When we think about bathroom maintenance, we often focus on visible mould or dripping taps—but what about the health of your grout lines? Over time, even the most durable bathroom tiles can fall victim to dirty, deteriorating grout. And if ignored, that buildup could lead to one of the most frustrating home repair issues: a leaking shower.
More than a cosmetic concern
Grout does more than hold your tiles together—it acts as a water barrier. But because grout is porous by nature, it readily absorbs moisture, soap scum, and grime. As this builds up, it can cause the grout to weaken, crack, or erode entirely. Once that happens, water can start leaking through the gaps and into the walls or floor beneath your bathroom, often going unnoticed until serious damage occurs.
Small signs, big problems
Some early signs of grout issues include:
● Discoloured or stained grout lines
● A musty smell in the bathroom
● Cracked or crumbling areas in the shower
● Loose or hollow-sounding tiles
● Water damage on nearby walls, ceilings, or flooring
These issues may seem minor at first, but they’re often the first clues that your shower is no longer watertight. And once water starts escaping, it can spread quickly—leading to rotting timber, mould outbreaks, and expensive repairs.
The power of a deep clean
Professional tile and grout cleaning doesn’t just improve the look of your bathroom—it targets the root of the problem. High-powered tools and specialised cleaning agents are used to penetrate deep into the grout, removing embedded dirt, mould spores, and bacteria. This kind of treatment can restore your bathroom’s hygiene and highlight areas that may need resealing before a leak starts.
In some cases, simply restoring and resealing the grout can prevent the need for full-scale renovations or waterproofing work—saving homeowners thousands of dollars.
Why it pays to call in the pros
While a DIY scrub may work temporarily, professional cleaners have the tools and knowledge to do the job thoroughly and safely. They’re trained to identify vulnerabilities in grout, tile alignment, and shower seals that the average person may overlook.
Experts like the team at Leaking Showers Sealed provide comprehensive tile and grout cleaning with a leak-prevention mindset. Their service goes beyond basic cleaning, offering an in-depth inspection and recommendations for sealing or repair where needed.

If you’ve noticed your bathroom looking worse for wear, or if you’re trying to prevent the headache of a leaking shower, professional tile and grout cleaning is a smart first step. It’s a simple, cost-effective way to keep your tiles looking great—and your bathroom watertight.
