C's Plumbing & Gas handles all the rough-in, drainage, and gas work for bathroom renovations across Brisbane's southside — so your builder or tiler has a solid base to work from. QBCC-licensed, fully insured, available 24 hours.
Older suburbs like Holland Park, Mount Gravatt, and Cannon Hill are full of character homes that were never designed with modern bathrooms in mind. Narrow wall cavities, galvanised supply lines that have quietly corroded for decades, and terracotta drainage that shifts with the clay soil — these are the realities we work around every day when we come up to Brisbane for renovation rough-ins.
As bathroom renovation specialists, we focus on what happens inside the walls and under the slab: relocating waste and vent stacks, upgrading supply lines to copper or PEX, setting shower wastes to correct falls, and roughing in for new vanities, baths, and heated towel rails. Getting this stage right is what stops callbacks once tiles are down and fixtures are in.
We travel the M1 corridor from our Yatala base regularly, and we coordinate closely with builders, tilers, and cabinetmakers to make sure inspections happen at the right time and nothing holds up the next trade. If your reno also involves a gas hot water upgrade or a new gas bayonet, we issue the Gas Compliance Certificate on the same job — one crew, less scheduling friction.
Every quote is provided upfront before work begins, and we carry full insurance on every site. If something unexpected turns up once the walls are open — and in Brisbane's older housing stock, it often does — we talk you through the options before touching anything additional.
Relocating floor wastes, repositioning toilet pans, and re-grading drainage to correct falls — essential groundwork in Brisbane's older homes where original terracotta lines can't simply be tapped into.
Replacing corroded galvanised pipework with copper or PEX before tiling begins, improving flow rates and eliminating the discolouration and pressure drop common in southside homes built pre-1980.
Setting shower wastes to the correct fall, roughing in for freestanding baths, and positioning mixer tap outlets accurately so finished tile work lines up with your chosen fixtures.
Final connection of vanities, basins, toilets, and tapware once tiling is complete — timed to suit your build schedule and checked for correct operation before sign-off.
Upgrading to a new electric, gas, solar, or heat pump system as part of the renovation, including all pipework modifications and Gas Compliance Certificates where applicable.
Licensed gas fitting for instantaneous hot water units, heated towel rails, or relocated gas lines — with a Gas Compliance Certificate issued on completion for your records and insurer.
Yes — we regularly travel to Brisbane's southside from our Yatala base, covering Holland Park, Cannon Hill, Mount Gravatt, and surrounding areas. Lead times vary depending on the stage of your renovation, so it's worth reaching out early. For urgent issues during an active reno, we also offer 24-hour emergency call-outs. Call us on 0405 275 741 to check availability.
We provide an upfront quote based on the renovation drawings and a site discussion before work starts. If opening walls or lifting floors reveals unexpected issues — deteriorated terracotta, corroded galvanised lines — we stop, explain exactly what we've found, and give you a revised scope before proceeding. You won't be presented with surprise charges after the fact.
Yes. In Queensland, any work involving drainage, water supply, or gas must be carried out by a QBCC-licensed contractor. Once the rough-in is complete, a plumbing inspection is required before walls are closed. For any gas work — such as a new instantaneous hot water system — we issue a Gas Compliance Certificate, which your insurer and body corporate may require. We manage all of this as part of the job.
