Only you can tell as there are a number of items in the drain path.
Remove the kick plate and find the leak.
May be as simple as replacing a clamp.

A small mirror and a flashlight come in handy when trying to track down leaks.
A mirror like the ones mechanics use, which is on a handle is ideal.
Yo could also tape a small mirror to a piece of doweling etc.
