How much does it cost to retile a standard bathroom in Ottawa including labour and materials?

A full bathroom retiling project in Ottawa typically costs $8,000 to $25,000 installed, with the wide range reflecting differences in bathroom size, tile selection, and whether you're retiling the floor, walls, shower surround, or all three.

Here's how costs break down for a standard 5-by-8-foot bathroom renovation:

Bathroom floor tile runs $8 to $25 per square foot installed (material plus labour). A 40-square-foot bathroom floor in mid-range porcelain tile with proper underlayment and leveling would cost roughly $1,200 to $3,000. If you're adding heated floor (enormously popular in Ottawa), add another $400 to $800 for the electric radiant mat and thermostat on top of the tile cost — the electrician's time to connect everything safely is separate and usually runs $400 to $800 for a straightforward installation.

Bathroom walls and shower tile cost $10 to $30 per square foot installed, including waterproofing. If you're retiling shower walls and a bathtub surround (roughly 120 to 150 square feet of wall area), expect $1,500 to $4,500 depending on tile type and finish level. High-end natural stone or large-format porcelain runs higher; standard ceramic or simpler porcelain runs lower.

A complete shower surround — floor, walls, niche, and curb — typically costs $2,000 to $7,000. This is where waterproofing costs are significant because proper shower waterproofing is non-negotiable in Ottawa. The waterproofing membrane itself adds $3 to $8 per square foot, but it's the difference between a beautiful shower that lasts 20 years and a water-damaged bathroom that costs $10,000 to $20,000 to remediate.

Tile material costs themselves vary dramatically based on your choices. Standard porcelain tile runs $3 to $8 per square foot. Mid-range to higher-end porcelain, including wood-look planks and more designer finishes, runs $8 to $15 per square foot. Natural stone (marble, granite, slate, travertite) runs $8 to $40 per square foot depending on the stone type. Basic ceramic tile is the budget option at $1 to $4 per square foot but is less durable than porcelain and not suitable for shower floors without heavy waterproofing.

Labour costs in Ottawa for 2025-2026 typically range $6 to $15 per square foot for straightforward tile installation, and $10 to $20 per square foot for complex work involving waterproofing, heated floors, or intricate patterns. Ottawa's labour rates run roughly 10 to 15 percent below Greater Toronto Area rates, which is one reason to love renovating here.

Additional costs that often surprise homeowners include subfloor leveling ($2 to $6 per square foot if your bathroom floor isn't perfectly flat — and most aren't), removal and demolition of existing tile ($3 to $8 per square foot), caulk and sealant for natural stone or premium finishes ($200 to $500), and grout sealing ($2 to $5 per square foot for professional application). If your shower needs a new waterproofing system, expect $3 to $8 per square foot just for the membrane material and installation.

The biggest cost variable in Ottawa bathroom retiling is tile selection. A bathroom using standard 12-by-24-inch porcelain tile in a simple colour will cost significantly less than one featuring large-format 24-by-48-inch porcelain, natural stone, or intricate mosaic patterns — not just because the materials are pricier, but because precision installation of large tiles takes longer and demands a perfectly flat substrate. Large-format tile in particular requires back-buttering (applying thinset to the back of each tile as well as the wall), which adds labour time.

Timing matters in Ottawa. Spring through fall is peak renovation season, and some contractors may quote slightly higher prices when they're busy. Late fall and winter can sometimes yield better rates, though winter work means slower adhesive curing times and requires climate-controlled conditions for proper drying.

Always get at least three written quotes that specify exact scope of work, tile materials (brand and style), waterproofing method, subfloor preparation approach, timeline, and warranty terms. A vague quote without these details is worthless for comparison. The cheapest quote is often cheap for a reason — it may skip crucial steps like proper waterproofing or subfloor leveling that will cost you thousands more later when problems emerge.
