Bathroom renovation · Mississauga, Ontario
Calico Designs and Renovations renovates bathrooms in Mississauga homes, townhouses, and condos, from a like-for-like update to a full rebuild with a new layout. As a starting guide, bathrooms run from about $12,000 to $70,000 or more depending on the tier. You can approve a 3D rendering first, and we handle City of Mississauga permits when fixtures are added, removed, or moved.
Free first consultation and site visit in Mississauga.
Ask for a full rendering of your project and approve the design before anything is built.
We don’t demolish at contract signing. Your old kitchen stays in place through design and sign-off, then demolition and installation happen back to back. You are without a working kitchen for only 2 days.
We work within your budget, as long as it is realistic, and design from your mood board and inspiration photos.
What a bathroom renovation involves in Mississauga depends mostly on the decade the house was built and on whether it is a detached house, a townhouse, or a condo.
Many houses from the 1950s and 1960s were built with a single main bathroom and, at most, a basic toilet and sink in the basement. Two requests come up again and again:
The second needs a City permit; the first usually does not, provided fixtures stay where they are.
These houses typically have a main bathroom, a small ensuite with a shower stall or a narrow tub, and a powder room. Ensuites from this period are tight. The common fix is to borrow space from the bedroom closet for a larger shower and a longer vanity, which means moving a wall and a drain, and therefore a permit.
Original bathrooms of this age often have ceramic tile over ordinary drywall around the tub, with no waterproofing behind it. Soft walls and loose tiles are a sign that water has been getting through.
Mississauga has a large stock of condominium townhouses and apartment towers, particularly around the City Centre. Bathrooms in both are compact, and in a condo the drains tie into a shared stack, so fixtures generally stay in place. The condominium corporation’s approval is needed before work starts, and water shut-offs have to be booked through the building. See condo renovation.
In the lakeside neighbourhoods, bathroom projects are often part of a wider renovation and sit in the premium tier: curbless showers, freestanding tubs, and custom vanities. In the newer subdivisions the usual project replaces builder-grade tub surrounds and vanities within the existing layout.
The City’s page on when a building permit is required says:
No permit needed: replacing a fixture, such as a sink, tub, toilet, or shower, in the same location.
Permit required:
We prepare the drawings and manage the application where one is needed. Electrical work, including heated floors, is inspected separately through the Electrical Safety Authority.

As a starting guide, a bathroom renovation in Mississauga runs from about $12,000 to $20,000 for an essential update with fixtures in the same place, $20,000 to $35,000 for a mid-range rebuild with a custom shower, and $35,000 to $70,000 or more for a premium bathroom with a new layout. Exact pricing follows a free consultation and site visit. These are average market prices and can be lower or higher depending on your preferences.
Only if fixtures change position or number. The City of Mississauga does not require a building permit to replace a sink, tub, toilet, or shower in the same location. A permit is required to add, remove, or relocate one of those fixtures, and to install, replace, or repair plumbing drainage.
It depends on the plumbing. Replacing a fixture in the same location is exempt under the City of Mississauga's list, but a permit is required when a fixture is removed or relocated or when drainage is altered. A tub-to-shower conversion usually changes the drain, so confirm with the City's building department before starting. We check this as part of the design.
Yes. Adding plumbing fixtures and finishing a basement both require a City of Mississauga building permit. If the bathroom is part of a basement apartment, the second unit must also be registered with the City.
Across the industry, a full bathroom rebuild typically takes two to four weeks on site once materials have arrived, and longer when fixtures move or a permit is involved. TODO: owner to confirm Calico's typical bathroom timeline.
