Yes. A licensed plumber can diagnose and fix a shower leak when it comes from the taps, mixer, shower outlet, supply pipes, waste or drain connections. If water is escaping through the screen, seals, tiles or waterproofing membrane, waterproofing or tiling work may also be needed. Repair difficulty and timing depend on whether the fault is accessible or concealed and whether damaged finishes need reinstatement.
What a plumber can repair
A plumber can inspect and test accessible fittings, supply lines and waste connections. Because water can travel along pipes, framing and finishes, the visible wet area may not reveal the source. A concealed fault may require a plumber to trace a hidden water leak before recommending access or repair.
Common plumbing repairs include:
- replacing worn tap washers, seals or mixer cartridges
- repairing leaking shower outlets or pipe connections
- repairing or replacing failed supply or waste pipes
- fixing faulty waste and drain connections.
A drip from the shower head when the controls are off often indicates a tap or mixer fault. Moisture appearing when the shower has not been used may indicate a supply pipe or valve leak. Water appearing only during use may come from plumbing, drainage or the enclosure. These patterns are clues rather than proof.
If the plumbing and drainage are sound, the problem may be failed sealant, screen joints, tiles or waterproofing. A plumber can help identify this distinction, but another appropriately qualified trade may need to complete the repair. Applying silicone without confirming when shower sealant can fix a leak will not repair a concealed pipe, faulty waste connection or failed membrane.
What affects difficulty, timing and price?
An accessible tap washer, mixer cartridge or shower outlet connection is relatively quick and straightforward to resolve, whereas a concealed in-wall pipe leak, damaged waste collar or breached waterproofing membrane beneath the tiles requires deeper diagnostic investigation. We do not hide behind vague online price estimates or speculative phone quotes because two shower leaks that show identical damp patches can stem from completely different causes underneath. For instance, a leaking breech piece involves national plumbing standard AS/NZS 3500 pipework regulations, whereas failed sub-tile flashing falls under AS 3740 (the Australian standard for domestic wet area waterproofing, which sets strict rules for membrane continuity and vertical perimeter turn-ups). Assessing your bathroom on site lets our licensed plumber pinpoint the exact fault and walk you through an upfront task breakdown detailing every step of the repair with transparent, fixed pricing and a $0 call-out fee on approved work.
What to do before assessment
Stop using the shower if water is entering a wall, ceiling or adjoining room. Check when a leaking shower is unsafe to use rather than repeatedly testing it.
- Note when and where the moisture appears, and take photos without repeatedly running the shower.
- For an uncontrolled leak, use the property’s main water shut-off valve only if you know where it is and can reach it safely.
- Do not remove tiles, open walls or attempt concealed plumbing, drainage or waterproofing work.
- If water is near lights, power points or electrical fittings, keep clear and do not touch the water, switches or fittings. Seek urgent professional help. Stay away from a sagging or bulging ceiling.
If the source is concealed, unclear or causing active damage, stop using the shower and reach out to our leaking shower repair team for consultative guidance. During your booking call, our team asks a few pre-dispatch screening questions about your home's construction—such as whether you have timber-framed or double-brick walls and if damp is appearing on adjoining floorboards—so our van arrives stocked with precision moisture detectors, acoustic listening gear, and replacement fittings.
