3 Common Causes of Bathroom Leaks & Water Damage


It shouldn’t come as a surprise that one of the most common places for water damage is the bathroom. Due to the heavy water use and pipes galore, it is a hot spot for possible destruction. Knowing what to be aware of and watch for will go a long way in preventing possible damages.



  • Toilets are one of the most common clog problems. Only toilet paper should be flushed and all feminine hygiene products, paper towels, moist towelettes, toys, cotton balls, etc. should be avoided. Also be watchful of children around toilets.

  • Valves that shut off or stop the water flow to sinks, toilets, and showers should be checked regularly to ensure they are working properly. If you have an overflow, they are the quickest way to shut off the water. Keep an eye out for any signs of leaks like wetness or staining around the valves.

  • If there is a leak in the toilet wall pipes you may notice staining, bubbling, musty smells, or excess moisture. Always be on the lookout for these signs of water damage.

  • Use only septic safe toilet paper if you have a septic system.

  • Regularly check the toilet for any signs of cracks. Also check caulking to ensure seals are in good condition. Low water levels could also be an indicator there is a crack or clog. Always be on the lookout around the outer edge of the toilet for excess water, a moist, spongy floor, or if stains appear around the base.

Sink Leaks

  • Look under sinks for signs of leaks including cracked or warped flooring. Check for condensation or corrosion up around pipes. Replace rubber pipes with steel-braided lines for added security.

  • If there is a faucet leak, check the washers and gaskets and replace if necessary. If there is a continued problem, then the whole faucet may need to be replaced.

  • Caulking around the sink that is cracked or deteriorating should be replaced.

  • If you notice your sink is draining slowly, it may be clogged. Do not use cleaners, as they can do damage to your pipes. Use a natural remedy, a tool, or call a professional if needed.

  • Keep the area around the sink and faucet dry. Water that collects and sits can mean potential for damage.

Bathtub Overflow

  • Be sure to use bathmats to avoid areas of excess water buildup. Do not let water sit. Dry up any standing water and drain tubs immediately after use.

  • If you notice a crack or other damage, it may be necessary to replace your shower or tub. Even small hairline cracks can mean water getting in and causing damage.

  • Watch for excess water when children are in the tub. Wipe up any spills on floors or walls as soon as possible.

  • Replace shower curtains that are moldy or torn. Replace seals if they no longer work. Consider upgrading your shower head. Newer heads save on water and may help prevent potential water damage.


As little as any of us want to be fully acquainted with our bathrooms, it is a necessary step in preventing possible water damage. Taking the time to periodically check for leaks and make repairs when needed will be the best way to save you from the disasters that water can bring.
