Canberra Bathroom Renovations for Older Homes: What to Expect
Canberra is a city of beautiful older homes. From the garden-suburb cottages of Reid, Ainslie and Braddon to the mid-century brick houses of Yarralumla, Deakin, Griffith, Narrabundah, Curtin, Garran and O'Connor, much of the capital's established housing stock was built between the 1920s and the 1980s. These homes have character, generous blocks and mature gardens, but their bathrooms often tell their age. If you are planning a renovation, it pays to understand what lies behind those original tiles before the first one comes off the wall.
At The Bathroom Co, we have been renovating Canberra bathrooms and laundries for over 30 years, so there is no challenge in an older ACT home we have not faced and solved. Here is an honest guide to what to expect when you renovate a bathroom in an older Canberra home.
Asbestos: the first thing to check, handled by licensed professionals
The single most important consideration in any older Canberra home is asbestos. WorkSafe ACT advises that a residential building constructed or refurbished before 1990 is likely to contain asbestos-containing material. Asbestos was used extensively in Australian building products from the late 1940s until it was phased out by 1990 and banned outright in 2003.
In a bathroom specifically, asbestos can be present in several bonded materials: fibro or asbestos-cement (AC) sheeting used as wall and ceiling linings, older vinyl floor tiles and their backing, tile adhesives and some textured coatings.
These materials are generally safe when intact and undisturbed, the risk arises when they are cut, drilled, sanded or smashed during demolition, which can release fibres into the air. The message here is simple and reassuring: you do not handle this yourself. Under ACT law, a licensed asbestos assessor inspects and tests suspect materials, and a licensed asbestos removalist safely removes anything that contains asbestos before renovation work continues. A good renovator arranges this as part of the project so that any removal is scoped, budgeted and scheduled up front, rather than discovered mid-demolition, which causes delays and unbudgeted cost. A pre-renovation assessment typically costs a few hundred dollars and is one of the most cost-effective steps you can take to protect your budget and timeline.
Why asbestos-awareness is especially high in Canberra: the "Mr Fluffy" context
Canberra has a distinct and painful history with asbestos that explains why awareness here is so high. Between 1968 and 1979, a company known as "Mr Fluffy", Dirk Jansen's D. Jansen & Co. Pty Ltd, which marketed the product as "Asbestosfluf", installed loose-fill (raw, friable) asbestos as ceiling insulation, predominantly brown amosite imported from South Africa, blown into the roof spaces of Canberra homes. This is a different issue from the bonded asbestos-cement materials found in bathrooms, loose-fill was a roof-space insulation product, not a building material used in wet areas.
Importantly, the identified loose-fill homes have already been addressed. In 2014, the ACT Government announced the Loose-fill Asbestos Insulation Eradication Scheme, supported by a $1 billion loan from the Australian Government, to acquire, demolish and safely dispose of affected properties; the first demolitions began in July 2015. A list released by the ACT Government in 2015 confirmed 1,022 affected properties, spread across more than 70 Canberra suburbs. Almost all have now been demolished. According to The Canberra Times, as of 2025 just fourteen privately owned Mr Fluffy houses remain in the ACT, and the government will review its position on the small number of remaining properties in 2027. Known affected properties are recorded on the Affected Residential Premises Register, maintained under the Dangerous Substances Act 2004. In short: if you are buying or renovating, loose-fill status is a known, documented and publicly checkable matter, and it is separate from the everyday bonded-asbestos checks that apply to any pre-1990 bathroom.
Ageing plumbing: galvanised steel and reduced pressure
Many older Canberra homes were plumbed with galvanised steel water pipes, steel coated in zinc to resist rust. Over decades the zinc coating wears away and the pipe corrodes from the inside out. The build-up narrows the internal diameter, which is why so many older bathrooms suffer from low or uneven water pressure, and occasionally discoloured water when a tap is first turned on. Galvanised pipe has a typical service life of several decades, so most surviving runs are now well past their prime.
A renovation is the ideal time to replace ageing galvanised supply lines with modern copper or PEX, restoring pressure and water quality. All plumbing and drainage work in the ACT must be carried out by a licensed plumber, who lodges the required notices and plans with Access Canberra.
Older wiring and bathroom electrical safety
Electrical standards have moved on significantly. Homes wired several decades ago often predate modern requirements, including residual current devices (RCDs, or safety switches) and the bathroom "zone" rules in the AS/NZS 3000 Wiring Rules that govern how close fittings can be to water. A renovation is the right moment to bring the bathroom's wiring up to current standards: adding RCD protection, correctly zoned and IP-rated fittings, and safe, compliant lighting. As with plumbing, all electrical work must be done by a licensed electrician.
Uneven floors, dated layouts and draughty windows
Once the room is stripped back, older homes commonly reveal a few more surprises: Uneven or damaged floors and subfloors.
Timber subfloors may have movement, rot or previous patch repairs, and concrete slabs can be out of level. These need correcting before waterproofing and tiling so the finished floor drains properly and lasts.
Small, dated layouts. Original bathrooms in older Canberra homes are often compact and closed-in. Reconfiguring the layout (or borrowing space from an adjoining area) can transform how the room works, though moving plumbing adds cost and requires approvals.
Single-glazed or draughty windows. Original bathroom windows can be draughty and prone to condensation. Upgrading glazing or improving ventilation makes a real difference to comfort and mould control through Canberra's cold winters.
Heritage considerations in some inner-Canberra suburbs
Several of Canberra's oldest suburbs contain heritage-listed precincts. Reid, for example, is the ACT's largest heritage housing precinct (ACT Heritage Register Entry No. 20023, first listed on the Register of the National Estate on 21 October 1980), and there are listed precincts in Ainslie (Corroboree Park, Wakefield Gardens and Alt Crescent), Braddon, Barton, Forrest and Griffith. Heritage listing is primarily about protecting the external character and streetscape of these areas, so an internal bathroom renovation is usually far less affected than external works. However, if your home is in a heritage precinct, or you plan to alter windows or external elements, additional approval may be required, and it is worth confirming the position early. A renovator experienced with older ACT homes will know how to navigate this.
The process: what to expect, and why local experience matters
Renovating a bathroom in an older Canberra home follows a clear sequence: a pre-renovation inspection and asbestos assessment; a detailed, fixed-price proposal; any required asbestos removal and remediation of plumbing, wiring or floors; then waterproofing, tiling and fit-off, with the required Access Canberra inspections along the way. Because older homes carry more unknowns, it is wise to allow a contingency in both budget and timeline for hidden issues.

Frequently Asked Questions
Do I need an asbestos test before renovating my older Canberra bathroom?
If your home was built or refurbished before 1990, WorkSafe ACT advises it is likely to contain asbestos containing material, so an assessment before work begins is strongly recommended. A licensed assessor tests suspect materials and, if asbestos is found, a licensed removalist handles removal safely as part of the renovation. You should never disturb or handle suspected asbestos yourself.
Is "Mr Fluffy" asbestos the same as the asbestos in my bathroom?
No. "Mr Fluffy" refers to loose-fill (friable) asbestos insulation blown into roof spaces of Canberra homes between 1968 and 1979 — a separate issue that the ACT Government has addressed through its Eradication Scheme. Bathroom asbestos is typically bonded asbestos-cement sheeting, vinyl floor tiles or adhesives, which is managed through standard testing and licensed removal.
Will I need to replace the plumbing and wiring too?
Often, yes, at least in part. Older galvanised steel pipes corrode and reduce water pressure, and older wiring may not meet current bathroom safety-zone and RCD requirements. A renovation is the ideal time to upgrade both, using a licensed plumber and licensed electrician.
Does a bathroom renovation in a heritage suburb need special approval?
Internal bathroom renovations are usually much less affected by heritage listing than external changes, because listing mainly protects streetscape and external character. If you are in a heritage precinct or plan to change windows or external elements, additional approval may be required — confirm this early with your renovator.
How long does renovating an older bathroom take?
It varies with scope and any remediation required. Older homes can add time for asbestos removal or plumbing and floor repairs, which is why building a contingency into the timeline and choosing an experienced local renovator matters.
