Fit-outs and refurbishments

Commercial plumbing on the Sunshine Coast

We plumb commercial fit-outs and refurbishments across the Sunshine Coast, for offices, shops, cafes and healthcare spaces. We work with builders, designers and project managers from the first hydraulic rough-in to the final compliance paperwork, and all our work meets the relevant AS/NZS standards.

How is commercial plumbing different from home plumbing?

Commercial jobs need more paperwork than home jobs. A fit-out is usually built to a hydraulic engineer's drawings, often needs backflow prevention on the water supply, and has to be certified before the space opens. It's also often done inside a building where other businesses, staff or customers carry on around you.

Types of commercial job

Commercial fit-outs and refurbishments

Offices, shops and cafes: staff kitchens, amenities, cafe sinks and hot water, and the old plumbing taken out or capped on a refurbishment.

What we do on commercial jobs

Hydraulic services, water and gas

Cold water, hot water and gas lines run to the drawings for new fit-outs and for changes to existing tenancies.

Hot water systems and filtration units

Hot water for staff kitchens, amenities and wash-down areas, plus filtered drinking water and chilled, boiling and sparkling water units for staff kitchens.

Bathroom and kitchen fit-outs

Amenities, staff kitchens, cafe kitchens and hand basins, from rough-in through to connecting and testing every fixture.

Backflow prevention

Backflow devices stop water in your building flowing back into the town supply. We fit them.

Compliance certification and documentation

The compliance certificates and records that the certifier and the building owner ask for at handover.

Working in a business that's open

If your business stays open while we work, tell us your trading hours and busy times when you book. We clean up after each job.

Maintenance for commercial sites

We also take on selected maintenance for commercial sites: hot water servicing and fixture repairs. For a property you look after, we can set up a regular maintenance plan so these are booked ahead instead of waiting for something to fail.

How a commercial job runs

  1. Drawings and quote

    Send the hydraulic drawings and the program, and we'll send back a quote.

  2. Plan around the site

    Before work starts, tell us when the water can go off, where we can work and what has to keep running.

  3. Rough-in and fit-off

    Pipes, backflow devices and hot water installed to the drawings, then every fixture and appliance connected and tested.

  4. Certify and hand over

    The compliance certificates and documents go to you, the builder or the building owner.

What commercial plumbing costs

Commercial work is usually priced from the drawings. The main things that set the price are the number of wet areas and fixtures, how far the new work is from the existing water, sewer and gas services, and the type and size of the hot water system.

A backflow device on the incoming supply, mixing valves at basins and showers, or filtration and boiling water units each add parts and time. Refurbishments also depend on how much old plumbing has to be removed or capped, and whether it's safe to reuse.

Work inside a tenancy that's trading takes longer than an empty shell, because the water can only go off at agreed times.

We contracted Blue Bourke Plumbing to do the complete plumbing fit out of a secondary dwelling we’re building. We chose Chris because of his knowledge and attention to detail. From our first discussions we knew Chris was the right choice because he came up with practical solutions to some problems early on. Chris has a thorough working knowledge of plumbing and building codes which has made certification hassle free and his workmanship is meticulous, tidy and first rate.
