Bathroom renovation · Oakville, Ontario
Calico Designs and Renovations renovates bathrooms in Oakville homes, from powder rooms and main bathrooms to full ensuite rebuilds. 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 of the room before work starts, and we handle Town of Oakville permits when fixtures move.

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.
Most Oakville houses have three or four bathrooms, built at the same time as the house and ageing at the same rate. Clients usually start with the one that bothers them most, and it is often the ensuite.
Two-storey homes from this period were built with large ensuites laid out around a corner soaker tub with a tiled deck, a small separate shower stall, and a long vanity with a single sink. The tub takes a third of the room and is rarely used.
The usual renovation removes the tub deck, builds a large walk-in shower in its place, adds a double vanity, and sometimes fits a freestanding tub where the old shower stood. Because fixtures move, this needs a Town of Oakville permit.
Bungalows and side-splits from the 1950s to the 1970s typically have one compact main bathroom, about 1.5 by 2.4 metres, with a cast-iron tub, wall tile set in mortar, and a small window in the tub wall. They are well built and hard to demolish.
Here the layout usually stays and everything else is renewed: plumbing behind the walls, a new tub or a walk-in shower, proper waterproofing, an exhaust fan ducted outside, and a vanity with real storage. Old galvanized supply lines and cast-iron drains are replaced while the walls are open.
Bathrooms were often added to these houses long after they were built, and fitted in wherever they would go. Floors may slope, joists may have been notched for old plumbing, and nothing is square. These projects need more investigation at the start and benefit most from a full rebuild.
Sound layouts with builder-grade finishes: acrylic tub surrounds, cultured marble tops, and basic tile. Projects here are usually an upgrade within the existing layout, which keeps them in the essential or mid-range tier and generally clear of permits.
From the Town’s guidance on interior alterations:
Typically no permit: replacing existing sinks, faucets, toilets, and cabinetry, and cosmetic changes to surfaces.
Permit required:
Permit drawings must show an exhaust fan for every washroom, and adding fixtures requires a water service sizing form. A new bathroom in a basement falls under the Town’s finished basement requirements. We prepare the drawings and manage the application.
Electrical work, including heated floors and new lighting circuits, is inspected separately through the Electrical Safety Authority.
In Oakville’s four heritage conservation districts, heritage review concerns the exterior. A bathroom renovation is affected only if it changes a window or another exterior feature.

As a starting guide, a bathroom renovation in Oakville 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.
Not if fixtures stay where they are. The Town of Oakville says replacing existing sinks, faucets, and toilets and making cosmetic changes does not typically require a permit. A building permit is required when plumbing fixtures are added or relocated, when walls are removed, or when a window is added or enlarged. Adding fixtures also requires the Town's water service sizing form.
Often, yes, by taking space from a walk-in closet or an adjoining bedroom. Moving walls and relocating the toilet, tub, or shower needs a Town of Oakville building permit. A 3D rendering shows whether the new layout works before any wall is touched.
Yes. Adding plumbing fixtures requires a Town of Oakville building permit, and so does finishing a basement. If the builder left a rough-in, the drains are already under the floor, which lowers the cost.
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.
