How much does a bathtub replacement cost in Calgary?

A standard bathtub replacement in Calgary typically costs between $1,500 and $4,500 all-in, depending on the type of tub, the complexity of the plumbing, and whether surrounding tile or walls need repair. A basic alcove acrylic tub replacement where the new tub drops into the same footprint as the old one sits at the lower end, while upgrading to a freestanding soaker or reconfiguring plumbing pushes costs significantly higher.

The tub itself is only part of the equation. A standard acrylic alcove tub runs $300 to $800 for the unit, while a freestanding soaker tub ranges from $1,000 to $5,000+ depending on material and brand. Installation labour for a straightforward swap — removing the old tub, setting the new one, connecting the drain and overflow, and reconnecting the faucet — typically costs $500 to $1,200 in the Calgary market. However, most bathtub replacements involve additional work that drives the final price up. The tile surround around an alcove tub almost always sustains damage during removal, meaning you should budget $1,500 to $3,000 for new tile and waterproofing on the surrounding walls. If the subfloor beneath the old tub shows water damage or rot — which is common in Calgary homes built before the 1990s — subfloor repair adds $300 to $800.

Plumbing considerations are especially important in Calgary's climate. If your bathroom has plumbing running through or near an exterior wall, your contractor should verify that supply lines are properly insulated to prevent freezing during Calgary's harsh winters, when temperatures regularly drop to -25°C or colder. PEX piping is the preferred material for Calgary installations because it has slight flexibility to handle expansion if temperatures fluctuate rapidly during chinook events, which can swing 20 to 30 degrees in a matter of hours. If the existing drain and overflow connections are in good condition and the new tub aligns with the same rough-in dimensions, plumbing costs stay minimal. Relocating the drain or supply lines requires a plumbing permit from the City of Calgary, adding $75 to $200 in permit fees plus additional labour.

Calgary's hard water is another factor worth considering when choosing your new tub. Acrylic tubs resist hard water staining better than fibreglass and are easier to clean, making them the most popular choice in the Calgary market. Cast iron tubs with porcelain enamel are extremely durable but significantly heavier — verify that your floor structure can handle the weight before selecting one. If you are replacing a tub in an older Calgary home, have your contractor check the floor joists for adequacy, especially if you are upgrading to a heavier unit.

A like-for-like tub replacement using existing plumbing connections does not require a permit, but any plumbing relocation or structural modification does. Always verify that your contractor carries WCB Alberta coverage and general liability insurance before work begins. For a straightforward alcove tub swap, most Calgary contractors can complete the job in one to two days. If your project includes new tile, waterproofing, and finishing work, expect three to five days total. Get at least three quotes and ask to see completed bathtub replacement projects before hiring — the quality of the waterproofing and drain connection is critical to preventing leaks that cause expensive damage down the road.
