Before you book
What you need to know.
- Retaining fixture positions and changing the layout create different plumbing scopes.
- Select taps, toilets and wastes against the actual connections and finished dimensions.
- Plumbing, waterproofing, tiling and electrical work need coordinated responsibility.
- Confirm access, stages and approval before ordering products or opening surfaces.

Decide what the bathroom project needs to change.
Replacing a worn mixer, renewing a toilet in the same position and moving every fixture involve different work. Begin with the problem you're solving: a repair, a finish update or a new layout. Scott & Sons can discuss the water, waste and fixture plumbing within that project.
The business's association listing includes bathroom renovations, but the plumbing brief still needs to identify exactly what is included. A plumbing quote doesn't automatically cover demolition, waterproofing, tiling, electrical work or complete project management. Clarifying those responsibilities early makes the installation stages easier to coordinate.
Investigate leaks before covering the room again.
Dampness near a shower or vanity may come from a supply connection, waste connection or the surrounding building materials. If the project started because of a leak, have its cause investigated rather than assuming new fixtures or fresh sealant will resolve it.
Existing pipework exposed during a renovation can reveal work that wasn't visible during the first visit. Agree how findings will be explained and approved before walls or floors are closed again. The decision to replace additional pipework should relate to its condition and access, not simply the fact that the room is being renovated.

| Project choice | What needs checking |
|---|---|
| Replace a toilet in position | Waste arrangement, set-out, inlet and floor footprint |
| Replace a vanity or basin | Waste height, supply positions and cabinet access |
| Change shower fittings | Valve compatibility, wall access and finished dimensions |
| Move a fixture | Water and drainage routes, access and buildability |
| Repair a leaking wet area | Source of the leak and coordination with waterproofing work |
Check fixture specifications before ordering.
A toilet has a waste connection and set-out that must suit the installation. A basin waste and mixer need to suit the selected basin and cabinetry. In-wall fittings require particular attention because their concealed components and finished trim need to match before the wall is completed.
Share model numbers, installation drawings and a dimensioned layout. Consider maintenance access as well as appearance, especially for concealed cisterns and fittings behind cabinetry. WELS ratings help compare the water use of regulated products, but a rating doesn't confirm that a fixture fits your room or connections. Resolve those details before delivery.
Coordinate the plumbing stages with other trades.
A renovation can need initial disconnection, work on concealed water and waste lines, then a return to connect fixtures after finishes are ready. The exact visits depend on the project. Provide the builder or coordinator's programme so plumbing isn't booked before access exists or after a required connection has been covered.
Agree how waterproofing, tiling and cabinetry interfaces will be handled. The plumber needs finished positions and relevant product information, while other trades need to know which plumbing must remain accessible. If the only bathroom will be unavailable, plan alternative facilities around the actual stages rather than assuming everything can be completed in a single visit.
Confirm the layout and scope
Define the fixtures, connection work and responsibility for each trade.
Prepare and assess
Arrange access, disconnection and review of any concealed findings.
Complete the required plumbing stages
Coordinate pipework and fixture connections with the approved building programme.
Check and hand over
Review operation, retain product details and record any remaining work.
Allow for strata approvals and shared services.
For a strata bathroom, check requirements with the manager before committing to the works. NSW Government explains that bathroom renovations and changes involving waterproofing need the appropriate approval process. Access, common-property effects and the scheme's by-laws can influence how the project proceeds.
Give the plumber the approved scope, building requirements and authorised contact. Shared shutdowns, working hours and access to another lot may need coordination. A plumbing quote describes physical work; it doesn't determine the scheme's legal approval or responsibility arrangements. Resolve those with the manager or appropriate adviser before the project relies on them.
Compare the complete plumbing quote.
Keeping a fixture in place can reduce changes to the existing route, while relocation can add access and drainage work. Product type, concealed fittings, floor construction and the number of visits also affect the scope. An allowance for installation alone isn't the same as a quote including supply and connection changes.
Ask for the fixtures, stages, removals, testing and exclusions to be identified. Confirm how hidden defects and variations are approved. Keep installed product details, plumbing records and warranty information with the project documents. For a simple running toilet or dripping tap, start with a repair assessment rather than assume a full bathroom refurbishment is necessary.
