How Much a Bathroom Remodel Costs in Ottawa in 2026

A full remodel of a standard Ottawa bathroom (roughly 5 by 8 feet, gutted to the studs, mid-range finishes) typically runs between $20,000 and $40,000 before HST. A cosmetic refresh that keeps the tub, toilet and layout can come in closer to $10,000 to $20,000, while a larger primary ensuite with a custom tile shower and double vanity often starts around $40,000 and can pass $75,000.

These are typical market ranges for the Ottawa area, not a quote. The real number for your room depends on its size, what is hiding behind the walls, whether anything moves, and the finishes you pick. Here is how to read those ranges and where the money goes.

Three common project levels

Cosmetic refresh ($10,000 to $20,000). New vanity and faucet, new toilet, paint, a new light fixture and exhaust fan, and sometimes a new floor. The tub and surround stay, or the tub gets a new acrylic wall system. No walls come down and the plumbing stays where it is. This suits a bathroom that works fine but looks tired.

Full remodel, same layout ($20,000 to $40,000). Everything comes out down to the studs and subfloor. New supply lines and drains where needed, a waterproofed tub or shower area, new tile, vanity, toilet, lighting, ventilation and drywall. The sink, toilet and tub stay in the same spots, which keeps the plumbing cost under control. Most Ottawa bungalows, split-levels and townhouses fall in this band.

Ensuite or layout change ($40,000 and up). A primary bathroom where the tub becomes a walk-in tiled shower, a second sink is added, the toilet moves, or a wall shifts to borrow space from a closet. Moving drains in a slab or between floor joists, adding heated floors and choosing frameless glass all push the total higher.

Where the money goes in an Ottawa bathroom

A full remodel quote usually breaks down into a handful of buckets. Labour is the largest share, often close to half the total, because a bathroom packs plumbing, electrical, carpentry, waterproofing, tile and finishing into a very small room.

• Demolition and disposal. Removing tile, tub, drywall and fixtures, plus a bin or haul-away. Older homes in neighbourhoods like Westboro, the Glebe or Alta Vista sometimes have mortar-bed tile or plaster walls, which take longer to remove.
• Plumbing. New shut-off valves, supply lines, a new shower valve and drain work. Relocating a fixture adds cost quickly.
• Electrical and ventilation. A properly sized exhaust fan ducted outside, GFCI protection near water, new lighting and sometimes a dedicated circuit for heated floors.
• Waterproofing and tile. A membrane behind the shower walls and under the floor in wet areas, then tile setting. Large-format porcelain and intricate patterns cost more to install than standard sizes.
• Fixtures and finishes. Vanity, countertop, toilet, faucets, shower glass, mirror and accessories. This is the bucket with the widest spread, since a vanity can cost a few hundred dollars or several thousand.

Permits in Ottawa

Swapping a vanity, toilet or tile in the same location generally does not need a building permit. The City of Ottawa does require a permit when plumbing is added or relocated, when walls that carry load are removed or altered, or when the work changes the structure of the house. Electrical work in Ontario falls under the Electrical Safety Authority (ESA), and a licensed electrical contractor files the notification for the work.

Permit fees themselves are a small part of the budget, but the inspections add scheduling steps. A good quote says which permits are needed and who pulls them. If a contractor suggests skipping a required permit, that is worth questioning, since unpermitted plumbing changes can come up later when the house is sold.

Things that raise the price

• Hidden damage. Rotted subfloor around the toilet or tub is common in older houses, especially where a shower leaked for years. Most quotes carry a contingency line or a per-square-foot rate for subfloor repair.
• Moving the toilet or shower drain. Even a short move can mean opening the ceiling below or cutting a concrete slab in a basement bathroom.
• Curbless showers. A zero-threshold entry needs the floor recessed or built up so the water still runs to the drain.
• Heated floors, niches and benches. Each one is a reasonable upgrade, and each adds labour and materials.
• Condo rules. Ottawa condo buildings often limit work hours, require floor protection in hallways, and ask for proof of insurance from the trades before work begins. Some require an acoustic underlayment under new tile. That time and paperwork shows up in the price.
• Basement bathrooms. Adding a bathroom where none existed may need a sewage ejector pump if the drain sits below the main sewer line.

Ways to keep the total down

Keep the layout. Leaving the toilet, sink and tub or shower where they are is the single biggest saving in most bathrooms. Choose standard tile sizes over large slabs or mosaics. Consider a quality acrylic or solid-panel shower surround instead of floor-to-ceiling tile if the bathroom is a secondary one. A stock vanity in a standard width installs faster than a custom piece. And decide on finishes before work starts, because changes once the walls are open cost time and money.

HST and the timing question

Prices in quotes are usually shown before tax, and Ontario's 13% HST applies to both labour and materials. On a $30,000 project that is another $3,900, so build it into the budget from the start.

Late fall and winter are a sensible time to plan a bathroom in Ottawa. Interior work is not affected by weather, and booking a contractor before the spring rush can make scheduling easier. Expect a full remodel of a standard bathroom to take roughly three to five weeks once work begins, longer if custom glass or special-order tile has a lead time.

If accessibility is part of the goal, look at the federal Home Accessibility Tax Credit, which can apply to eligible renovations that make a home safer or easier to use for a senior or a person with a disability.

Frequently asked questions

How long does a bathroom remodel take in Ottawa?

A full remodel of a standard bathroom usually takes three to five weeks of work once demolition starts. Permit inspections, custom glass and special-order tile can stretch that. A cosmetic refresh that keeps the tub and layout is often done in one to two weeks.

Does a bathroom renovation in Ottawa need a permit?

Replacing fixtures and finishes in the same location generally does not need a building permit. Adding or moving plumbing, or changing walls and structure, does need one from the City of Ottawa. Electrical work is handled through the Electrical Safety Authority by a licensed electrical contractor.

Is it cheaper to convert a tub to a shower?

A tub-to-shower conversion on its own often costs less than a full remodel, because the rest of the room can stay as it is. The price depends on whether you choose a prefabricated base and panels or a custom tiled shower, and whether the drain needs to move. Glass doors and grab bars add to the total.

How much contingency should a bathroom budget include?

Setting aside 10 to 15 percent of the project cost is a common rule of thumb for a full remodel, more for an older house. Water damage under the floor and outdated wiring are the usual surprises. A detailed quote will say how those situations are priced if they come up.
