Call Now — We'll Sort It 0800 322 322A bathroom renovation is only as good as the plumbing behind it. Tilers and builders do their part, but the pipes, drainage, and gas work need to be right before a single tile goes up. That's where we come in.
Water & Gas Worx handles the full plumbing scope on bathroom renovations across Auckland — from stripping out old pipework to final fit-off. We work alongside your builder, tiler, or project manager to keep the job moving. No delays from our end.
This is the behind-the-wall work that has to be done before lining and tiling. We install all hot and cold water pipes, waste lines, and vent pipes to the correct positions for your new layout. If you're changing where the shower, bath, toilet, or vanity sits, the rough-in is where that happens.
Moving a shower from one wall to another? Adding a second basin? We relocate hot and cold supply lines to match your new bathroom design. We work in copper, PEX, and composite — whatever suits the build.
Getting drainage right is critical. Wrong falls mean slow drains. Wrong venting means gurgling and smell. We install and relocate waste lines for showers, baths, basins, and toilets — all to code, all inspected.
If your bathroom reno involves a gas califont, gas central heating, or underfloor heating with a gas boiler, we handle the gas pipework and certification. Certified gasfitter on every job.
We've done enough bathroom renovations to know the drill. We show up when we're needed, do our stage, and get out of the way so the next trade can start. No chasing us up, no holding up the programme.
Typical sequence: strip-out and demo (builder), rough-in plumbing (us), electrical, lining and waterproofing (builder/waterproofer), tiling, then final fit-off (us again — taps, toilet, shower, vanity connections).
We coordinate directly with your builder or project manager. If you're managing it yourself, we'll walk you through the process so you know exactly what to expect and when.
Walk-in showers, shower-over-bath, wet rooms — we plumb them all. We install concealed and exposed shower mixers, set shower wastes to the correct fall, and make sure water pressure is right. If you're upgrading from an old shower with separate hot and cold taps to a modern thermostatic mixer, we handle the full changeover.
Freestanding baths, built-in baths, spa baths — each one has different plumbing requirements. Freestanding baths often need floor-mounted or wall-mounted taps with specific pipe positions. Spa baths need electrical as well as plumbing connections. We get it right first time so your tiler and builder aren't chasing us for adjustments.
Moving a toilet is one of the trickier parts of a bathroom reno. The waste pipe needs the right fall to the main drain, and there's often a floor joist or concrete slab in the way. We assess whether it's feasible, work out the best route, and install a new waste connection that drains properly and meets code.
Single vanity, double vanity, wall-hung vanity — the plumbing is different for each. Wall-hung vanities need in-wall waste and supply, which means getting pipe positions exact during rough-in. We work from your vanity specs to make sure everything lines up.
Hydronic underfloor heating in bathrooms is increasingly popular, especially in Auckland's older homes. We connect the manifold and loop pipework to your boiler or heat pump system. If gas is involved, we handle the gas certification too.
Good ventilation prevents mould and moisture damage — especially in windowless bathrooms. We install extraction ducting and connect to rangehood-style bathroom fans. If your renovation involves a new ceiling layout, we coordinate vent positions with your builder.
Rough-in is usually 1-2 days. Fit-off (connecting everything after tiling) is typically half a day to a full day. Total plumbing time depends on the scope — a straightforward reno with no layout changes is quicker than a full gut-and-relocate.
Usually yes, but it depends on the floor structure and where the main drain runs. We assess this during the site visit and let you know what's involved. In some cases a macerator pump is needed, but most of the time we can gravity-drain to the existing stack.
If your hot water is gas-fired (califont or gas cylinder) and the reno involves moving or upgrading the unit, yes. We're certified plumbers and gasfitters, so we cover both in one visit.
Absolutely. We coordinate directly with your builder, project manager, or whoever is running the job. We know the sequence and we show up on time.
It depends on the scope. A like-for-like refit (same layout, new fixtures) costs less than a full relocation. We give you a clear price after the site visit — no surprises, no hidden extras.
