Bathroom renovation plumbing, Central Coast Bathroom Renovation Plumbing
Licensed plumber & gas fitter · the Central Coast & Lake Macquarie
We handle the plumbing side of a bathroom renovation end to end: drainage set-out and core holes through slab, in-wall cistern and bath rough-ins, laundry and powder-room runs, then back for the fit-off once tiling is done. Accessibility and NDIS bathrooms are part of that work, quoted against the drawings before the room is stripped. We work in with your builder and tiler, and after enough bathrooms together we can also bring trades we already trust.

Recent work
Donza Plumbing is a plumber in Mannering Park, and recent bathroom renovations taken through to fit-off include one there, two bathrooms in Gwandalan, Lake Munmorah, Wyee Point, Yarramalong and Bonnells Bay. A three-room renovation at Bateau Bay has reached fit-off, with a 150 kg concrete freestanding bath in the new bathroom. At The Entrance, we cored holes through a suspended slab so an outdated bathroom could be laid out again. In Woongarrah, we roughed in a laundry and powder room as part of a larger renovation. Photos of the finished rooms are on the bathroom jobs page.

Bathroom Renovation Plumbing FAQs
Do you do the whole renovation or just the plumbing?
The plumbing, end to end. Demolition, tiling and cabinetry belong to their trades; our job is everything water and gas touches, from the first drainage set-out to the final tapware fit-off. We work in with the builder and tiler you already have, and if you are starting from scratch we can point you to crews we have finished bathrooms alongside.
Can you move the toilet, shower or vanity to a new spot?
Usually yes, and it is the most common reason a renovation needs a plumber early. Moving fixtures means new drainage falls and sometimes core-drilling through slab, which we scope and price before demolition starts, so there are no surprises once the floor is open.
When should the plumber get involved in a renovation?
Before demolition. The rough-in has to be planned against the new layout, and quoting it off the finished drawings, not mid-demo, is what keeps the price fixed. We do a site visit, agree the set-out with your builder or tiler, rough in once the room is stripped, and come back for fit-off after tiling.
