What to Do Next

Step-by-Step Action Plan

Follow these steps before calling a technician — you may be able to resolve the issue yourself.

1

Inspect Visible Plumbing

Start by checking all visible pipes, faucets, and fixtures for signs of moisture or dripping. Pay attention to joints and connections.

2

Check Water Meter

Turn off all water fixtures and check your water meter. If it continues to move, you likely have a leak somewhere in your plumbing.

3

Look for Water Stains

Investigate the areas below your bathroom, such as ceilings or walls, for water stains, which indicate leaks from above.

4

Evaluate Caulking and Grout

Inspect the caulking around your tub, shower, and sink, as well as the grout between tiles. Look for cracks or gaps that could permit water to escape.

5

Test for Toilet Leaks

Add a few drops of food coloring to your toilet tank and wait 30 minutes. If the color appears in the bowl, you have a leak.

Pro Tip
Always turn off power to the unit at the breaker before inspecting any components. Safety first — even for simple checks.

Common Questions
How can I tell if I have a hidden leak in my bathroom?
Checking for hidden leaks can be done by monitoring your water meter, inspecting for water stains, and listening for sounds of dripping when all fixtures are off. The presence of wet spots on walls or ceilings can also indicate a leak. If you suspect a hidden leak but can't locate it, it's best to contact a professional for thorough detection.
What are the signs of a leaking toilet?
Signs of a leaking toilet include water pooling around the base, a constantly running toilet, and water stains on the floor. If you notice any of these symptoms, especially with increased water bills, it’s important to inspect the toilet seal and supply line for damage or wear.
Can I fix a bathroom leak myself?
Some minor leaks, such as dripping faucets or loose fittings, can be fixed by homeowners with basic tools. However, for more complex issues, like leaks behind walls or significant water damage, it's recommended to call a professional to ensure a proper and safe repair.
What causes mold growth in bathrooms?
Mold growth in bathrooms is often a result of excessive moisture from leaks, inadequate ventilation, or high humidity levels. Addressing leaks promptly and ensuring proper airflow can help prevent mold from developing.
