Bathroom remodeling is the second-most-common Ottawa renovation behind kitchens, and the project where contractor selection matters most. The work hides behind tile and drywall: a bathroom remodeled by a contractor who skips the waterproofing membrane, mis-slopes the shower floor, or under-vents the room will look beautiful for 18 months and then start failing — and the cost to remediate is typically 2-3x the cost of doing it right the first time. This page covers what to expect from a quality Ottawa bathroom remodeling contractor, current 2026 cost ranges by bathroom type, the technical detai...
A professional Ottawa bathroom remodel moves through three phases: design and material selection, permitting and procurement, then on-site construction. Rushing the first two phases is the single biggest cause of mid-project delays, change orders, and blown budgets, because custom vanities, quartz tops, and frameless shower glass routinely carry four to twelve week supplier lead times in the Ottawa market. A disciplined contractor confirms every selection in writing, locks pricing, and stages ma...
Budget one to three weeks for measuring, layout, fixture selection, and a fixed-scope written quote. If you relocate plumbing fixtures, add an electrical circuit, or build an entirely new bathroom, the contractor pulls a City of Ottawa plumbing or building permit through the city online client porta...
A full gut typically runs demolition over one to two days, plumbing and electrical rough-in over two to four days, then insulation and cement-board or foam backer board on the wet walls. Next comes the continuous waterproofing membrane with a flood test on the shower pan, tile setting over three to ...
In 2026, Ottawa powder rooms generally run 4,500 to 18,000 dollars, main bathrooms 10,000 to 45,000, ensuites 22,000 to 90,000, and new basement bathrooms 9,500 to 28,000. Where your project lands depends on tile area, fixture grade, whether plumbing moves, and the quality of the waterproofing and glass. Always carry a ten to fifteen percent contingency, because Ottawa older homes routinely hide surprises behind old tile and drywall, from rotted subfloor to undersized drains.
Collect at least three written, line-itemized quotes and compare scope rather than the bottom-line number. A quote that comes in thousands of dollars cheaper almost always excludes the waterproofing membrane, proper exterior-vented exhaust, or carries tile and fixture allowances that are unrealistic...
Labour and tile setting are usually the largest line items in a tiled Ottawa bathroom, followed by cabinetry, shower glass, and plumbing fixtures. Moving a toilet drain, converting a tub to a curbless walk-in shower, or adding a steam unit meaningfully increases the plumbing and waterproofing budget...
Before you sign anything, verify the contractor credentials and confirm how the finished work is protected. Ottawa freeze-thaw climate, its older housing stock, and the variety across its neighbourhoods all shape both your risk profile and the best time of year to start.
Require proof of at least two million dollars in commercial general liability insurance and a current WSIB clearance certificate, verified directly through the WSIB website rather than a PDF the contractor forwards. Confirm that a licensed plumber and an ESA-licensed electrician personally perform t...
Ottawa humid summers and dry, heated winters make an exhaust fan ducted fully to the exterior essential, because venting into the attic causes condensation, frost, and mould in our cold climate. Century homes in the Glebe, Sandy Hill, and Old Ottawa South frequently hide knob-and-tube wiring, cast-i...
Powder room (2-piece): smallest bathroom, no shower or tub. Typical scope: vanity replacement, toilet swap, new flooring, paint, fixture upgrade. Half-day to 3-day projects. Main bathroom 3-piece (tub/shower combo): the workhorse Ottawa bathroom. Scope ranges from a 1-week refresh (paint, vanity, fixtures, accessories) to a 3-5 week gut renovation (full tile, new plumbing rough-in, custom shower glass). Main bathroom 4-piece (separate tub and shower): more common in 2000s+ Ottawa homes. Scope ex...
The technical details a quality Ottawa bathroom remodeling contractor will not skip: (1) Continuous waterproofing membrane (Schluter Kerdi, Wedi, RedGard) on all wet walls and shower floor — NOT cement board alone. (2) Properly sloped shower floor (1/4" per foot minimum to drain) with a true mortar bed pre-slope under the membrane, not just over it. (3) Code-compliant venting (typically a humidity-sensing exhaust fan with timer or dedicated VFD-controlled fan ducted to exterior, not just to the ...

Look for proven bathroom-specialty portfolio (not just general renovation), $2M+ insurance, WSIB clearance, licensed plumber and ESA-licensed electrician on the project, written warranty on waterproofing, and at least 3 recent Ottawa references. Ask specifically what waterproofing system they use and request a photo from their last project.
Yes for any work involving new plumbing rough-in, new electrical circuits, moving fixtures, or adding a new bathroom. Like-for-like fixture replacement (toilet for toilet, vanity for vanity in same location) usually doesn't require a permit. Adding a new bathroom always requires building, plumbing, and electrical permits via ESA.
Powder room: 3-10 days on-site. Main bathroom refresh: 5-10 days. Main bathroom gut: 3-5 weeks. Primary spa ensuite: 5-8 weeks. Basement bathroom new construction: 4-6 weeks. Add 2-8 weeks for permits, design, and material lead.
Continuous waterproofing membrane (Schluter Kerdi, Wedi, RedGard) behind all tile and on the shower floor over a properly sloped pre-slope. Cement board alone is NOT waterproofing. A contractor whose quote doesn't reference the waterproofing system is the wrong contractor.
