Tile is one of the few Ottawa renovation finishes where the difference between a good installer and a cheap one stays hidden until it fails. A backsplash forgives small errors, but a shower or a heated bathroom floor punishes them: skip the waterproofing membrane, mis-slope the pan, or set tile over deflecting subfloor and you will see cracked grout, loose tiles, and mould within two or three Ottawa winters. Our freeze-thaw climate, humid summers, and dry heated winters put constant stress on tile assemblies, especially at entryways, mudrooms, and unheated sunrooms. This page explains what pro...
A dedicated Ottawa tile contractor handles far more than sticking tile to a wall. The core services are floor tiling for kitchens, bathrooms, entryways, and basements; full waterproofed shower and tub surrounds; kitchen and bar backsplashes; heated-floor systems layered under porcelain or stone; and specialty work such as large-format porcelain slabs, mosaic feature walls, and natural stone. Good setters also prepare the substrate — installing cement board, uncoupling membranes like Schluter Dit...
The substrate is where quality is won or lost. On floors, a proper installer checks joist deflection (the industry target is L/360 for ceramic and L/720 for natural stone) and adds plywood or an uncoupling membrane to prevent grout cracks over Ottawa's seasonally moving wood framing. In wet areas, t...
In 2026, Ottawa tile installation labour typically runs $8–$16 per square foot for standard porcelain or ceramic floor tile, $14–$25 per square foot for showers and wet walls because of the waterproofing and detailing involved, and $12–$22 per square foot for backsplashes where cuts around outlets, windows, and cabinets slow the work down. Large-format tile (24x48 and up), natural stone, herringbone, and intricate mosaic patterns push labour toward the top of those ranges or beyond, often $20–$3...
Three factors move an Ottawa tile quote the most: tile size and pattern, substrate condition, and waterproofing scope. Small mosaics and large-format slabs both cost more per square foot than standard 12x24 porcelain — the first because of the sheer number of cuts, the second because of the equipmen...
A professional Ottawa tile job follows a predictable sequence, and rushing it is the leading cause of callbacks. First comes protection and demolition of any existing tile, then substrate assessment and repair — plywood, cement board, self-levelling, or uncoupling membrane as needed. Wet areas then receive waterproofing and, for showers, a flood test that must sit for 24 hours to confirm the pan holds water. Layout is dry-fit and snapped with laser lines so cuts fall in balanced, symmetrical pos...
Tile itself is a finish and does not require a standalone permit, so a straightforward backsplash, floor re-tile, or tub-surround replacement can proceed without City of Ottawa paperwork. Permits enter the picture when the tile work is part of a larger project that touches structure, plumbing, or electrical. Moving a shower drain, converting a tub to a curbless walk-in shower, or adding a new bathroom triggers a City of Ottawa plumbing permit and inspection before walls close. Heated tile floors...
Tile is a trade where the portfolio and the process reveal everything. Ask to see recent Ottawa showers and heated floors — not just backsplashes — and request photos taken during waterproofing, before tile hid the work. Any competent setter will happily show membrane and flood-test photos. Confirm they carry at least $2 million in general liability insurance and a valid WSIB clearance certificate, verified directly on the WSIB site. Ask which waterproofing system they use by name and whether th...
You can trim a tile budget without inviting failure. Choose a mid-range rectified porcelain in a common 12x24 size and a simple offset or straight layout — you avoid both the per-tile premium of mosaics and the handling premium of oversized slabs. Keep the existing layout so plumbing and drains stay put, which avoids permit-triggering relocations. Do your own demolition and old-tile disposal if you are handy, since removal is labour, not skill. Buy tile during Ottawa retailer clearance events or...
Labour typically runs $8–$16 per square foot for standard floor tile, $14–$25 for waterproofed showers, and $12–$22 for backsplashes. Large-format and natural stone push higher. Per job, expect $900–$2,500 for a backsplash and $3,500–$9,000 for a full custom shower, plus tile materials at $3–$30-plus per square foot.
Tile itself needs no permit, but if you move the drain, convert a tub to a walk-in shower, or add a bathroom, you need a City of Ottawa plumbing permit and inspection. Heated tile floors require an ESA electrical permit for the dedicated GFCI circuit. Like-for-like re-tiling generally needs no paperwork.
A continuous waterproofing membrane — Schluter Kerdi, Wedi, or a liquid membrane like RedGard — over cement board or foam backer, with a sloped mortar pre-slope and a flood-tested pan. Cement board alone is not waterproof. If a contractor cannot name their system or show flood-test photos, their shower will eventually leak.
A backsplash typically takes one to two days, a tiled tub surround two to three days, and a fully waterproofed custom shower four to seven days including waterproofing cure and a 24-hour flood test. Floors depend on area and substrate prep. Plan for the room to stay out of use during grout cure.
Sometimes on sound, flat floors, but it is rarely ideal. Tiling over old tile raises floor height, complicates transitions, and hides substrate problems common in older Ottawa homes. In wet areas, never tile over old tile or drywall. A proper installer assesses deflection and substrate condition before recommending an overlay versus full demolition.
