A successful bathroom renovation begins before demolition. The best results come from a clear brief, a practical layout, suitable products and an agreed sequence for waterproofing, tiling, plumbing, electrical work and installation.
This checklist is for Sydney homeowners, investors and property professionals planning a bathroom renovation or a wider home improvement project. For help discussing a renovation brief, visit the Infinity Alliance Project renovations page.
1. Start with the room and the way it is used
List what works in the current bathroom and what does not. Think about storage, circulation, ventilation, lighting, privacy and cleaning. A family bathroom may need durable storage and a practical shower zone, while an ensuite may prioritise a compact layout and better use of wall space.
Measure the room and note the position of doors, windows, plumbing points and fixed elements. Even a simple measured sketch gives your renovation team a more useful starting point.
2. Set a realistic renovation brief
Decide what the renovation must achieve and what would be nice to have. Your must-have list might include a larger shower, improved storage, accessible access or easier cleaning. The second list might include feature tiles, a wall-hung vanity or upgraded tapware.
A clear brief helps keep design choices connected to the way the room will be used. It also makes it easier to compare options when you are reviewing the scope.
3. Plan the layout before choosing finishes
Layout has a bigger effect on everyday comfort than a single finish. Check the clearances around the toilet, vanity and shower. Consider where the shower screen opens, where towels will hang and whether drawers can open without blocking the room.
Moving plumbing or changing the room footprint may affect the scope, so decide early whether the existing layout is staying or whether you want a more substantial change. The earlier this is understood, the fewer surprises there are later.
4. Confirm waterproofing and substrate preparation
Waterproofing is a critical part of a bathroom renovation. The substrate needs to be suitable, surfaces need to be prepared properly and the waterproofing system needs to be installed in accordance with the applicable requirements and manufacturer instructions.
Ask who is responsible for the waterproofing work, what records will be provided and how penetrations, junctions and wet-area transitions will be handled. Keep the documentation with your renovation records.
5. Choose fixtures for performance and maintenance
Choose the shower, toilet, vanity, basin, tapware and accessories as a coordinated set. Check the dimensions, installation method, warranty information and availability before finalising the design.
Consider maintenance as well as appearance. Easy-to-clean surfaces, accessible isolation points and sensible storage can make the room more useful for years after the renovation is complete.
6. Select tiles and finishes carefully
Tiles set the visual direction, but they also affect slip resistance, cleaning and installation. Review samples in the room’s natural and artificial light. Check that the selected tile is suitable for its intended location and that enough material is allowed for cuts, patterns and future repairs.
Use the same approach for paint, mirrors, shower screens, cabinetry and hardware. A finish schedule reduces confusion when several products look similar.
7. Coordinate the trade sequence
Bathroom work often involves several stages and trades. A typical sequence may include protection and preparation, demolition, rough-in work, substrate preparation, waterproofing, tiling, painting, cabinetry, fixtures, electrical finishing and final checks.
The exact order depends on the project. The important point is to agree the sequence before work starts, including who is responsible for measuring, supplying and installing each item.
8. Confirm approvals, access and building requirements
Ask what approvals, notices or building requirements apply to your property. Apartments, strata buildings and managed properties may have rules about working hours, noise, lifts, rubbish removal and access. Confirm these details before booking the work.
For a house, also consider how the household will manage without the bathroom, where materials will be stored and how the work area will be kept safe and clean.
9. Allow time for decisions and supply
Renovations can be delayed when a product is unavailable or a decision is left until the installer is on site. Confirm the lead time for key fixtures, cabinetry, tiles and glass. Keep a written record of the selected products and approved alternatives.
When the scope changes, document the change and its effect on timing before the work proceeds. This keeps the client and renovation team working from the same information.
10. Plan the handover
At completion, check the finishes, fixtures, silicone lines, doors, drawers, ventilation and visible services. Note any outstanding item and agree how it will be resolved. Ask for care instructions, warranties and relevant completion records.
