Agree the dust controls and household plan before demolition, including containment, worker access, waste movement, cleaning, noisy work and service shutdowns.
Residents should remove personal items and stay outside the controlled work area. No occupied renovation can be promised dust-free.
What should be agreed before work starts?
Walk through the proposed work and access areas with the renovator. Mark the bathroom, worker entry, material storage, waste route and occupied rooms that must remain accessible.
- Personal items: Remove toiletries, towels, medicines, laundry and loose furnishings from the bathroom and nearby route.
- Surface protection: Agree which floors, stairs, doors and fixed finishes need covering before tools and waste move through the home.
- Separation: Confirm how the bathroom and work route will be isolated without blocking exits or creating trip hazards.
- Communication: Nominate one contact for access, deliveries, shutdowns, escaped dust and scope changes.
- Facilities: Confirm which toilet, shower and basin remain usable before any fixture is disconnected.
The QBCC recommends agreeing timelines, milestones and site access upfront. Record later changes and decisions in writing.

How should construction dust be controlled?
Ask which tasks will cut, grind or drill tiles, mortar, concrete or fibre cement. These materials can release respirable crystalline silica, a very fine hazardous dust.
WorkSafe Queensland puts isolation and source controls ahead of relying on respiratory protection alone. The contractor must match the control to the material, tool and task.
Depending on that assessment, controls may include physical separation, on-tool extraction or correctly supplied water suppression. A plastic doorway barrier by itself is not a complete silica control.
Water suppression is also not a universal instruction. The method must control slurry, slips and electrical risks while supplying enough water throughout a suitable task.
Air cleaners or a planned pressure arrangement may support containment, but they do not replace capture at the source. Residents should not design airflow or seal building systems themselves.
How should debris and settled dust be handled?
Agree how waste will be contained before it leaves the bathroom. The route should protect occupied rooms and common areas without spreading loose dust from bags, clothing or footwear.
Dry sweeping and compressed air can put silica-containing dust back into the air. WorkSafe Queensland instead identifies wet cleanup or an appropriate M- or H-class industrial vacuum for silica work.
An M- or H-class unit is an industrial hazardous-dust vacuum, not an ordinary household cleaner. Residents should not enter the work zone to vacuum construction dust themselves.
Set practical inspection points for the barriers, doorway edges, protected floors and waste route. If visible dust escapes, keep residents out while the contractor reviews containment, source control and cleanup.
How can you reduce disruption to the household?
Map deliveries, parking and worker access around the property's actual constraints. Apartments may also need building approval, lift protection, common-area controls and coordination of shared shutdowns.
Ask for advance notice of noisy demolition, cutting and drilling. Children, pets and people affected by noise or dust may need to be away from both the work area and access route.
Plan each water shutdown around the fixtures it affects. Keep the known property isolation point accessible, but do not operate an unidentified or shared control.
If this is the only bathroom, arrange another toilet, shower and handwashing option before disconnection. Do not enter an active work zone to use partly removed fixtures.
The renovation sequence explains when the most disruptive bathroom stages occur. Put the agreed access and cleaning arrangements into the scope when you check the renovator's quote.
When should work stop?
Stop disturbing an unidentified sheet, backing, adhesive, coating or flooring when asbestos cannot be ruled out. Age and appearance alone cannot confirm whether a material contains asbestos.
The Queensland asbestos guidance says to look, check and prepare before renovating. Do not drill, cut, sand, scrape or sample suspected material yourself.
Keep clear if water reaches tools, leads, outlets, fittings or wiring. A barrier also needs revision if it blocks an exit, creates a trip risk or interferes with essential building systems.
Bathroom plumbing and electrical work belong to the appropriately licensed trades. The actual scope determines whether Queensland plumbing work is minor, notifiable or permit work.
