ROUGH-IN PLUMBING
The plumber installs waste pipes, vent stacks, hot and cold supply lines through walls and floors before lining. All pipe routes, trap locations and fixture rough-in dimensions are set here; changes after lining are expensive.
Major Build Stages
Inside the details.
Fix stage is the most trade-intensive phase of the build. Plumbing, electrical, data, insulation, plasterboard, joinery and finishes must all be installed in the correct sequence. Poor trade scheduling causes costly rework and is the number one source of build delays.

The plumber installs waste pipes, vent stacks, hot and cold supply lines through walls and floors before lining. All pipe routes, trap locations and fixture rough-in dimensions are set here; changes after lining are expensive.
The electrician runs conduit and cables to all switch, power, light and appliance positions. Cable types, circuit ratings and switchboard allocation are specified in the electrical drawings lodged with the permit.
Cat6 data cables, TV antenna cabling and NBN internal cabling are run to all outlet points. Cable pathways and consolidation point locations should be co-ordinated with the electrician to avoid conflicts.
Licensed gas fitters install gas supply pipes from the meter to all appliance connection points: heaters, cooktops, hot water systems. Pipe sizing is calculated from appliance consumption rates and total run length.
Glasswool or polyester batts are installed in external wall cavities and ceilings per the NatHERS specification. Full fill of cavities (no gaps or compressions) is essential; insulation continuity directly affects energy rating.
Gyprock or equivalent sheets are fixed to wall frames and ceiling joists. Sheet selection (standard, moisture-resistant, fire-rated) depends on location. Screw centres and edge clearances are specified in AS 2589.
All showers, bath surrounds and laundry wet zones must be waterproofed with a compliant membrane before tiling. This is a critical hold point; the building surveyor must inspect before the membrane is covered by tiles.
Door jambs are set and plumbed in openings, then door blanks are hung and fitted. Handle heights, latch alignments and clearances must be correct before cornices and trims are fixed around the reveals.
Kitchen cabinets (base and overhead) are installed by the joiner and levelled to the floor and wall. Cabinet installation sequence interacts with tiling, plumbing and electrical; early co-ordination prevents hold-ups.
Bathroom vanity units and built-in robes are installed. These must be fixed to studs (not plasterboard alone) and positioned accurately to align with tiling and plumbing rough-in locations.
Cornice is fixed at the wall/ceiling junction using a wet plaster set. Architraves are fixed around door openings. Profile consistency and mitred joins are assessed at the pre-plaster inspection.
Skirting boards are fixed to the base of walls on all internal timber flooring and carpeted areas. On tiled areas, skirtings are typically installed after tiling is complete to allow correct height control.
Wall and floor tiles are fixed in bathrooms, ensuites, laundries and kitchen splashbacks. Waterproof membrane must be inspected and approved before tiling begins. Tile layout, grout joint size and lippage tolerances apply.
A sealer coat is applied to plasterboard before the final finish coats. Surface preparation (filling, sanding, and priming) determines the quality of the final painted finish.
A pre-plaster inspection (rough-in check) is mandatory before wall linings are installed. The building surveyor checks rough-in plumbing, electrical, gas and structural connections that will be concealed in the walls.
