Commercial plumbing built for café fit-outs.
Industry Overview
Every café is different, but every successful fit-out depends on one thing — a hydraulic system that supports efficient operation from opening day.
Oliver & Sons Plumbing works alongside builders, shopfitters and equipment suppliers to deliver commercial plumbing in accordance with the approved hydraulic design and construction program.
Key Differences
Dedicated water supply and drainage for espresso machines, including filtration where required.
Café fit-outs may require grease arrestors and authority approvals depending on the services offered.
Services are installed to approved hydraulic designs while coordinating with cabinetry and equipment.
Plumbing integrates with refrigeration, electrical and other trades throughout construction.
The Build Sequence
01
Review hydraulic drawings, confirm the project scope and coordinate the plumbing works with the builder before construction begins.
02
Install underground drainage, water services and in-wall pipework before wall sheeting and internal finishes.
03
Install fixtures, equipment connections and complete the final plumbing fit-off once finishes are complete.
04
Pressure test the system, complete commissioning and provide the required compliance documentation before handover.
Our Approach
Oliver & Sons Plumbing works alongside commercial builders, shopfitters, project managers and other project stakeholders, coordinating plumbing installations with the wider construction program to support efficient project delivery.
From new cafés through to tenancy refurbishments and fit-out upgrades, we provide dependable plumbing installations that prioritise quality workmanship, clear communication and reliable project delivery.
The Outcome
Whether you're constructing a standalone café, fitting out a tenancy within a shopping centre or refurbishing an existing venue, our objective remains the same — delivering commercial plumbing that supports practical completion and provides the plumbing infrastructure required for day-to-day café operations following project completion.
Industry-Specific Plumbing
Café fit-outs combine a working kitchen with front-of-house service, so the hydraulic rough-in has to land before cabinetry and tiling. These are the plumbing requirements we typically handle on a café fit-out:
Trade Waste & Grease Arrestors
Grease arrestor sizing and installation to meet local water authority trade waste requirements for café fit-outs.
Commercial Sinks & Dishwashers
Stainless steel sink units, dishwasher connections and compliant waste traps for wash-up areas.
Coffee Machine Water Services
Dedicated cold water supply and drainage for espresso machines, including under-counter filtration and water treatment.
Hot Water Systems
Correctly sized hot water units for continuous demand across sinks, dishwashers and equipment.
Drainage & Floor Wastes
Floor wastes, trench drains and in-ground drainage installed to suit café layouts.
Rough-In & Fit-Off
Full hydraulic rough-in ahead of cabinetry and tiling, then final fit-off and commissioning.
Our Shopfit Process
We work alongside builders, shopfitters and other trades to deliver commercial plumbing in line with the construction program. From planning through to project completion, our focus is on quality workmanship, clear communication and completing our plumbing scope efficiently.
Commercial projects rely on careful sequencing. Every plumbing stage needs to align with construction milestones to avoid delays, minimise clashes with other trades and achieve practical completion on schedule. Our process is designed around commercial builders, ensuring every stage is completed efficiently and communicated clearly.
Review hydraulic and architectural drawings, confirm scope and coordinate with the builder before work begins.
Inspect existing services, confirm access, verify dimensions and finalise construction sequencing.
Install underground drainage, water services and in-wall pipework before wall sheeting and finishes.
Coordinate with cabinetmakers, electricians, tilers, kitchen suppliers and other trades throughout construction.
Install fixtures, tapware and equipment connections once cabinetry, finishes and equipment are complete.
Pressure test the system, complete commissioning and provide the required compliance documentation.
Final inspection, certification and project handover ready for practical completion and tenancy opening.
Working With Builders
Commercial fit-outs rely on close coordination between multiple trades. Our role is to complete our plumbing scope in accordance with the approved hydraulic design while working alongside builders, shopfitters and other contractors throughout construction.
We communicate directly with builders, site supervisors and project managers throughout the project, responding to RFIs, confirming plumbing requirements and coordinating our work with other trades.
Key point — A direct line to the site team, not layers of sub-contractors.

Learn MoreCommon Requirements
Kitchen Services
Dedicated cold water supply and drainage for espresso machines, including under-counter filtration and water treatment where required.
Set-downs are confirmed with the equipment supplier during rough-in, ahead of cabinetry and the machine installation.
Key Considerations
Dedicated cold water supply and drainage for espresso machines, including under-counter filtration and water treatment where required.
Set-downs are confirmed with the equipment supplier during rough-in, ahead of cabinetry and the machine installation.
Key Considerations
Wash-up sinks needing dedicated hot and cold supply and robust waste connections.
Set-downs are confirmed with the cabinetmaker during rough-in, before benches and tiling are installed.
Key Considerations
Commercial dishwashers need dedicated hot and cold supply, compliant waste connections and drainage sized for high-temperature, high-volume wash cycles.
Connections are roughed-in ahead of cabinetry and confirmed against the specified equipment, then connected at fit-off where required.
Key Considerations
Stainless benches integrate sinks, taps and waste connections into the joinery, so hydraulic set-downs must line up with the bench layout.
Sink and waste positions are confirmed with the cabinetmaker during rough-in, ahead of bench installation and tiling.
Key Considerations
Drainage points set into the floor to carry wash-down water and spillage to the drainage system, keeping the floor safe and operable during cleaning.
Positions and falls are set during rough-in, before the slab or screed is poured — falls cannot be adjusted once the floor is cast.
Key Considerations
Grease arrestors capture grease and food solids before they enter the sewer and are required by local water authorities for most commercial kitchens.
The arrestor is sized to the fixture load and positioned early, as it affects drainage falls, floor levels and the grease line layout.
Key Considerations
Wastewater discharged from a commercial kitchen into the sewer, regulated by the local water authority. Most kitchens need a trade waste agreement and compliant pre-treatment where applicable.
The grease line, arrestor size and discharge point are confirmed during rough-in so the connection meets authority requirements.
Key Considerations
Carries wastewater from fixtures, equipment and floor wastes to the sewer or trade waste system.
Pipe sizes, falls, junctions and discharge points are set before the slab is poured. Because falls cannot be adjusted once the floor is cast, the layout has to be right at rough-in.
Key Considerations
Hot water systems serve the continuous demand of the fit-out across basins, sinks, equipment and amenities. The system is sized to the fixture and equipment load to avoid undersupply during service.
Selected at design stage, roughed-in with the other hydraulic services, and connected and commissioned during fit-off where required.
Key Considerations
Hot and cold water rough-in and fit-off to fixtures, equipment and amenities across the fit-out.
Set-downs are confirmed during rough-in, ahead of cabinetry and finishes, so taps, basins and equipment connect correctly at fit-off.
Key Considerations
Pressure testing and commissioning confirm the hydraulic system performs as specified. Water services are pressure-tested, drainage flows checked, and fixtures and equipment connections commissioned where required.
Testing and commissioning are scheduled during fit-off so any issues are resolved before final sign-off.
Key Considerations
Depending on the project and local authority requirements, fit-outs may require inspections relating to the plumbing installation. Where an inspection forms part of our plumbing scope, we prepare the relevant plumbing work for inspection at the appropriate stage of construction and complete any required plumbing rectifications before progressing.
Key Considerations
