The Complete Guide to Bathroom Leaks: Causes, Solutions, and Prevention

Bathroom leaks are one of the most common and disruptive issues homeowners face. What may begin as a minor drip under the sink or a faint water stain on the ceiling can quickly escalate into extensive damage if not addressed properly. Beyond the immediate inconvenience, leaks contribute to wasted water, higher utility bills, and the potential for mould growth, which poses health risks to your family.


At Aquatek, with over 35 years of experience in plumbing, heating, and renovation services, we understand how worrying bathroom leaks can be. Our team has helped countless homeowners in London, Essex, and Hertfordshire fix hidden leaks, prevent future water damage, and restore peace of mind. In this article, we’ll walk you through everything you need to know about bathroom leaks - from identifying common causes to choosing the right professionals for lasting solutions.

What Are Bathroom Leaks?

A bathroom leak occurs when water escapes from its intended path within your plumbing system or fixtures. Leaks may be visible, such as a dripping tap, or hidden behind walls, floors, or under tiles. The hidden ones are especially problematic as they often go unnoticed until significant damage has already occurred.


Bathroom leaks typically fall into two categories:


  • Fixture leaks: involving taps, showers, baths, or toilets.
  • Pipe leaks: involving concealed pipework beneath floors or within walls.


Recognising the type of leak is the first step toward a proper fix.

Common Causes of Bathroom Leaks

Leaking Taps and Showers

A worn washer or faulty seal can cause taps or showerheads to drip constantly. While seemingly minor, even a slow drip can waste thousands of litres of water annually.


Toilet Leaks

Toilets may leak from the base due to worn wax seals, or internally from tank issues. These leaks often go unnoticed until water stains appear on the floor or ceiling below.


Pipe Damage

Pipes hidden beneath floors and walls can crack, corrode, or burst due to age, freezing conditions, or excess water pressure. These leaks are harder to detect but potentially more destructive.


Damaged Grout and Sealant

In showers and around baths, cracked grout or failing silicone sealant allows water to seep into walls or subfloors. Over time, this leads to mould, rot, and structural weakening.


Faulty Appliances

If you have integrated washing machines or underfloor heating connected in the bathroom, faulty connections or valves may also cause leaks.

Signs You May Have a Bathroom Leak

  • Persistent damp or musty smell
  • Mould growth on walls, tiles, or ceilings
  • Peeling paint or bubbling wallpaper
  • Water stains on ceilings or walls below the bathroom
  • Loose or cracked tiles around showers or baths
  • Sudden spikes in your water bill



Catching these signs early can save you from costly repairs later.

One of the main calls that most plumbers receive every year, is the question ‘why is my boiler losing pressure?’. There could be many reasons as to why the boiler may be losing pressure, but the main factor in why it could be is that there could be a leak in the system somewhere. Some of the parts that could be leaking, could be the radiator valve, a pipe or something else that could be allowing the water to escape the system, then causing the loss of pressure within the boiler. However, they are not the only things that could cause a boiler to lose their pressure. There could be a problem with the valve on the boiler that could have possibly started to fail, in turn causing a drop in the pressure inside the boiler.
