Bathroom Renovation Cost in the GTA (Quotes, Room by Room)

Across six GTA renovation firms that publish 2026 price lists, three of them put a powder room at $3,000 to $12,000, while Senso Design's high-end tier for the same room reaches $24,000, for a standard three-piece bathroom $12,000 to $30,000, and for a standard primary ensuite $25,000 to $45,000, with luxury ensuites quoted past $70,000. Those are contractors' asking prices, before HST. No government sets them. What moves a quote most is not room size but whether the drains move, and if they do you need a City permit. Toronto's minimum fee is $214.79 for all work, but where the plumbing is part of a larger permitted job, the City's related plumbing & drain permit guide charges no additional fee for it.

What GTA firms publish, room by room

Every number below is published by a named company on its own site; compare what each range includes, not the headline.

Powder rooms are cheapest because there is no shower: no waterproofing system, no tiled wet wall, no glass. FP Tile & Marble publishes $3,000 to $12,000, Riteway $4,000 to $12,000, Magic Reno $5,500 to $12,000 over five to eight working days. Senso Design splits the room three ways: $5,000 to $8,000 basic, $8,000 to $15,000 standard, $15,000 to $24,000 high-end. The spread shows how much finishes decide the price.

A standard three-piece is where most GTA homeowners land. Riteway publishes $12,000 to $25,000; Magic Reno $12,900 to $20,000 with an alcove tub and $14,500 to $25,000 with a tiled walk-in shower; Senso and FP Tile & Marble both $12,000 to $30,000, Senso averaging near $17,000. Riteway says its own three-piece jobs start at $20,000 to $22,000. A published range and an actual starting price are not the same thing.

Primary ensuites spread widest, because scope stops being standard. FP Tile & Marble publishes $25,000 to $40,000, Riteway $26,000 to $45,000 standard and $45,000 to $70,000+ luxury, Leedway Group $40,000 to $70,000 or more. Country Reno prices by scope instead of room, putting a high-end transformation at $44,000 to $82,500+; FP goes higher still, listing high-end and luxury bathrooms at $70,000 to $100,000+.

Condo bathrooms cost more than the same work in a house. Senso Design and FP Tile & Marble both put the premium at 10 to 20 per cent, which Senso attributes to logistics, not construction: restricted weekday hours, elevator bookings at $200 to $500 a day, a $500 to $2,000 damage deposit, $2 million liability insurance, two to six weeks of board approval.

Where the money actually goes

Three of the six firms publish a labour share and none agrees: Magic Reno says labour is typically 60% of a Toronto bathroom budget against 40% materials, FP Tile & Marble 40 to 60 per cent, Leedway Group 50 to 60 per cent. Riteway points elsewhere, calling the shower area the single largest cost at 30% to 40%. Each row below is one firm's own line item, both ends from that same item.

Two notes. Senso Design's vanity high is written $4,000+: a floor for custom millwork, not a ceiling. And waterproofing at $500 to $1,800 is the cheapest insurance in the job and the easiest for a low bid to omit; Magic Reno's process ends in a documented 24-hour flood test before tile, which is the thing to ask for by name.

What drives a quote up most

Moving the drain

This is the one. Riteway Construction publishes $2,000 to $6,000 in extra plumbing alone for moving a toilet to the opposite wall, shifting the shower or adding a second sink, "plus a permit and inspections." Magic Reno lists drain relocation at $500 to $3,000 on top of its rough-in, Leedway Group $2,000 to $3,500, with licensed GTA plumbers at $90 to $150 an hour. Keeping the layout is worth $2,000 to $5,000 by Senso's estimate.

Tile

Riteway says tile alone can swing a budget by $5,000 or more. Standard porcelain runs $10 to $25 per square foot installed by Riteway's numbers, $8 to $25 by Magic Reno's. But Magic's is installation labour only, with tile bought separately at $1.50 to $15 a square foot on the same page, so the two are not the same number; large-format slabs run $25 to $50 at Magic Reno, $40+ at Riteway. FP Tile & Marble prices marble at $20 to $40 and natural stone at $15 to $30 installed. A custom niche or bench adds about $1,000 at both Senso and Magic Reno.

What is behind the walls

Older GTA housing stock is where fixed-price quotes go to die. Senso Design publishes knob-and-tube wiring at $800 to $3,000 in the wet zone, lead or galvanized piping at $1,200 to $4,000, mould at $800 to $5,000, a rotten subfloor at $500 to $2,500. Riteway lists asbestos abatement in pre-1980 homes at $2,000 to $5,000 and mould remediation at $1,000 to $3,000+. Both recommend a 10 to 15 per cent contingency and a written change order (photo, description, price) before work continues.

When a bathroom renovation needs a City permit

Toronto's own list is unusually clear. Under the Building Code Act a permit is required to "install or modify heating and or plumbing systems" and to make structural or material alterations such as adding or removing walls. The City's Homeowner's Guide to Building Permits puts interior renovations with a "new or altered plumbing or mechanical system" on that list too.

On the other side of the line, the City lists "repairing and replacing plumbing fixtures" among work that does not require a permit, so a like-for-like swap, retiling and paint is generally permit-free. Move the drain, add a fixture, take out a wall or add a bathroom, and you are in permit territory. The City caveats that exempt list: it "is not exhaustive and judgment should be used depending on the situation and circumstances associated with the project." The Zoning Bylaw applies either way.

Fees come from the municipality, not a contractor's summary sheet.

Run that on a real bathroom and the two cities diverge. A 5-by-8-foot bathroom is 40 square feet, or 3.72 m². In Toronto the alteration charge is 3.72 × $11.53 = $42.89, far below the floor, so you pay the $214.79 minimum. Mississauga's alterations line charges its rate "(plus the minimum applicable fee)", reading as $244.00 + 3.72 × $6.84 = $269.44. Schedule B's preamble also uses floor language ("no less than $244.00"), but a pure floor would leave that parenthetical doing nothing. Toronto's minimum is a floor small work never clears; Mississauga's reads as a base.

Toronto runs two plumbing streams, and which one you are in decides whether the plumbing adds anything. A related plumbing and drain permit covers "work which is related to other construction proposed for a building": a bathroom where the sink moves and a wall comes out. Its Required Fees section opens: "No additional fee if submitted with building application." Filing it after the building permit application is the City's own instruction, not a penalty: "you must apply for a related plumbing & drain permit online after your original building permit submission."

The test is relatedness, not timing. The stand-alone permit is the other stream ("for work which is not related to other construction proposed for a building"), and that guide is where the per-fixture rates live: $23.20 per fixture in a single-family dwelling, $30.94 in all other buildings, which is where a condo apartment lands. Three fixtures is 3 × $23.20 = $69.60, under the floor, so a stand-alone three-fixture permit costs the $214.79 minimum. Mississauga's $42.23 is labelled "(Plumbing review only)".

The exemption stops at the wall: the related guide still charges for Site Servicing outside the building (water service, sanitary and storm sewer piping, manholes, catch basins) at $214.79 flat for buried piping at a house and $38.67 each for backwater valves and manholes.

Two official costs sit outside the building permit. Electrical work is notified to the Electrical Safety Authority, not the City; the ESA publishes a minimum residential notification fee of $88 and says it varies with the work. And the CRA's rate table lists Ontario's HST at 13%.

Timing: Toronto reviews complete House Stream applications within 10 business days, and its Express Services stream, which covers interior alterations and stand-alone plumbing and drain permits, targets 3 business days after intake. An application without a Zoning Applicable Law Certificate counts as incomplete, and those have no review time frame.

How to read a quote

Get three and compare line by line, not at the bottom. Senso Design's framing is right: three quotes spanning $12,000 to $24,000 usually differ in scope, not greed.

• Is HST in or out? Almost every GTA quote is pre-tax. Senso Design's sample three-piece shows it: $18,500 subtotal, $2,405 HST, $20,905 total.
• Is waterproofing named as a system, with a flood test? Not just "we waterproof."
• Who pulls the permit? Ask which ones (building, plumbing, HVAC), whether the fee is in the price, and who books inspections.
• Is debris removal included? A real line: $300 to $800 at Riteway, $500 to $750 at Magic Reno.
• What is the written change-order process, and the payment schedule?
• Is there a contingency? Budget 10 to 15 per cent yourself even if the quote does not.

Riteway Construction puts it well: "A $3,000 lower quote that excludes waterproofing, doesn't include disposal, and skips the building permit isn't actually cheaper. It's the same renovation with the risk shifted to you."
