What is the cost to install a decorative tile border around a bathroom mirror in Ottawa?

A decorative tile border around a bathroom mirror typically costs $300 to $800 installed in Ottawa, depending on the tile type, border design complexity, and mirror size. For a standard bathroom mirror (roughly 24 x 36 inches), you're looking at the lower end of that range — around $300 to $500 — while a larger or more intricate decorative border with specialty tile or custom patterns can easily reach $700 to $1,200.

The cost breaks down into two main components: materials and labour. Decorative tile borders are usually made from ceramic, porcelain, or natural stone in smaller format sizes — mosaic tiles, listello strips (decorative border tiles), or hand-cut pieces. Material costs for decorative border tile run $3 to $15 per linear foot depending on whether you're using standard ceramic ($3 to $5 per linear foot), porcelain ($4 to $10 per linear foot), or premium natural stone or hand-painted tile ($8 to $20 per linear foot). A typical bathroom mirror border requires 8 to 12 linear feet of tile, so materials alone will be $25 to $180. Labour to remove the existing mirror (if necessary), prepare the wall, set the decorative tile, grout, and caulk the perimeter typically runs $200 to $600 depending on the installer's rates and whether any wall preparation or substrate repair is needed first.

Ottawa installers generally charge $12 to $18 per linear foot for decorative border installation, which includes cutting, setting, grouting, and sealing where needed. If your wall is uneven or requires leveling, patching, or primer before tile installation, that adds another $100 to $300 to the project cost. The mirror itself is usually removed temporarily during the border installation and reinstalled afterward — if the mirror needs new mounting hardware or a new frame as part of the refresh, that's an additional cost outside the tile work itself.

One important consideration: bathroom mirrors are often installed directly over drywall in older Ottawa homes, and drywall is a poor substrate for tile because it's soft, water-absorbent, and not designed to support tile weight. Before tile is installed around a mirror, the wall should be primed or sealed to prevent moisture damage, and any drywall that will be directly behind the tile should ideally be replaced with cement board (Durock) in the areas where water splash or humidity is a concern. This adds $50 to $150 to the project but prevents long-term moisture problems. Bathroom humidity is relentless in Ottawa's freeze-thaw climate, and cutting corners on substrate preparation in a bathroom is false economy.

If you're doing a mirror border update as part of a larger bathroom renovation or refresh, bundling it with other tile work — like a new backsplash around the vanity or re-tiling the floor — often brings the per-square-foot cost down slightly because the installer is already mobilized on the project. A decorative border is also a perfect project for a capable DIY installer if you're comfortable with basic tile-setting skills — it's a small, forgiving area with straightforward geometry, and mistakes are easier to correct than on a large floor or shower surround.
