A leaking shower or bath might seem like a small issue, but it can lead to significant problems: water damage, mould, rot, and even structural repairs. Whether you’re in Gravesend, Kent, Essex, or South East London, catching leaks early and knowing when to call a professional plumber is essential.


At GladPro Plumbing Services, we specialise in identifying and resolving all types of bathroom leaks — quickly, safely, and professionally. šŸ’§šŸ”§


šŸ” Common Reasons Why Your Shower and Bath Might Be Leaking


Leaks can occur for many reasons — some visible, others hidden behind walls or under floors. Here’s a comprehensive look at what might be causing water to escape from your shower or bath:


1. šŸ’¦ Worn-Out or Damaged Sealant (Silicone Seals & Grout)


The silicone sealant around your bath or shower tray is designed to keep water from seeping into the surrounding areas. But over time, it can:


  • Crack or shrink due to age or cleaning chemicals

  • Become mouldy and peel away

  • Leave gaps where water can escape


Likewise, cracked or missing grout between wall tiles can allow water to travel behind your shower walls or bath splashback, often unnoticed until stains or mould appear.


šŸ› ļø GladPro Tip: Any discoloured or degraded sealant should be removed and replaced by a professional to ensure a watertight finish.


2. 🚰 Leaking Pipework, Waste Connections or Plumbing Joints


Water supply pipes and waste pipes can leak at connection points behind walls, under floorboards, or below the bath or shower tray. These leaks are often slow and hidden, but they cause major damage over time.


Common culprits include:


  • Loose compression fittings

  • Corroded copper pipes

  • Faulty plastic push-fit joints

  • Poorly installed or leaking waste traps


Warning signs:


  • Water stains on ceilings below the bathroom

  • Warped skirting boards or floors

  • Persistent damp smells

3. šŸ› Cracked or Damaged Bath or Shower Tray


Even high-quality bath tubs and shower trays can develop cracks from movement, poor installation, or accidental impacts. Once cracked, water can leak underneath, soaking subflooring and even joists.


  • Acrylic baths may flex if not properly supported

  • Stone resin or fiberglass trays can chip or crack

  • Hairline fractures often go unnoticed until real damage appears


4. 🚿 Faulty Shower Mixer Valve, Taps, or Shower Head


Leaking taps, shower heads, or mixer valves can waste litres of water and hide more serious internal leaks. Hard water (common in Gravesend, Kent, Essex and South East London) can worsen the issue by creating limescale buildup.


Problems may include:


  • Drips from taps or shower heads

  • Leaks from behind the wall plate or mixer valve

  • Worn washers, cartridges, or valve seals


šŸ’§ Some leaks occur inside the wall, leading to long-term structural damage if not addressed.


5. 🧱 Failure of the Waterproofing Membrane (Tanking System)


Behind your tiled surfaces should be a waterproof layer, often called a tanking membrane. If this layer fails — due to poor installation, age, or movement — water can penetrate the walls and floor behind your tiles.


This can lead to:


  • Mould growth

  • Rotting floor joists or plasterboard

  • Loose or dislodged tiles


Fixing this usually involves removing tiles, reapplying waterproofing, and retiling — something our team at GladPro is fully equipped to handle.


6. 🪠 Blocked Drains and Overflowing Waste Systems


A blocked shower or bath drain can cause pooling and overflow, which may appear to be a leak. Common blockages include:


  • Hair and soap scum buildup

  • Scale from hard water

  • Incorrectly sloped or fitted waste pipes


Symptoms include:


  • Slow draining water

  • Gurgling sounds

  • Unpleasant smells


A thorough drain clean or replacement may be needed.
