How it runs

From the first visit to the fit-off

The plumber is needed before demolition. Quoting the rough-in off the finished drawings, not mid-demolition, is what keeps the price fixed.

  1. Step 1

    Site visit & set-out

    We look at the room against the new layout and agree the fixture positions with your builder or tiler. The price is fixed in writing.

  2. Step 2

    Rough-in

    Once the room is stripped, the drainage and water runs go in, with gas where the job needs it.

  3. Step 3

    Fit-off

    After tiling we come back for the tapware, toilet, bath and vanity, then test it.

  4. Step 4

    Certification

    The work is certified to AS/NZS 3500, with the paperwork your builder or certifier needs.

Good to know

Bathroom renovations in Lake Macquarie: common questions

Which Lake Macquarie suburbs have you done bathroom plumbing in?

Bathroom jobs we have done in Lake Macquarie include Wyee Point, Bonnells Bay and Kahibah, and photos of each are on this page. We take bathroom renovation plumbing across all 82 Lake Macquarie suburbs on our list, from a base in Mannering Park on the southern shore of the lake.

What does the plumbing for a bathroom renovation cost in Lake Macquarie?

Our usual range for the plumbing side of a bathroom renovation is $4,000 to $6,000. It does not include supplying the fixtures and fittings. Bathrooms vary a lot, so your exact price is confirmed in writing before any work starts.

Does it matter whether the bathroom is on a timber floor or a slab?

It changes how the drainage is reached, and we do both. At Wyee Point the floor was opened up and a new floor waste and drainage were set in the open floor. At Kahibah the drainage was renewed under the floor. On a slab, a fixture that moves needs core holes, which we scope and price before demolition starts.

Do you set out accessibility and NDIS bathrooms?

Yes. Accessibility and NDIS bathrooms are part of the work, and they are quoted against the drawings before the room is stripped.

Is there gas work in a bathroom renovation?

Sometimes, for example when a gas hot water unit is moved or replaced as part of the job. NSW Fair Trading contractor licence 498220C covers plumbing, drainage and gas fitting, so the gas is done on the same job with its compliance certificate.
