How much does it cost to retile a shower and bathroom floor in Calgary?

Retiling a shower and bathroom floor in Calgary typically costs $4,000 to $10,000 for a standard bathroom, with the wide range depending on tile selection, shower size, demolition complexity, and whether any plumbing or waterproofing issues are discovered behind the old tile. A straightforward retile using mid-range porcelain tile in a typical bathroom with a 30 to 35 square foot shower enclosure and a 40 to 50 square foot floor lands in the $5,500 to $7,500 range for most Calgary homeowners.

Here is how the costs break down across the major components. Demolition and disposal of old tile runs $500 to $1,500 depending on how the original tile was installed. Tile set over cement backer board removes more cleanly than tile applied directly to drywall or old mud beds, which require more labour and generate more debris. Calgary disposal fees for construction waste run $150 to $300 for a typical bathroom's worth of demolished tile and backer board.

Substrate preparation and waterproofing is the most critical phase and costs $800 to $2,000 for the shower area. Once old tile is removed, the underlying surface must be inspected for water damage, mould, and structural integrity. In many Calgary homes built in the 1970s through 1990s, the original shower was not properly waterproofed — it is common to find moisture damage, soft spots in the framing, or mould growth behind the old tile. Repairing water-damaged framing adds $300 to $800 in unexpected costs. New cement backer board costs $1.50 to $3 per square foot, and a proper waterproofing membrane — either Schluter Kerdi sheet membrane at $3 to $6 per square foot or RedGard liquid membrane at $1 to $3 per square foot — is essential beneath all shower tile. Never allow a contractor to tile directly over drywall or skip the waterproofing membrane in a shower, regardless of what the previous installation looked like.

Tile materials and installation for the shower walls, shower floor, and bathroom floor represent the largest single cost. Using mid-range porcelain tile at $8 to $12 per square foot for materials, with installation labour at $10 to $15 per square foot, a combined 100 to 130 square feet of tile coverage costs $1,800 to $3,500 for materials and labour together. If you choose natural stone or large-format tile, both the material and labour costs increase — large-format tile requires more precise substrate flatness and more installation skill, while natural stone demands specialized thinset and sealing.

Grout, thinset, trim pieces, and finishing add $300 to $600 to the project. Given Calgary's hard water conditions, upgrading to epoxy grout adds $200 to $400 but dramatically reduces long-term maintenance. Tile edge trim, corner pieces, and a shower niche (if you are adding one) contribute to this category.

The shower floor specifically requires careful attention to slope — it must drain at 1/4 inch per foot toward the drain — and the drain assembly itself may need replacement if it is corroded or incompatible with the new waterproofing system. A new linear drain or centre drain assembly with installation runs $200 to $600.

Timing matters in Calgary's renovation market. Scheduling a retile project during the quieter winter months from November through March often means faster contractor availability and potentially more competitive pricing. The work is entirely indoors, so Calgary's cold weather does not affect the installation itself, though chinook temperature swings during curing can affect thinset and grout — your contractor should manage indoor temperature and humidity during the curing period.

Retiling a shower is not a DIY project. The waterproofing, slope requirements, and precision needed to prevent costly water damage make professional installation essential.
