A shower that runs hot then cold, dribbles instead of sprays, or keeps dripping after it is off is frustrating every single day. A shower that leaks into the wall is worse, because you often do not know until the paint bubbles or the skirting starts to rot.
We repair showers across Auckland: mixers and valves, heads and rails, pressure problems and hidden leaks. We work out whether the fault is in the mixer, the hot water system or the pipework, and fix it without ripping out more tiles than we have to.
Pricing: quotes are free, and every job gets a fixed price before we start, so there are no surprises on the invoice.

Temperature swings and scalding risk
When the shower goes suddenly hot or cold as someone uses water elsewhere, the mixer is not coping with a change in pressure on one side. In older homes with low pressure hot water and mains pressure cold, unbalanced pressures make this worse. The fix might be a new cartridge, a different mixer suited to your system, or balancing the pressures.
Hot water safety also comes from the tempering valve, which limits temperature at bathroom fixtures. Under G12/AS1, new plumbing to showers, basins and baths in most homes must be limited to 50 degrees C, a change made in 2023 to reduce scalding. If your shower runs scalding hot, the tempering valve may have failed or be missing, and we check it.
How It Works
Leaks and low pressure
A shower head that drips is usually a worn mixer cartridge or washer. Water outside the shower can be a failed seal around the screen, cracked grout, a leaking waste, or a leaking pipe or mixer body inside the wall. We use leak detection to narrow it down before opening anything up.
Weak pressure has several causes: a scaled shower head or flow restrictor, a partly closed or failed valve, a low pressure hot water system, old galvanised pipe narrowed by corrosion, or a mixer that is not designed for your pressure. Sometimes a clean fixes it; sometimes the answer is a mains pressure upgrade.
Cost
Head and cartridge replacements are at the lower end. Replacing a mixer in a tiled wall, chasing a hidden leak or repiping costs more, and we give you a price before we start. If the shower is beyond repair, we quote a new shower installation instead.
Showers in Auckland homes
Many Auckland villas and bungalows still run low pressure hot water from a header tank, which limits what a shower can do. Plenty of 1970s and 1980s homes have tiled showers over timber floors, where a small long-term leak can do serious damage underneath. In leaky-building era homes with monolithic cladding, a shower leak into an outside wall is particularly worth catching early.
Why Choose Cheeky's Plumbers for Shower Repairs
Leak found before tiles come off
We test the mixer, waste, seals and pipework to pin down a leak before opening a tiled wall, so only the tiles that have to come off do.
Scald check on every job
We check the tempering valve and delivered temperature against the 50 degrees C limit for bathroom fixtures under G12/AS1.
Thermostatic mixer options
If temperature swings are the problem, we can fit a thermostatic or pressure-balancing mixer that holds temperature when someone flushes a toilet, which suits homes with children or older people.
Matched to your hot water
We choose cartridges and mixers that suit your system, whether that is low pressure from a header tank or mains pressure.

Shower Repairs FAQs
Why does my shower go hot and cold?
Usually the mixer cannot cope with pressure changes when other taps or toilets are used. A new cartridge, a better-suited mixer or a thermostatic mixer often fixes it.
How much does a shower repair cost in Auckland?
Replacing a mixer in a tiled wall or chasing a hidden leak costs more and is priced before we start.
Why is my shower pressure so low?
Common causes are a scaled head, a low pressure hot water system, old corroded pipes or an unsuitable mixer. We test to find which.
How hot should my shower water be?
For new plumbing in most homes, G12/AS1 limits hot water at showers to 50 degrees C. If yours is much hotter, have the tempering valve checked.
Can you replace a shower mixer without removing tiles?
Often yes, if the new mixer suits the existing body or we can use a cover plate. We check before we start.
Is my shower leaking into the wall?
Signs include bubbling paint, swollen skirting, musty smells or stains in the next room. We can test the mixer, pipework and waste to find the source.
