Did you know that even the smallest leak in your shower might seem harmless? But when winter arrives, even the smallest leak can become a major issue. Cold weather slows evaporation, worsens moisture buildup, and increases the risk of hidden water damage in your bathroom.
We’ve seen it all, from minor cracks that turned into complete shower rebuilds to long-term mould problems that affected a family’s health. And after 28 years in the business, we know one truth better than most:
The cost of ignoring a leak is always higher than the cost of fixing it early.
Why Winter Makes Shower Leaks Worse
Winter conditions in NSW and QLD don’t bring snow, but they do bring heavy rains, colder temperatures, and higher humidity. All of which create the perfect storm for plumbing problems.
- Moisture lingers longer in cool air and enclosed bathrooms, giving leaks more time to spread.
- Hot showers on cold tiles cause expansion and contraction in grout and silicone, increasing the chance of cracks.
- DIY patches often fail in winter because standard silicone doesn’t cure properly in humid or cool conditions.
It’s no coincidence that we see a spike in emergency repair calls during the winter school holidays, when families are home more often, and when the damage is already done.
The Real Costs of a Leaking Shower
Let’s break it down. A leaking shower isn’t just a plumbing issue. It’s a financial risk. Here’s how ignoring it can hit your wallet:
1. Water Waste: Up to $150–$300/year
A single leaking tap can waste up to 24,000 litres of water annually, which is enough to fill over 120 bathtubs. In states where water prices are rising, that can mean $150–$300 per year in wasted water alone.
2. Mould Removal: $500–$3,000+
Prolonged dampness leads to black mould behind tiles, walls, or flooring. Mould isn’t just unsightly. It can also cause respiratory problems, especially in children or older adults.
Professional mould removal in Australia ranges from:
- $500+ for surface mould
- $1,500–$3,000+ for deeper or structural mould remediation
3. Structural Repairs: $2,000–$15,000+
Water seeping behind walls or under tiles can damage plasterboard, timber frames, insulation, and even adjoining rooms.
In many cases we’ve seen at TSRC, the original leak could’ve been fixed for a few hundred dollars, but was left too long and resulted in:
- Rotten subfloors
- Collapsed ceilings
- Full bathroom renovations
4. Insurance Issues: Potential Claim Denial
Many home insurance policies won’t cover water damage if it’s found to be caused by poor maintenance or negligence. A small, ignored leak today could void your coverage when you need it most.
Insurance stats to know:
- 46% of water damage claims in Australia are due to burst or blocked pipes
- 13.4% of claims are linked to overflowing showers, baths, or sinks
The Smarter Move: Early Shower Leak Repair
We get it, life gets busy. But those little signs, like water pooling near your shower or a faint musty smell that just won’t go away, could be warning you of something bigger. And when winter hits, even small leaks can turn into costly, stressful repairs.
That’s why we always say: that the smartest move you can make is to get it checked early.
