What's the total cost of removing a garden tub and tiling the space in a Calgary ensuite?

Removing a garden tub and tiling the space typically costs $3,500-$8,000 in Calgary, depending on the size of the area, tile selection, and whether you're creating a shower or simply a tiled alcove. This project involves demolition, plumbing modifications, waterproofing, and tile installation — all requiring professional expertise.

Demolition and removal of the garden tub runs $400-$800, including disposal fees. Garden tubs are heavy (300-500 lbs when empty) and often require cutting into sections for removal through doorways. The demolition crew will also remove surrounding tile or wall materials down to the studs, adding $200-$500 depending on the extent of existing finishes.

Plumbing modifications are the next major cost component. If you're converting the space to a walk-in shower, the existing tub drain will likely need relocation to meet shower floor slope requirements — budget $800-$1,500 for drain relocation and rough plumbing. The tub faucet plumbing can often be reused for a shower valve, but upgrading to a thermostatic mixing valve (recommended for safety) adds $300-$600. If you're simply tiling over the space without creating a shower, minimal plumbing work is needed, reducing costs significantly.

Waterproofing is absolutely critical for this project, especially if creating a shower area. Calgary's chinook temperature swings stress waterproofing systems, making quality membrane installation essential. A Schluter Kerdi waterproofing system for the alcove area costs $300-$800 in materials, with installation adding $500-$1,200. Never skip waterproofing in any wet area — water damage from failed waterproofing can cost $15,000-$30,000 to remediate.

Tile installation represents the largest variable in project cost. For a typical garden tub alcove (roughly 60 square feet of wall area plus 15 square feet of floor), expect these Calgary pricing ranges: ceramic tile runs $15-$20 per square foot installed, porcelain tile costs $18-$25 per square foot installed, and natural stone ranges from $25-$45 per square foot installed. Large-format tiles (24x24 or larger) create a modern look with fewer grout lines but require perfectly flat substrate preparation, adding $3-$5 per square foot to installation costs.

Additional considerations include electrical work if adding shower lighting or an exhaust fan ($300-$800), cement backer board installation behind all tile surfaces ($200-$400), and potential structural modifications if the tub was supporting wall elements ($500-$2,000). Calgary's hard water makes choosing the right grout crucial — epoxy grout resists staining and mineral deposits better than standard cement grout, though it costs 30-40% more.

Permit requirements depend on the scope of plumbing changes. Simple tub removal with minimal plumbing modifications typically doesn't require permits, but converting to a shower with drain relocation requires a City of Calgary plumbing permit ($75-$150). Your contractor handles the permit application and coordinates required inspections.

Timeline for this project runs 5-10 working days: 1 day for demolition, 1-2 days for plumbing rough-in, 1 day for waterproofing, 2-3 days for tile installation, and 1-2 days for grouting and finishing. Allow extra time in winter months when contractors may face weather delays for material deliveries.

This project requires professional installation — the combination of plumbing modifications, waterproofing, and tile work in a wet area demands expertise. Improper waterproofing or tile installation can lead to water damage, mould growth, and costly repairs within 2-5 years.
