A customer in Hawthorn last year had two quotes on her desk for the same bathroom. Quote one: $8,400 to replace the bath, including the tile retile, the plumbing, and the disposal. Quote two: $1,380 to resurface the existing bath. Her own words after the resurface was done: "thought I'd have to redo the whole bathroom. Saved me $7,000 for a result I cannot tell from new."
This is the comparison the bath-replacement quote almost never includes. Replacement is not a like-for-like swap. There is a knock-on chain of trades and damages that the bath-supplier quote does not list, and that turns a $1,200 bath unit into a $4,000 to $8,000 final bill in an existing bathroom. Resurfacing, in most cases, is one trade, one day onsite, and a fraction of the cost.
This post lays out the full apples-to-apples comparison so you can decide which is right for your bathroom.
When this comparison applies
Resurfacing vs replacement is the question when the bath itself is structurally fine, the surface has chips, cracks, dulled enamel, or you want a colour change. If the bath substrate is failing (rusted-through enamel, structurally cracked cast-iron, badly delaminated fibreglass), replacement is the only answer. We will say so when we see the photos.
For everything else, here are the numbers.
The resurfacing cost (Melbourne, 2025)
For a standard 1500 to 1700mm bath in an existing bathroom:
- Full bath resurface: $1,180 to $1,680
- Single chip repair only (not a full resurface): $280 to $480
- Resurface with colour change (white to another colour, or coloured to white): $1,280 to $1,820
- Resurface plus stripping old coating (previously resurfaced bath that has peeled): $1,480 to $2,200
Typical onsite time: around 4 hours for a standard resurface. Bath downtime: 24 to 48 hours cure time before use. Bathroom downtime: the bath is unusable during cure. The rest of the bathroom (toilet, vanity, shower) is fine to use throughout.
For freestanding cast-iron baths and unusually shaped tubs, add 15 to 30 per cent.
The coating itself, in normal use, lasts 10 to 15 years.
The replacement cost (Melbourne, 2025)
This is the full bill people are not quoted up front.
The bath unit: $400 to $1,200
Acrylic baths sit at the low end. Mid-range enamel-on-steel or stone-composite freestanding tubs sit at $800 to $1,200. Premium freestanding cast-iron or natural stone tubs go well over $2,000 on their own. The bath supplier quotes only this line.
Plumber: $600 to $1,400
Disconnecting the existing bath, removing the waste, removing the spout and mixer, lifting the bath out, setting the new bath, re-plumbing the waste and overflow, re-installing the spout and mixer, pressure-testing, and re-sealing. For most bathrooms this is a full day of plumber time.
Tiler: $1,400 to $4,200
This is the line most customers never see in the replacement quote until the tiler arrives.
When the bath comes out, the tile lip and the surrounding edge tiles almost always damage. The original tile work was laid up to the bath, not around it. Lifting the bath cracks or chips the tiles that were sealed against the rim. The standard practice is to retile the lip and at least one row of tiles up the wall behind the bath. If your tiles are no longer available (almost always the case for tiles over 5 years old), the only option is to retile a wider area to make the patch invisible.
For most Melbourne bathrooms, this means retiling a 1.5 to 3 square metre area, with new tile-match tiles and the labour to lay them. $1,400 if the tiles are matching and the area is small; $4,200 if you cannot match and the tiler ends up retiling the whole wall.
Waterproofing re-do: $400 to $800
The bath comes out, the waterproof membrane behind the tiles is partially damaged, and the new bath needs a fresh waterproof seal at the rim. The standard is to re-waterproof the bath surround before the new tile goes back. This is a separate trade.
Disposal: $80 to $200
Council pickup, skip bin, or trade dump fees for the old bath unit. Cast-iron baths cost more to dispose of because of weight.
Bathroom downtime: 5 to 14 days
This is the cost most quotes do not name. The bathroom is unusable from the day the plumber starts until the tiler finishes and the waterproofing cures. For a family with one bathroom, that means showering at a gym or a relative's place for a week or two. For a rental property, it means lost rent.
Total bath replacement: $2,880 to $7,800 in most Melbourne bathrooms.
For premium baths or unusual layouts, $10,000 or more is not unusual.
Side-by-side comparison
For a typical Melbourne bathroom with a standard acrylic or enamel-on-steel bath that has a few chips:
| Factor | Resurface | Replace | |---|---|---| | Total cost | $1,180 to $1,680 | $2,880 to $7,800 | | Onsite time | About 4 hours | 3 to 5 trade days | | Bathroom downtime | Bath unusable 24 to 48 hours | Whole bathroom unusable 5 to 14 days | | Tile damage | None | Almost always | | Plumbing rework | None | Yes (disconnect + reconnect) | | Trades involved | One (Surface Fix) | Three (plumber, tiler, waterproofer) | | Quotes to coordinate | One | Three to four | | Outcome | Bath looks new | Bath is new | | Insurance | Fully insured | Varies by trade |
For most homes, the resurface result is indistinguishable from a new bath in normal lighting. The bath body itself keeps its original lifespan; the coating holds up in normal use.
The cases where replacement is the right call
Three cases we tell customers honestly.
Case 1: The bath body is failing. Rust eating through enamel-on-steel. Structural cracks in cast-iron. Acrylic that has flexed and fatigued over 25+ years and is brittle. In these cases the surface coating will hold but the bath itself will fail within a few years. Replacement is the better long-term economic answer.
We can tell from photos. We will say so in the quote.
Case 2: You are renovating the bathroom anyway. If the bathroom is being gutted, the layout is changing, the tiles are being replaced, or you want a freestanding tub where a built-in tub used to sit, the bath is going anyway. Paying $1,380 to resurface a bath that is being ripped out next month is wasted money.
Case 3: The bath itself does not fit how the bathroom is used. A short bath for a tall person. A deep bath for someone who only takes showers. A built-in bath where a shower is now wanted. Resurfacing keeps the bath the same shape and size. If the shape is wrong, replacement makes sense.
We see these cases. We will tell you when one of them applies, not sell you a resurface that does not solve the actual problem.
What about colour change?
Resurfacing supports colour changes. White to almond, almond to white, mustard or avocado (common in 1970s baths) to white, dark tones to lighter tones. Add $100 to $150 for the extra coat needed for opacity on dramatic changes.
The opposite (white to a strong dark colour) is also possible but less common because resurface dark colours are harder to keep evenly polished over time. We recommend white, almond, biscuit, and light grey as the most reliable colour outcomes.
If you want a specific colour that is hard to match through resurface, replacement with a factory-coloured bath might be the better answer. Send a photo and we will say which path makes sense.
What good resurfacing workmanship looks like
A properly done bath resurface holds up in normal use. That comes down to:
- Adhesion. The coating staying bonded to the bath substrate.
- Surface integrity. No cracking, peeling, or bubbling under normal use.
- Colour stability. No yellowing, fading, or staining under normal cleaning products.
What shortens that: hot objects placed directly on the bath, abrasive cleaners (Jif, Ajax), drain unblockers used incorrectly on the surface, or removal of the bath for an unrelated renovation.
Real numbers from a recent comparison
A customer in Brighton last year:
- Replacement quote one (a kitchen and bathroom showroom): $9,200 for an "everything including tiles" package.
- Replacement quote two (plumber + tiler quoted separately): $6,800.
- Surface Fix resurface quote: $1,380.
- Outcome: customer chose resurface. We completed in one day. Bath has been in normal use for 14 months. The customer was happy with the result, and there have been no issues since.
That is the typical pattern. We are not the right answer for every bathroom. For most chip-damaged or surface-faded baths in structurally sound condition, we are.
Quote your bath
Send 1 to 2 photos through the form at surfacefix.com.au/quote. Include a wide shot of the bath in its bathroom context and a close-up of any specific damage. We come back with a written quote within 24 hours. If the photos show the bath body is failing and replacement is the better answer, we tell you that too.
FAQ
Will the resurface really last 7 years? The coating in normal residential use lasts 10 to 15 years. Rental and commercial use (e.g. holiday rentals with weekly turnover) sits at the lower end. We have resurfaces in Melbourne homes from 2018 that have had no issues.
What does a "real" resurface look like vs a cheap one? A proper resurface includes substrate prep (cleaning, sanding, repairing chips and cracks first), primer coat, three to four coats of top finish, oven-cured or chemical-cured to harden. A cheap resurface skips prep, applies one or two coats over a poorly prepared surface, and peels within 18 months. The price gap between a $600 bargain resurface and a $1,380 proper resurface comes back as a re-do bill 18 months later. Ask any resurfacer what prep they do and how many coats.
Why is replacement so expensive when the bath is only $1,000? The bath itself is the cheapest part of the job. The expensive parts are the trade hours (plumber + tiler + waterproofer) and the unavoidable tile damage. Most bath replacement quotes split these out only after the customer has agreed in principle.
Can resurfacing handle the bath plus the surround tiles plus the splashback? Resurfacing covers the bath itself. Surround tiles, splashback tiles, and shower walls are separate scopes; we can also repair tile chips and cracks (/services/tile-repair). For a coordinated finish, we can do bath + tile repair on the same visit.
Can I have the same resurface on a shower base? Yes. The surface repair process for an acrylic, enamel, or stone-composite shower base is the same family of work. See our separate post on shower base repair.
What if the resurface chips a year later? If a resurface fails under normal use, that is a workmanship problem, not wear. Send us a photo. Normal use means no abrasive cleaners, no hot objects placed on the surface, and no removal-related damage.
