Repairs for Showers, Basins and Baths
Showers, basins, baths and floor wastes all feed the same drains, so one small fault can show up in three rooms. We work on the lot, old bathrooms included, and we tell you straight what is worth fixing and what is not.

Old Homes on Steep Blocks
Two eras of bathrooms
Fibro and weatherboard homes from the 1940s to 1960s run their pipe work under the floor rather than in a slab, so many repairs happen from below, which keeps the tiles intact. Later brick-veneer houses from the 1960s to 1980s bury the same pipes in walls and slabs.
Slope and speed
Streets climb granite and phyllite walls either side of the valley, and water off a steep roof or driveway gathers pace on the way down, cutting at the bedding around gullies and floor-waste lines low on the block.
Buried surprises
The late-1950s building boom ran ahead of the sewer network, so some early houses started out with septic tanks, and a decommissioned tank or absorption trench can still surface when a bathroom or laundry gets refitted.

What We Fix and Fit
Six jobs cover most of what a bathroom in this suburb needs, from a weeping shower recess to a full fixture swap during a refresh:
Shower Repairs
Taps, mixers and wastes. We reseal leaking shower recesses, replace worn washers and spindles in the showerhead and taps, swap faulty mixers, and clear the shower waste so water drains the way it should.
Leaking Showers
Traced to the source. A shower leaking through to the floor below gets tracked to its cause, whether that is the membrane, a tap body behind the wall, or a worn, perished flange.
Baths and Basins
Seeps and loose fittings. We repair bath wastes and overflow joints, reseat basins that have worked loose on their brackets, replace cracked spouts and pop-ups, and stop the slow seep that stains the vanity cupboard below.
Floor Wastes
Kept flowing. The floor waste takes shower and basin overflow, so we clear the hair and soap that chokes it, check the grate and trap, and rebed the fitting where water pools.
Mixers and Taps
Cartridges and spouts. We swap dripping mixers out, replace cartridges that make the handle stiff, service bath spouts and showerheads, and match new tapware to the existing pipework so nothing gets rethreaded needlessly.
Fixture Swaps
Old out, new in. A new vanity, pan or showerhead gets fitted onto the supplies and wastes already in place, the old unit comes out, and every joint is pressure tested before the room returns to use.

Problems We See in Bathrooms
Shower Leaking Downstairs
A ceiling stain tells the story. Water showing below means the membrane or a pipe in the wall has failed; we trace it, quote the fix and stop the drip at its source.
Floor Waste Ponding
Water with nowhere to go. A floor waste that holds water lets it creep under the tiles; the culprits are usually hair, soap build-up or a trap sitting proud, and clearing it is quick work.
Mixer Stiff or Dripping
A worn cartridge. A mixer gone stiff or dripping at the spout has a cartridge near the end of its life, and the pressure on hillside mains speeds the wear; the swap takes one visit.
Bath Drain Gurgling
A venting fault or a partial blockage. A gurgling bath drain often means roots at a clay joint down the line; we clear it and confirm the flow before leaving.

Why Bathroom Leaks Need Acting On
Bathroom faults look small and stay expensive, because water escaping a shower recess or a floor waste works quietly into timber frames, sheet flooring and ceilings:
Hidden water travels
A membrane leak does not stay in the bathroom. It follows the fall of the floor and the gaps between sheets, and by the time a stain shows on a ceiling below, the repair is bigger than the leak.
Mould follows the moisture
A shower that never quite dries out feeds mould in wall cavities and under vanities, and a family bathroom out of action while it gets treated is a cost no one budgets for.
Small jobs stay small
A perished flange or a choked floor waste is a one-visit fix today. Left alone, the same fault rots a floor, lifts tiles and turns a repair into a strip-out, so the early call saves the bigger bill.
If the drip is coming from a tap rather than the recess, the tap repairs page covers cartridge and spindle work, and leak detection explains how a hidden leak gets pinned down before tiles get touched.

Bathroom Plumbing Questions Answered
Call (07) 3523 6428Why does my floor waste in The Gap smell after storms?
Usually a dried-out seal. Sewer gas can also push back through the drain where old glazed-clay lines meet at joint after joint, so we check the seal, the line and the venting together.
Who owns the pipes between my bathroom and the street in The Gap?
Urban Utilities owns the street side. The public sewer and water mains are its responsibility, and every pipe on the house side of the connection is yours, so bathroom drains inside your property are yours to maintain.
Can a leaking shower in The Gap be fixed without removing the tiles?
Sometimes, yes. A tap body or a perished flange behind the wall is reachable without lifting anything, but a failed membrane usually needs the floor opened, and we trace and quote before any tile comes up.
What makes bathroom pipe access harder on hillside blocks?
The ground and the era. Rock sits close to the surface on the hill blocks, fibro homes run pipes under the floor, and later brick-veneer hides them in slab, so reachability shapes the quote.
Can you move a shower or vanity in a bathroom refresh?
Often, yes. The new spot needs to reach the supplies and drains already in the floor or wall, and you approve the figure in writing before we begin so the layout can be weighed against the budget.
