How to Check Your Shower for Leaks and Prevent Costly Repairs
A leaking shower can lead to more than just an annoying drip—it can cause hidden damage, mould growth, and costly repairs if left untreated. Catching leaks early is crucial for preventing extensive damage and maintaining a healthy home environment. Here’s how you can check your shower for leaks and spot early warning signs before they become major issues.
1. Signs Your Shower Might Be Leaking
Shower leaks aren’t always obvious. Some leaks are slow and hidden behind walls or under flooring. Look out for these common signs:
Stale, Damp Smells: If your bathroom has a persistent musty smell, moisture may be trapped in hidden areas, such as behind tiles or under flooring.
Mould and Mildew Growth: Mould thrives in damp environments. If you notice black spots on your walls, ceiling, or around the shower tray, it could be a sign of excess moisture from a leak.
Discoloured or Warped Walls/Flooring: Peeling paint, bubbling wallpaper, or warped flooring near the shower can indicate water damage.
Cracked or Missing Grout and Silicone Seals: Damaged grout or silicone around the shower tray, tiles, or screen can allow water to seep through, leading to leaks over time.
Water Stains on Ceilings Below: If you have an upstairs bathroom, check the ceiling below for damp patches or brown water stains.
2. How to Check for a Leak
If you suspect your shower is leaking, here are some simple checks you can do:
Inspect Seals and Grout: Run your hand along the edges of the shower tray and tiles to check for dampness. If the grout is cracking or missing, water may be seeping through.
Test the Shower Tray: Place tissue or kitchen roll around the base of the shower tray. Run the shower and check if any water escapes onto the paper.
Look for Dripping or Pooling Water: Check under the sink, around the shower pipe connections, and in adjacent rooms for signs of damp patches.
Check the Waste Trap and Pipes: If water is escaping from the waste pipe, it could indicate a loose connection or a crack in the pipework.
3. Preventative Maintenance to Avoid Leaks
Preventative care can help you avoid costly shower repairs in the future. Here’s what you can do:
Re-seal Shower Joints Regularly: Over time, silicone seals degrade. Resealing around the tray and corners every 1-2 years can prevent leaks.
Keep Grout in Good Condition: If you spot cracks in the grout, repair them with fresh grout to maintain a waterproof barrier.
Clean and Maintain the Drain: Hair and soap scum can clog drains, causing water to back up and seep into places it shouldn’t.
Fix Any Issues Promptly: Small leaks can escalate quickly. If you notice any signs of moisture, investigate and repair them as soon as possible.
Final Thoughts
A leaking shower may seem like a minor nuisance, but left unchecked, it can cause structural damage, rot, and expensive repairs. By regularly inspecting your shower for leaks and signs of moisture, you can catch problems early and save yourself from bigger headaches down the line.
