You just noticed a leak, and you think it’s coming from a bathroom above. Do you need a plumber? Before you call, consider these questions:

Is it happening during or after someone who lives in the home has taken a shower?
Do you have a shower curtain or a door that could be left open?

If your answer is “yes,” (or if you are not sure), put a few towels on the floor right outside the shower. Keep an eye on them before and after showers to see if they get wet. The most common “leak” from bathrooms is human error: forgetting to keep that shower closed tight.
