How long does a bathroom renovation take in Adelaide?

Same-layout replacement: 3-4 weeks. Reconfigured layout: 5-8 weeks. En-suite conversion or structural changes: 8-12 weeks including council approval. Plan to have an alternative bathroom available for the duration.

Do I need council approval for a bathroom renovation?

Not for a same-layout renovation. You DO need Development Approval if you're adding a new bathroom (en-suite conversion, extension), moving plumbing waste stacks, adding an external window, or making structural changes to the home.

How can I tell if my Adelaide bathroom is properly waterproofed?

You can't easily inspect it once tiled, that's exactly why quotes vary so much. Insist on: (1) two coats of waterproof membrane visible before tiling begins, (2) the licensed waterproofer's Certificate of Compliance issued to the council, (3) 10-year workmanship warranty in writing separate from tile warranties. Watch photos taken between coats being applied.

What's the best tapware for Adelaide hard water?

Chrome finish with ceramic disc cartridges lasts longest in Adelaide hard water. Quality German/Italian brands (Grohe, Hansgrohe, Gessi) outlast budget tapware 3-5x but cost more upfront. For rentals, mid-tier chrome ceramic-disc (Methven, Mizu, Phoenix) offers the best value. Avoid cheap matt black finishes, they scratch and show water spots quickly.

Last reviewed: 28 February 2026 · How we research

A bathroom is the second-highest ROI room in an Adelaide home renovation and by far the highest-risk from a workmanship perspective. Leaks caused by poor waterproofing are the #1 renovation complaint in SA and typically don't appear for 12-24 months, well after the renovator has been paid. This guide covers real all-in pricing by tier, the waterproofing spec that actually lasts, tapware that survives Adelaide hard water, and how to interrogate a bathroom quote line by line.

Real all-in cost by tier

Bathroom pricing spreads wildly in Adelaide. The gap between a $14k and $28k "same size, same fixtures" renovation is almost always in the waterproofing spec, the tile install quality and the tapware brand. Real Adelaide budgets:

Budget same-layout replacement, $12,000-$22,000
Mid-range with frameless screen + floor-to-ceiling tiles, $22,000-$40,000
Premium reconfigured with freestanding bath + custom vanity, $45,000-$65,000
Luxury with structural work + imported finishes, $65,000-$85,000+
En-suite conversion (adding a bathroom), $28,000-$55,000
Waterproofing to Australian Standard AS 3740, $1,800-$3,500 (never negotiate down)

Waterproofing is where bathrooms fail

Australian Standard AS 3740-2021 sets out exactly how bathroom waterproofing must be installed. It requires two coats minimum, specific perimeter heights, waterproof membrane extending under tiles, and licensed waterproofer certification. A properly waterproofed Adelaide bathroom lasts 25+ years. A cheaply waterproofed bathroom leaks into the ceiling below within 12-24 months, always AFTER the workmanship warranty has expired. Never accept the cheapest waterproofing quote. Insist on the licensed waterproofer's name and Certificate of Compliance in your contract.

Tapware for Adelaide hard water

Adelaide hard water is unusually aggressive on tapware. Cheap chrome finishes pit within 6-12 months. Ceramic disc cartridges last 4-6x longer than rubber washers in Adelaide water, insist on ceramic disc. Matt black finishes look great but scratch and show water spots faster than chrome in hard water, factor in ongoing cleaning maintenance. Quality German or Italian tapware (Grohe, Hansgrohe, Gessi) typically outlasts budget Chinese equivalents by 10+ years but costs 3-5x more upfront. For a rental property, chrome ceramic-disc from mid-tier brands (Methven, Mizu, Phoenix) is the sweet spot.

How to shortlist a bathroom renovator

Bathroom renovation has the widest quality spread of any Adelaide trade. The difference between a good and bad bathroom renovator shows up 18 months later, not the day the job finishes.

Ask to see 2-3 bathrooms 18+ months old, new bathrooms all look great, aged ones tell the truth
Verify SA building licence (BLD) and Building Indemnity Insurance (BII) for projects over $20,000
Insist on the licensed waterproofer's name in the contract, not "our team"
Get the tile brand + adhesive brand + waterproof membrane brand all in writing
Confirm the tiler is proper trade-qualified, not a handyman doing a side job
Require Certificate of Compliance for both waterproofing AND electrical work
Get a workmanship warranty in writing separate from product warranties (10 years minimum)

The villain to watch on this job

The leaking shower: The membrane under the shower tiles has failed and water is going into the wall and floor instead of the drain. It is the most common hidden repair in houses built from 1985 to 2010.

How to read a builder's quote

The pro turns straight to the exclusions and the provisional sums. A short exclusions list and few provisional sums means the builder has done the homework on your block. A long list means the price is a starting point and the real number arrives as variations.
