing, done right, costs what it costs — the shower gets a full membrane system regardless of room size. Trade minimums, permit fees where plumbing moves, and disposal are all flat. And in Toronto's older housing stock, small bathrooms often hide the same surprises as big ones: galvanized supply lines in pre-1960 homes, undersized venting, floors that need levelling. A 10-20% contingency applies to small projects just as firmly as large ones.

One clean saving worth naming: keep the layout. Fixture-for-fixture replacement needs no building permit in Toronto — but moving or adding drains triggers one, plus the plumbing work itself.

Much of Toronto's small-bathroom inventory sits upstairs in Victorian and Edwardian semis — Riverdale, Leslieville, Parkdale, Trinity-Bellwoods — where the bathroom was carved out of a bedroom a century ago and is long, narrow, and short on natural light.

The moves that reliably make these rooms feel bigger without moving walls: a wall-hung or open-leg vanity that shows floor underneath; clear glass instead of a shower curtain or framed slider; tile run floor-to-ceiling in one tone; a recessed niche instead of shelving that juts into the room; and a pocket door where the swing eats a third of the floor. Choosing the right tile for a small bathroom does more for perceived size than any other single decision — fewer grout lines, lighter tones, larger formats.

The bigger judgment call is the tub. In a one-bathroom semi, we usually advise keeping a tub for resale and family use. In a house with a second full bath, converting to a glass walk-in shower opens the room dramatically and costs less than most people expect within a full renovation.

A real small-bathroom quote comes from a site visit, not a text message with square footage. Age of the house, condition of the subfloor, what is behind the tile, whether the stack is cast iron — these swing a Toronto quote by thousands, and none of them are visible in photos.

When you compare quotes, compare scope: is waterproofing a named system or a vague line? Are tile, vanity, and fixture allowances specified in dollars? Is disposal included? A $14,000 quote that excludes waterproofing details and carries $2,000 in vague allowances is not cheaper than a $19,000 quote with everything in writing — it is just less finished.

Our take on when a small full renovation makes sense: if the bathroom is original, leaking, or mouldy, renovate fully — partial fixes on failed waterproofing are money burned. If the bones are sound and the look is the problem, a cosmetic refresh is legitimate and we will tell you so.
