Apartment Bathroom Renovations Brisbane: Costs, Body Corporate Rules & Ideas

Apartment bathroom renovations in Brisbane are a different job from renovating a bathroom in a house. The room is usually smaller, the building is shared, and between body corporate approval, waterproofing obligations and access logistics, the projects that go wrong usually go wrong before a single tile is lifted.

We renovate apartment and unit bathrooms across Brisbane, from older walk-up blocks to modern high-rise units. This guide covers what apartment owners actually need to know: the real costs, the approval process, and the design moves that make a small footprint feel premium.

How Much Does an Apartment Bathroom Renovation Cost in Brisbane?

Apartment bathrooms are typically 3 to 6 square metres, so material quantities are lower than a house bathroom, but access and compliance add back some cost.

• Essential refresh: $18,000 to $24,000. New vanity, tapware, shower screen, paint and a partial retile. No layout changes, waterproofing stays.
• Complete renovation: $23,500 to $45,000. Complete strip-out, new waterproofing, floor-to-ceiling tiling, new fixtures throughout. Compact apartment bathrooms typically land at the lower end of this range.
• Luxury renovation: $45,000+. Stone surfaces, custom vanity, concealed cisterns, feature lighting and high-end fittings.

Two apartment-specific factors push costs around:

1. Access. Materials in, demolition waste out, through lifts, lobbies and car parks. Higher floors and buildings with strict access hours add labour time.
2. Building age. Pre-1990s blocks often have galvanised pipework or asbestos sheeting that must be handled properly. Budget a 10 to 15 percent contingency in older buildings.

Do You Need Body Corporate Approval? (Usually, Yes)

In Queensland, most apartment bathroom renovations count as an improvement to the lot under the Body Corporate and Community Management Act, and anything touching waterproofing membranes, plumbing risers or common property almost always needs written approval before work starts.

Here is the process we walk owners through:

1. Check your by-laws. Every scheme is different. Some only require notification for like-for-like work; most require a formal application for anything involving waterproofing or plumbing.
2. Prepare the application. Committees typically want the scope of works, your builder’s QBCC licence details, insurance certificates, and details of waterproofing compliance. We supply this pack as part of the job.
3. Allow 2 to 6 weeks. Committees meet on their own schedule. Submit before you order materials, and the approval usually lands by the time your tiles do.
4. Noise and access rules. Most buildings restrict noisy work to weekday business hours and require lift protection. Your builder should manage this with the building manager, not leave it to you.

Skipping this step is the single most expensive mistake in apartment renovating. If an unapproved renovation leaks into the unit below, you are personally liable, and insurance can decline the claim.

Waterproofing: Why It Matters More in Apartments

In a house, a failed membrane ruins your own floor. In an apartment, it ruins your neighbour’s ceiling. Queensland requires waterproofing to AS 3740 installed by a licensed applicator, and in apartments we treat it as the core of the job:

• Full membrane replacement on every strip-out, never patching over the old one
• Flood testing before tiling
• Certificates supplied for the body corporate’s records and your own

If a quote seems suspiciously cheap, waterproofing is usually where the money was saved. It is also the one place it must never be.

Design Ideas That Make Apartment Bathrooms Feel Bigger

Most Brisbane apartment bathrooms have no window and limited floor area. The right choices transform them:

• Wall-hung vanity and toilet. Visible floor equals perceived space, and concealed cisterns buy back 200mm of room depth.
• Walk-in shower instead of a bathtub. Unless you need a bath for resale in a family-oriented building, the shower conversion is the biggest space win available.
• Large-format, light tiles with matching grout. Fewer grout lines read as more space. Running the same floor tile up the shower wall adds height.
• Mirrored cabinets. Storage plus light amplification in one move, essential in windowless rooms.
• Ventilation done properly. No window means the exhaust must actually duct out of the building, not into the ceiling cavity. We check this on every apartment job; a surprising number are wrong.
• Layered lighting. Warm LED strips under the vanity plus good task lighting at the mirror stop the “office bathroom” effect.

How Long Does an Apartment Bathroom Renovation Take?

On site, 2 to 3 weeks for a full renovation. Add body corporate approval time up front, so a realistic start-to-finish window is 6 to 10 weeks from first quote. Buildings with restricted work hours run slightly longer than houses; good scheduling absorbs most of it.

Frequently Asked Questions

Can I renovate my apartment bathroom myself?

In Queensland, any building work over $3,300 requires a QBCC licence, and waterproofing requires a licensed applicator regardless of value. In a strata building, your body corporate will also require evidence of licensing and insurance. Realistically, apartment bathrooms are not DIY territory.

Can I move the toilet or shower in an apartment?

Sometimes. Fixtures connect to shared stacks and risers, so relocation depends on where they run and what the slab allows. We assess this during the quote; keeping fixtures in place is usually the better-value call.

Does a renovated bathroom add value to an apartment?

Yes, and disproportionately so. The bathroom and kitchen carry most of an apartment’s presentation value, and a dated bathroom is one of the most common reasons Brisbane units sit on the market.

Who fixes it if my renovation leaks into the unit below?

If the work was done by a licensed builder with compliant waterproofing, the builder’s warranty and QBCC insurance respond. This is exactly why body corporates demand licensed work.
