5 common signs your bathroom has a shower leak

Ignoring a possible water leak for too long not only wastes water – it can also cause major structural damage to your home and cost you a bucket load in repairs or renos.

But you can avoid all the headaches if you can catch the leak early. And there are many visible signs in your bathroom to help you identify if your shower is leaking! 

How to spot a leaking shower

Sometimes it’s obvious that your shower is leaking and in other cases it could be a ticking time bomb. You might not realise that the peeling paint in your bathroom, the bad odour or damp carpet in the room next door may be a symptom of a leak.

Here are 5 signs to watch out for that indicate you may have a water leak in your bathroom.

Sign 1: Mould and mildew

Over time, it’s relatively normal to see small spots of moulds or a bit of mildew in the grout and tiles of your bathroom. The environment is wet and warm, and this is where mould and mildew thrive. But, if you see this popping up in the walls and ceiling – and it’s not going away, then it’s a clear sign you have a leak. It usually happens because the water droplets from a leaking shower don’t dry and stay in the corners of your bathroom, creating perfect conditions for mould growth.

The first thing you should do is call a professional like the Shower Doctor to assess your bathroom, remove the mould and mildew and fix the leak that’s causing it.

Sign 2: Cracked tiles or gaps in grout

Cracked tiles or broken grout between your shower tiles can also develop over time. This, however, creates an opening for moisture to seep through. If the waterproof layer underneath your tiles and grout are not up to scratch, water will leak through into the walls or underneath your shower. This can promote mould and mildew growth, including rot in your walls and support beams.

You can usually fix this issue by fixing the grout in your shower cubicle. But, if a substantial amount of water has gone through, you may be up for a more costly repair.

Sign 3: Peeling or bubbling paint

Checked the status of your walls lately? It might be telling you something. Bubbling or peeling paint is common in bathrooms with poor ventilation and water damage, especially near the shower. High humidity and moisture found in bathrooms can wreak havoc on your walls and ceilings. Especially if it hasn’t been primed properly or a cheap paint has been used. When the moisture gets in between the wall and paints it destroys the bond between the wall and paint which causes the paint to bubble from the wall and peel.

Rather than paint over the problem area, make sure you properly investigate the root cause, which is likely to be a leak.

Sign 4: Stains

Have you noticed a new stain or discoloured patch in your walls or ceiling? Before your bathroom walls and ceilings show signs of waterlogging and sagging, you’ll often see blemishes first. These dark, brown or copper-like stains are another clear sign of a leak.

If you live in a two-storey house, you may even notice stains in the room below your bathroom. This is when you know you have a severe leakage. We can identify the source of the leak and fix it for you and restore your bathroom.

Sign 5: Bad odour

Think something doesn’t smell quite right in the bathroom? Rotting smells or mustiness is often a sign you have a leaking shower. Unpleasant odours may be the result of stagnant water, where water has accumulated because of a leak. The smell could be even worse if the leak is in your toilet!

An unusually high water bill is also a trigger you may have a leak, but this may not necessarily be isolated to the bathroom.

Repairing a leaking shower

Leaking shower repairs can be extremely costly and time-consuming. If the cause of the leaking shower isn’t properly investigated, the leak might persist and cause more significant damage over time. This may result in a complete rebuild and waterproofing of your shower or the entire bathroom.
