A condo bathroom renovation in Toronto costs $15,000 to $35,000 in 2026 for a full renovation, and takes 2 to 4 weeks of construction once your condo board approves the work. Approval itself takes 2 to 6 weeks, which surprises more owners than the price does. A cosmetic refresh runs $8,000 to $15,000, a powder room $6,000 to $12,000, and a large ensuite with premium finishes can reach $40,000.
Renovating a bathroom in a condo is not a smaller version of renovating one in a house. It is a different job with its own rules, its own paperwork and its own risks, most of which sit behind the wall you share with a neighbour. This guide covers all of it: what it costs, what your board will and will not allow, the approval process step by step, and the two problems hiding inside Toronto condo walls that nobody budgets for.
Condo Bathroom Renovation Costs at a Glance
| Project | Typical cost (2026) | Construction time |
| Cosmetic refresh (vanity, toilet, paint, lighting) | $8,000 to $15,000 | 1 to 2 weeks |
| Full 3-piece renovation (strip to studs) | $15,000 to $25,000 | 2 to 3 weeks |
| Full 4-piece or ensuite renovation | $25,000 to $40,000 | 3 to 4 weeks |
| Powder room | $6,000 to $12,000 | 1 week |
| Tub-to-shower conversion (within a full reno) | adds $2,500 to $6,000 | included |
Prices exclude HST (13 percent in Ontario) and assume the fixtures stay roughly where they are, which in a condo they usually must. Add 2 to 6 weeks of board approval time before construction can start.
Why a Condo Bathroom Is a Different Job Than a House Bathroom
In a house, your bathroom is yours from the studs out. In a condo, you own the space between the walls, and everything serving it is shared. The drain runs into a vertical plumbing stack serving every unit above and below you. The floor is a concrete slab you cannot casually cut into. The ventilation ties into building systems, and the wall behind your shower may be a fire-rated assembly. That is why your condo board gets a say, and why the contractor who did a beautiful job on your friend’s house can still make a mess of your condo.
Labour also carries more of the budget in a condo, often 50 to 60 percent. Everything arrives through a booked elevator, the crew works inside strict hours, and the waterproofing has to be done to a standard where a mistake does not become your neighbour’s ceiling. For how condo costs compare to a house bathroom, our bathroom renovation cost breakdown puts the two side by side.
What You Can and Cannot Change
| Change | Usually allowed? |
| Vanity, toilet, tub, tile, lighting, paint, mirrors | Yes, with board notification or approval |
| Tub-to-shower conversion in the same footprint | Yes in most buildings, with approval |
| Heated floors, new pot lights, upgraded fan | Usually, with licensed trades and approval |
| Moving the sink or toilet a short distance | Sometimes, if the slab and stack allow it |
| Relocating the bathroom or moving the drain stack | Almost never |
| Anything touching load-bearing walls or the slab | Only with engineering and corporation consent |
The honest rule: plan around the plumbing you have. Keeping the toilet, sink and drain where they are is what keeps a condo bathroom at $15,000 to $25,000 instead of drifting past $40,000, and it is also what gets your application approved the first time.
The Board Approval Process, Step by Step
This is the part most guides skip and most owners underestimate. Expect these steps in a typical Toronto building:
- Read your building’s renovation rules. Every corporation has them: permitted hours, elevator rules, what needs approval. Get them from property management before you plan anything.
- Submit a renovation application. Scope of work, drawings if the layout changes, your contractor’s licence information and a certificate of insurance naming the condo corporation, usually for $5 million in liability.
- Sign the alteration agreement. For changes to your unit, many corporations require a Section 98 agreement under Ontario’s Condominium Act. It registers the alteration and sets out who maintains and insures it. It sounds scary, it is routine, and your contractor should have seen dozens of them.
- Pay the deposit. Many buildings hold $500 to $2,000 against damage to common areas. You get it back after a walkthrough.
- Book the elevator and follow the hours. Most buildings allow renovation work on weekdays between roughly 9 a.m. and 5 p.m., with no noisy work on weekends. Your schedule has to be built around that, not squeezed into it.
Approval takes two to six weeks depending on the building, and nothing about your renovation can legally start before it lands. A contractor who prepares the whole package for you, the way we do on every Toronto condo renovation, turns this from a two-month headache into paperwork you barely notice.
The Two Problems Hiding in Toronto Condo Walls
Kitec plumbing (buildings from about 1995 to 2007)
Thousands of Toronto condos built or plumbed between the mid 1990s and 2007 carry Kitec, an orange-and-blue pipe system that was recalled because its fittings can corrode and fail. Insurers ask about it, buyers’ lawyers ask about it, and some boards now require its removal during any renovation that opens the walls. If your building is from that era, a bathroom renovation is the cheapest moment you will ever have to replace it, because the demolition is already paid for. Ask your contractor to check before quoting, not after.
Original shut-off valves and rough plumbing
In buildings from the 1970s and 80s, the shut-off valves and rough plumbing behind the fixtures are often original, seized or weeping. Replacing them mid-renovation is trivial. Discovering them after the new tile is up is not. This is exactly the kind of item that separates a real itemized quote from a low bid, and our guide to comparing contractor quotes shows how to spot the difference.
Waterproofing: the Part Your Neighbour Cares About
In a house, a waterproofing mistake ruins your subfloor. In a condo, it ruins the ceiling of the unit below, and depending on your corporation’s rules, the insurance deductible for that damage can land on you. This is why serious condo contractors use a full membrane system behind the shower, flood-test it, and photograph the work before tile goes on. When you interview contractors, ask one question: what is your waterproofing system, and can I see photos from your last condo job? A confident answer to that question is worth more than any showroom.
Design: Making 40 Square Feet Feel Twice Its Size
Most Toronto condo bathrooms run 35 to 55 square feet. The size is fixed. How big it feels is not:
- Go wall-hung. A floating vanity and wall-hung toilet expose floor, and visible floor is what the eye reads as space.
- Trade the tub for frameless glass. A clear walk-in shower removes the single biggest visual barrier in the room.
- Use large-format tile, floor to ceiling. Fewer grout lines in a light tone make walls recede. Continuing the floor tile into the shower stretches the room further.
- Build storage into the walls. Recessed niches, a recessed medicine cabinet and a mirrored wall add function without stealing a centimetre.
- Layer the lighting. A backlit mirror, pot lights and a light in the shower end the single-sad-fixture look most builder bathrooms ship with.
We go deeper on all of this in our guides to renovating a small condo to maximize space and bathroom renovation ideas that make your home stylish, and if you are torn on the vanity, here is our honest take on prefabricated versus custom bathroom vanities.
Should You Keep the Tub?
If your condo has two bathrooms, convert one to a walk-in shower without a second thought. If it has one, think about your buyer before you decide. Families and some investors still want at least one tub in the unit, so removing your only one can narrow the market when you sell. Plenty of downtown one-bed owners do it anyway and never regret the daily upgrade. It is a lifestyle call, not a rule, but make it knowingly.
The Real Timeline, Start to Finish
| Stage | Time |
| Design, quotes and contractor selection | 2 to 4 weeks |
| Board application and approval | 2 to 6 weeks |
| Materials ordered and delivered | 2 to 4 weeks (overlaps approval) |
| Construction | 2 to 4 weeks |
| Board walkthrough, deposit returned | 1 week |
Call it two to three months door to door, of which only a few weeks are actual construction. The trick is running the approval and the material orders at the same time, so the day the board says yes, the crew and the tile are both ready. We map the whole sequence in our condo renovation timeline guide.
Is It Worth Renovating a Condo Bathroom?
In a market where thousands of nearly identical units compete, the bathroom is one of the few rooms that can make yours the one buyers remember. A dated 1980s bathroom actively discounts a listing; a fresh, well-lit one photographs like a boutique hotel and helps a unit sell faster. If you are renovating to rent, a durable modern bathroom also justifies stronger rent and attracts tenants who stay. We break down which upgrades actually move value in our guide to condo renovations that increase value, and the cost to renovate a condo in Toronto if you are weighing the whole unit.
Frequently Asked Questions
Do I need condo board approval to renovate my bathroom in Toronto?
For anything beyond paint and accessories, yes. Expect to submit your scope of work, your contractor’s insurance certificate and sometimes drawings, and to sign an alteration agreement. Approval typically takes 2 to 6 weeks.
How much does a condo bathroom renovation cost in Toronto?
Most full condo bathroom renovations cost $15,000 to $35,000 in 2026. A cosmetic refresh runs $8,000 to $15,000, a powder room $6,000 to $12,000, and a large ensuite with premium finishes can reach $40,000. HST is extra.
Can I move the toilet or sink in my condo bathroom?
Short moves are sometimes possible if the concrete slab and the plumbing stack cooperate, but relocating fixtures is the fastest way to double a condo bathroom budget. Most renovations keep the fixtures where they are and spend the money on finishes instead.
How long does a condo bathroom renovation take?
Two to four weeks of construction, plus 2 to 6 weeks of board approval and material lead time before it. Plan on two to three months from first quote to finished room.
Can I replace the bathtub with a walk-in shower in my condo?
In most buildings, yes, with board approval, since the footprint and drain stay put. If it is the only tub in the unit, weigh the resale question first: some buyers still want one.
What is Kitec plumbing and does my condo have it?
Kitec is a recalled pipe system used widely in Toronto condos built from about 1995 to 2007. Its fittings can fail, insurers flag it, and a bathroom renovation is the cheapest time to replace it because the walls are already open. A contractor can confirm it with one look behind an access panel.
What hours can renovation work happen in a Toronto condo?
Most corporations allow work on weekdays roughly 9 a.m. to 5 p.m., with no noisy work on evenings, weekends or holidays. Your building’s rules govern, and your contractor’s schedule has to respect them from day one.
