It’s the first question almost every homeowner asks the moment they notice a leaking shower: “Do I really have to rip the whole thing out, or is there an easier fix?”

It’s a completely fair question and the honest answer is: it depends on what’s actually happening underneath. Tiles can still look fine, grout might only show a few hairline cracks, and nothing on the surface looks dramatic. But leaks almost never start on the surface. They start with what’s going on beneath the tiles, in the waterproofing membrane and screed most homeowners never see.

This guide breaks down, in plain terms, when a shower leak can be resolved without a full rip-up, when a partial repair is the smarter option, and when a complete rebuild is genuinely the only fix that will last.

Why showers start leaking in the first place

A leaking shower can come from a few different places, and the cause determines the fix:

  • cracked grout or missing silicone

  • movement in the floor creating gaps under tiles

  • hollow (drummy) tiles where adhesive has failed

  • poor falls, meaning water pools instead of draining

  • waterproofing breaking down after years of use

  • water sneaking under the shower screen frame

  • moisture trapped under tiles from previous “quick fixes”

A proper shower repair always starts with identifying why the leak happened, not just what you can see.

Is a shower seal enough? Sometimes — but not always

Many homeowners start by Googling “shower seal” or “fix leaking shower without removing tiles”, hoping for a cheaper or quicker option. A seal can be a valid and long-lasting solution, as long as:

  • there are no signs of waterproofing failure

  • tiles are still firmly bonded

  • there are no hollow or drummy areas

  • moisture readings are low

  • damage is limited to grout or small gaps

In these cases, an epoxy shower seal can work extremely well. Epoxy is stronger, more waterproof, and far more durable than cement-based grout, and it’s the best chance of holding off future leaks if you want a non-invasive option.

But — and this is important to be honest about — if there are signs that the waterproofing is compromised or moisture is already sitting under the tiles, any shower seal is only a short-term solution. It will eventually fail, and you will end up paying for a retile later.

We tell homeowners up front so they can choose knowingly. It’s a bit of a gamble, and you’re welcome to take it, but we won’t pretend sealing fixes everything.

Epoxy seal: from around $1,000

Floor-only repairs: when you DON’T need to retile the whole shower

A lot of people assume a leaking shower automatically means a full rip-up. Not true.

If the leak is isolated to the floor, a floor-first-row retile is usually the most cost-effective and reliable fix. It involves:

  • removing the shower floor tiles

  • removing the first row of wall tiles

  • repairing or replacing the screed as needed

  • rebuilding the waterproofing so it ties properly into the walls

  • retiling the floor and first row

  • finishing with epoxy grout for durability

This repair solves most leaking shower issues while keeping the existing wall tiles.

Why more repair companies don’t offer it

Because it’s technically harder.
You have to blend new waterproofing into old, re-level the floor, prepare the wall junctions correctly, and work around shower screen refitting.

Bigger bathroom companies almost always tell you to rip up the whole shower or the whole room because it’s easier for them, not necessarily better for you.

The catch

Your new floor tiles won’t match the old wall tiles, unless you still have spares. Most homeowners don’t mind — a clean white floor-first-row looks modern and fresh.

Base retiles: starting from $5,000 depending on size and screen type

When you do need a full shower rip-up

A complete shower retile is only recommended when it’s genuinely necessary. This includes:

  • severe waterproofing failure

  • rotten or soft subfloor

  • cracked tiles across multiple areas

  • water leaking to a lower level ceiling

  • major movement in the floor

  • a plumber cutting into walls and damaging waterproofing

  • tiles are discontinued and no match exists, and you want a consistent look

  • your shower is old and you’d prefer everything to match

Sometimes it’s aesthetic, sometimes it’s structural.

Full showers: from around $7,000 depending on layout and walls

Shower screen removal

Whatever repair you choose, the shower screen has to come off to do the job properly. Water loves to sneak under frames and into the hob. Most leaks worsen under the parts you can’t see.

We remove and refit screens for $375–$625, depending on the type of screen.

Why pricing varies and how ‘cheap’ can impact your shower repair

At Allspex Tiling, our pricing is based on:

  • shower size

  • number of walls

  • complexity of the shower screen

  • hours required for the repair

  • waterproofing stages

  • screeding

  • tile removal and prep

  • epoxy grout (harder to apply but lasts years longer)

  • QBCC-licensed tilers doing the work start to finish

Yes, some sole traders will charge less.
But if someone is much cheaper, start asking:

  • Are they using epoxy or cheaper cement grout?

  • Are they doing two coats of waterproofing to avoid pinholes in the membrane?

  • Are they extending waterproofing 150mm up the walls?

  • Do they hold the actual tiling licence, or is it someone else?

  • Who is actually doing the work and do they have the tiling trade qualification?

  • How long is their warranty?
    (Most companies give 6 years because that’s covered by QBCC Home Warranty Insurance. Make sure you’re not being offered the minimum.)

If the repair is priced too cheaply, they have to cut steps to make it worth their while financially.

And your bathroom always pays the price for that later.

How to avoid being ripped off when getting a shower repair quote

Use this checklist:

  1. Ask if they use a moisture meter
    If they don’t check for moisture under the tiles, the diagnosis is guesswork.

  2. If they recommend a floor-only repair, ask how they’ll tie in the waterproofing to the wall
    It must extend to at least the first row.

  3. Ask for two coats of membrane
    If prep isn’t spot on, one coat can sometimes get pinholes. Two coats is what we use – it;s above standard, but that’s why the longer warranty can be offered.

  4. Check their licence
    And make sure the person doing the work actually holds it.

  5. Ask if they use epoxy grout
    It’s more expensive and harder to use, but it lasts. If they’re not using epoxy, their price should reflect that.

  6. Ask about warranty
    If it’s only 6 years, it’s because that’s the minimum they have to offer. And get confirmation in writing they WILL come back for warranty calls and not just disappear.

You don’t always need a full rip-up…but you DO need to know the right repair for you

Not every leaking shower means a major renovation.
Sometimes an epoxy seal is enough.
Sometimes a floor-first-row retile is the perfect middle-ground solution.
And sometimes a full shower retile is the only way to protect your home from long-term damage.

Our job is to diagnose the leak properly and recommend the right fix, not the most expensive one. If you’re unsure which option suits your shower, we’re happy to take a look and give you honest direction.

How to Know Which Option Is Right for Your Shower

The honest answer only comes from an on-site inspection ideally including a degrout or partial tile removal to check moisture levels, voids, and the condition of the substrate underneath. Guessing from the surface alone is exactly how homeowners end up paying twice: once for a reseal that was never going to hold, and again for the retile that follows it.

This is also why the choice of who does the assessment matters. Surface sealing can mask a leak temporarily, but it can’t replace correct waterproofing and getting that distinction right requires a qualified wet-area tiling specialist who understands substrates, membranes, screeds, and drainage, not just tile finishing. If you’re still working out what’s actually causing your leak in the first place, our guide to understanding shower leaks is a useful starting point, alongside our breakdown of the three ways to fix leaking shower tiles.

The Allspex Tiling Approach

At Allspex Tiling, every repair we recommend is backed by warranty, built to Australian Standards, and carried out using materials suited to Queensland’s wet-area conditions. We won’t push a full retile when a floor-first-row repair will genuinely do the job, and we won’t recommend a reseal if we can see it’s only buying you a few extra months.
