How much does a bathroom renovation cost in Adelaide in 2026?

Most full bathroom renovations in Adelaide cost somewhere between about $9,000 and $32,000 in 2026, going by published local price guides, and premium bathrooms go well past that. Where yours lands comes down to five things: the size of the room, whether the layout changes, the tiles and fixtures you pick, what turns up when the old bathroom comes out, and how much needs rebuilding to meet today's waterproofing rules.

We quote every bathroom individually after we've seen it, so we don't publish a fixed price. People still want a ballpark before they pick up the phone, though, so below are the published numbers and the things that actually move the price on an Adelaide job.

What bathroom renovations cost in Adelaide in 2026

Here are two published ranges. They are third-party figures, not our prices, and they're a starting point for a budget rather than a quote.

Sources: What's The Damage?, Bathroom renovation cost Adelaide (updated October 2026); Three Birds Renovations, How much does a bathroom renovation cost?. Both accessed 5 October 2026.

The Adelaide guide also prices some individual parts of the job: waterproofing at $645 to $3,225, floor and wall tiling at $2,300 to $6,900 and the plumbing rough-in at $1,850 to $4,600. Those line items are a useful reminder that a bathroom is mostly labour and preparation. The vanity and tapware you can see are only part of it.

What a proper bathroom renovation quote should include

When you compare quotes, check that each one covers the whole job. A complete bathroom renovation usually includes:

1. Design and selections: layout, tiles, vanity, tapware and lighting. Our in-house interior designer, Hayley, does this with you before anything is removed.
2. Demolition and rubbish removal, including the old tiles, bath or shower base and screed.
3. Repairs to framing, wall sheeting or the floor once the room is opened up.
4. Plumbing rough-in: water supply and waste pipes to the new positions.
5. Electrical for lights, exhaust fan, heated towel rail and power points, by a licensed electrician.
6. Waterproofing of the shower area, floor and wall junctions.
7. Screeding and tiling of floors and walls.
8. Fit-off: vanity, toilet, tapware, shower screen, mirror and accessories.
9. Final clean and handover.

Ask whether fixtures are priced as exact products or as allowances, who does the electrical work, and whether you'll receive compliance certificates. In South Australia your plumber must give you an electronic certificate of compliance (eCoC) within 7 days for plumbing work such as pipework from the mains or sewer and sanitary drainage, and your electrician within 30 days (SA.GOV.AU).

The five things that move the price most

1. Moving fixtures

Keeping the toilet, shower and basin where they are is the single biggest saving. Moving a toilet or shower means new drainage with the right fall, and in a slab-on-ground home that usually means cutting into the concrete. Timber floors are often easier to work under.

2. Tiles and how much wall you tile

Floor-to-ceiling tiling costs more than part-height. Patterned layouts, mosaics and very large tiles take longer to set out and cut. Picking one feature (a niche, a feature wall or a patterned floor) and keeping the rest simple is a good way to control cost.

3. Fixtures and fittings

Wall-hung vanities, in-wall cisterns, freestanding baths, frameless screens and heated towel rails all add supply and installation time. We can supply everything, help you choose, or fit fixtures you've bought yourself.

4. Waterproofing done properly

This is not the place to save money. Waterproofing is the work you can't see once the tiles go down, and fixing it later means lifting those tiles.

5. What's behind the old tiles

Older bathrooms can hide rotten framing, water damage from a leaking shower, tired galvanised pipes or asbestos sheeting. Nobody can see all of this before demolition, so ask any renovator how they price and approve extra work if they find it, and keep a buffer. Three Birds Renovations suggests setting aside an extra 10 to 20% for surprises.

The rules behind waterproofing in SA

South Australia's building code is still NCC 2022 (Amendment 2), which stays in force until 30 April 2027, when the building part of NCC 2025 takes over (PlanSA). Under NCC 2022, wet-area waterproofing follows Part 10.2 of the ABCB Housing Provisions, or a combination of those provisions and the Australian Standard AS 3740-2021 (ABCB NCC Navigator).

Two rules worth knowing:

• In a shower with a hob, step-down or level threshold, the shower floor must be waterproof and the shower walls waterproof to at least 1800 mm above the floor substrate (Housing Provisions 10.2.2).
• Where a floor waste is installed, the floor must fall to it at between 1:80 and 1:50 (10.2.12), so water drains instead of sitting.

Because we're licensed plumbers (Licence No. 284188), our own team does the waterproofing, drainage and pipework on every bathroom we renovate.

Asbestos in older Adelaide bathrooms

SafeWork SA says a home built or renovated before the mid-1980s is highly likely to contain asbestos products, a home from the mid-1980s to 1990 is likely to, and a home built after 1990 is unlikely to. Inside the house, it lists the bathroom, laundry, kitchen and under floor coverings among the common places to find it (SafeWork SA).

If there's a chance your bathroom walls or floor contain asbestos, get the material tested before demolition. SafeWork SA recommends a licensed asbestos removalist for removal, and friable asbestos must be removed by one. Asbestos waste must never go in household bins or council hard rubbish. If removal is needed, allow for the extra cost and a few extra days.

How long does a bathroom renovation take?

Most of our complete bathroom renovations take around 3 to 4 weeks on site once demolition starts, depending on size, tiling and any custom joinery. Before that there's design, selections and ordering. A standalone shower renovation is shorter. Waterproofing membranes also need their manufacturer's curing time before tiling, which is one reason a good bathroom can't be rushed.

Approvals and insurance

Many bathroom renovations stay inside the existing room, but work that changes structure, adds floor area or affects a heritage-listed property can need approval. Check your address on PlanSA or ask your council. If domestic building work needs council approval and costs $20,000 or more, the builder must take out building indemnity insurance before work starts (SA.GOV.AU). You can check any tradesperson's licence on the CBS licence search.

Ways to keep your bathroom renovation on budget

• Keep the toilet, shower and basin in their current positions where you can.
• Spend on what you use every day (tapware, shower and storage) and save on the rest.
• Make your tile and fixture selections early, so nothing is rushed or substituted.
• Keep a contingency for what's behind the walls.
• If the laundry needs doing too, consider doing both together while the trades are already on site.
