Should I refinish or replace my old bathtub in a Vancouver bathroom renovation?

If your existing tub is structurally sound — no cracks, no rust-through, and the drain and overflow are functional — refinishing is a cost-effective option that buys you 7–15 years of renewed life at roughly one-third the cost of full replacement. However, if your renovation involves moving plumbing, changing the bathroom layout, or the tub has structural damage, replacement is the better long-term investment.

Bathtub refinishing (also called reglazing or resurfacing) involves cleaning, etching, priming, and spraying a new coating over the existing tub surface. In Metro Vancouver, professional bathtub refinishing costs $350–$700 for a standard alcove tub, with the work completed in 4–6 hours and the tub ready for use within 24–48 hours. The process works well on cast iron, enamelled steel, and fibreglass tubs. A quality refinishing job by an experienced technician creates a smooth, glossy surface that looks like a new tub and resists staining and mould growth. The best refinishers use a two-part polyurethane or aliphatic acrylic-urethane coating that bonds chemically to the prepared surface.

Refinishing makes the most sense when your bathroom renovation is cosmetic — new tile, vanity, toilet, and fixtures — with the tub staying in its current location on existing plumbing. It is also the obvious choice for Vancouver character homes where the original cast iron tub is a design asset. A well-maintained 1920s cast iron clawfoot tub, professionally refinished, is often more desirable than a brand-new acrylic replacement. Refinishing preserves the character of the home and avoids the floor damage risk and plumbing complications of removing a 300-pound cast iron tub from a heritage bathroom.

The limitations of refinishing are real, though. The new coating is a surface layer, typically 1–2 millimetres thick, applied over the original enamel or surface. It is more susceptible to chipping from dropped bottles or abrasive cleaners than the original factory finish. Harsh chemical drain cleaners will damage the refinished surface — use enzymatic drain cleaners only. In Metro Vancouver's humid climate, the edges where the refinished surface meets caulking lines need careful maintenance; if moisture gets under the coating through a chip or poor caulking, the coating can peel and blister. Most professional refinishing companies offer a 3–5 year warranty, with the coating lasting 7–15 years with proper care.

Full bathtub replacement is the right choice when any of these conditions apply: the tub has structural cracks or rust-through (common in enamelled steel tubs after 20–30 years), the drain or overflow assembly is corroded beyond repair, you are changing the bathroom layout and relocating plumbing, you want to convert from a tub to a walk-in shower or upgrade from an alcove tub to a freestanding soaker, or the tub is fibreglass that has become permanently stained or soft. Replacement costs in Metro Vancouver range from $1,500–$4,000 for a standard alcove tub swap (same location, same plumbing) to $3,000–$8,000+ for a freestanding tub installation with drain relocation and new faucet.

There is also a hidden cost calculation to consider. If your bathroom renovation budget is $15,000–$30,000 for a mid-range gut renovation, spending $400–$600 to refinish rather than $2,500–$4,000 to replace frees up $2,000–$3,400 that you can redirect toward better tile, upgraded fixtures, proper waterproofing, or a higher-quality vanity — areas that have a bigger impact on the daily experience and long-term durability of the bathroom.

One important caution: DIY bathtub refinishing kits sold at hardware stores for $30–$80 are not comparable to professional refinishing. These kits use inferior coatings that peel within months, especially in Vancouver's humid bathroom environments. They also require etching the tub surface with acid, which produces dangerous fumes in an enclosed bathroom. Professional refinishing uses spray equipment, proper ventilation, and commercial-grade coatings that are not available to consumers. This is a case where the professional result is dramatically better than DIY.

For condos and strata properties in Metro Vancouver, refinishing has the added advantage of minimal disruption — no heavy demolition, no hauling a tub through common hallways, no risk of water damage to units below, and no extended construction timeline. Many strata councils look more favourably on refinishing than full tub replacement because the liability and disruption risks are substantially lower.
