Is a Vancouver cast iron tub worth keeping?

Cast iron tubs in Metro Vancouver are often worth keeping — but only if they pass a few key tests. A well-maintained cast iron tub is one of the most durable fixtures ever made, and refinishing a good one is almost always cheaper than replacing it. The decision comes down to condition, layout goals, and what you're trying to achieve with your bathroom renovation.

What Makes Cast Iron Worth Saving

Cast iron tubs — common in Vancouver homes built before the 1960s, particularly in Kitsilano, Dunbar, Strathcona, and East Vancouver — were built to last generations. The porcelain enamel surface, when intact, is non-porous, easy to clean, and highly resistant to mould. The thermal mass of cast iron keeps bathwater warm far longer than acrylic or fibreglass. A quality cast iron tub in good condition has genuine value that a $400 acrylic alcove tub simply cannot replicate.

The critical question is the condition of the enamel surface. Run your hand across the bottom of the tub. If the surface feels smooth and glassy with no chips, cracks, or rough patches, the tub is a strong candidate for refinishing. Minor chips and surface dulling are repairable. If the enamel is heavily crazed (a network of fine cracks across the surface), deeply chipped down to bare metal with rust staining, or if the tub has been previously refinished with a peeling coating, replacement becomes more practical.

The Refinishing Option

Professional cast iron tub refinishing in Metro Vancouver typically costs $400–$800 and, when done properly, restores the surface to near-original condition with a lifespan of 10–15 years before the next refinishing. This compares very favourably to replacing the tub — a new alcove tub installation runs $1,500–$4,000 including removal, plumbing connections, and surround work. Removing a cast iron tub also requires significant labour; these tubs weigh 150–250 kilograms and often need to be cut into sections to exit the bathroom, adding $300–$600 in removal costs alone.

One important caveat: refinishing quality varies enormously between contractors. A proper refinish involves acid etching, bonding primer, and a catalyzed topcoat — not a spray-can DIY kit. Ask any refinisher about their process, the products they use, and how long the cure time is before the tub can be used.

When Replacement Makes More Sense

There are legitimate reasons to replace even a structurally sound cast iron tub. If your renovation involves a tub-to-shower conversion — one of the most common projects in Metro Vancouver as homeowners prioritize shower space over rarely-used baths — the tub goes regardless of condition. If you're reconfiguring the bathroom layout and the tub's drain location needs to move, you're already doing significant plumbing work that makes replacement more logical. And if the tub surround tile is being fully replaced anyway, the incremental cost of tub replacement is lower than it would be as a standalone project.

Asbestos awareness is important here: if your home was built before 1990 and you're planning any demolition around the tub — particularly removing old floor tiles, wall materials, or pipe insulation — test suspect materials before disturbing them. Pre-1990 bathroom materials in Metro Vancouver homes commonly contain asbestos, and professional abatement is required if it's found.

The Practical Verdict

If your cast iron tub has solid enamel, fits your layout, and you're doing a cosmetic bathroom refresh rather than a full gut renovation, refinish it. The quality, weight, and heat retention of a cast iron tub is genuinely superior to most modern replacements at the same price point. If you're doing a full renovation with layout changes, or converting to a shower, plan the removal into your project budget and account for the labour involved in getting a 200-kilogram tub out of a second-floor bathroom.
