Commercial Fit-Out Plumbing: Planning Bathrooms, Kitchens and Services

Commercial fit-outs often have tight construction programs and multiple trades working at once. Plumbing needs to be integrated into the tenancy design early so bathrooms, kitchens, hot water and drainage can be installed without delaying the fit-out.

For more detail on the service itself, see our commercial fit-out plumbing page.

Confirm the tenancy requirements

An office, retail store, restaurant and warehouse can have very different plumbing needs. Start with the final use of the space and the required fixtures.

Check existing services

Before finalising the layout, confirm where existing water, sewer, drainage and hot water services are located and whether they can support the proposed fit-out.

Plan bathrooms and amenities

Toilets, basins and accessible facilities need accurate set-out and coordination with partitions, waterproofing and finishes.

Commercial kitchens need detailed planning

Sinks, dishwashers, equipment connections, hot water and waste points should be coordinated with the final equipment schedule and cabinetry.

Allow for maintenance access

Valves, traps, hot water units and other serviceable components should not be hidden behind fixed joinery without access.

Coordinate rough-in and fit-off

Commercial fit-outs move quickly. Product information and approved plans should be available before rough-in so fit-off is not delayed by incompatible fixtures.

Plan around business opening dates

A clear plumbing scope and realistic sequencing reduce the chance that last-minute plumbing work holds up commissioning or opening.
