The best bathroom renovators in Ottawa are the contractors who can explain their waterproofing system in detail, use a licensed plumber for any drain or supply relocation, pull the City of Ottawa plumbing permit when required, and put the shower assembly — membrane, pre-slope, niche, and curb — in writing. Waterproofing is the one part of a bathroom you cannot inspect after the tile goes on, which is why it is the single best test of a contractor's quality. In 2026, expect a standard 5x8 Ottawa bathroom refit to run $15,000–$25,000, a mid-range renovation with a tiled shower to land at $25,000...
Ask every Ottawa bathroom contractor one question before anything else: what waterproofing system do you use, and how do you build the shower? A professional will answer without hesitation — a bonded sheet or liquid membrane system such as Schluter-KERDI, Laticrete HYDRO BAN, or an equivalent, applied over the correct substrate, with a sloped mortar bed or a pre-sloped tray, a properly bonded drain, waterproofed niche and curb, and a flood test before tiling. A weak contractor will say they use ...
A bathroom fan must exhaust outdoors, never into an attic or soffit. For most Ottawa bathrooms a 80–110 CFM fan on a timer or humidity sensor is appropriate, and insulated duct should be used through cold attic space to prevent condensation dripping back into the housing.
In 2026 Canadian dollars, a straightforward Ottawa bathroom renovation that keeps the existing layout — new tub or acrylic surround, toilet, vanity, flooring, lighting, and paint — typically runs $15,000–$25,000 for a standard 5x8 main bathroom. Step up to a fully tiled shower, a quality glass door, porcelain floor tile, and new fixtures and you are generally at $25,000–$35,000. A primary ensuite with a curbless tiled shower, freestanding tub, double vanity, heated floor, and relocated plumbing ...
A bathroom packs plumbing, electrical, ventilation, tile, waterproofing, and cabinetry into 40 square feet. The trade count, not the floor area, drives the price — which is why a tiny powder room can still cost $8,000–$14,000 to redo properly.
Swapping a vanity and toilet in place does not require a permit in Ottawa, but relocating or adding any plumbing fixture does — a plumbing permit from the City of Ottawa is required, and the work must be performed by a licensed plumber. Adding a new bathroom, particularly in a basement, almost always requires a plumbing permit and may require a building permit if framing changes are involved. Electrical changes such as adding a fan, pot lights, a heated floor circuit, or a receptacle require an ...
A realistic Ottawa bathroom renovation schedule is three to five weeks on site for a standard bathroom and five to eight weeks for a large ensuite with a curbless shower and heated floor. The sequence is demolition, plumbing and electrical rough-in, inspection, insulation and backer board, waterproofing membrane and flood test, tile, then fixtures, glass, and paint. Two steps regularly stretch the calendar: the inspection window, which must be booked and passed before walls close, and the glass ...
Tile, vanities, and specialty fixtures can be back-ordered for weeks. The best Ottawa renovators require all selections to be finalized and delivered to site before the first wall comes down, which prevents your bathroom sitting gutted while a tile shipment clears.
Shortlist three contractors and require each to quote the same fixture package and the same shower construction so the numbers are comparable. Verify WSIB clearance and general liability insurance, confirm the plumber's licence and the electrical contractor's ESA licence number, and check that the contract names the waterproofing system, the tile allowance, the fixture allowance, and who is responsible for permits. Ask to see two recent Ottawa bathrooms and, if possible, one that is at least two...
There is no official list. The best Ottawa bathroom renovators carry WSIB clearance and liability insurance, name their waterproofing system in the contract, use a licensed plumber and an ESA-licensed electrical contractor, pull the required City of Ottawa permits, provide milestone-based payments with a holdback, and can show bathrooms they completed two or more years ago. Compare three quotes on identical scope.
A standard 5x8 bathroom refit typically costs $15,000–$25,000, a mid-range renovation with a fully tiled shower runs $25,000–$35,000, and a large primary ensuite with a curbless shower and heated floor commonly runs $35,000–$60,000. A powder room usually costs $8,000–$14,000.
Replacing fixtures in the same location generally does not require a permit, but relocating or adding any plumbing fixture requires a City of Ottawa plumbing permit and a licensed plumber. Adding a new bathroom, especially in a basement, typically requires a plumbing permit and may need a building permit for framing changes.
A bonded sheet or liquid membrane system such as Schluter-KERDI or Laticrete HYDRO BAN over a proper substrate, with a sloped pan, a bonded drain, waterproofed niche and curb, and a flood test before tiling. Grout and green board are not waterproofing, and any contractor who says they are should be avoided.
Three to five weeks for a standard bathroom and five to eight weeks for a large ensuite. Rough-in inspection and custom glass shower doors — which need two to three weeks after tile is finished — are the two most common schedule extenders.
