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...
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 ...

Five vetting questions that filter out the wrong contractors: (1) What waterproofing system do you use behind tile, and can you show me a photo from your most recent install? Quality answer: Schluter Kerdi, Wedi, or RedGard, with confident reference to a recent project. (2) Who pulls and signs the permit? Quality answer: We do, and the inspection schedule is part of our project plan. (3) What's the warranty on your tile and waterproofing work specifically? Quality answer: 2-5 years on workmanshi...
(1) Choosing the lowest quote: the lowest quote almost always cuts the waterproofing membrane, the proper backer board, or the licensed-trade hours. (2) Not allowing for hidden conditions in pre-1980 Ottawa homes: galvanized supply pipes, knob-and-tube wiring, cast-iron drain stack, asbestos in tile mastic or wall board, lead solder. Budget a $3,000-$10,000 contingency for older home discovery. (3) Skipping the permit: like-for-like fixture replacement doesn't require a permit, but anything invo...
Median project pricing: powder room $4,500-$18,000, main bathroom $10,000-$45,000, ensuite $22,000-$90,000, basement bathroom $9,500-$28,000. Contractor management fee is typically 15-20% built into the line items. See our bathroom remodel cost guide for detailed line-item breakdowns.
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.
