Leaking showers are one of those home maintenance issues that seem small at first but can quickly spiral into a costly headache if ignored.

Yet, despite how common leaking showers are, there are plenty of misconceptions about what causes them and how to fix them. Unfortunately, believing these myths often leads to bigger problems down the track.

So, let’s set the record straight. Here are some top misconceptions about leaking showers—and what you should do instead to solve them.

Myth 1: A Leaking Shower Always Means a Plumbing Issue

One of the biggest misconceptions is that a leaking shower is caused by faulty pipes or plumbing. While leaks can sometimes be due to a burst pipe behind the wall, in most cases, the problem is actually with the shower seal, grout, or waterproofing.

Over time, grout deteriorates, tile seals wear out, and waterproofing fails, allowing water to seep through gaps and cracks.

Instead of immediately calling a plumber, it’s worth getting a specialist in leaking shower repairs to assess the real cause of the problem.

Myth 2: Any Grout or Sealant Will Fix a Leak

It’s tempting to grab a random tube of sealant or slap on more grout to “patch up” a leak. While this might work temporarily, it won’t provide lasting protection unless regrouting is done professionally with the right materials and technique.

Standard grout and sealant from a hardware store aren’t designed for long-term waterproofing. If water has already started seeping behind tiles or into structural areas, simply covering the surface won’t stop the leak at its source.

What You Should Do Instead

Rather than using off-the-shelf products, professionals like Megasealed use specialised, long-lasting sealants and high-quality epoxy grout that is far more durable and water-resistant than standard cement-based grout. This ensures a long-term solution rather than a temporary cover-up.

Myth 3: If There’s No Water, There’s No Leak

Many homeowners assume that if they don’t see water pooling outside the shower, there isn’t a leak. Unfortunately, not all leaks make themselves obvious. Water can seep behind tiles, into walls, or under flooring, causing hidden damage that isn’t immediately obvious.

What You Should Do Instead:

Look for less obvious signs of a leaking shower, such as:

• Mould or mildew growth around the shower or bathroom walls
• Bubbling or peeling paint near the shower area
• Musty smells, even after cleaning
• Loose or cracked tiles

If you notice any of these signs, get a professional leak inspection before the problem worsens.

Myth 4: All Shower Leaks Require Tile Removal

Many people delay getting their shower repaired because they assume it will involve ripping out tiles and a costly renovation. While that might have been true in the past, modern solutions allow for non-invasive leak repairs that don’t require tile removal.

At Megasealed, we specialise in non-invasive tile-over-tile repair solutions. Our exclusive sealing technology ensures long-term protection, giving you a watertight shower without the mess or expense of a renovation.

Myth 5: Any Waterproofing Will Do

Not all waterproofing solutions are created equal. Some cheap DIY waterproofing products wear out quickly, leaving your shower vulnerable to leaks again within a short time.

Always opt for professional-grade waterproofing that is designed to withstand daily use and has a guaranteed warranty. If your shower is showing signs of wear, a professional regrouting and resealing service can reinforce its waterproof barrier, keeping your wet areas leak-free for years to come.
